Beef Dorito Casserole
Ingredients:
Ingredient Quantity
Lean ground beef 1 lb
Yellow onion, diced 1
Red pepper, diced 1
Taco seasoning 1 (1 oz) package
Water or beef broth ½ cup
Tomatoes and green chiles, drained 1 (14.5 oz) can
Black beans, drained and rinsed 1 (15 oz) can
Sour cream ¾ cup
Cool Ranch Doritos 1 (9 oz) bag
Shredded Mexican blend cheese 3 ½ cups
Sour cream and salsa For topping (optional)
Instructions:
Preheat Oven & Prep Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Brown Beef & Sauté Veggies: In a large skillet over medium heat, add the ground beef. Break it apart with a spoon and cook until browned. Drain any excess grease. Return the pan to the stove. Add the diced red bell pepper and diced yellow onion. Continue cooking for 3-4 more minutes, stirring occasionally, until the onion has softened.
Season & Simmer: Stir in the taco seasoning and water (or beef broth). Reduce the heat to low and let the mixture simmer for 5-6 minutes, or until the liquid has thickened.
Add Final Mix-ins: Remove the skillet from the heat. Stir in the drained canned tomatoes and green chiles, the sour cream, and the drained and rinsed black beans. Stir everything until well combined.
Layer the Casserole:
Slightly crush about 1 cup of the Cool Ranch Doritos and spread them in the bottom of the prepared baking dish to form the first layer.
Spoon half of the skillet mixture evenly over the crushed chips.
Top this with another layer of crushed Doritos and half of the shredded Mexican blend cheese.
Spoon on the remaining skillet mixture.
Finish by topping with the remaining crushed chips and the remaining Mexican blend cheese.
Bake: Bake for 25-30 minutes, or until the casserole is bubbling around the edges and the cheese on top is melted and starting to brown.
Serve: Remove from the oven and serve hot. Top individual servings with extra sour cream, salsa, hot sauce, and green onions if desired.
