In a large skillet or pot, heat the olive oil over medium heat. Add the minced garlic and cook until fragrant, about 1 minute.
Stir in the pumpkin puree, heavy cream, vegetable broth, dried sage, salt, and pepper. Bring to a simmer.
Add the pasta to the simmering sauce and cook according to package directions, or until al dente, stirring occasionally. The sauce will thicken as the pasta cooks.
Once the pasta is cooked, stir in the grated Parmesan cheese until melted and well combined.
Serve immediately. Garnish with extra Parmesan cheese or fresh sage if desired.
Notes
This recipe is easily adaptable. You can add sautéed mushrooms or spinach for extra vegetables. For a spicier kick, add a pinch of red pepper flakes.
