How to Cook Steak: The Ultimate Pan Seared Steak Recipe & Science Guide

How to cook steak in a pan comes down to a thick cut, a dry surface, a very hot heavy skillet and frequent flips. For a pan seared steak at least 1 inch thick (1 1/2 inches is better), pat it dry, sear it hard, let it sit for the first minute, then flip it every 30 to 60 seconds, add butter near the end and pull it at 120 to 125°F (49 to 52°C) for medium-rare. Rest it 5 to 10 minutes. USDA's safe minimum for beef steaks is 145°F (63°C) with a rest of at least 3 minutes, so anything lower is the cook's call.

The rest of this guide covers the physics of the crust, the chemistry of the deglaze and a pan sauce built on weight instead of spoonfuls. The full recipe for four comes after the science, with imperial and metric amounts.

Why a Steak Recipe Written in Minutes Falls Short

A recipe that says "sear 3 minutes per side" assumes your pan, your burner and your steak match the writer's. They rarely do. Pan metal, pan thickness, how cold the steak is and how much fat is in the skillet all change what 3 minutes means.

Spoon measures fail the same way. A tablespoon of wine goes into the pan, but how much water is left after the reduction depends on the heat and the pan. A sauce measured in spoonfuls changes every time it is made.

So treat the stove like a bench. Control what you can measure: how dry the surface is, how much heat the pan stores, which fat goes in when, the internal temperature of the meat and the weight of the sauce. Everything below hangs on one of those.

The Physics of a Steakhouse Crust

How to get Maillard reaction on steak?

Get the surface hot enough and dry enough. The Exploratorium's page on searing steak says Maillard reactions, the chemistry between amino acids and sugars that makes the brown crust, happen above 140°C (280°F). It also notes that liquid water can only reach 100°C (212°F), which is why boiled meat never browns.

NC State food scientist Gabriel Keith Harris gives the working number for a home cook. In a July 2024 NC State CALS article, he says the surface heats to about 350°F (177°C) or more after the moisture leaves, and that is where Maillard happens quickly. Past that point a surface goes from brown to black, because the food has moved beyond Maillard and is breaking down.

Why surface water is the enemy

According to Harris, the water in the meat keeps the surface cool, and the surface climbs only once that water is gone. Every drop on a wet steak has to boil off before browning can start. Until it does, the surface sits at the boiling point and the pan's heat goes into making steam.

The loud sizzle when a steak hits the pan is that water turning to steam. The Exploratorium makes a second point from the same sound: if a crust sealed in the juices, the sizzle would stop. Searing does not seal in juices. It browns the surface for flavor, and a seared steak likely ends up lighter than an unseared one cooked to the same temperature. The Exploratorium suggests testing it by weighing two steaks before and after cooking.

How long to dry brine steak?

Salt the steak no less than 40 minutes ahead of the pan, and up to 24 hours ahead is the house method. Serious Eats, in J. Kenji López-Alt's butter-basted steak recipe, says salt first pulls liquid to the surface, where it dissolves the salt into a concentrated brine. Roughly 25 to 30 minutes after salting, the steak is in the worst state for searing, because that moisture evaporates off and leaves a tough, stringy crust. Wait longer and, he says, the juices are reabsorbed, which seasons the meat deeper.

The steak should not sit in that middle window. Either salt right before the pan or salt well ahead. For the longer wait, put the salted steak on a rack over a tray, uncovered, in the refrigerator. The cold, dry air pulls water off the surface, which is the part the crust needs gone.

Use salt by weight. A common cook's starting point is 1 percent of the steak's weight, so 900 g of steak takes 9 g of kosher salt. Adjust it to taste. It is a rule of thumb, not a tested standard, which is why a kitchen scale is worth owning.

Can you dry brine steak too long?

This recipe stops at 24 hours. The Serious Eats recipe holds seasoned steaks loosely covered in the refrigerator for up to 3 days. None of the sources cited here tests a longer brine, so treat anything past 3 days as untested.

Do you rinse a dry brine off?

No. Rinsing puts water back on the surface, and that water has to boil off before the steak can brown. Pat the steak dry with paper towels, then cook it.

The counter rest does very little

Many cooks pull a steak out an hour or two early so it cooks evenly. The evidence says a thick steak barely warms in that time. America's Test Kitchen rested 1-inch rib-eyes on the counter and they reached only 52°F (11°C) after an hour and 62°F (17°C) after two. When those steaks were then seared hot and flipped once, the gray band under the crust looked as bad as on steaks that went in cold from the refrigerator. Serious Eats measured about 4°F (2°C) of warming at 30 minutes and about 9°F (4.5°C) at an hour, with cooking times and eating quality nearly identical to a steak cooked cold.

