Cook the pasta according to the package instructions until al dente. Reserve 1 cup of pasta water and drain the rest. Set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant.
Stir in the dried sage and thyme. Cook for another minute to allow the herbs to release their flavor.
Add the pumpkin puree to the skillet and stir to combine with the garlic and herbs. Cook for 3-4 minutes.
Gradually add the reserved pasta water to the skillet, stirring until the sauce reaches your desired thickness.
Stir in the crumbled feta cheese until melted and creamy.
Season the sauce with salt and pepper to taste, adjusting flavors as needed.
Toss the cooked pasta into the skillet, ensuring it is evenly coated with the pumpkin feta sauce.
Serve the pasta immediately, garnished with fresh herbs or Parmesan cheese if desired.
