In a large pot of boiling salted water, add the fettuccine and cook according to package instructions until al dente. Drain and set aside, reserving 1/2 cup of the pasta water.
In a large skillet, heat the olive oil over medium heat. Add the pumpkin puree and cook for about 2 minutes to warm it through.
Lower the heat and slowly stir in the heavy cream, mixing until well combined. Gradually add the Parmesan cheese, stirring constantly until melted and the sauce becomes creamy.
Sprinkle in the garlic powder, nutmeg, black pepper, and salt. Adjust seasoning to taste.
Add the cooked fettuccine to the skillet with the pumpkin Alfredo sauce. Toss gently to coat the pasta evenly. If the sauce is too thick, add a splash of the reserved pasta water until you reach the desired consistency.
Divide the creamy pumpkin Alfredo pasta into serving bowls and garnish with freshly chopped parsley.
Notes
Serve in deep bowls with an extra sprinkle of Parmesan and a drizzle of olive oil on top for an elegant touch.
