How to Make Mexican White Trash Casserole Step by Step

Step 1: Preheat the Oven

Set your oven to 350°F (175°C) and lightly grease a 2-quart casserole dish to prevent sticking.

Step 2: Mix the Filling

In a large bowl, combine shredded chicken, cream of chicken soup, Ro’tel tomatoes, sour cream, milk, and taco seasoning. Stir until fully blended and creamy.

Step 3: Layer the Casserole

Spread half of the crushed Doritos on the bottom of the casserole dish. Add half of the chicken mixture on top. Repeat with the remaining Doritos and chicken mixture. Sprinkle shredded cheese over the top if desired.

Step 4: Bake

Cover the casserole with foil and bake for 35 minutes. Remove the foil for the last 10 minutes to achieve a golden, crispy top layer.

Step 5: Serve

Allow the casserole to cool for a few minutes before serving. This gives the layers time to set slightly, making it easier to scoop and enjoy.

Expert Tips

For extra crunch, sprinkle some additional crushed Doritos on top before baking. You can also add diced onions or bell peppers for more flavor. Serve fresh for the best texture—reheated Doritos can lose some crispiness.

Storage & Reheating

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave until warmed through. Add a few extra Doritos on top before reheating to restore some crunch.

What to Serve With

Pair this casserole with a fresh green salad, guacamole, or a side of Mexican rice. A squeeze of lime over the top can also add a nice bright flavor.
