Step-by-Step Instructions

Follow these easy steps to make your Mexican White Trash Casserole a guaranteed hit:

Preheat your oven to 350°F (175°C). Grease a 9×13″ baking dish.
Brown the meat: In a large skillet over medium heat, cook 1 lb of ground beef (or turkey/chicken) until fully browned. Drain the grease.
Combine the filling: Add 1 packet taco seasoning, 1 can of Rotel, 1 cup of corn, and 1 can of cream soup. Stir to combine and let it simmer for 5 minutes.
Add dairy: Remove from heat. Stir in 1 cup of sour cream and 1 cup of shredded cheese.
Layer the casserole:
- Begin with a layer of crushed Doritos or tortilla chips
- Spread half the meat mixture
- Add another layer of chips

- Top with remaining meat mixture and the rest of the cheese
Bake uncovered for 25–30 minutes until the cheese is melted and the edges are bubbly.
Let it rest for 5–10 minutes before serving. This helps the casserole set and makes it easier to serve without falling apart.

How to Serve Mexican White Trash Casserole

Serving this Tex-Mex casserole is all about enhancing its bold flavors while keeping things simple.

Top with fresh cilantro, chopped green onions, or sliced avocado for a pop of color and freshness
Pair with a light side salad, Mexican rice, or refried beans
It’s perfect for football watch parties, potlucks, or cozy family dinners
For extra flavor, drizzle with salsa, sour cream, or jalapeño ranch

It’s a flexible dish—serve it straight from the baking dish or portion it out into squares for a more elegant presentation.

Tips for Success

To make sure your casserole comes out perfectly baked and flavorful, keep these tips in mind:

Don’t overdo the chips: too many layers can make it mushy. Stick to one or two for the perfect balance of crunch and creaminess
Use freshly grated cheese instead of pre-shredded for smoother melting
Let it rest for 5–10 minutes before serving to keep it from falling apart

These small adjustments can make a big difference in both texture and flavor.

Variations to Try

This easy casserole recipe is super adaptable. Try switching it up with these fun variations:

Chicken Enchilada Version: Replace beef with shredded chicken and use red or green enchilada sauce
Breakfast Bake: Add scrambled eggs, cooked sausage, and breakfast potatoes
Vegetarian Twist: Omit meat and load up on black beans, corn, bell peppers, and zucchini
Crockpot Version: Layer ingredients in a slow cooker and cook on low for 4–5 hours. Add cheese at the end

Each version still delivers that rich, cheesy Tex-Mex flavor—just with a new spin.

Make-Ahead, Storage, and Reheating

This casserole is meal-prep-friendly and stores well:

Refrigeration:
