This recipe is a healthier version of the classic Alfredo pasta dish. Roast the spaghetti squash in the oven and set aside. In a pan, melt butter and sauté minced garlic until fragrant. Add heavy cream and grated Parmesan cheese, and stir until the cheese is melted and the sauce is thickened. Add the cooked spaghetti squash to the pan with the sauce and stir until the squash is coated. Serve with additional Parmesan cheese and chopped parsley.
