01 - Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve ½ cup of pasta water, then drain the pasta.
02 - In a large skillet over medium heat, melt the butter with the olive oil. Add the minced garlic and sauté for 1–2 minutes, stirring constantly, until fragrant but not browned.
03 - Pour in the heavy cream and bring to a gentle simmer. Cook for 2–3 minutes, stirring occasionally.
04 - Add the grated Parmesan cheese, salt, pepper, and nutmeg. Stir until the cheese melts and the sauce thickens slightly.
05 - Add the cooked pasta to the skillet, tossing to coat in the sauce. If needed, add reserved pasta water a little at a time until the sauce reaches your desired consistency.
06 - Remove from heat and stir in the chopped parsley.
07 - Plate immediately, garnished with extra Parmesan and additional parsley if desired.
