Ingredients:
- 1 pound (450g) spaghetti or bucatini
- 4 ounces (115g) guanciale, cut into ¼-inch dice (or pancetta as a substitute)
- 3 large egg yolks
- 1 large whole egg
- 1 cup (100g) finely grated Pecorino Romano cheese, plus more for serving
- Freshly ground black pepper, to taste
- Salt to taste (careful - guanciale/pancetta and Pecorino are salty!)
Instructions:
- Bring a large pot of heavily salted water to a boil. Add the pasta and cook according to package directions until al dente. Reserve about 1 cup of pasta water before draining.
- While the pasta cooks, heat a large skillet over medium heat. Add the diced guanciale/pancetta and cook until crispy and golden brown, rendering out the fat. Remove from heat and set aside, reserving the rendered fat in the pan.
- In a mixing bowl, whisk together the egg yolks, whole egg, and Pecorino Romano cheese. Season generously with freshly ground black pepper.
- Drain the pasta and immediately add it to the skillet with the rendered guanciale/pancetta fat. Toss to coat. Quickly pour the egg mixture over the hot pasta, tossing constantly and vigorously to create a creamy sauce. Add a little of the reserved pasta water at a time to thin the sauce if needed and prevent the eggs from scrambling. The goal is a silky, emulsified sauce that coats the pasta.
- Serve immediately, garnished with more freshly grated Pecorino Romano cheese and freshly ground black pepper.
