Spaghetti carbonara is a Roman pasta dish made by tossing hot pasta with raw egg, hard cheese, black pepper, and cured pork until the egg turns into a silky sauce, never scrambled curds. It comes together in the time it takes to boil the pasta, using almost nothing else.
The dish is native to Rome, and there's no cream in a real version, despite what a lot of recipes outside Italy will tell you. The most common origin story ties it to Roman shepherds and charcoal workers (carbonai), who carried eggs, cured pork, and hard cheese into the hills because none of it needed refrigeration.
Traditional versions use guanciale (cured pork jowl) and pecorino romano, both sharper and fattier than the bacon and parmesan substitutions you'll see elsewhere. If you can't find guanciale, pancetta is the closest stand-in.
What Actually Matters
The whole dish lives or dies on how you combine the egg mixture with the pasta. Add it to pasta that's too hot, straight off the heat, and the eggs scramble into little curds. Add it off the heat, with the pan cooled and a splash of starchy pasta water stirred in first, and the eggs turn into a sauce that coats every strand. Take the pan off the burner entirely before you add the egg and cheese mixture, and stir constantly. That's the one move that separates carbonara from scrambled egg pasta.
Spaghetti Carbonara Recipe (Serves 4)
Prep time: 10 minutes. Cook time: 20 minutes. Total time: 30 minutes.
- 1 lb spaghetti
- 8 oz guanciale or pancetta, cut into small strips
- 4 large eggs
- 1 cup finely grated pecorino romano, plus more for serving
- 1 tsp freshly cracked black pepper, plus more to taste
- 1 tsp kosher salt, for the pasta water
- Bring a large pot of well salted water to a boil and cook the spaghetti until just shy of al dente.
- While the pasta cooks, cook the guanciale in a large skillet over medium heat until crisp and the fat has rendered, about 8 minutes. Turn off the heat.
- In a bowl, whisk together the eggs, pecorino romano, and black pepper until smooth.
- Reserve 1 cup of pasta water, then drain the spaghetti.
- Add the hot spaghetti to the skillet with the guanciale, off the heat, and toss to coat in the rendered fat.
- Let the pasta cool for about a minute, then pour in the egg and cheese mixture, stirring constantly and adding splashes of reserved pasta water until the sauce turns glossy and coats the noodles.
- Serve immediately with extra pecorino and black pepper on top.

Tips, Variations, and Storage
Don't rush the cooling step before you add the egg mixture. If your kitchen is cold, let the pasta sit off heat for closer to two minutes. Some cooks add a whole egg plus extra yolks instead of four whole eggs, which gives a richer, less rubbery sauce. Carbonara doesn't reheat well because the egg keeps cooking, so it's best made fresh. If you do have leftovers, warm them gently in a skillet over low heat with a splash of water, stirring the whole time.
Frequently Asked Questions
Can I use bacon instead of guanciale?
You can, but the flavor and texture will be different. Guanciale is fattier and less smoky than bacon, and it renders differently in the pan. Pancetta is the closer substitute if you can't find guanciale.
Why did my carbonara turn out scrambled?
The pan was too hot when you added the egg mixture. Always pull the pan off the heat and let the pasta cool slightly before stirring in the eggs and cheese.
Is there cream in real carbonara?
No. The creaminess comes entirely from egg, cheese, and starchy pasta water. Cream isn't part of the traditional Roman recipe.
Can I make carbonara ahead of time?
Not really. It's a dish meant to be eaten right after it's tossed together, since the egg sauce doesn't hold or reheat cleanly.
What pasta shape works besides spaghetti?
Rigatoni and bucatini are both traditional alternatives, and their ridges or hollow centers hold the sauce well.
