1 red bell pepper, diced (optional)
Salt and black pepper to taste

For Assembly

1 tablespoon olive oil for cooking

Fresh cilantro, chopped
Sliced green onions

Equipment Needed

9×13-inch baking dish
Large skillet or sauté pan
Wooden spoon or spatula
Cutting board and sharp knife
Can opener
Measuring cups and spoons
Aluminum foil
Cooking spray or oil for greasing

Step-by-Step Instructions

Preheat oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or oil and set aside.
Cook the meat: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the ground beef and cook for 6-8 minutes, breaking it up with a spoon until browned and no pink remains. Drain excess fat if needed.

Sauté vegetables: Add the chopped onion to the beef and cook for 3-4 minutes until softened. Add minced garlic, cumin, chili powder, and taco seasoning, stirring for 1 minute until fragrant.
Add tomatoes and beans: Stir in the fire-roasted tomatoes, crushed tomatoes, tomato paste, chili beans, black beans, and corn. Mix well to combine all ingredients.
Simmer the filling: Reduce heat to medium-low and simmer for 5-7 minutes, stirring occasionally, until the mixture thickens slightly. If adding spinach or bell peppers, stir them in during the last 2 minutes until wilted. Season with salt and pepper to taste.
Prepare tortillas: While the filling simmers, cut each corn tortilla into 4 equal quarters. You’ll use them to create layers in the casserole.
First layer: Arrange about 8 pieces of cut tortilla (or enough to cover) on the bottom of the prepared baking dish. Spread ⅓ of the beef and bean mixture evenly over the tortillas.
Add cheese layer: Sprinkle ½ cup of shredded cheese over the filling layer.
Second layer: Repeat the layering: add another layer of tortilla pieces, ⅓ of the filling, and ½ cup cheese.
Third layer: Add a final layer of tortilla pieces and the remaining ⅓ of the filling.
Sour cream layer: Spread the sour cream evenly over the top of the casserole. This creates a creamy, tangy layer that balances the spices.
Final cheese topping: Sprinkle the remaining 2 cups of shredded cheese generously over the sour cream layer. This will create a golden, bubbly cheese topping.
Cover and bake: Cover the baking dish with aluminum foil and bake for 20 minutes. This allows the casserole to heat through evenly.
Uncover and brown: Remove the foil and bake for an additional 5-10 minutes until the cheese is melted, bubbly, and lightly golden brown.
Rest before serving: Remove from the oven and let the casserole rest for 5-10 minutes. This helps it set so slices hold together better when serving.
Garnish and serve: Top with fresh cilantro, sliced green onions, diced tomatoes, and any other desired toppings. Serve hot with sour cream, salsa, and guacamole on the side.

Pro Tips for Success

Drain excess liquid – Make sure to drain beans and corn well to prevent a watery casserole
Season the filling well – Taste and adjust salt, pepper, and spices before assembling for maximum flavor
Don’t skip the rest time – Letting the casserole sit for 5-10 minutes after baking helps it slice cleanly without falling apart
Layer evenly – Distribute filling and cheese evenly across each layer for consistent flavor in every bite
Use fresh tortillas – Fresh corn tortillas hold up better than old, dried-out ones
Cover while baking – This prevents the cheese from burning while the inside heats through
Customize heat level – Add jalapeños, hot sauce, or cayenne for more spice; use mild ingredients for kids

Substitutions & Variations

Protein options: Use ground turkey, ground chicken, shredded rotisserie chicken, or make it fully vegetarian with only beans
Tortilla types: Flour tortillas work great instead of corn, though corn tortillas are more traditional and gluten-free
Cheese varieties: Try Monterey Jack, pepper jack, Mexican blend, or a combination of cheddar and mozzarella
Bean options: Use kidney beans, pinto beans, refried beans, or a combination of your favorites
Vegetarian version: Omit meat entirely and add extra beans, mushrooms, zucchini, and bell peppers
Enchilada sauce twist: Replace some of the tomatoes with red or green enchilada sauce for enchilada casserole flavor
Add rice: Mix 1 cup cooked rice into the filling for extra heartiness
Spicy upgrade: Use hot salsa, add diced jalapeños, or use pepper jack cheese
Low-carb option: Replace tortillas with thinly sliced zucchini or omit altogether for a taco skillet-style casserole

FAQ

1. Can I make Mexican Tortilla Casserole ahead of time?

Recipe Notes

Mexican Tortilla Casserole is a brilliant example of Tex-Mex comfort food that brings together the best elements of enchiladas, tacos, and lasagna into one easy-to-make dish. This style of layered casserole became popular in the American Southwest as a convenient way to feed large families with pantry staples and leftover ingredients. The beauty of this recipe lies in its adaptability—you can make it as simple or as elaborate as you like, adjusting vegetables, proteins, and spice levels based on what you have on hand and your family’s preferences. The sour cream layer is a signature element that adds creaminess and helps balance the acidity of the tomatoes and the heat from the spices. Many home cooks prepare this casserole on Sundays for easy weeknight dinners, as it reheats beautifully and actually tastes even better the next day after the flavors have melded together. The vegetarian version is particularly popular because it’s naturally high in protein and fiber from the beans while being budget-friendly and satisfying. This casserole is a staple at potlucks and family gatherings across America because it travels well, serves a crowd, and appeals to a wide range of tastes. The layering technique ensures every bite has the perfect ratio of tortilla, filling, and cheese, making it consistently delicious from first serving to last.
