How to Make Mexican White Trash Casserole Recipe
Step 1: Cook the Beef and Onion
Start by preheating your oven to 350°F (175°C) to get things ready to bake. While that’s warming up, in a skillet over medium heat, cook the ground beef and chopped onion until the beef is fully browned and no pink remains. This step develops the rich, savory base flavor that sets the tone for the whole casserole. Be sure to drain excess fat to keep the dish from getting greasy.
Step 2: Add Seasoning and Simmer
Once the beef and onion are perfectly cooked, stir in the taco seasoning packet along with 1/4 cup water. Let this mixture simmer for 2 to 3 minutes, allowing the flavors to meld and the sauce to thicken slightly. This is where the Tex-Mex magic happens!
Step 3: Combine the Creamy Ingredients
Remove the skillet from heat, then fold in the diced tomatoes with green chilies, cream of chicken soup, sour cream, and half of the shredded cheddar cheese. Stir thoroughly until everything is beautifully combined into a creamy, cheesy mixture that will make your mouth water.
Step 4: Assemble the Casserole Layers
Grease a 9×13-inch baking dish to prevent sticking. Spread half of the crushed tortilla chips evenly across the bottom. Then, spoon the beef mixture over the chips, spreading it out gently but evenly to cover the base layer.
Step 5: Top and Bake
Sprinkle the remaining shredded cheddar cheese over the beef layer, then cover with the rest of the crushed tortilla chips. Pop the casserole into the oven and bake uncovered for 25 to 30 minutes, or until the casserole is bubbling and the top is beautifully golden and crispy. Let it rest for 5 minutes after baking to let the layers settle before serving.
How to Serve Mexican White Trash Casserole Recipe

Garnishes
Garnishing really elevates this dish beyond simple comfort food. Try sprinkling chopped green onions for a pop of color and freshness, or add thin slices of jalapeños for that spicy kick that wakes up your taste buds. These options help balance the richness and add a vibrant, fresh finish.
Side Dishes
This casserole is hearty enough to stand alone, but it also pairs wonderfully with a crisp green salad or a side of Mexican rice. Chips and salsa or guacamole are classic companions that bring a cool vibe alongside the warm casserole. For something extra special, a dollop of sour cream on the side complements the spicy, cheesy layers perfectly.
Creative Ways to Present
Want to impress your guests? Serve individual portions in small ramekins or build it into layered Mexican casserole cups for easy handheld bites at parties. Another fun idea is to place the casserole alongside a taco bar spread so everyone can customize their plate with their favorite toppings and sides.
Make Ahead and Storage
Storing Leftovers
Leftover Mexican White Trash Casserole Recipe keeps beautifully in the refrigerator for up to 3 days. Store it in an airtight container to maintain moisture and prevent the chips from getting soggy. It makes a fantastic next-day meal that tastes almost as good as freshly baked.
Freezing
You can freeze this casserole for longer storage. Prepare and bake as directed, then allow it to cool completely before wrapping tightly in plastic wrap and aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months, allowing you to enjoy this delicious recipe anytime.
Reheating
To reheat, thaw in the refrigerator overnight if frozen. Warm individual portions in the microwave or reheat the whole casserole in a 350°F oven covered with foil until heated through (about 20 minutes). Remove the foil during the last few minutes for that crispy top to come back to life.
FAQs
Can I substitute the ground beef with another protein?
Absolutely! The Mexican White Trash Casserole Recipe is super flexible. You can use ground turkey, shredded chicken, or even go vegetarian by swapping the meat for extra beans and vegetables.
Is it possible to make this casserole gluten-free?
Yes, just make sure to use gluten-free taco seasoning and gluten-free tortilla chips. This way, you keep all the flavor and textures without worrying about gluten.
Can I add more vegetables to this casserole?
Definitely! Chopped bell peppers, olives, or corn are great additions that add extra color, crunch, and nutrition. Just stir them into the beef mixture before assembling.
How spicy is this casserole? Can I adjust it?
The heat level is moderate thanks to the green chilies and optional jalapeños, but you can easily adjust by omitting jalapeños or adding more if you love spice. The taco seasoning usually has some mild heat, so feel free to tweak according to your taste.
What is the best way to keep the tortilla chips crunchy?
The trick is layering chips at both the bottom and on top. Baking uncovered helps keep the top layer crisp, while the creamy beef mixture softens only the chips just beneath it, creating a delightful contrast of textures.