The only safety line this guide draws is USDA's. The USDA Food Safety and Inspection Service danger zone page says food should not sit out of the refrigerator past 2 hours, or past 1 hour in heat above 90°F, and that bacteria can double within 20 minutes at 40°F up to 140°F. The practical plan is to take the steak out, pat it dry and cook it.

Pan selection and thermal mass

A pan has two jobs in a sear: hold a lot of heat, and move it into the meat evenly. Handbook values from Engineering Toolbox show how the common metals compare. These are reference figures for the metals, not results from a cookware test.

Cast iron and carbon steel conduct heat almost equally, so any difference between those two pans comes from mass and thickness, not the metal. The heat a pan stores equals its mass times its specific heat times its temperature rise, which is why a thick, heavy pan holds more of it than a thin one made of the same metal. Stainless steel conducts poorly, so a tri-ply stainless pan depends on a core of a better conductor, usually aluminum, to spread the heat.

That stored heat matters because a fridge-cold steak, which America's Test Kitchen puts at about 40°F (4°C), pulls heat out of the pan the moment it lands. Serious Eats makes the same case for cast iron: heated until smoking, a heavy pan can practically sear a steak even when lifted off the burner. The 10.25-inch (26 cm) skillet in the set below fits one thick steak with room to flip it, so the recipe cooks the steaks in turn.

Cast iron gets its nonstick quality from seasoning. America's Test Kitchen, writing about cast iron, describes it as a coating of polymerized fat, many molecules thick, trapped in the pits of the metal and partly bonded to it. Heat plus oil builds it, more unsaturated oils polymerize more readily, and a pan heated too far can wear the coating down. Each time you cook in the pan with heat and oil, you add to it.

For a kit that covers searing and braising, the cast iron cookware set with Dutch oven, griddle and skillets includes a 10.25 inch skillet, an 8 inch skillet, a 5 quart Dutch oven with a lid and a 10.5 inch griddle. The listing describes the finish as a natural, easy release finish that improves with regular use. It does not say pre-seasoned, so plan on building the seasoning as you cook.

Do you sear steak with oil or butter?

Sear in oil, and add butter near the end. Serious Eats explains that when cooks say butter burns, the part that burns is the milk protein, the little white specks in melted butter. Those proteins burn whether they sit in butterfat or in oil, so mixing butter with oil does not raise the smoke point. The best medium for the sear is plain oil, with enough in the pan to cook the steak evenly.

Butter added a few minutes before the steak is done gives flavor and color without much time to burn. Left on too long, it produces acrid notes. Because butter carries milk proteins, it browns the steak further once it goes in.

Treat these as approximate. The same Wikipedia page warns that smoke points vary with free fatty acid and protein content, and calls smoke point a weak guide to how well an oil handles heat. Use the table to choose the sear fat: refined avocado oil stays well above the roughly 350°F where NC State says Maillard runs quickly. Butter waits for a different reason. Serious Eats points to its milk proteins, which burn at searing heat, so butter goes in once the crust is established.

Is it best to cook steak in oil or butter?

Use both, in order. Oil carries the sear, and butter finishes the steak for flavor. If you want a single fat, clarified butter has the milk solids removed and a much higher smoke point than whole butter.

How long do you pan sear steak?

A steak 1 1/2 inches thick takes about 8 to 10 minutes in the pan from start to pull, with frequent flips. The Serious Eats recipe, written for larger steaks, reaches a pale golden crust in about 4 minutes of flipping, then adds butter and finishes in 8 to 10 minutes total. The steaks in this guide are smaller, so start probing at 6 minutes and let the thermometer decide, not the clock.

Here is the order of play:

1. Heat the oil over high heat until it just begins to smoke.
2. Lay the steak in away from you so any splatter goes the other way.
3. Let it sit for the first minute so it releases cleanly from the pan.
4. Flip it every 30 to 60 seconds from then on.
5. Add butter, thyme and garlic once a pale golden crust has formed. Tilt the pan so the butter pools by the handle, and spoon it over the paler spots.
6. Keep flipping and basting until the thermometer reads your pull temperature.

The first minute is a cook's practice, not something a source proved. The tested evidence on flipping points toward moving the steak often. Harold McGee's frequent-flip tests were recreated by Dave Arnold in a 2009 Cooking Issues class write-up: a steak flipped every 5 seconds was done about 30 percent faster than one flipped once, cooked more evenly, and the once-flipped steak did not have a better crust.

