Creating this Pumpkin Pasta Sauce is a straightforward process. Just follow these simple steps:

1. Cook the Pasta: Begin by cooking your choice of pasta according to package instructions in salted water. Drain and set aside, reserving some pasta water.
2. Sauté the Onions: In a large skillet, heat olive oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes.
3. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant, being careful not to burn it.
4. Combine Ingredients: Add the pumpkin puree, heavy cream, vegetable broth, dried sage, dried thyme, salt, and black pepper to the skillet. Stir well to combine.
5. Simmer the Sauce: Allow the sauce to simmer on low heat for about 10 minutes, stirring occasionally. This allows the flavors to meld beautifully.
6. Incorporate Cheese: Stir in the grated Parmesan cheese until melted and well incorporated into the sauce. Adjust seasoning to taste.
7. Mix with Pasta: Toss the cooked pasta into the sauce, ensuring the noodles are evenly coated. If the sauce is too thick, add reserved pasta water a little at a time to reach your desired consistency.
8. Serve Immediately: Once everything is well combined and heated through, remove from heat and prepare for serving.

These steps will guide you through the process of making this incredible Pumpkin Pasta Sauce effortlessly.
