How to Make Chiles Rellenos

Chiles rellenos are whole poblano peppers, roasted and peeled, stuffed with melting cheese, dipped in a fluffy egg batter, and fried until golden, usually served under a light tomato sauce. It is a central Mexican dish that shows up on home tables and restaurant menus alike, and the poblano itself, mild with a slight vegetal bitterness, is what makes the dish work rather than any one topping.

Done right the pepper stays intact, the batter puffs into a light shell rather than a heavy crust, and the cheese pulls when you cut in. Done wrong you get a soggy, oil-logged pepper, which almost always traces back to skipping the peel or under-heating the oil.

Peeling the Pepper Actually Matters

Roast the poblanos until the skin blisters black all over, then steam them in a covered bowl or bag for at least 10 minutes before peeling. Leaving even small patches of skin on makes the batter slide off in the fryer, and it adds a bitter, papery texture that a lot of home versions get wrong by rushing the steaming step.

Chiles Rellenos

Serves 4 | Prep: 30 minutes | Cook: 25 minutes | Total: 55 minutes

Ingredients

4 large poblano peppers
8 ounces Oaxaca or Monterey Jack cheese, cut into sticks
4 large eggs, separated
1/4 cup all-purpose flour, plus more for dredging
1/4 teaspoon salt
1 cup vegetable oil, for frying
1 cup tomato sauce (from ripe tomatoes, onion, and garlic, simmered and blended)
1/4 cup chopped white onion, for the sauce
1 clove garlic, for the sauce

Method

Roast the poblanos directly over a flame or under a broiler, turning until blackened on all sides.
Place the roasted peppers in a covered bowl and steam for 10 minutes, then peel off the skins.
Cut a slit down one side of each pepper and remove the seeds, keeping the pepper whole.
Stuff each pepper with cheese sticks and press the slit closed.
Beat the egg whites to stiff peaks, then fold in the yolks, flour, and salt to make a light batter.
Dredge each stuffed pepper in flour, then dip fully in the egg batter.
Fry in hot oil, turning gently, for 3 to 4 minutes until golden on all sides. Drain on paper towels.
Simmer the tomato sauce with onion and garlic for 10 minutes, then blend smooth and warm through.
Serve the peppers with warm tomato sauce spooned over top.

Tips, Variations, and Storage

Roast and peel the poblanos up to a day ahead and refrigerate them wrapped, which actually makes assembly faster later. Ground beef or shredded chicken can be added alongside the cheese for a heartier filling. Fried peppers are best eaten right away, since the batter softens quickly, but leftovers reheat reasonably well in a hot oven.

Frequently Asked Questions

Can I skip frying and bake the peppers instead?

You can bake stuffed, unbattered peppers with cheese on top for an easier weeknight version, but you lose the crisp egg shell that defines a true chile relleno.

What if my batter is not puffing up?

The oil is likely not hot enough. It should be around 350 degrees Fahrenheit. Cold oil lets the batter absorb grease instead of setting quickly into a light shell.

Are poblanos spicy?

Generally mild, though heat can vary pepper to pepper. If you want a milder result, choose peppers with smooth, unblemished skin, which tend to run milder than wrinkled ones.
