Making One Pot Stove-Top Pumpkin Mac and Cheese is straightforward and simple. Follow these steps to create the perfect dish:

1. Cook Pasta: In a large pot, add the uncooked pasta and vegetable broth. Bring to a boil over medium heat.

2. Stir Occasionally: Stir the pasta occasionally to ensure even cooking and prevent sticking. Cook for about 7-10 minutes or until al dente.

3. Add Pumpkin: Reduce the heat to low and stir in the pumpkin puree, mixing until well combined.

4. Mix in Milk and Cheese: Gradually add the milk while stirring, then mix in the cheddar cheese and Parmesan cheese until melted and creamy.

5. Season: Add the garlic powder, onion powder, dried sage, salt, and black pepper to the pot, stirring well to combine all the ingredients.

6. Simmer: Allow the mixture to simmer on low heat for another 3-5 minutes, stirring continuously until the sauce thickens to your desired consistency.

7. Taste and Adjust: Taste the mac and cheese and adjust the seasoning if necessary, adding more salt or spices as preferred.

8. Serve: Remove from heat and let it sit for a minute before serving for the sauce to thicken slightly.
