Spaghetti carbonara is proof that a handful of good ingredients beats a long ingredient list. Hot spaghetti, eggs, Pecorino Romano, guanciale, and black pepper come together in minutes into a glossy, golden sauce that coats every strand. There is no cream in an authentic carbonara, and once you taste the real version, you will not miss it.

The trick is temperature control: the eggs thicken into a sauce from the heat of the pasta, never turning into scrambled eggs. If you love creamy pasta dinners, try Creamy Garlic Parmesan One-Pan Pasta and Creamy Marry Me Chicken Pasta next for more weeknight pasta inspiration.

Why This Recipe Works

No cream needed: Eggs and cheese emulsify with starchy pasta water into a sauce that is rich, silky, and authentically Roman.
Guanciale brings the flavor: Cured pork jowl renders into crisp, salty bites that bacon cannot quite match.
Pasta water is liquid gold: A ladle of starchy water loosens the sauce and helps it cling to every strand.
Fast enough for a weeknight: The sauce comes together in the time the pasta boils, so dinner is ready in 25 minutes.

Ingredients

12 oz (340 g) spaghetti
5 oz (140 g) guanciale, diced (or pancetta)

1 cup (100 g) finely grated Pecorino Romano cheese, plus more for serving
2 teaspoons (4 g) coarsely ground black pepper, plus more for serving
1 teaspoon (6 g) fine salt, for the pasta water

How to Make Spaghetti Carbonara

Step 1: Boil the pasta

Bring a large pot of salted water to a boil and cook the spaghetti until just shy of al dente, about 1 minute less than the package directions. Reserve 2 cups (480 ml) of pasta water before draining.

Step 2: Crisp the guanciale

While the pasta cooks, add the diced guanciale to a cold large skillet and cook over medium heat for 6 to 8 minutes, stirring often, until crisp and golden. Remove the skillet from the heat and let it cool for 1 minute.

Step 3: Whisk the egg and cheese sauce

In a bowl, whisk the egg yolks, whole egg, Pecorino Romano, and black pepper into a thick paste. Add a splash of warm pasta water and whisk until smooth and pourable.

Step 4: Toss everything together

Add the drained spaghetti to the skillet with the guanciale and toss to coat in the rendered fat. Pour in the egg mixture and toss vigorously, adding pasta water a splash at a time, until a glossy sauce coats the pasta. Serve immediately with extra Pecorino and black pepper.

Tips

Work off the heat: Keep the skillet off direct heat when adding the eggs so they thicken gently instead of scrambling.
Save more pasta water than you think: You may need up to 1 cup (240 ml); it is the key to a silky sauce.
Use room-temperature eggs: Cold eggs thicken unevenly. Set them out while the water boils.
Serve right away: Carbonara waits for no one. Warm the bowls and plate the pasta the moment the sauce comes together.

Storage

Carbonara is best eaten fresh, but leftovers can be refrigerated in an airtight container for up to 2 days. Reheat gently in a skillet over low heat with a splash of water, stirring constantly, until just warmed through. Do not microwave on high, which will scramble the sauce. Freezing is not recommended.

Frequently Asked Questions

Does authentic carbonara have cream?

No. Classic Roman carbonara gets its creaminess from eggs, Pecorino Romano, and starchy pasta water. Cream is a common shortcut, but it dulls the sharp, salty flavor of the cheese and guanciale.

Can I use bacon instead of guanciale?

Yes, in a pinch. Bacon works, but it is smokier and saltier than guanciale. Use thick-cut bacon and drain off a little of the fat if the pan looks greasy. Pancetta is the closer substitute.

Why did my carbonara turn into scrambled eggs?

The pan was too hot when the eggs went in. Take the skillet off the heat, let it cool for a minute, and toss quickly with pasta water. The residual heat of the pasta is enough to thicken the sauce.

Can I make carbonara ahead?

Not really. The sauce is made in the pan in the last two minutes and sets quickly. Prep the cheese, eggs, and guanciale ahead, then cook the pasta and finish the dish just before serving.
