Ingredients
For the Meat Mixture
- 1 pound lean ground beef
- 1 cup chopped yellow onion
- 1 cup chopped red bell pepper
- 1 (1-ounce) packet taco seasoning
- 1 /2 cup water
- 1 (14.5-ounce) can diced tomatoes and green chiles (such as ROTEL®), drained
- 1 (15-ounce) can black beans, drained and rinsed
For Assembly
- 1 (9¼-ounce) bag nacho cheese or cool ranch Doritos®, lightly crushed (about 5 cups)
- 3 cups shredded Cheddar-Jack cheese
For Serving
- 1 tomato, chopped, or to taste
- 2 tablespoons chopped fresh cilantro, or to taste
- 1 /2 cup salsa, or to taste

Instructions
Preparation
- 1 Gather all ingredients and preheat your oven to 350°F (175°C). Lightly grease a 3-quart baking dish with nonstick spray. This size ensures proper layering and even cooking throughout the casserole.
- 2 Using a cast iron skillet or large non-stick pan, cook the 1 pound ground beef over medium heat until completely browned, about 6-8 minutes. Break up the meat with a wooden spoon as it cooks to ensure even browning. Drain any excess grease to prevent a greasy finished dish.
Building the Flavor Base
- 3 Add the 1 cup chopped onion and 1 cup chopped red bell pepper to the browned beef. Continue cooking until the vegetables are tender and the onions become translucent, about 5 minutes. The vegetables should soften but still retain some texture for the best final result.
- 4 Sprinkle the taco seasoning packet over the meat and vegetable mixture, then add 1/2 cup water. Stir thoroughly to distribute the seasoning evenly. Simmer the mixture until the liquid thickens and coats the meat, about 5 minutes. This step is crucial for developing deep, concentrated flavors.
- 5 Remove the skillet from heat and stir in the drained diced tomatoes and green chiles, black beans, and 1 cup sour cream. Mix until the sour cream is completely incorporated and the mixture is creamy and well-combined. The residual heat will warm these ingredients without curdling the sour cream.
Assembly and Baking
- 6 Sprinkle 1½ cups of the crushed Doritos evenly across the bottom of your prepared baking dish. Press them down gently to create a solid base layer that will absorb the flavorful juices during baking.
- 7 Evenly spoon about half of the meat mixture over the chip layer, spreading it to the edges of the dish. This ensures every portion gets an equal amount of the savory filling.
- 8 Top with another 1½ cups crushed Doritos and 1½ cups of the shredded cheese. The cheese will melt and bind the layers together while creating that irresistible stretchy texture.
- 9 Repeat the layering process with the remaining meat mixture, then finish with the remaining crushed Doritos and 1½ cups cheese on top. This creates distinct layers that hold their shape when served.
- 10 Bake in the preheated oven for 25 minutes, or until the cheese is completely melted, bubbly around the edges, and the top is golden brown. The casserole should be heated through to the center.
- 11 Remove from oven and top immediately with chopped tomato, fresh cilantro, and serve alongside salsa and additional sour cream for customizable flavor additions.

Perfect Pairing Suggestions
Beverage Pairings:
A crisp Mexican lager or light beer complements the bold flavors without overwhelming the palate, while the carbonation helps cut through the richness of the cheese and sour cream. For wine lovers, a medium-bodied red wine like Tempranillo or a chilled Rosé provides nice contrast to the spicy elements. Non-alcoholic options include fresh lime agua fresca, iced hibiscus tea, or sparkling water with lime to cleanse the palate between bites.
Side Dish Recommendations:
Balance this rich casserole with fresh pico de gallo and crisp lettuce cups for a refreshing contrast. Mexican street corn salad (esquites) adds sweetness and acidity that pairs beautifully with the savory flavors. Cilantro-lime rice or Spanish rice extends the meal for larger appetites, while refried beans create an authentic Mexican feast. For lighter options, serve with jicama sticks and cucumber slices with chili-lime seasoning.
Complete Meal Ideas:
Start with guacamole and tortilla chips as an appetizer, then serve the casserole alongside warm flour tortillas for those who want to make soft tacos. Grilled corn on the cob with cotija cheese and lime makes an excellent side dish. Finish with tres leches cake or churros with chocolate sauce for a festive Mexican-inspired dinner party.
Occasion Suggestions:
This casserole shines at casual gatherings, potluck dinners, and game day parties where comfort food is king. It’s perfect for Cinco de Mayo celebrations, family reunions, or weeknight dinners when you want something special but manageable. The make-ahead friendly nature makes it ideal for meal prep or busy weeknight entertaining.

Pro Tips and Troubleshooting
Professional Techniques:
Crush your Doritos by placing them in a sealed plastic bag and using a rolling pin for consistent pieces – aim for pea-sized chunks rather than powder for the best texture contrast. Let the casserole rest for 5 minutes after baking to allow the layers to set properly for cleaner serving portions. Pre-cook your vegetables until they’re just tender to prevent excess moisture from making the bottom layer soggy.
Common Mistakes and Solutions:
Avoid over-mixing the sour cream into hot meat, which can cause curdling – remove the skillet from heat first and stir gently. Don’t skip draining the beef fat, as excess grease will pool at the bottom and create an unpleasant texture. Press the chip layers lightly but don’t pack them down completely, as they need space to absorb flavors while maintaining some crunch.
Storage and Make-Ahead:
This casserole can be assembled up to 24 hours ahead – just cover tightly and refrigerate, then add 10 extra minutes to the baking time. Leftover portions keep for 4 days refrigerated and reheat beautifully in the microwave at 50% power for 2-3 minutes to prevent the cheese from becoming rubbery. Individual portions can be frozen for up to 3 months – thaw overnight and reheat in a 350°F (175°C) oven for 15 minutes.
Scaling and Presentation:
Double the recipe easily by using a 9×13 inch baking dish and increasing baking time by 10-15 minutes. For elegant presentation, use individual ramekins with 1/3 cup portions – reduce baking time to 15-18 minutes. Garnish strategically by arranging toppings in sections rather than scattering randomly for a restaurant-quality appearance.

This Dorito Casserole represents everything we love about comfort food – it’s familiar yet exciting, simple yet satisfying, and absolutely guaranteed to become a regular rotation recipe in your household. The beauty lies not just in its incredible flavors, but in how it brings people together around the dinner table, creating those memorable moments that make cooking worthwhile.
