Ingredients Overview (Serves 6–8)

  • 1 pound ground beef or ground turkey
  • 1 packet taco seasoning (or homemade blend)
  • 1 can black beans, drained and rinsed
  • 1 can pinto beans or chili beans, drained
  • 1 can diced tomatoes with green chilies
  • 1 can cream of chicken soup
  • 1 can cream of mushroom soup
  • 1½ cups sour cream
  • 2½ to 3 cups shredded cheddar or Mexican-blend cheese
  • 2 cups crushed tortilla chips
  • Optional toppings: sliced jalapeños, green onions, olives, extra chips

Ingredient Quality and Substitutions

Using freshly shredded cheese rather than pre-shredded varieties improves melt quality and flavor. Ground turkey works well as a lighter alternative to beef, while rotisserie chicken can be used for a shredded version of the casserole.

If you prefer a bit more heat, opt for hot diced tomatoes or add a pinch of cayenne pepper. For a milder version, use plain diced tomatoes instead of those with chilies.

Step-by-Step Preparation Instructions

Begin by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish to prevent sticking and ensure easy serving.

In a large skillet over medium heat, cook the ground meat until fully browned, breaking it up as it cooks. Drain excess fat if necessary. Add taco seasoning and a small amount of water according to the packet instructions, allowing the meat to simmer and absorb the flavors.

Building the Creamy Base

In a large mixing bowl, combine the cream of chicken soup, cream of mushroom soup, and sour cream. Stir until smooth and fully blended. This mixture forms the creamy backbone of the casserole, providing richness and binding all ingredients together.

Add the seasoned meat, beans, and diced tomatoes to the bowl. Stir gently until evenly combined, ensuring every component is coated in the creamy mixture.

Layering for the Best Texture

Spread half of the crushed tortilla chips evenly across the bottom of the prepared casserole dish. This layer adds structure and absorbs some of the moisture, preventing the casserole from becoming too soft.

Spoon half of the meat and cream mixture over the chips, spreading it evenly. Sprinkle a generous layer of shredded cheese on top.

Completing the Assembly

Repeat the layers with the remaining tortilla chips, followed by the rest of the meat mixture. Finish with a thick, even layer of cheese, ensuring full coverage for that signature golden, bubbly topping.

For extra crunch, reserve a small amount of chips to add during the final 10 minutes of baking.

Baking Instructions

Place the casserole uncovered in the preheated oven. Bake for 30–35 minutes, or until the cheese is fully melted, bubbling, and lightly golden around the edges.

Allow the casserole to rest for 10 minutes before serving. This helps the layers set and makes slicing and serving much easier.

Serving Suggestions

Serve Mexican White Trash Casserole warm, directly from the baking dish. It pairs well with a simple green salad, steamed vegetables, or fresh fruit to balance the richness.

You can also serve it with extra tortilla chips on the side for scooping, making it ideal for casual family-style meals.
