Ingredients You’ll Need
One of the reasons I can’t get enough of Mexican White Trash Casserole is how accessible and impactful each ingredient is. Every item works double-duty, lending unique taste, texture, or that signature pop of color that makes this dish a weeknight superstar.
- Ground beef: Rich, meaty flavor forms the hearty backbone of this casserole.
- Yellow onion: Adds sweetness and savory depth once sautéed with the beef.
- Taco seasoning: Infuses classic Mexican-inspired zest that wakes up every bite.
- Water: Helps the seasoning bloom and keeps the filling moist and saucy.
- Rotel diced tomatoes with green chilies: Brings tang, brightness, and mild heat to the party.
- Cream of chicken soup: Lends a luscious, savory creaminess you’ll adore.
- Cream of mushroom soup: Adds another layer of velvety richness and comforting flavor.
- Sour cream: Tames the spices and makes the filling extra smooth and decadent.
- Shredded cheddar cheese (divided): Melty, gooey, and golden on top—cheese just makes everything better.
- Doritos (Nacho Cheese or Cool Ranch, crushed): The magic ingredient: bold, crunchy, and so nostalgic! They bring texture and extra flavor you can’t miss.
How to Make Mexican White Trash Casserole
Step 1: Cook the Beef and Onions
Start by preheating your oven to 350°F. In a large skillet over medium heat, toss in the ground beef and diced onions. Cook, breaking up the beef as you go, until every morsel is browned and the onions have softened and turned beautifully translucent. Remember to drain off any excess grease—no one wants a soggy casserole!
Step 2: Add Seasonings and Build Flavor
Sprinkle in the taco seasoning and pour in half a cup of water. Stir thoroughly, simmering the mixture for about two to three minutes. This step helps the seasonings bloom and coat every piece of beef, infusing the dish with that unmistakable taco-shop flavor.
Step 3: Mix in Creamy Goodness
It’s time for some kitchen magic. Add the undrained can of Rotel tomatoes with green chilies, cream of chicken soup, cream of mushroom soup, sour cream, and one cup of shredded cheddar cheese directly into the skillet. Stir until everything is blissfully combined and has heated through. This creamy mixture is what transforms the casserole from basic to absolutely unforgettable.
Step 4: Layer with Crushed Doritos
Grease a 9×13-inch baking dish and spread half of your crushed Doritos right on the bottom. This guarantees that every scoop has that irresistible chip crunch. Pour the hot, melty beef mixture evenly over the chips, spreading it with a spatula. Now, pile on the rest of your crushed Doritos for added crispiness.
Step 5: Finish with Cheese and Bake
Sprinkle the remaining cup of shredded cheddar cheese generously over the top—the more cheese, the better! Bake uncovered for 25 to 30 minutes, or until the cheese is golden and bubbling. Let it sit for about five minutes after baking to set up just enough for easy scooping.
How to Serve Mexican White Trash Casserole

Garnishes
Your Mexican White Trash Casserole instantly looks and tastes even better with simple, vibrant garnishes. Try a shower of fresh chopped cilantro, sliced green onions, or a few rings of jalapeño for heat. A dollop of sour cream on top adds creaminess, while diced avocados bring a cool, buttery touch.
Side Dishes
This casserole is hearty, so I love pairing it with light, zippy sides. Think a crisp tossed salad with lime vinaigrette, tangy pickled onions, or even a batch of fresh pico de gallo. If you want something extra, refried beans or Mexican street corn round out the meal beautifully.
Creative Ways to Present
Elevate your Mexican White Trash Casserole by spooning it into individual ramekins for a dinner party, topping it with crushed hot Cheetos for a fun twist, or serving nacho-style with extra chips on the side. It’s also delicious wedged into soft tortillas as an over-the-top taco filling!
Make Ahead and Storage
Storing Leftovers
Store leftover casserole in an airtight container in the refrigerator, where it’ll keep well for up to four days. The chips will soften a bit over time, but the flavors meld together even more deliciously.
Freezing
Mexican White Trash Casserole freezes like a dream. Simply allow the casserole to cool completely, then wrap it tightly (or use freezer-safe containers). Freeze for up to three months, then thaw overnight in the fridge before reheating.
Reheating
To best revive your casserole, reheat portions in the oven at 350°F until warmed through. For a quick fix, you can microwave single servings, but a few extra minutes in the oven will help refresh the crunch and meltiness you love.
FAQs
Can I use ground turkey or chicken instead of beef?
Absolutely! Ground turkey or shredded rotisserie chicken both work wonderfully in Mexican White Trash Casserole. They offer a slightly lighter profile while soaking up all those great taco flavors.
Which type Main Course
Nacho Cheese is the classic pick and pairs perfectly with the other ingredients, but Cool Ranch fans won’t be disappointed—try both and see which your crowd prefers!
How spicy is this casserole?
The level of heat is mild to moderate, thanks to the Rotel tomatoes with green chilies and taco seasoning. If you’re seeking extra spice, add chopped jalapeños or a spicier seasoning blend.
Can I assemble the casserole ahead of time?
Yes! You can prepare the entire casserole up to the baking step, cover, and refrigerate overnight. Just wait to add the top layer of Doritos and cheese until right before baking to keep them crisp.
Is this casserole good for potlucks or making for a crowd?
It’s the ultimate potluck dish! Mexican White Trash Casserole scales up beautifully, travels well, and is always a hit wherever it goes—don’t be surprised if you go home with an empty pan!
