Ingredients

Use these simple components to create layers of creamy, cheesy goodness:

1 lb ground beef
1 packet taco seasoning
1 (10 oz) can Rotel diced tomatoes with green chilies, undrained
1 (8 oz) package cream cheese, softened
1 cup sour cream
2 cups shredded Mexican blend cheese (divided)
3 cups crushed tortilla chips or Fritos
1 cup canned corn, drained
1 (15 oz) can black beans, rinsed and drained
2 tablespoons olive oil
Salt and pepper, to taste
Optional garnish: chopped cilantro, sliced green onions, jalapeños

Instructions

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Heat olive oil in a large skillet over medium heat. Add ground beef and cook until browned, breaking it up as it cooks. Drain excess grease.
Stir in taco seasoning and Rotel tomatoes (with juices). Simmer for 2–3 minutes until well combined and slightly thickened.
Reduce heat to low and add softened cream cheese to the skillet. Stir until fully melted and creamy.
Mix in sour cream, corn, and black beans. Season lightly with salt and pepper if needed. Remove from heat.
Spread half of the crushed tortilla chips evenly across the bottom of the prepared baking dish.
Spoon the beef mixture over the chips, spreading evenly.
Sprinkle 1 cup of shredded cheese over the beef layer.
Add remaining crushed chips on top, followed by the remaining 1 cup of shredded cheese.
Bake uncovered for 25–30 minutes, or until hot and bubbly with lightly golden cheese.
Let rest for 5 minutes before serving. Garnish as desired and enjoy.

Tips for the Best Mexican White Trash Casserole

Soften the cream cheese first for a smoother, lump-free sauce.
Don’t over-crush the chips—you want some texture for crunch.
Drain beans and corn well to avoid excess moisture.
Let it rest briefly after baking so it slices cleanly.
Use freshly shredded cheese for the best melt and flavor.

Easy Variations to Try

One of the best things about this casserole is how adaptable it is:

Spicy Version:
Add diced jalapeños, hot taco seasoning, or a splash of hot sauce.

Chicken Version:
Swap ground beef for shredded rotisserie chicken or cooked ground chicken.

Vegetarian Version:
Skip the meat and add extra beans, sautéed bell peppers, and onions.

Extra Creamy:
Mix in a can of condensed cream of chicken or mushroom soup.

Low-Carb Option:
Replace tortilla chips with crushed pork rinds or omit them entirely.

Serving Suggestions

Mexican White Trash Casserole is hearty enough to serve on its own, but it pairs beautifully with:

A crisp green salad with lime vinaigrette
Mexican rice or cilantro-lime rice
Simple guacamole and salsa
Steamed veggies for balance

It’s perfect for family dinners, game days, church suppers, and freezer meals. Leftovers reheat well and taste even better the next day.

Make-Ahead and Storage

Make Ahead:
Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Add 5–10 minutes to baking time if chilled.

Freezing:
Freeze before baking for up to 2 months. Thaw overnight in the fridge before baking.

Storage:
Store leftovers in an airtight container in the refrigerator for up to 4 days.
