Silky ribbons of pasta coated in a lush butter and Parmesan sauce make this a beloved family comfort dish. This mediterranean classic is rich and indulgent, best enjoyed as an occasional treat.
Bring a large pot of salted water to a boil over high heat. Add the fettuccine and cook until al dente, stirring occasionally, about 8-10 minutes.
While the pasta cooks, melt the unsalted butter in a large skillet over medium-low heat. Add the heavy cream and stir gently until the mixture is warmed and combined.
Lower the heat to prevent scorching and slowly whisk in the grated Parmesan cheese, allowing it to melt smoothly into the sauce. Stir constantly for a silky texture.
Drain the cooked fettuccine, reserving 1/4 cup pasta water. Add the pasta directly to the skillet with the alfredo sauce, tossing gently to coat. If the sauce is too thick, add pasta water a tablespoon at a time to loosen.
Season with salt, black pepper, and a pinch of nutmeg. Continue tossing over low heat for 1-2 minutes until the pasta is glossy and well-coated. Serve immediately while hot.
