Spaghetti Carbonara

Real Roman carbonara has no cream in it — just eggs, Pecorino, guanciale and black pepper emulsified into a glossy sauce by the pasta water. Taking the pan off the heat before the eggs go in is what keeps them from scrambling.

How to Cook Spaghetti Carbonara

Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.

  1. Bring 4 litres of water to the boil and salt it — less heavily than usual, since Pecorino and guanciale both bring plenty of salt.

  2. Put the guanciale in a cold, wide pan and set it over medium-low heat. Rendering slowly from cold gives you crisp cubes and a pool of clear fat instead of scorched edges. This takes 8 to 10 minutes.

  3. Toast the cracked pepper in a dry corner of the pan for 30 seconds, until fragrant. Remove the pan from the heat.

  4. Whisk the yolks, whole egg and Pecorino in a bowl until it forms a thick, sandy paste with no lumps.

  5. Cook the spaghetti until 1 minute short of al dente, then reserve 300 ml of the cloudy cooking water.

  6. Temper the egg mixture by whisking in 60 ml of the hot pasta water in a thin stream — this warms the eggs gently so they will not seize later.

  7. Drop the drained spaghetti into the pan of guanciale and fat, off the heat, and toss vigorously for 30 seconds to coat every strand.

  8. Pour in the egg mixture and toss continuously, adding splashes of pasta water until the sauce turns glossy and clings. If the pan has cooled too much, return it to the lowest heat for no more than 20 seconds at a time.

  9. Serve at once in warmed bowls with more Pecorino and a heavy crack of pepper.

Worth Knowing Before You Cook

If the eggs start to scramble, lift the pan off the heat at once and toss in another splash of the reserved pasta water. It will not turn fully smooth again, but it stops the curds getting worse; the real cure is keeping the pan off the heat when the eggs go in.

Pancetta is an acceptable substitute; smoked bacon is not, as the smoke bulldozes the Pecorino.

Warm your serving bowls. Cold ceramic drops the sauce temperature fast enough to make it grainy.

Keeping What's Left

Carbonara is a strictly à la minute dish and does not keep well; the emulsion breaks and the eggs firm up on chilling. If you must, refrigerate for 1 day and reheat in a pan over very low heat with a splash of water, tossing constantly.

Spaghetti Carbonara: Your Questions Answered

Why did my Spaghetti Carbonara scramble instead of turning into a sauce?

The pan was too hot when the egg mixture went in. Off the heat completely, or over the lowest possible heat, stirring constantly — the pasta’s own residual warmth is what cooks the egg into a sauce rather than curds. If it has already started to scramble, take it off the heat at once and stir in a splash of the reserved, starchy pasta water; it will not fully smooth out, but it stops it going further.

Treat it as a rough guide: part of the energy comes from foods, or weights per item, with no recorded source; sodium is not given, because the salt for the cooking water is in the ingredient list but most of it is poured away with the water, so no figure from the list would be honest.
