A quick and easy meatless casserole featuring layers of creamy sauce, black beans, corn, veggies, and melty cheese, perfect for a comforting weeknight dinner.
Do not overload with tortillas to avoid doughy texture. Let excess moisture from mushrooms evaporate fully to prevent watery casserole. Rest casserole after baking for easier slicing and deeper flavor. If casserole looks dry during baking, spoon extra enchilada sauce on top halfway through cooking.
