Casseroles are a favorite for many, and for good reason. Casserole recipes can usually be prepped well in advance, and they combine flavors like nothing else. Whether it's a creamy potato gratin, a hearty lasagna, or a baked oatmeal, casseroles are a treat for cooks and eaters alike. They're perfect for using up leftovers and can be made ahead of time and reheated. Plus, baking in the oven often gives you that deliciously crispy top layer.
