Spaghetti Carbonara

Instructions

1. 1

   Bring a large Pot of water to a boil. Add the Kosher Salt and cook the Spaghetti according to package directions until al dente (usually 1–2 minutes less than the package time). Before draining, reserve at least 1 full cup of pasta cooking water — this starchy water is essential for your sauce.

2. 2

   While the pasta cooks, whisk together the 2 whole eggs and 2 extra egg yolks in a medium Mixing Bowl. Add the grated Pecorino Romano and Parmesan and whisk until you have a thick, smooth paste. Season with the coarsely ground black pepper. Set aside at room temperature.

3. 3

   Place the guanciale (or pancetta) in a large, cold Skillet. Turn the heat to medium and cook, stirring occasionally, until the fat has rendered and the pieces are golden and slightly crispy, about 6–8 minutes. Remove the Skillet from heat and let it cool for 2 minutes — this is a critical step to avoid scrambling the eggs later.

4. 4

   Drain the Spaghetti and immediately add it to the Skillet with the guanciale (off the heat). Toss well with Tongs to coat the pasta in the rendered fat.

5. 5

   Add a splash of the reserved pasta water (about 1/4 cup) to the Skillet and toss again. The pasta should cool slightly and the pan should no longer be smoking hot — you want it warm, not scorching.

6. 6

   Pour the egg-and-cheese mixture over the pasta. Using Tongs, toss quickly and continuously while adding more pasta water a splash at a time (up to 3/4 cup total) until a glossy, creamy sauce coats every strand. The residual heat from the pasta and pan will gently cook the eggs into a silky sauce — keep tossing and never let it sit still. If it looks too thick, add more pasta water. If it looks too thin, keep tossing — it will tighten as it cools slightly.

7. 7

   Taste and adjust salt if needed (the cheese and guanciale are already salty, so you may not need any). Divide into warm bowls, finish with an extra grating of Pecorino Romano and Parmesan, and a generous crack of black pepper. Serve immediately.
