1 cup corn kernels (canned, drained, or frozen)
1 cup salsa
2 cups shredded Mexican cheese blend, divided
1 cup sour cream
8 small flour tortillas, cut into wedges

Instructions
Preheat the oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
Cook the beef mixture
Heat olive oil in a large skillet over medium heat.
Add the chopped onion and cook for 2–3 minutes until softened.
Stir in the garlic and cook for 30 seconds until fragrant.
Add the ground beef and cook until browned, breaking it apart as it cooks. Drain any excess grease.
Season the filling
Sprinkle in the taco seasoning and pour in the water.
Stir well and simmer for 2 minutes.
Add the black beans, corn, and salsa. Mix until combined and heated through.
Season with salt and black pepper to taste.
Assemble the casserole
Spread a thin layer of the beef mixture in the prepared baking dish.
Arrange half of the tortilla wedges over the beef.
Spread half of the remaining beef mixture on top.
Dollop half of the sour cream over the layer.
Sprinkle with 1 cup of shredded cheese.
Repeat the layers with the remaining tortillas, beef mixture, sour cream, and cheese.
Bake
Cover with foil and bake for 20 minutes.
Remove the foil and bake for an additional 10–15 minutes, or until the cheese is melted, bubbly, and lightly golden.
Garnish and serve
Let the casserole rest for 5 minutes before serving.
Top with fresh cilantro, green onions, diced tomatoes, and jalapeños if desired.