Serious Eats' Leah Colins (July 15, 2026) flips thick steaks every 30 to 60 seconds. She reports that McGee's testing showed intervals as short as every 15 seconds work, and that Serious Eats' own tests found frequent flipping browns as well as one flip, with a more even interior. She also states how small the gain is. Kenji López-Alt's testing found that flipping once will not ruin a steak, and the differences are noticeable but subtle.

America's Test Kitchen's cold sear method flips every 2 minutes. That is a different approach, starting in a cold carbon steel or nonstick pan.

What is the 3-3-3 rule for steaks?

It is a grilling shorthand that splits the cook between direct and indirect heat. A skillet has no indirect side, so it does not translate to a pan. Use the pull temperatures below instead.

Doneness, rest and slicing

Cook to temperature, not time. Put an instant-read thermometer into the thickest part of the steak. Serious Eats notes that thick steaks keep rising after they leave the heat and suggests pulling a good 5 degrees before the final target.

The USDA says beef steaks should reach 145°F with a rest of at least 3 minutes, and that consumers may choose higher temperatures for personal preference. Every pull temperature in the table above that line is the cook's call. This recipe rests the steak 5 to 10 minutes, the same range the Serious Eats recipe uses, before it is sliced.

The Chemistry of the Deglaze

What fond is, and when it goes wrong

Fond is the dark film of browned meat that sticks to the skillet while a steak sears. Sohla El-Waylly's Serious Eats guide to pan sauces treats it as the base of the sauce. Add liquid, scrape, and most of the flavor is already in the pan. She sears in a cast iron or heavy stainless skillet for it, because fond forms by sticking and nonstick pans do not make much.

Fond has a color limit. Deep brown is flavor. Black means the surface went past Maillard, as Harris describes, and the burnt butter proteins add acrid notes, as Serious Eats warns. El-Waylly says a pan sauce taken far enough to burn the butter's milk solids is past saving.

How do I make a pan sauce?

Pour off most of the fat, soften shallot in what remains, scrape the fond up with wine, reduce the wine nearly dry, add stock and reduce again, strain, weigh, then whisk in cold butter by weight. The sections below explain why each step is there, and the recipe gives the amounts.

Liquids and acid

Any liquid will lift fond. El-Waylly notes that a splash of water and a pat of butter is a basic pan sauce, and that a splash of coffee does the job for redeye gravy. A better sauce uses wine and stock.

She reduces wine until it is almost dry, which the French call au sec. That cooks off the alcohol and concentrates the small amount of sugar in the wine, which gives the sauce body and helps keep it emulsified. Her test: drag a spoon across the pan, and when the streak stays for a moment before closing, the wine is ready for stock.

She also ties the quality of a pan sauce directly to the quality of the stock, and recommends homemade stock, or boxed stock with gelatin added. A teaspoon of red wine vinegar at the end is a taste adjustment, not chemistry: add it when the sauce tastes flat or heavy.

The deglaze timeline

These times are working guides, and the pan sets the real ones. Start the sauce while the steaks rest.

1. Pour off all but about 1 tablespoon (15 ml) of fat and lower the heat to medium. Cook the minced shallot in it for about 1 minute.
2. Add the wine and scrape the fond free. Reduce until almost dry, about 2 to 3 minutes.
3. Add the stock and simmer until it is reduced to a syrupy consistency, about 8 to 10 minutes.
4. Strain, weigh and finish with butter off the heat, as described below.

If the fond is black

Do not deglaze a black pan. The scrapings will taste bitter and acrid. Pour out the fat, wipe the pan, and build a smaller sauce in a clean saucepan from shallot, wine and stock. It will have less depth than a fond sauce, but it will taste clean.

Straining

Pour the reduced liquid through a fine mesh strainer into a small saucepan set on a kitchen scale. This catches the shallot, garlic, thyme and any blackened specks, and it puts the liquid exactly where it needs to be for weighing.

The Frictionless Sauce Ratio

What is the best sauce for steak?

For a steak cooked in a skillet, the best sauce is the one built in that skillet, because it carries the fond. A cream and brandy version made the same way is in our steak frites with peppercorn sauce. The pan sauce below is lighter and depends on butter instead of cream.

Emulsion math

America's Test Kitchen describes butter as 16 to 18 percent water and 80 percent butterfat. In plain butter, tiny water droplets sit in the fat. Whisk the butter into a little liquid and it reverses, with the fat broken into droplets held in the water. That swap lets a lot of butter turn into a sauce, and it is why a butter sauce tastes rich but not greasy. Oil in the same spot would separate and float.

