Ingredients:
- 8 tablespoons (113g) Unsalted Butter, cold and cut into cubes
- 1 cup (100g) Finely Grated Parmesan Cheese, freshly grated is crucial
- 1 pound (454g) Pasta, preferably Fettuccine, cooked according to package directions, reserving 1 cup (240ml) of pasta water
- Freshly Ground Black Pepper, to taste
- Pinch of Salt, optional
Instructions:
- Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente, reserving 1 cup of pasta water before draining. Keep pasta warm while you prepare the sauce.
- In the skillet over medium-low heat, melt the butter. Be careful not to brown it.
- Add the drained pasta to the skillet with the melted butter. Immediately sprinkle in about half of the grated Parmesan cheese.
- Toss the pasta and cheese rapidly, adding small splashes of the reserved pasta water at a time. Continue tossing and adding pasta water until the cheese melts and the sauce becomes smooth, creamy, and clings to the pasta.
- Remove from heat. Stir in the remaining Parmesan cheese and season with freshly ground black pepper and a pinch of salt if needed (taste before adding!). Serve immediately.
