Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish to ensure the casserole doesn’t stick.
2. Cook the Ground Beef:
In a large skillet over medium heat, cook the ground beef until it’s no longer pink. Drain any excess grease to keep the casserole from being too oily.
3. Add Vegetables:
Add the chopped onion and red bell pepper to the skillet. Cook until the vegetables are soft and fragrant, about 5 minutes.
4. Season the Beef:
Stir in the taco seasoning packet and cook for another 2 minutes, allowing the flavors to meld together.
5. Prepare the Creamy Mixture:
In a large mixing bowl, combine the sour cream, mayonnaise, and 1 cup of shredded cheddar cheese. Mix until smooth and well combined.
6. Layer the Corn Chips:
Spread the crushed corn chips evenly across the bottom of the prepared baking dish, creating a crunchy base.
7. Add the Beef Mixture:
Spread the cooked ground beef mixture over the layer of corn chips, ensuring an even distribution.
8. Add the Creamy Layer:
Spoon the sour cream mixture over the ground beef, spreading it out evenly.
9. Add Diced Green Chilies:
Sprinkle the diced green chilies over the sour cream layer, adding a hint of heat.
10. Add More Cheese:
Top with the remaining 1 cup of shredded cheddar cheese, covering the surface evenly.
11. Add Tomatoes and Green Onions:
Arrange the sliced tomatoes on top of the cheese layer, followed by a sprinkle of sliced green onions.
12. Season to Taste:
Season with salt and pepper to taste, adjusting to your preference.
13. Bake the Casserole:
Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the casserole is bubbly and the cheese is melted and golden.
14. Let it Rest:
Allow the casserole to rest for a few minutes before serving, letting the layers settle and making it easier to slice.
