Simply Recipes

Casseroles can be family recipes that have been made for generations or modern recreations of classics meant to save you time in the kitchen. Regardless of the ingredients, a casserole is a recipe that includes a combination of vegetables, sauces, and often cheeses that are stirred together and baked creating an easy side dish. Sometimes they go by the name of casserole, but these recipes can be called bakes and gratins, too.

Whether they are gifted to the new neighbors who just moved in, served with family at the holidays, or presented to friends at a potluck, casseroles were meant to be shared. Most casserole recipes make enough to feed eight or more people and many can be made ahead and refrigerated or frozen before baking.

Some casseroles focus more on the vegetables in an effort to offer a healthier option while others are downright indulgent to create the ultimate comfort food. This list of casserole side dishes gives you a little bit of everything for recipe ideas you can serve among family and friends all year long.
