In the skillet with the beef mixture, add the black beans, corn, diced tomatoes with green chilies, and enchilada sauce. Stir well to combine, letting the flavors meld together.
If you want a heartier casserole, stir in the cooked rice at this stage. It adds great texture and can help stretch the dish for larger servings.
Step 4: Layer the Casserole
In the prepared casserole dish, place a layer of corn tortillas or a handful of tortilla chips at the bottom to create a base.
Spoon half of the beef mixture over the tortillas or chips, spreading it evenly.
Sprinkle one cup of the shredded cheese over the beef layer.
Add another layer of tortillas or chips on top of the cheese.
Spread the remaining beef mixture over this second layer, then top with the rest of the shredded cheese.
Step 5: Bake and Serve
Cover the casserole with aluminum foil and bake in the preheated oven for about 20 minutes.
Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
Allow the casserole to cool for a few minutes before serving.
Step 6: Garnish and Enjoy
Top with your favorite garnishes like chopped cilantro, sliced green onions, diced tomatoes, sour cream, or a few slices of avocado.
Serve warm, scooping portions onto plates or into bowls. This dish pairs wonderfully with a side of Mexican rice, guacamole, or a simple green salad.
