21 Crazy Easy Gluten-Free Casseroles

Casseroles are the ultimate weeknight savior, but when you are adhering to a gluten-free diet, the standard “dump-and-bake” recipes often fall short. Most traditional casseroles rely heavily on condensed canned soups (which almost always contain wheat flour as a thickener), regular pasta, and breadcrumb toppings.

However, adapting casseroles to be completely gluten-free does not mean sacrificing convenience. By utilizing naturally gluten-free bases like quinoa, rice, corn tortillas, and potatoes—alongside certified gluten-free pastas and cream soups—you can create the exact same comforting, hands-off meals without any of the dietary distress.

The secret to a “crazy easy” casserole is minimizing the amount of cooking required before the dish goes into the oven. These recipes rely on pre-cooked proteins (like rotisserie chicken or smoked sausage), frozen vegetables, and simple sauces that mix together right in the baking dish.

Here are 21 crazy easy, completely gluten-free casseroles that will save your weeknights.
