Pasta Bake Cook 2 cups pasta. Combine with 3-4 cups smoked homemade spaghetti sauce. Place in a baking dish. Top with 1 cup shredded mozzarella cheese and 1/4 cup grated parmesan cheese. Bake on the pellet grill at 350F for 20-25 minutes, until the cheese bubbles and browns. Place a loaf of garlic bread on the grill during your last 5 minutes of cooking to heat.
