Casseroles are open containers, and usually open containers will not freeze and crack. If the lid is necessary, the soup should not be filled too full, so that the container will not be broken because of the volume change of the soup at different temperatures during freezing (of course, it is best not to use a container that is too thin and fragile, because the density of water is higher than that of ice, and the volume will naturally increase after freezing). If you take it out, it may break if you heat it immediately.

Casserole is just a container with stable temperature performance and good cold and hot adaptability. If it is washed and dried, it can of course be put in the fresh-keeping area of the refrigerator, and it is also suitable for any room.
