Creating the perfect Pumpkin Mac and Cheese is straightforward. Just follow these easy steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add elbow macaroni and cook according to package directions until al dente. Drain and set aside.
2. Make the Cheese Sauce: In a separate saucepan, melt the butter over medium heat. Add the flour and whisk for about 1-2 minutes until combined.
3. Add Milk: Gradually pour in the milk while constantly whisking to prevent lumps. Continue to cook for approximately 3-4 minutes until the mixture thickens slightly.
4. Incorporate the Pumpkin: Stir in the pumpkin puree, garlic powder, onion powder, nutmeg, salt, and pepper. Mix thoroughly until well combined.
5. Add Cheese: Remove the saucepan from heat. Stir in the sharp cheddar cheese and grated Parmesan cheese until melted and creamy.
6. Combine with Pasta: Fold the cooked macaroni into the cheese sauce, ensuring all pasta is well coated with the creamy mixture.
7. Transfer to Baking Dish: If desired, transfer the mixture to a greased 9×13 inch baking dish for baking. This step is optional.
8. Top with Paprika: If using, sprinkle paprika on top for added flavor and color.
9. Bake (Optional): Preheat the oven to 350°F (175°C) and bake for 15-20 minutes until heated through and slightly golden on top.
10. Serve: Once ready, remove from the oven, allow to cool for a few minutes, and serve warm.

By following these straightforward instructions, you can whip up a remarkable Pumpkin Mac and Cheese that will leave a lasting impression.
