Add the pasta, vegetable broth, pumpkin puree, olive oil, salt, pepper, and nutmeg to a large pot over high heat and stir. Cover and bring to a rolling boil, then turn heat down to medium to simmer.
16 ounces short pasta, 2 tablespoons olive oil, 4 cups vegetable broth, 15 ounces pumpkin puree, ¼ teaspoon salt, ⅛ teaspoon black pepper, ¼ teaspoon nutmeg
Cover and simmer over medium for 13-15 minutes, stirring every 3-5 minutes with a wooden spoon, until pasta is al dente. As you stir, scrape the bottom of the pot to ensure the pasta doesn't stick.
Meanwhile, finely chop the sage. Remove the pasta from heat and add the butter, sage, and Parmesan cheese. Stir to coat, allowing the residual heat to melt the butter.
2 tablespoons unsalted butter, ½ ounce fresh sage, ⅓ cup grated Parmesan cheese
Slowly add the milk to thin out the sauce, about 1 tablespoon at a time until you achieve your desired consistency. You may not need all ½ cup.
½ cup milk
Serve hot with a little extra grated Parmesan and sage for garnish. Enjoy!
