Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set it aside.
Heat olive oil in a large skillet over medium heat. Add the diced onion and sauté for 3-4 minutes until softened.
Stir in the minced garlic and cook for 1 minute until fragrant.
Add the ground beef to the skillet and cook until browned, breaking it apart with a spatula. This should take about 5-7 minutes.
Drain any excess grease from the skillet, then stir in the taco seasoning, diced tomatoes with green chilies, black beans, and corn. Let the mixture simmer for 3-5 minutes to combine flavors.
Place two tortillas at the bottom of the greased baking dish, overlapping as needed to cover the base.
Spread one-third of the beef mixture evenly over the tortillas, then sprinkle one-third of the shredded cheese on top.
Repeat the layering process (tortillas, beef mixture, cheese) two more times, finishing with a layer of cheese on top.
Cover the dish with aluminum foil and bake in the preheated oven for 15 minutes.
Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbling.
Let the casserole cool for 5 minutes before slicing and serving. Optional: Top each serving with a dollop of sour cream and a sprinkle of green onions.
