Authentic Pasta Carbonara with Guanciale and Pecorino
Master the art of pasta carbonara with this Roman recipe. Use guanciale, pecorino, and egg yolks to create a silky, cream-free sauce that never scrambles.
A proper pasta carbonara is a masterclass in emulsion, relying on the heat of the pasta and rendered pork fat to transform raw egg yolks into a glossy, velvet-like sauce. Despite what supermarket jars might suggest, a classic carbonara contains absolutely no heavy cream, garlic, or onions.
The soul of this dish lies in the quality of its modest ingredients: sharp Pecorino Romano, black pepper, and guanciale (cured pork jowl). If you can't find guanciale, a thick-cut pancetta is a respectable substitute, but the funk of the jowl is what makes it an authentic carbonara.
The secret to success is the off-heat tempering trick. By combining the eggs and cheese in a separate bowl and adding the hot pasta to the mixture away from the stove, you ensure the eggs thicken without ever reaching the 'scrambled' stage.
Ingredients
The Pasta
- 400g (14 oz) Spaghetti or Rigatoni
- 1 tablespoon Kosher salt (for pasta water)
The Carbonara Base
- 150g (5.3 oz) Guanciale, skin removed and cut into 1/2-inch batons
- 4 large Egg yolks, room temperature
- 1 large Whole egg, room temperature
- 60g (2 oz) Pecorino Romano, finely grated, plus more for serving
- 2 teaspoons Freshly cracked black pepper, toasted briefly in a dry pan
Instructions
- 1
Boil a large pot of water, but salt it less than usual; the guanciale and pecorino are both quite salty.
- 2
Place the guanciale in a cold skillet and turn the heat to medium. Render the fat slowly until the pork is golden and crisp, about 8-10 minutes. Remove the pan from the heat and set aside.
- 3
Whisk the 4 yolks, 1 whole egg, grated Pecorino Romano, and toasted black pepper in a medium heat-proof mixing bowl until a thick paste forms.
- 4
Cook the pasta until it is very al dente—about 2 minutes less than the package directions.
- 5
Reserve 1 cup of starchy pasta water, then drain the pasta.
- 6
Add the hot pasta directly into the skillet with the guanciale and its rendered fat. Toss for 30 seconds to coat the strands.
- 7
Pour the hot pasta and pork mixture into the bowl with the egg and cheese paste. Do not do this in the hot skillet, or the eggs will scramble.
- 8
Vigorously toss the pasta while adding 2-4 tablespoons of the reserved pasta water. Continue tossing until the cheese melts and the eggs emulsify into a creamy, glossy sauce that clings to the pasta.
- 9
Serve immediately on warmed plates with an extra dusting of Pecorino Romano and more black pepper.
Tips
- → Use room temperature eggs to prevent the sauce from cooling down too quickly before it has a chance to emulsify.
- → Toast your black pepper in a dry pan for 60 seconds before adding it to the eggs; it releases essential oils that make the flavor pop.
- → If the sauce looks too thick or 'tacky,' add more pasta water one tablespoon at a time. The starch in the water is the 'glue' for the emulsion.
- → Never use pre-grated cheese. The cellulose coatings used to prevent clumping will stop the cheese from melting smoothly into the sauce.
FAQ
Why does my pasta carbonara keep turning into scrambled eggs?
This happens when the eggs are exposed to direct heat. Always mix your eggs and cheese in a separate bowl and add the hot pasta to that bowl off-heat. The residual heat of the pasta is enough to cook the eggs safely without curdling them.
Can I use Parmesan instead of Pecorino?
You can, but Pecorino Romano is saltier and funkier, which is traditional. If you find Pecorino too strong, a 50/50 mix of Parmesan and Pecorino is a common and delicious middle ground.
How do I reheat leftover carbonara?
Carbonara is best eaten immediately. If you must reheat it, do so very gently with a splash of water in a pan over low heat, stirring constantly. High heat will definitely scramble the egg sauce.
