In this filling keto recipe, baked spaghetti squash halves are filled with a vegetable-heavy sauce and topped with a sprinkle of parmesan for a lasagna taste without the carbs. If you love cheese like us, melt grated mozzarella on top along with the parmesan, or add a scoop of full-fat ricotta after baking. For more protein, add ground beef or sausage to the filling.
