Lasagna is a much-loved baked pasta dish that has spread from Italy and throughout the world, and while everyone has their own way of preparing it, there are a few procedural standards that cooks should always follow for best results. One of these rules is to always cover your lasagna before popping it in the oven.

Most lasagnas need to be cooked for at least 30 minutes at at least 375 degrees Fahrenheit, and if left uncovered, heat exposure will quickly dry out the entire dish. By putting a layer of tin foil over your baking dish, moisture will get trapped inside while still allowing it to cook properly, making sure it won't turn out dry.

For a proper bubbly, crispy top, put your lasagna under the broiler with no cover for just a few minutes at the end of cooking. Simply take the foil off of your baking dish, change your oven to the broiler setting, and keep a close eye on the lasagna until it looks done, rather than keeping it uncovered the whole time.
