This Mexican White Trash Casserole has been a go-to for casual gatherings and busy weeknights when I want something flavorful and satisfying without fuss. It layers familiar Tex-Mex favorites into one easy bake that always disappears quickly around my table.

I first tried it during a weekend get-together and now the whole family asks for it whenever we crave something cozy and spicy.

Ingredients

  • Tortilla chips: lightly crushed to add a crunchy base that holds up well when baked
  • Ground beef or turkey: for a hearty protein layer turkey is a great leaner choice
  • Taco seasoning: to give the beef that classic bold Mexican spice flavor
  • Salsa: adds moisture and a punch of bright tomato and chili notes pick your favorite heat level
  • Refried beans: bring creamy texture and help everything stick together
  • Shredded Mexican blend cheese: melts beautifully and adds gooey richness on top and inside
  • Optional toppings: such as sour cream guacamole diced tomatoes olives green onions and cilantro add freshness and contrast to the rich casserole

Step-by-Step Instructions

Preheat the Oven:
Set the oven to 375 degrees Fahrenheit and lightly grease a 9 by 13 inch baking dish with butter or cooking spray to prevent sticking.
Cook the Meat:
Brown the ground beef in a large skillet over medium heat until no longer pink about 6 to 8 minutes. Drain any fat then stir in taco seasoning and salsa. Let this simmer for 2 to 3 minutes so the flavors blend well.
Build the Casserole Base:
Spread half of the crushed tortilla chips evenly over the bottom of the prepared dish. These chips create a crunchy foundation for the layers above.
Add the Bean Layer:
Spoon the refried beans on top of the chips and spread it into an even creamy layer that helps bind the casserole.
Layer the Beef:
Add half of the seasoned beef mixture on top of the beans spreading it out evenly.
Cheese It Up:
Sprinkle 1 cup of shredded Mexican cheese blend over the beef. This cheese layer is essential for melting and holding the casserole together.
Repeat Layers:
Add the remaining tortilla chips then top with the rest of the beef mixture. Cover with the last cup of cheese ensuring the whole surface is coated for a golden baked finish.
Bake and Rest:
Bake uncovered for 20 to 25 minutes until the cheese is melted bubbling and lightly golden at the edges. Let the casserole cool for about 5 minutes before adding your preferred toppings.

Storage Tips

Store leftovers covered in the refrigerator for up to three days. To reheat cover with foil and warm in the oven to keep the cheese from drying out or microwave in shorter intervals stirring if possible to heat evenly.

Ingredient Substitutions

Swap ground turkey for beef for a leaner meal ground chicken also works well. Use canned black beans instead of refried beans for a chunkier texture if you prefer. If you have a favorite salsa verde or chipotle salsa try those instead of regular salsa to change up the flavor profile. Cheese varieties like Monterey Jack or cheddar can be used if you do not have a Mexican blend on hand.

Serving Suggestions

Top with dollops of sour cream and guacamole for creamy fresh contrast. Add chopped fresh tomatoes and sliced black olives to brighten the dish. Finish with fresh cilantro and chopped green onions for an herbaceous kick. Serve alongside a simple green salad or Mexican rice to round out the meal.