That gives us arithmetic to work with. 20 g of butter holds about 16 g of butterfat (20 x 0.80) and about 3.2 to 3.6 g of water (20 x 0.16 to 0.18). Added to 100 g of reduced liquid, the sauce weighs 120 g and about 13 percent of it is butterfat (16 divided by 120, which is 13.3).

The 100:20 house ratio

The formula is 100 g of reduced liquid to 20 g of cold butter. Weigh the strained liquid, multiply by 0.2, and that is the butter in grams. It is a working proportion we chose, not a published standard. The arithmetic above shows what it means in the sauce. It does not prove this is the best ratio.

The ratio has a real limit. A pan sauce needs enough water left in it to emulsify. El-Waylly says a sauce that looks greasy has over-reduced, because too much water has evaporated, and the fix is a splash of water with vigorous simmering and stirring. If the strained liquid has gone past syrupy, add water first, then weigh again.

Cold butter, added gradually

America's Test Kitchen tested this on a white butter sauce that called for 8 tablespoons of butter, which is about 113 g, far more than our 20 g. Of the versions tried, a single one gave a sauce that thickened: cold butter, added a tablespoon at a time. Softened butter and all-at-once additions gave thin sauces that split. The explanation given is that cold butter melts slowly, which lets the whisk split the butterfat into fine droplets, and gradual addition slows the process further.

Sources disagree here. A Serious Eats beurre blanc recipe by Daniel Gritzer says the butter need not be added in increments, and that you can add it all at once without making the sauce more likely to break. This recipe follows the America's Test Kitchen method because it costs nothing, but cooks should know the evidence is split. The America's Test Kitchen cold butter test lays out their test in full.

Temperature limits

Sources do not agree on one temperature, so this guide gives none as fact. Serious Eats says a butter sauce breaks when it overheats and has to be kept warm, not hot. El-Waylly builds her pan sauce with vigorous bubbling to emulsify the butter, then warns that the milk solids will burn if the sauce goes too far. The house method is the cautious reading: take the pan off the heat before the butter goes in, keep the sauce warm and below a simmer, and take it off the heat again as soon as it looks glossy.

Finishing

Taste after the butter, not before, because the salt in the stock concentrates as it reduces. Add salt last. A properly emulsified sauce looks creamy, thick and opaque, according to El-Waylly, and a greasy look means it has broken. She finishes hers with soft herbs and black pepper once the butter is in, so parsley or chives go in at the end.

A teaspoon of red wine vinegar brightens a sauce that is flat. Mustard and garlic contain mucilage that can act as an emulsifier, according to a December 2023 explainer in The Conversation, but that was written about salad dressing. We leave both out of the formula so the 100:20 ratio is the only variable.

Pan Seared Steak with a Weighed Red Wine Pan Sauce

Serves 4. Prep 15 minutes, cook 35 minutes, total 50 minutes, plus at least 40 minutes (up to 24 hours) for the dry brine. Imperial and metric amounts are given together.

Ingredients

For the steak

• 2 boneless ribeye steaks, 1 1/2 inches (3.8 cm) thick, about 16 ounces (450 g) each, 32 ounces (900 g) in all
• 9 g kosher salt (1 percent of the steak weight; weigh it, because volume varies by brand)
• 1 teaspoon (2 g) coarse black pepper
• 1/4 cup (60 ml, about 55 g) refined avocado oil
• 2 tablespoons (28 g) unsalted butter
• 4 sprigs fresh thyme
• 2 cloves garlic (6 g), smashed

For the pan sauce

• 1 small shallot (40 g), minced
• 1/2 cup (120 ml, about 119 g) dry red wine
• 1 cup (240 ml, 240 g) good beef stock, preferably with gelatin or homemade
• 20 g cold unsalted butter (about 1 1/2 tablespoons), cut in small cubes. The amount is set by the weight of your reduced liquid, as in the method.
• Salt to taste
• Optional: 1 teaspoon (5 ml) red wine vinegar

