How to Make Mexican White Trash Casserole Recipe
Step 1: Brown the Beef and Onions
Begin by preheating your oven to 350°F (175°C). In a large skillet over medium heat, cook the ground beef together with the diced onion. Stir frequently as the beef browns and the onions soften, about 6 to 8 minutes. Once fully cooked, drain any excess grease to keep the casserole from becoming too oily.
Step 2: Season and Combine the Ingredients
Next, stir the garlic powder, chili powder, cumin, and black pepper into the beef mixture for that fabulous Tex-Mex flavor punch. Then, pour in the Rotel tomatoes with their juices, the cream of chicken soup, and sour cream. Mix everything thoroughly until you have a creamy, flavorful filling. Finally, fold in 1 cup of the shredded cheddar cheese to add richness and cheesy goodness to the mix.
Step 3: Layer the Casserole
Grease a 9×13-inch baking dish to prevent sticking. Spread half of the crushed tortilla chips in an even layer at the bottom. Carefully spoon and spread the beef and cheese mixture over the chips, creating an even layer. Top this with the remaining crushed tortilla chips and sprinkle the last 1/2 cup of cheddar cheese evenly on top. This layering is what creates the perfect balance of crunchy and melty textures that make this casserole irresistible.
Step 4: Bake to Perfection
Place the casserole in your preheated oven and bake uncovered for 25 to 30 minutes. Look for bubbling edges and golden cheese on top— that’s your cue that the casserole is ready. This baking time allows all the flavors to meld together while ensuring a satisfyingly crispy topping.

Garnishes
To add an extra pop of color and freshness, sprinkle some chopped green onions or cilantro just before serving. These garnishes not only brighten up the look but also add a mild, herbal contrast to the rich casserole, elevating the entire eating experience.

Freezing
You can freeze this Mexican White Trash Casserole Recipe either before baking or after it’s cooled. Wrap it tightly with foil or place it in an airtight container and freeze for up to 2 months. When you’re ready to enjoy it again, thaw overnight in the fridge for best results.

To reheat, bake the casserole at 350°F (175°C) for about 20 minutes or until warmed through. Alternatively, single servings can be reheated in the microwave, but baking helps maintain that delightful crispy topping.
