Ingredients

¾ cup Doritos or tortilla chips
1 lb ground beef
1 small yellow onion, diced
¾ cup sour cream (do not use light sour cream)
2 cups shredded Cheddar cheese
1 (16 oz) can refried beans
2 tbsp taco seasoning
¼ cup sliced black olives

For Garnish:

Green onions
⅓ cup diced fresh tomatoes
⅓ cup shredded lettuce (optional)

Instructions

Preheat the Oven:
Preheat your oven to 350°F (175°C).
Cook the Beef and Onions:
In a skillet over medium heat, sauté the diced onion and ground beef until the onions are translucent and the beef is browned. Drain any excess fat.
Add Seasoning:
Stir in the taco seasoning and ¾ cup of water. Bring the mixture to a boil, then reduce the heat and cook for 5 minutes. Remove from heat and set aside to cool.
Layer the Casserole:
In a 9×13-inch baking dish, spread the refried beans evenly across the bottom.
Add a layer of sour cream on top of the beans.
Next, layer the cooled ground beef and onion mixture.
Sprinkle the shredded Cheddar cheese evenly over the top.
Bake the Casserole:
Bake the casserole uncovered for 15 minutes, or until the cheese is melted and bubbly.
Add Olives and Chips:
Top the casserole with sliced black olives and Doritos or tortilla chips. Return to the oven and bake for an additional 8 minutes.
Finish and Garnish:
Remove from the oven and garnish with diced fresh tomatoes, chopped green onions, and shredded lettuce (if using).

Tips

For extra crunch: Use Doritos for a burst of flavor or tortilla chips for a more traditional option.
Don’t skip draining the beef: Draining excess fat ensures your casserole isn’t greasy.
Let it cool slightly: Let the casserole sit for a few minutes before slicing to allow the layers to set.

Variations and Substitutions

Vegetarian Version: Replace the ground beef with a plant-based meat substitute or black beans for a vegetarian taco casserole.
Cheese: Swap the Cheddar cheese for a combination of Monterey Jack and Pepper Jack for a spicy twist.
Beans: Use black beans or pinto beans as an alternative to refried beans for a different texture and flavor.
Taco Seasoning: If you don’t have taco seasoning, you can mix chili powder, garlic powder, cumin, and paprika to create your own seasoning blend.
