Before You Begin
Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
Cook Pasta
Bring salted water to a boil. Cook spaghetti until al dente. Reserve 1 cup pasta water before draining.
Prepare Egg Mixture
In a bowl, whisk egg yolks, whole egg, cheeses, and pepper until smooth.
Cook Pork
In a skillet over medium heat, Cook guanciale or pancetta over medium heat until crispy and the fat has rendered, about 5–7 minutes, stirring occasionally. Remove skillet from heat. Combine Pasta + Fat
Add hot pasta directly to skillet off heat and toss to coat.
Create Sauce Safely
Pour egg mixture over pasta while skillet remains off heat. Toss continuously until sauce thickens and becomes glossy. Residual heat from the hot pasta gently cooks the eggs as they emulsify with the cheese and pasta water to form a smooth sauce. Add pasta water gradually as needed. Serve
Serve immediately. Refrigerate leftovers within 2 hours.
