Preheat the oven to 350°F (180°C). Prepare the recipe as instructed. Transfer everything to a baking dish greased with olive oil or butter, add breadcrumbs for a crunchy topping, dot with a bit of butter, and bake for 20-25 minutes until bubbly and golden brown. Or make Old-Fashioned Baked Mac and Cheese or Macaroni with Cream Cheese.
