• 1 packet taco seasoning (store-bought or homemade)
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup frozen corn kernels (or canned, drained)
• 1 can (10 oz) diced tomatoes with green chilies (like Rotel)
• 1 cup shredded cheddar cheese (or Mexican cheese blend)
• 1 cup crushed tortilla chips (for layering)
• Cooking spray (to grease the baking dish)

Optional Toppings:

• Diced avocado or guacamole
• Sour cream or Greek yogurt
• Fresh cilantro, chopped
• Salsa or hot sauce
• Lime wedges, for squeezing

Optional Homemade Taco Seasoning:

• 1 tbsp chili powder
• 1 tsp cumin
• 1 tsp paprika
• 1/2 tsp garlic powder
• 1/2 tsp onion powder
• 1/4 tsp cayenne pepper (optional, for heat)
• 1/2 tsp salt
• 1/4 tsp black pepper

Step-by-Step Instructions

Step 1: Preheat and Prepare

• Preheat your oven to 375°F (190°C).
• Lightly grease a 9×13-inch baking dish with cooking spray.

Step 2: Cook the Meat

• In a large skillet over medium heat, cook the ground beef, breaking it up with a spoon until browned.
• Add the onion and garlic, cooking until softened and fragrant.
• Stir in taco seasoning (store-bought or homemade) and a splash of water. Cook for 2–3 minutes until the seasoning coats the meat evenly.

Step 3: Layer the Casserole

• Spread half of the crushed tortilla chips on the bottom of the prepared baking dish.
• Layer the seasoned meat mixture over the chips.
• Add black beans, corn, and diced tomatoes with chilies, spreading evenly.
• Sprinkle shredded cheese over the top.
• Repeat layers if desired, finishing with a generous layer of cheese on top.

Step 4: Bake

• Bake uncovered for 20–25 minutes, until the cheese is melted and bubbly.
• Optional: Broil for 1–2 minutes to get a golden, crispy cheese topping.

Step 5: Serve

• Remove from the oven and let it rest for 5 minutes.
• Top with avocado, sour cream, cilantro, salsa, or a squeeze of lime before serving.

Tips for the Perfect Mexican Casserole

• Crunch Factor: Keep some tortilla chips aside to sprinkle on top before serving for extra texture.
• Protein Options: Swap ground beef for turkey, chicken, or even a plant-based meat alternative.
• Spice Level: Adjust the cayenne or add chopped jalapeños for more heat.
• Make Ahead: Assemble the casserole a few hours in advance and refrigerate until ready to bake.
