Creating the delightful Creamy Pumpkin Alfredo is straightforward when you follow these simple steps:

1. Cook the Pasta: In a large pot, boil salted water and cook the fettuccine according to package instructions. Drain and set aside.
2. Sauté Garlic: In a large skillet, melt the butter over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.
3. Make the Sauce: Stir in the pumpkin puree and heavy cream, mixing thoroughly until well combined.
4. Add Seasonings: Sprinkle in the nutmeg, cinnamon, salt, and pepper, stirring well to incorporate all flavors.
5. Cheese It Up: Gradually add the grated Parmesan cheese into the skillet, stirring constantly until melted and the sauce is creamy.
6. Combine: Add the cooked fettuccine to the skillet, tossing to coat the pasta evenly in the creamy sauce.
7. Adjust Consistency: If the sauce is too thick, add a little pasta water to reach your desired consistency.
8. Taste and Adjust: Taste the pasta and adjust seasonings if needed.
9. Serve Immediately: Remove from heat and serve warm, garnished with fresh parsley or sage if desired.

These steps will lead you to a bowl of warmth and comfort that defines Creamy Pumpkin Alfredo perfectly.
