This spicy Mexican casserole has been my family's go-to dinner solution for hectic weeknights for years. It combines layers of zesty ground beef, creamy soups, and crunchy tortilla chips into a comforting dish that never fails to satisfy everyone at the table.
I first created this recipe when hosting an impromptu gathering of my children's friends after soccer practice. The empty dish and requests for the recipe convinced me it needed to become part of our regular rotation.
Ingredients
- Ground beef: Delivers hearty protein and pairs perfectly with Mexican flavors; select 80/20 for best flavor balance
- Onion: Creates an aromatic foundation that sweetens as it cooks; choose firm onions with no soft spots
- Diced tomatoes with green chilies: Rotel adds instant heat and acidity without extra chopping work
- Cream soups: Mushroom and chicken provide rich creaminess and bind all ingredients together
- Corn: Brings sweet pops of texture and color; frozen works fine if you do not have canned
- Black beans: Add fiber and protein; rinse well to remove excess sodium
- Tortilla chips: Create both the crunchy base and topping; thicker restaurant style chips hold up best
- Mexican cheese blend: Melts beautifully and creates that irresistible cheesy pull
- Sour cream: Adds cooling creaminess to balance the spice; full fat creates the best flavor contrast
- Spices: Garlic powder, chili powder, and cumin create the authentic Mexican flavor profile
Step-by-Step Instructions
- Brown the Meat Mixture:
- Cook ground beef and onions over medium heat for about 8 minutes until beef shows no pink and onions become translucent. Take time to break the meat into small crumbles using a wooden spoon. Drain thoroughly to prevent a greasy casserole.
- Create the Flavor Base:
- Add the Rotel tomatoes without draining to capture all the flavorful juices. Stir in both cream soups until completely incorporated with no white streaks remaining. The mixture should look slightly pink from the tomato juice.
- Add Texture Components:
- Fold in the drained corn and rinsed black beans gently to prevent breaking the beans. Sprinkle in all seasonings and adjust salt and pepper to your family's preference. Let the mixture simmer for 2 minutes to marry the flavors.
- Layer the Base:
- Spread half the crushed tortilla chips across the bottom of your greased baking dish creating an even layer. Press them down slightly so they absorb some of the sauce during baking without becoming completely soggy.
- Add the Filling:
- Pour your meat mixture carefully over the chip base making sure to spread it into all corners of the dish. Use a spatula to create an even layer approximately 1 inch thick throughout the entire casserole.
- Top and Bake:
- Sprinkle remaining tortilla chips over the meat layer creating a crunchy top layer. Cover completely with shredded cheese ensuring even coverage. Bake until the edges bubble and cheese turns golden brown about 28 minutes in most ovens.

You Must Know
My absolute favorite ingredient in this recipe is the combination of both cream soups. I discovered this trick from my grandmother who always said mixing the two creates depth that neither can achieve alone. My son always requests this casserole for his birthday dinner which makes it extra special in our family memories.
Make It Your Own
This casserole welcomes customization based on your family's preferences. For a spicier version add diced jalapeños or a teaspoon of cayenne pepper. If serving to children use mild Rotel tomatoes and increase the cheese for a more mellow flavor profile. Vegetarians can substitute the beef with two extra cans of beans or a package of plant-based ground meat alternative for similar texture.
Storage and Reheating
Store leftover casserole covered in the refrigerator for up to 3 days. The flavors actually intensify overnight making it sometimes even better the second day. For reheating cover with foil and warm in a 325°F oven for about 20 minutes until heated through. Microwaving works in a pinch but will make the chips softer. For freezing cover tightly with plastic wrap and foil and freeze for up to 2 months; thaw overnight in the refrigerator before reheating.
Serving Suggestions
Turn this casserole into a complete fiesta by serving with a simple side salad tossed with lime vinaigrette. Set out a toppings bar with extra sour cream, diced avocado, pickled jalapeños, and fresh cilantro allowing everyone to customize their portion. For a refreshing beverage pairing, try homemade horchata or virgin margaritas with salted rims.
