Mexican White Trash Casserole is the kind of soul-warming, fuss-free comfort food you crave after a long day. It layers chips, seasoned beef, creamy beans, and gooey cheese into a super satisfying bake that is pure weeknight joy. I love how it takes all the flavors of a great taco night and transforms them into something bubbly and irresistible from the oven—the ultimate crowd-pleaser at potlucks or game nights.
I whipped this up the first time when the pantry was running low before payday and everyone was hooked—the crushed chips on the bottom create the best crispy base, and the cheesy top is always the first thing to disappear.
Ingredients
- Tortilla chips: They form the crunchy bottom layer—grab a sturdy style so they hold up under the fillings
- Ground beef or turkey: Either one works well—look for lean ground beef or turkey for less grease but all the flavor
- Taco seasoning: This adds all of the signature spices—use your favorite brand or mix your own if you like less salt
- Salsa: Choose a heat level that suits your family, and pick one with real tomatoes and visible veggies for great flavor
- Refried beans: The creamy texture binds the whole casserole together—look for ones with minimal added fat and real pinto beans
- Shredded Mexican blend cheese: Melts beautifully and brings all the layers together—pre-shredded is easy, but fresh-shredded always tastes even better
- Toppings like sour cream, guacamole, tomatoes, black olives, green onions, and cilantro: Add brightness and freshness at the end—choose ones your family loves or let everyone top their own
Step-by-Step Instructions
- Prepare Your Baking Dish:
- Spray or butter your 9x13-inch pan thoroughly to make sure the finished casserole comes out easily and nothing sticks to the bottom.
- Brown the Meat and Add Seasoning:
- Set a large skillet over medium heat and break up your ground beef or turkey. Stir it often and let it brown fully until no pink remains which should take 6 to 8 minutes. Drain away the extra grease to keep things from getting soggy. Sprinkle over the taco seasoning then pour in the salsa and stir well making sure all the meat is coated with flavor. Let this simmer gently for a few minutes so everything tastes unified.
- Layer the Bottom with Chips:
- Evenly scatter half of your crushed tortilla chips into the prepared baking dish pressing lightly to cover the bottom.
- Add a Creamy Bean Layer:
- Spoon refried beans over the chips and gently spread them out using the back of a spoon making sure to cover all the chips. This will help hold the chips together once you slice it.
- Add the First Meat and Cheese Layer:
- Pile on half of your seasoned meat mixture over the beans spreading it into an even layer. Then scatter one cup of cheese over the top letting it fall into the corners and edges.
- Repeat Chips and Layers:
- Add the rest of your chips on top next pressing them in slightly so they nestle in. Layer over the remaining beef mixture then scatter on the rest of the shredded cheese for a gooey finish.
- Bake Until Golden and Bubbly:
- Slide the casserole into your preheated oven and bake for 20 to 25 minutes. You want to see the cheese completely melted and bubbling gently around the edges for best flavor and texture. Let it cool for about five minutes out of the oven so the layers settle and you can scoop it easily.
- Add Fresh Toppings and Serve:
- Finish with your choice of fresh toppings like dollops of sour cream a handful of chopped tomatoes olives green onions and cilantro. Serve right away while the cheese is still gloriously gooey.

The salsa makes all the difference here. I have a soft spot for fire-roasted varieties—they give the whole dish a smoky depth that reminds me of family taco nights growing up. There is something about the way fresh cilantro on top brightens everything and brings back lazy summer memories by the patio.
Storage Tips
Cool leftovers completely then store in an airtight container in the fridge for three days. For longer keeping, pack portions tightly and freeze for up to two months. When reheating, cover with foil and bake at 350 degrees until hot throughout adding a sprinkle of fresh cheese if you want to perk it up.
Ingredient Substitutions
Try shredded rotisserie chicken instead of beef for a quick and easy swap. Vegetarian friends will love it with black beans and roasted corn instead of meat—just make sure your refried beans do not contain lard. If you like a little more heat, swap in pepper jack for some of the cheese.
Serving Suggestions
Pair big scoops with a fresh green salad and a wedge of lime for brightness. For a party, set out bowls of toppings so everyone can customize their own plate. Sometimes I crumble a few fresh chips over the top just before serving for a little extra crunch.
