Instructions
Preheat your oven to 350°F (175°C). Spray a 9×13 inch rectangular casserole dish with non-stick cooking spray to prevent sticking.
In a large skillet or pan over medium-high heat, brown the ground beef, breaking it apart with a wooden spoon as it cooks. Once fully browned, drain any excess fat. If using taco seasoning, add it to the meat now and stir to combine.
To the cooked ground beef, add the cheddar cheese soup, cream of chicken soup, evaporated milk, and diced green chilies. Stir to combine all ingredients thoroughly. Cook over medium heat, stirring occasionally, until the mixture comes to a gentle bubble and is heated through.
Take half of the Doritos (about 7 ounces) and spread them across the bottom of the prepared casserole dish. Lightly crush them as you add them, but leave plenty of larger pieces for texture. You want them broken but not pulverized.
Carefully spoon half of the hot meat and cheese sauce mixture over the layer of chips, spreading it evenly to cover. Sprinkle 1 cup of the shredded Mexican cheese (or more if desired) evenly over the meat layer.
Add another layer using the remaining Doritos, followed by the rest of the meat mixture. Top with the remaining shredded cheese, creating a generous cheesy crust that will melt beautifully while baking.
Place the casserole in the preheated oven and bake for approximately 20 minutes, or until the cheese is completely melted and bubbly, and everything is heated through. The edges should be slightly golden and bubbling.
Remove from the oven and let the casserole rest for 5 minutes before serving. This helps it set up slightly for easier serving. Cut into portions and serve hot, offering optional toppings like sour cream, green onions, tomatoes, avocado, or salsa for everyone to customize their serving.
Notes
- For a spicier version, add jalapeños to the meat mixture or use Flamin’ Hot Doritos instead of Nacho Cheese.
- This casserole is very forgiving – you can add additional vegetables like corn, black beans, or diced bell peppers to the meat mixture.
- The chips on the bottom layer will soften somewhat during baking, creating a delicious texture contrast with the crunchier top layer.
- Leftovers can be stored in the refrigerator for up to 3 days, though the chips will continue to soften over time.
