How To Make Tex Mex Casserole

1. Prep work: Preheat the oven to 350°F (180°C) and grease a 9x13-inch casserole dish with nonstick cooking spray.

2. Cook the ground beef: Heat a large nonstick skillet with 1 tablespoon of olive oil over medium heat. Add the ground beef and cook, breaking it apart, until the meat is no longer pink. Season to taste with salt and pepper and mix. When the ground beef has finished cooking, set it aside.

3. Cook the veggies: Add the diced onion, garlic, and red bell pepper to the same skillet. Cook for about 5 minutes, stirring frequently, until the veggies soften.

4. Assemble the casserole: Transfer the meat mixture and veggies to the prepared casserole dish. Add the corn, black beans, and diced tomatoes to the beef mixture and stir to combine. Then add the corn tortillas on top of the casserole.

5. Bake and serve: Bake the casserole for 15 minutes. After 15 minutes, add the shredded cheese on top and bake for another 15 minutes or until the cheese melts. Serve warm with sour cream or anything you want, and enjoy!

Tips To Make The Best Recipe

• Use an oven safe skillet instead of a baking dish for a one dish recipe.
• Use other types of cheese like sharp cheddar cheese, Monterey jack cheese, or mozzarella cheese to switch up the flavor.
• Make Mexican chicken casserole by swapping ground beef for shredded rotisserie chicken.
• Experiment with adding ingredients to the casserole, like chili powder, green bell peppers, jalapenos, or green chiles, for a spicy kick.
• Make this casserole vegetarian by swapping ground beef for pinto beans or extra black beans. Or you can also add rice to make a vegetarian Mexican rice casserole.
• Top the finished casserole with your favorite toppings, like sour cream, sliced avocado, sliced black olives, fresh cilantro, or pickled jalapeños.
• Drizzle enchilada sauce or this Taco Bell nacho cheese on top of the Mexican nachos for even more flavor.

How To Store Tex Mex Casserole

In the fridge: You can store the leftover ground beef casserole mixture in an airtight container and keep it in the fridge for 3-4 days. You'll want to store it separately from the chips since the corn tortillas will get soggy.

In the freezer: Allow the leftover tex mex casserole to cool completely, then transfer to a freezer-safe container and freeze for up to 3 months.

Reheating: The best way to reheat the casserole is to put the ground beef mixture back in a casserole dish topped with the tortilla chips and cheese. Warm it at 350°F for about 10-15 minutes or until the cheese melts again and the casserole is warmed through. Let the frozen beef mixture thaw in the fridge overnight before reheating.
