- Cooking Instructions: 
- Preheat your oven to 350-375°F. In a skillet over medium heat, cook the ground beef until it's browned, breaking it apart with a spatula. Drain any excess fat from the skillet. 
- Stir in the taco seasoning and simmer the mixture for a few minutes, allowing the flavors to meld and the mixture to thicken. 
- In a 9x13 inch baking dish, spread half of the crushed Doritos evenly across the bottom. Layer the beef mixture on top, followed by another layer of crushed Doritos. 
- Spread a layer of sour cream over the beef mixture for added moisture and flavor. Then, sprinkle a generous amount of shredded cheddar and Monterey Jack cheese on top. 
- Cover the dish with aluminum foil and bake it in the preheated oven for 15-20 minutes. After that, uncover the dish and bake for an additional 5-10 minutes, or until the cheese is melted and bubbly. 
- Once done, remove the casserole from the oven and let it rest for a few minutes before serving. Top with diced tomatoes, green onions, and any other desired toppings like salsa or chopped cilantro. 
- Extra Tips: 
- For added texture and flavor, consider incorporating black beans and corn into the beef mixture. Additionally, using different flavors of Doritos can enhance the overall taste of the casserole. 
- You can also experiment with different cheese blends to suit your taste preferences. 
- Be sure to let the casserole rest before serving to allow the layers to set, making it easier to cut and serve. 
- Enjoy your delicious Dorito casserole!
