Bring a large pot of salted water to a boil. Cook the penne pasta until it’s al dente, following the package instructions. Before draining, reserve ½ cup of pasta water and set it aside. Drain the remaining water, and set the cooked pasta aside.
1 pound penne pasta, 1 tablespoon olive oil
In a large pot or deep skillet, heat the olive oil over medium-high heat. Add the chopped shallot and sauté for about 2 minutes until softened and translucent. Stir in the minced garlic and fresh rosemary, cooking for about 1 minute until fragrant.

Add the pumpkin puree and vegetable broth to the pot. Stir until the mixture is smooth and well-combined. Reduce the heat to medium and pour in the heavy cream. Season with salt, pepper, and a pinch of nutmeg. Let the sauce simmer for a few minutes to develop the flavors.

Serve the pasta warm, garnished with toasted pumpkin seeds, crispy sage leaves, and extra Parmesan cheese.
