Bring a large pot of salted water to a boil. Cook the fettuccine pasta according to package instructions until al dente. Reserve 1 cup of pasta water, then drain the pasta and set aside.
In a large skillet over medium heat, melt the unsalted butter. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Stir in the pumpkin puree and heavy cream, mixing well until combined. Let it simmer for about 3-4 minutes, stirring occasionally.
Add the grated Parmesan cheese and nutmeg to the sauce, stirring until the cheese is melted and the sauce is creamy. If the sauce is too thick, gradually add some reserved pasta water until the desired consistency is achieved.
Season the sauce with salt and pepper to taste.
Carefully add the cooked fettuccine pasta to the skillet, tossing gently to coat the pasta with the creamy pumpkin Alfredo sauce.
Serve immediately, garnished with freshly chopped parsley if desired. Enjoy the warmth of fall in every bite!
Notes
