How to Make Mexican White Trash Casserole
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 350°F. Give a 9×13-inch baking dish a light mist of nonstick spray or a swipe of butter—this makes serving and cleanup a breeze.
Step 2: Cook the Beef and Onion
In a large skillet, combine the ground beef and diced onion over medium heat. Cook until the beef is browned and the onion is soft, stirring occasionally. Once everything is cooked through, drain off any excess grease to keep your casserole from turning out soggy.
Step 3: Add Taco Seasoning and Simmer
Sprinkle the taco seasoning mix over your beef and onion, then pour in the water. Stir well and let the mixture simmer for 3 to 4 minutes. This step ensures all those spices infuse deeply, giving your Mexican White Trash Casserole its irresistible flavor.
Step 4: Mix the Creamy Filling
Grab a large mixing bowl and combine the cream of chicken soup, Rotel, sour cream, shredded cheddar cheese, and drained corn. Stir in your warm beef mixture until everything is thoroughly blended. This is where the magic happens—everything melds together into a creamy, cheesy base.
Step 5: Assemble the Casserole
Spread a generous layer of corn chips or crushed tortilla chips across the bottom of your prepared baking dish. Spoon the beef and cheese mixture evenly over the chips. Top with another handful of chips and, if you’re feeling extra indulgent, a sprinkle of additional cheddar cheese.
Step 6: Bake to Perfection
Slide the casserole into your preheated oven and bake for 25 to 30 minutes, until it’s bubbling around the edges and the cheese is gloriously melted. The aroma alone will have everyone circling the kitchen.
Step 7: Finish with Fresh Garnishes
Once out of the oven, let your Mexican White Trash Casserole rest for a few minutes. Then shower it with chopped green onions and cilantro for a pop of color and freshness. Grab your biggest serving spoon and dig in!
How to Serve Mexican White Trash Casserole

Garnishes
Garnishing is where you can really make your Mexican White Trash Casserole shine. A scattering of freshly chopped green onions and cilantro not only adds color but also a burst of freshness that cuts through the richness. For a spicier touch, toss on some sliced jalapeños or a dollop of salsa. If you love creamy toppings, a spoonful of extra sour cream never hurts.
Side Dishes
This casserole is hearty enough to stand on its own, but pairing it with sides makes for a spectacular meal. A crisp green salad with lime dressing, creamy guacamole, or a simple bowl of black beans all make fantastic partners. For a fun twist, serve with a side of Mexican rice or even a fresh corn salad to echo the flavors inside.
Creative Ways to Present
If you’re hosting friends, try serving Mexican White Trash Casserole in individual ramekins for a personal touch. For potlucks, bake it in a disposable foil pan for easy transport. You can also scoop it into warm tortillas for a Tex-Mex twist on tacos, or layer over nachos for the ultimate party platter.
Make Ahead and Storage
Storing Leftovers
Leftovers of Mexican White Trash Casserole keep beautifully in the fridge. Transfer cooled portions to an airtight container and refrigerate for up to 4 days. The chips will soften a bit, but the flavor only gets better with time.
Freezing
This casserole is a dream for meal prep! Assemble everything (hold off on the final layer of chips for best texture), then wrap tightly and freeze for up to 3 months. When ready to enjoy, thaw overnight in the fridge, add the chips on top, and bake as directed.
Reheating
To reheat, cover the casserole with foil and warm in a 350°F oven until heated through—about 20 minutes. For a speedy lunch, individual portions can be microwaved for 1-2 minutes. If you like your chips extra crunchy, add a fresh handful just before serving.
FAQs
Can I use ground turkey or chicken instead of beef?
Absolutely! Ground turkey or shredded rotisserie chicken are fantastic swaps that lighten things up without sacrificing flavor. Just cook as you would the beef, and proceed with the recipe.
What’s the best way to make this casserole spicier?
To kick up the heat, use hot Rotel, add diced jalapeños to the filling, or sprinkle some crushed red pepper flakes. You can also add a layer of sliced pickled jalapeños on top before baking.
Can I make Mexican White Trash Casserole ahead of time?
Definitely! Assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. When ready, bake as directed, adding a few extra minutes if it’s coming straight from the fridge.
What kind of chips work best?
Both corn chips and crushed tortilla chips work great. Corn chips give a heartier crunch, while tortilla chips add a lighter, crispier bite. Try both and see which your family prefers!
How do I make this casserole gluten-free?
To make a gluten-free version of Mexican White Trash Casserole, use a gluten-free cream of chicken soup (or make your own), and double-check that your taco seasoning and chips are labeled gluten-free.
