Ingredients

Servings
4
  • 400g spaghetti
  • 200g pancetta
  • 4large egg_yolk
  • 2large egg
  • 100g pecorino, finely grated
  • 2tsp black_pepper, freshly ground
  • 1tbsp salt, for pasta water

Equipment Needed

  • stockpot
  • saute_pan

Instructions

  1. 1

    Bring a large pot of well-salted water to a boil. Cook spaghetti according to package directions until al dente, reserving 1 cup of pasta water before draining.

  2. 2

    While pasta cooks, cut guanciale into small cubes or strips. Place in a cold, large skillet and cook over medium heat until the fat renders and the meat becomes crispy, about 8-10 minutes.

  3. 3

    In a bowl, whisk together the egg yolks, whole eggs, grated pecorino, and a generous amount of freshly ground black pepper until smooth.

  4. 4

    Remove the skillet from heat. Add the drained hot pasta directly to the guanciale, tossing well to coat in the rendered fat.

  5. 5

    Working quickly while the pan is off heat, pour the egg and cheese mixture over the pasta and toss vigorously. The residual heat will gently cook the eggs into a creamy sauce. Add pasta water a splash at a time if needed to achieve silky consistency.

  6. 6

    Serve immediately in warm bowls, topped with extra pecorino and freshly cracked black pepper.

Tips

  • The key is adding the egg mixture off heat to avoid scrambling. The residual heat from the pasta creates the silky sauce.
  • Traditional carbonara uses guanciale (cured pork jowl), but pancetta is an acceptable substitute. Never use bacon as it's too smoky.
  • Never add cream - authentic carbonara gets its creaminess solely from eggs and cheese emulsified with pasta water.
