Step-by-Step Instructions
Prepare Your Baking Dish
Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
Cook the Ground Beef
In a large skillet, brown the ground beef over medium-high heat until no pink remains. Drain excess grease to avoid an oily casserole.
Combine the Filling
Stir in taco seasoning, diced tomatoes with chilies (including liquid), refried beans, and enchilada sauce. Simmer for 5 minutes, stirring occasionally to blend the flavors.
Layer the Casserole
Spread half of the crushed Doritos evenly over the bottom of the baking dish. Pour the beef mixture over the chips, ensuring even coverage.
Add the Cheese
Sprinkle cheddar and Monterey Jack cheeses over the top of the beef layer to create a gooey, cheesy topping.
Finish with Doritos
Add the remaining crushed Doritos evenly across the top for added crunch.
Bake to Perfection
Bake for 20–25 minutes, or until the cheese is melted and the casserole is bubbling.
Rest and Serve
Let the casserole rest for 5 minutes before serving. Top with your favorite garnishes like sour cream, salsa, or cilantro for added freshness.
Delicious Variations
Chicken Doritos Casserole
Substitute cooked shredded chicken for the beef for a lighter version.
Vegetarian Version
Skip the meat and double the beans and veggies for a hearty meatless meal.
Creamy Twist
Mix ½ cup sour cream or cream cheese into the beef mixture for a richer filling.
