Ingredient Notes
Shop your pantry: Here’s what builds big flavor in this Mexican trash casserole without overcomplicating your night.
- Ground meat: Beef for classic flavor; turkey or chicken for lighter. Leftover rotisserie chicken works too.
- Aromatics: Onion and garlic to anchor the seasoning—homemade taco spice or a packet both work.
- Rotel tomatoes: Diced tomatoes with green chiles for zesty lift; fire-roasted for smoky depth.
- Beans + corn: Black beans or pinto beans; frozen or canned corn adds sweet crunch.
- Creamy element: Cream of chicken/mushroom soup, or a quick stovetop sour cream + cream cheese sauce.
- Chips or tortillas: Nacho cheese Doritos = OG; tortilla chips or corn tortillas for a sturdier layer.
- Cheese: Shredded Mexican blend, cheddar, pepper jack, or queso blanco for ultimate melt.
- Extras: Pickled jalapeños, cilantro, green onions, lime, and salsa for serving.
- Heat control: Chipotle powder or diced jalapeños for spice; keep it mild for kid-friendly taco casserole.
How To Make Mexican White Trash Casserole Recipe
Layer like a pro: Follow these quick steps for a creamy center and crisp top—exactly what a cheesy Dorito casserole dreams of being.
- Preheat the oven: Set to 375°F (190°C). Grease a 9×13-inch dish for easy serving and cleanup.
- Brown the meat: Cook ground beef in a skillet until crumbled and browned. Drain excess fat.
- Sauté aromatics: Add onion and garlic; cook until softened and fragrant, about 2–3 minutes.
- Bloom spices: Stir in taco seasoning (or chili powder, cumin, paprika, oregano, salt). Let it toast for 30 seconds.
- Add the mix-ins: Fold in Rotel, beans, and corn. Simmer 2–3 minutes to meld flavors.
- Make it creamy: Stir in your creamy element—canned soup for classic or the quick sauce below. Heat until just thick and glossy.
- Layer the base: Add a thin layer of the meat mixture to the baking dish. Top with a layer of crushed Doritos or torn corn tortillas.
- Build the casserole: Repeat layers of meat mixture, cheese, and chips/tortillas. Finish with a generous blanket of cheese.
- Bake to bubbly: Bake 15–18 minutes until hot and melty. For extra crunch, broil 1–2 minutes—watch closely.
- Rest and garnish: Let stand 5–10 minutes to set. Top with green onions, jalapeños, cilantro, and a squeeze of lime.
Pro Tips
- Keep chips crisp: Cool the meat mixture for 5 minutes before layering and save most chips for the top layer.
- No-cream-soup swap: Whisk 1 cup milk, 1/2 cup sour cream, and 4 oz cream cheese over low heat until smooth; season with salt, pepper, and a pinch of cumin.
- Cheese matters: Freshly shred for the best melt. Blend cheddar + pepper jack for flavor and stretch.
- Spice it right: Mild? Use regular Rotel and omit jalapeños. Spicy? Add chipotle powder or hot Rotel.
- Slow cooker shortcut: Layer in a slow cooker on LOW 2–3 hours; uncover last 15 minutes to prevent sogginess.
- Make-ahead magic: Assemble without the top chip layer, refrigerate up to 24 hours; add chips and bake right before serving.
- Clean slices: Let it rest 10 minutes before cutting so layers hold like a taco lasagna.
- Serving idea: Pair with a simple salad or cornbread—browse ideas here: salad, cornbread.

FAQ
How do I keep the Doritos from getting soggy in Mexican trash casserole?
Layer most of the chips on top, cool the filling 5 minutes before assembling, and broil the last minute. You can also add a fresh handful of chips after baking for extra crunch.
Can I make this without cream of chicken soup?
Totally. Whisk milk, sour cream, and cream cheese over low heat until smooth, then season. It’s velvety, no cans required, and tastes like a white queso base.
What chips work best—Doritos or tortillas?
Doritos bring bold flavor and a party vibe; corn tortillas or tortilla chips hold up better in layers. Want both? Do tortillas in the middle and Doritos on top. Best of both worlds.
Can I prep this Mexican casserole ahead of time?
Yep. Assemble without the top chip layer and refrigerate up to 24 hours. Add chips + cheese and bake when you’re ready. The texture stays great this way.
Does this freeze well?
It does. Freeze unbaked without the top chips for up to 2 months. Thaw overnight, add chips and cheese, and bake. Or freeze baked portions and reheat in the air fryer for crispy edges fast.
What’s the best cheese for a cheesy taco casserole?
A blend of cheddar and pepper jack melts perfectly and adds flavor. Monterey jack is extra gooey; Colby is stretchy. Freshly shredded beats bagged every time for meltiness.
Can I make this gluten-free or keto?
Gluten-free is easy with GF tortilla chips and seasoning. For keto, skip corn/beans, use cauliflower rice layers, and top with crushed pork rinds instead of chips. Still cheesy, still awesome.
Can I cook it in a slow cooker?
Yes! Layer in a slow cooker and cook on LOW 2–3 hours. Crack the lid or uncover near the end to prevent steam from softening the topping. Add a fresh chip layer before serving for crunch.
What should I serve with this?
Keep it simple: crisp salad, limey slaw, or cornbread. Find sides here: salad ideas, slaw, cornbread.

Servings: 8 servings
Equipment
- Large skillet
- 9×13-inch baking dish
Ingredients
Ingredients
- 1 lb lean ground beef
- 1 small yellow onion, diced
- 1 oz taco seasoning packet
- 1 can (10 oz) diced tomatoes with green chiles undrained
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (15 oz) corn kernels, drained
- 1 can (10.5 oz) condensed cream of mushroom soup
- 0.5 cup sour cream
- 2 cups shredded Mexican blend cheese, divided
- 10 oz bag nacho cheese flavored tortilla chips, lightly crushed
Instructions
- Heat the oven to 350°F. Lightly grease a 9×13-inch baking dish.
- Cook the ground beef and diced onion in a large skillet over medium-high heat, breaking up the meat as it browns, 6–8 minutes. Drain off any excess grease.
- Stir in the taco seasoning, diced tomatoes with green chiles (with their juices), black beans, corn, condensed soup, and sour cream. Bring to a gentle simmer and cook 2–3 minutes, stirring, until evenly combined. Off the heat, mix in 1 cup of the shredded cheese.
- Spread the crushed tortilla chips over the bottom of the prepared baking dish. Spoon the beef mixture evenly over the chips and sprinkle with the remaining 1 cup cheese.
- Bake until the casserole is bubbling around the edges and the cheese is melted, 20–25 minutes. Let rest 5–10 minutes before serving so it sets slightly.
Notes
For extra kick, add a pinch of crushed red pepper or a diced jalapeño with the onion. Swap cream of mushroom with cream of chicken if preferred. Leftovers keep in an airtight container in the fridge for up to 3 days; reheat covered at 350°F until warmed through.
