Good news for gluten-free eaters: making this casserole gluten-free is super easy! Just make sure to use certified gluten-free corn tortillas and double-check that your enchilada sauce and refried beans are also gluten-free (most are, but it's always smart to check labels). With those small tweaks, you’ll have a gluten-free version that’s just as creamy, flavorful, and satisfying as the original!
