How to Make Spaghetti Carbonara
Real carbonara has no cream. It's a silky emulsion of eggs, cheese, and pasta water — and when done right, it's one of the most impressive things you can put on a plate. Master this, and you'll have a signature dish for life.
Total time: 25 min · Servings: 2 portions
Ingredients
- 200g spaghetti or rigatoni
- 150g guanciale (or pancetta if unavailable)
- 3 large egg yolks + 1 whole egg
- 60g Pecorino Romano (finely grated, plus extra for serving)
- 30g Parmigiano-Reggiano (finely grated)
- Freshly cracked black pepper (generous — this is a key flavour)
- Salt for pasta water (not for the sauce — the cheese and guanciale are salty enough)
Instructions
-
Prepare the egg mixture: In a bowl, whisk together the egg yolks, whole egg, and grated cheeses until smooth and creamy. Add a generous amount of freshly cracked black pepper (about 1 tsp). Set aside.
Tip: This mixture should be at room temperature when you combine it with the pasta. Cold eggs scramble on contact with hot pasta. -
Cook the guanciale: Cut guanciale into 1cm strips or small cubes. Place in a cold pan and cook over medium-low heat for 8–10 minutes, stirring occasionally, until the fat renders out and the meat is golden and crispy. Remove from heat.
Tip: Start in a COLD pan. This renders the fat slowly and evenly. Don't use oil — the guanciale provides its own. -
Cook the pasta: Boil the spaghetti in generously salted water (it should taste like the sea). Cook 1 minute LESS than the package says — the pasta finishes cooking in the sauce.
Tip: Before draining, scoop out a full mug of starchy pasta water. This is your insurance policy for a silky sauce. -
Combine: Transfer the hot pasta directly into the guanciale pan (heat OFF). Toss to coat in the rendered fat. Wait 30 seconds for the pasta to cool SLIGHTLY (this prevents scrambling), then pour in the egg and cheese mixture.
Tip: The pan must be OFF the heat when you add the eggs. This is the #1 mistake people make. The residual heat of the pasta and pan is enough to gently cook the eggs into a creamy sauce. -
Emulsify: Toss vigorously, adding pasta water 1 tablespoon at a time, until the sauce is silky, glossy, and coats each strand. It should look like liquid gold.
Tip: The sauce thickens as it cools. If it gets too thick, add more pasta water. If it looks watery, keep tossing — the starch and cheese will emulsify it. -
Serve immediately: Plate immediately (carbonara waits for nobody). Top with extra Pecorino and a final aggressive crack of black pepper.
Tip: Carbonara doesn't reheat well. Make it, serve it, eat it. That's the ritual.
Pro Tips
- If you scramble the eggs (it happens to everyone at least once): the pan was too hot. Next time, remove the pan from heat completely before adding the egg mixture.
- Pecorino Romano is the traditional cheese. Parmesan alone makes it a different (still good) dish. The sharp, salty bite of Pecorino is what makes carbonara taste like carbonara.
- Guanciale (cured pork cheek) is traditional. Pancetta is a fine substitute. Regular bacon works in a pinch but is smokier than authentic.
Frequently Asked Questions
Why did my carbonara turn into scrambled eggs?
The pan was too hot when you added the egg mixture. Remove the pan from all heat before adding the eggs. The residual heat of the pasta (around 70°C) is enough to create a creamy emulsion. Direct stove heat (above 80°C) scrambles them.
Does real carbonara have cream?
No. Authentic Italian carbonara contains no cream. The creamy texture comes from the emulsion of egg yolks, cheese, pasta water starch, and rendered pork fat. Adding cream is a common non-Italian adaptation.
Can I use bacon instead of guanciale?
Yes, but the flavour will be different. Bacon is smoky; guanciale and pancetta are not. For the most authentic result, use guanciale. For a still-delicious version, use unsmoked pancetta or even regular bacon.
What pasta shape is best for carbonara?
Spaghetti is classic. Rigatoni is the Roman favourite for carbonara — the tubes trap the sauce beautifully. Bucatini (hollow spaghetti) also works excellently.
