How To Make Mexican Ground Beef Casserole

1. Prep work: Preheat the oven to 350°F (175°C) and grease a 9x13-inch casserole dish with nonstick cooking spray. Heat a large skillet over medium high heat. When the skillet is hot, add the ground beef and cook until the beef is browned. Once it's fully cooked, set it aside.

2. Cook the peppers: To the skillet, add the olive oil and fry the bell peppers for about 5 minutes in the hot oil.

3. Combine the filling: Return the cooked ground beef to the skillet and add the corn kernels, salsa, and taco seasoning. Stir to combine the ground beef mixture together.

4. Assemble the casserole: Layer 2 flour tortillas on the bottom of the prepared baking dish. Top the tortillas with ⅓ of the beef mixture, enchilada sauce, and Mexican cheese blend. Repeat this until you've used all of the meat mixture, making sure to finish with shredded cheese on top.

5. Bake: Cover the casserole dish with foil and bake for 30 minutes, then remove the foil and bake for another 10 minutes. Let the casserole sit at room temperature for 10 minutes before garnishing and serving with your favorite taco fixings like sour cream. Enjoy!

Tips To Make The Best Recipe

• Substitute the ground beef for ground turkey, ground pork, or shredded chicken, or use black beans, pinto beans, or refried beans instead to make it a vegetarian casserole.
• Top the casserole with crushed tortilla chips for a crispy topping.
• Use corn tortillas for a different texture and flavor.
• Fry the corn tortillas or flour tortillas in a hot skillet before adding to the casserole dish.
• Garnish the casserole with fresh cilantro or green onions for a pop of color.
• Serve Mexican casserole with your favorite taco toppings, like sliced avocado, sour cream, shredded lettuce, or this Taco Bell cheese sauce drizzled on top for more flavor.
• Use shredded cheddar cheese instead of a Mexican cheese blend for a different flavor.
