Preheat the oven to 350°F (175°C).
In a large skillet over medium heat, cook the ground beef until browned, breaking it apart with a spatula.
Add the chopped onion and minced garlic to the skillet, cooking until the onion is translucent.
Stir in the cumin and chili powder, cooking for an additional minute until fragrant.
Mix in the black beans, corn, and red enchilada sauce, heating through for about 5 minutes.
Layer half of the tortilla strips in the bottom of a greased 9x13-inch baking dish.
Spread half of the beef mixture over the tortilla layer, followed by a sprinkle of cheese.
Repeat the layering process with the remaining tortilla strips, beef mixture, and cheese.
Cover the dish with foil and bake in the preheated oven for 20 minutes.
Remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden.
Let the casserole cool for 5-10 minutes before serving.
