Start by gathering all your ingredients, ensuring everything is prepped and ready to go.
In a large pot, bring lightly salted water to a vigorous boil. Add the fettuccine and allow it to return to a boil. Cook the pasta over medium heat until it reaches an al dente texture, which should take about 8 to 10 minutes.
Once cooked, drain the fettuccine and return it to the pot. While the pasta is still warm, add the butter pieces, Parmesan cheese, and season with salt and freshly ground black pepper. Toss everything together until the butter melts and the noodles are thoroughly coated.
Serve the buttered noodles immediately while they're hot, and savor the rich, comforting flavors. Enjoy!
