  • 1 (10.5 oz) can cream of chicken soup

Instructions

  1. Preheat Oven:
    Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.

  2. Sauté Veggies:
    In a large skillet, heat oil over medium heat.
    Add chopped onion and bell pepper. Cook until softened (about 5 minutes).

  3. Make the Sauce:
    Stir in cream of chicken soup, cream of mushroom soup, diced tomatoes with chilies, chili powder, garlic powder, salt, and pepper.
    Simmer for a few minutes until everything is well combined and heated through.

  4. Layer the Casserole:
    In the baking dish, layer half the tortilla pieces on the bottom.
    Top with half the chicken, then half the sauce, and 1 cup of cheese.
    Repeat with remaining tortillas, chicken, sauce, and cheese.

  5. Bake:
    Cover with foil and bake for 30 minutes.
    Uncover and bake an additional 10 minutes, or until bubbly and lightly golden.

  6. Cool & Serve:
    Let the casserole rest for 5–10 minutes before serving for easier slicing.
