Ingredients
- 3 cups cooked shredded chicken
- 10 corn tortillas, cut into quarters
- 1 can (10.5 oz) cream of chicken soup
- 1 can (10.5 oz) cream of mushroom soup
- 1 can (10 oz) diced tomatoes with green chilies
- 1 small onion, diced
- 1 green bell pepper, diced
- 2 cups shredded cheddar or Monterey Jack cheese
- 1 tablespoon butter
- 1 teaspoon chili powder
- Salt and black pepper to taste
How to Make King Ranch Chicken Casserole
Step 1: Prepare the Vegetables
Preheat your oven to 350°F (175°C).
Melt the butter in a large skillet over medium heat. Add the diced onion and bell pepper and cook for about 5 minutes, or until the vegetables begin to soften.
Step 2: Make the Creamy Sauce
Add the cream of chicken soup, cream of mushroom soup, and diced tomatoes with green chilies to the skillet. Stir in the chili powder, salt, and black pepper.
Cook for a few minutes, stirring occasionally, until the mixture is hot and well combined.
Step 3: Add the Chicken
Stir the shredded chicken into the creamy sauce. Mix until the chicken is evenly coated and everything is heated through.
Step 4: Layer the Casserole
Lightly grease a 9×13-inch baking dish.
Arrange a layer of quartered tortillas across the bottom. Spread some of the chicken mixture over the tortillas, followed by a layer of shredded cheese.
Repeat the layers until all the ingredients have been used, finishing with plenty of cheese on top.
Step 5: Bake
Cover the casserole loosely with aluminum foil and bake for about 25 minutes.
Remove the foil and continue baking for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden.
Allow the casserole to rest for about 5–10 minutes before slicing and serving.
Tips for the Best Results
Use leftover roasted chicken or rotisserie chicken to make preparation even easier. Don’t make the tortilla layers too thick, as you want the sauce to soak into them during baking.
For extra flavor, add a little cumin, smoked paprika, or chopped jalapeño. Monterey Jack or a Mexican cheese blend also works beautifully if you prefer a creamier, more flavorful cheese topping.
What to Serve With It
King Ranch Chicken Casserole pairs well with simple sides such as:
- Green salad
- Mexican rice
- Refried beans
- Corn
- Avocado
- Fresh salsa
Storage and Reheating
Store leftover casserole in an airtight container or cover the baking dish tightly and refrigerate for up to 3–4 days.
Reheat individual portions in the microwave or warm the casserole in a 350°F oven until heated through. The casserole can also be frozen for longer storage.
Conclusion
King Ranch Chicken Casserole is the perfect combination of creamy sauce, tender chicken, soft tortillas, flavorful vegetables, and melted cheese. It’s easy enough for a weeknight meal but comforting enough for a family gathering.
With its rich Tex-Mex flavors and simple preparation, this classic casserole is sure to become a favorite at your dinner table.
