Macaroni and cheese can indeed be prepared without baking in the oven. Simply combine the cooked pasta with the sauce and sprinkle with cheese. However, many prefer the baked cheese crust as it adds a rich flavor to the dish.
Keep in mind that ovens can vary, so the temperature and cooking time may differ from the recipe instructions.
To ensure the oven reaches the desired temperature, preheat it in advance (about 10-20 minutes before cooking).
Any heat-resistant baking dish will work for this recipe. If using a silicone mold, there's no need to grease it with butter or margarine. However, it's advisable to lightly grease metal, ceramic, or glass dishes with vegetable oil to prevent the pasta from sticking and burning.
