1-Start by preheating your oven to 400°F (204°C) and greasing a 9×13-inch (23×33 cm) baking dish, which sets the stage for that crispy finish everyone loves. This approach keeps things simple and efficient, ideal for working professionals or baking enthusiasts.

2-Next, in a large skillet over medium heat, cook 1 pound of ground beef and 1 chopped yellow onion until the beef is no longer pink, then drain any excess fat to keep it lighter. Stir in 2 packages of mild taco seasoning, the drained diced tomatoes, diced green chilies, 1 cup of sour cream, and 1 can of cream of mushroom soup, heating everything through for a creamy base.

3-Now for the fun part: In your prepared baking dish, spread one-third of the crushed tortilla chips at the bottom. Layer half of the beef mixture over the chips, add another one-third of the chips, then the remaining beef mixture. Top with the last third of chips and sprinkle 1 ½ cups each of shredded Monterey Jack and cheddar cheese evenly over the top.

4-Bake uncovered for 20-25 minutes until it’s heated through and the cheese is bubbly let it rest for a bit before serving.
