A true Roman classic — silky egg sauce, crispy guanciale, and sharp Pecorino Romano. No cream, ever. This is the only carbonara recipe you'll ever need: simple, fast, and absolutely unforgettable.
In a bowl, whisk together egg yolks, whole egg, grated Pecorino, and Parmesan. Season generously with black pepper. Set aside.
In a large pan over medium heat, cook diced guanciale until crispy and golden. Remove from heat and let it cool slightly — do NOT discard the rendered fat.
Boil spaghetti in well-salted water until just al dente (1 minute less than package says). Reserve 1 cup of pasta cooking water before draining.
Add hot drained pasta to the guanciale pan (off heat). Pour egg mixture over pasta, tossing constantly. Add pasta water splash by splash to create a silky, creamy sauce. Work fast!
Plate into warm bowls. Top with extra Pecorino and a final generous crack of black pepper. Serve at once.
The secret is temperature control. Never add eggs to a hot pan — always remove from heat first, or you'll get scrambled eggs. The residual heat from the pasta and pan is enough to cook the sauce perfectly.
