How to Make King Ranch Chicken Casserole
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. Spray a 9x13 inch baking dish with cooking spray to prevent sticking.
Step 2: Sauté the Vegetables
Heat olive oil over medium heat in a large skillet. Add the chopped onion, green bell pepper, and minced garlic, sautéing until they are soft. Remove from heat and stir in the shredded chicken until well combined.
Step 3: Mix the Sauces
In a large mixing bowl, combine the cream of chicken soup, cream of mushroom soup, (optional) chicken broth, diced tomatoes with green chiles, chili powder, cumin, salt, and pepper. Stir until everything is well mixed.
Step 4: Layer the Ingredients
Place half of the torn tortillas in the prepared baking dish. Add half of the chicken mixture, then half of the soup mixture. Top with half of the shredded cheese before repeating the layers with the remaining ingredients. Finish by topping with the last of the cheese.
Step 5: Bake the Casserole
Bake in the preheated oven for 40-45 minutes. The casserole should be bubbly and the cheese melted and slightly golden on top.
Step 6: Garnish and Serve
Once out of the oven, sprinkle chopped fresh cilantro on top if desired. This adds a fresh touch to the dish.
