Cook the pasta: Boil the spaghetti in salted water according to the package instructions until al dente. Remember to reserve 1–2 cups of pasta water before draining.
6 ounce spaghetti
Sauté the pepper: In a skillet over medium heat, melt 2 tablespoons of butter. Add the black pepper and sauté for about 1 minute, just enough to release its rich aroma.
3 tablespoons butter, 1 teaspoon black pepper
Combine the ingredients: Add ½ cup of the reserved pasta water to the skillet. Toss in the cooked pasta, along with another tablespoon of butter. Lower the heat and sprinkle in the cheese, tossing the pasta until it’s evenly coated and the cheese melts into a smooth, creamy sauce. If needed, add more reserved pasta water to achieve the perfect silky texture.
1 cup parmesan
Serve immediately: Plate the pasta while it’s hot and enjoy this simple, indulgent dish right away!
