Real carbonara has no cream in it. The silky sauce comes from egg yolks, finely grated cheese, rendered bacon fat and starchy pasta water. Everything depends on heat and speed: hot spaghetti is tossed with the egg mixture off the heat, so the yolks thicken without scrambling. In Rome they use guanciale and pecorino, but bacon and parmesan make an excellent version at home. This serves two because carbonara should be made right before eating; reheated, it loses its texture.

Method

Tap a step to mark it done.

  1. Bring 2 litres of water to the boil and add about 15 g of salt, a little less than usual since the bacon and cheese are salty.

  2. Cut the bacon into batons. Put them in a cold frying pan and cook over medium heat for 6-8 minutes until the fat has rendered and the bacon is golden. Take off the heat.

  3. In a bowl, beat the yolks, whole egg, most of the parmesan (keep a handful back) and plenty of freshly ground pepper, about ½ teaspoon. It should be a thick paste.

  4. Cook the spaghetti for 1 minute less than the packet says. Before draining, scoop out 150 ml of the cooking water.

  5. Tip the spaghetti into the pan with the bacon and fat and toss. Wait 30-60 seconds for the pan to cool slightly.

  6. Loosen the egg mixture with 2 tablespoons of hot pasta water, stirring quickly. Pour it over the spaghetti and toss vigorously with tongs for 1-2 minutes.

  7. Add more pasta water a spoonful at a time until the sauce is smooth, glossy and coats every strand. Serve immediately with the remaining cheese and more pepper.

Tips for success

  • Never add the eggs to a pan that's still on the heat; they'll scramble instantly.
  • If the sauce stays runny, set the pan over the lowest heat for 20-30 seconds, stirring constantly.
  • Don't pour away all the pasta water. Its starch binds the fat and egg into a smooth emulsion.
  • Skip the cream and garlic if you want the classic flavour.

Serving and storage

Serve right away in warmed bowls with extra parmesan and black pepper. A simple leafy salad dressed with olive oil and lemon is all it needs.

Carbonara is best eaten at once. Keep leftovers in the fridge for no more than a day and reheat gently with a splash of water, stirring.

Variations

  • With pecorino: swap half the parmesan for pecorino romano for a sharper flavour.
  • Mushroom: fry 150 g of sliced mushrooms along with the bacon.
  • Yolks only: use 5 yolks and no whole egg for an even richer sauce.

Frequently asked questions

How do you stop carbonara from scrambling?

Combine the pasta and egg mixture off the heat, after letting the pan cool for 30-60 seconds. Loosen the yolks with hot pasta water first and toss quickly and constantly. The heat of the pasta thickens the yolks without setting them.

Does carbonara have cream in it?

The traditional Italian recipe doesn't. The creaminess comes from yolks, grated cheese, bacon fat and starchy pasta water. Cream makes the sauce heavier and dulls the flavour, although many restaurants outside Italy add it.

Is it safe to eat carbonara with raw egg yolks?

The yolks are heated by the hot pasta to around 65-70°C, which is what thickens them. Use very fresh eggs from a reliable source and keep them refrigerated. If in doubt, choose pasteurised eggs.