Method

1. At least 40 minutes before cooking, and up to 24 hours ahead, pat the steaks dry. Season all sides and the edges with the salt (4.5 g per steak) and the pepper. Set them on a rack over a tray, uncovered, in the refrigerator. If you have less than 40 minutes, wait and salt right before the pan.
2. When ready to cook, pat the steaks dry again with paper towels. Do not rinse them.
3. Use a 10.25-inch (26 cm) cast iron or carbon steel skillet and cook the steaks one at a time. Serious Eats uses 1/4 cup of oil for large steaks in a 12-inch skillet, so this recipe splits that: heat half of the oil, 2 tablespoons (30 ml), over high heat until it just begins to smoke.
4. Lay the first steak in away from you. Leave it for the first minute. Then flip every 30 to 60 seconds with tongs until a pale golden crust forms, about 4 minutes in all.
5. Add half of the basting butter, 1 tablespoon (14 g), with half of the thyme and garlic. If the butter smokes hard, lower the heat to medium. Tilt the pan, spoon the foaming butter over the paler spots, and keep flipping and basting.
6. From about 6 minutes, check the thickest part with an instant-read thermometer. Pull at 120 to 125°F (49 to 52°C) for medium-rare or 130°F (54°C) for medium, usually 8 to 10 minutes in all. USDA's safe minimum for beef steaks is 145°F (63°C) with a rest of at least 3 minutes, so lower doneness is the cook's call.
7. Move the steak to a rack to rest. Pour off the used fat, wipe out any black bits, and repeat steps 3 to 6 for the second steak with the remaining oil, butter, thyme and garlic. Rest each steak 5 to 10 minutes before slicing, so the first rests while the second cooks.
8. Make the sauce in the second steak's pan while it rests. Pour off all but about 1 tablespoon (15 ml) of fat and lower the heat to medium. Add the shallot and cook about 1 minute. Add the wine, scrape up the fond, and reduce until almost dry, about 2 to 3 minutes.
9. Add the stock and simmer about 8 to 10 minutes, until syrupy. Strain through a fine mesh strainer into a small saucepan set on a scale and weigh it. Aim for about 100 g, though the formula scales to any weight. If it weighs more, simmer it down. If it is thicker than syrup, add a splash of water and weigh again.
10. Multiply the weight by 0.2 to get the butter in grams (100 g of liquid takes 20 g of butter). Take the saucepan off the heat. Whisk in the cold butter one cube at a time, adding the next when the last is almost melted. Keep the sauce warm and below a simmer. Taste, add salt, and add the vinegar if the sauce is flat.
11. Slice the steaks across the grain, pour any resting juices over them, and spoon about 30 g (2 tablespoons) of sauce per serving.

Make ahead. The dry brine in step 1 can run up to 24 hours. Strain the reduction the same day, then reheat it gently and whisk in the butter at serving time. Refrigerate leftovers in shallow containers within 2 hours and reheat to 165°F (74°C), which USDA lists for leftovers.

Substitutions. Strip steaks work in place of ribeye, and the nutrition below is calculated for ribeye. Without wine, use 1/2 cup (120 ml) more stock plus the vinegar, and expect less body, since wine sugars help thicken the sauce. Clarified butter works in the pan in place of the oil.

Allergens. Butter is dairy. Wine contains sulfites. Check the stock label.

Nutrition (estimated, per serving)

This is an estimate, not lab data. It counts all the oil, butter, salt and wine as eaten, even though much of the oil stays in the pan and some wine alcohol cooks off, so it errs high. It uses the FoodData Central entry for raw choice boneless ribeye, lean and fat together, and ignores the pepper.

Questions Cooks Ask

Does searing seal in the juices?
No. The Exploratorium explains that the sizzle is water leaving the steak, and that a crust adds flavor but does not keep moisture in.

Do I need a thermometer?
Yes. Cook to temperature, not time. Pull medium-rare at 120 to 125°F (49 to 52°C), medium at 130°F (54°C), and know that USDA's safe minimum for beef steaks is 145°F (63°C) with a rest of at least 3 minutes.

How long should a steak rest?
Rest this recipe's steaks 5 to 10 minutes before slicing. USDA's minimum rest at 145°F is at least 3 minutes.

Why is my pan sauce greasy?
It has over-reduced and lost the water it needs to emulsify. Add a splash of water and simmer while stirring, then take it off the heat.

What does the 100:20 ratio mean?
It means 100 g of reduced liquid to 20 g of cold butter, a working proportion we chose. Weigh the strained liquid, multiply by 0.2, and whisk in that weight of butter off the heat.

Systemize Your Station

A repeatable steak comes from a set-up you can reuse. Keep a scale, an instant-read thermometer, a heavy skillet and a sharp knife in the same place, and write the weights down. When the steak or the pan changes, you will know which number to adjust.

The knife is the last piece. After the rest, slice across the steak with a sharp blade. The stainless steel santoku chef knife with a 16 cm blade comes in six styles, and the listing says it is good for cutting boneless meat and should stay away from bones and frozen food. One style has a serrated edge, so choose a plain edge for slicing steak.
