Yes, sure thing! Prepare the dish all the way up through combining the spaghetti and meat sauce and transferring it to your casserole dish. Cover it well and store it in the fridge overnight. The next day, remove it from the fridge and allow it to sit on the counter for at least 30 minutes. Add the cheese on top and bake in the oven as directed. You may need to extend the cooking time by 15 minutes since the ingredients are cold.
