Key Ingredients King Ranch Casserole

Here’s what you need to make this amazingly flavorful and simple meal:

• Chicken: For this casserole, I’m starting with pre-cooked and shredded chicken. The easiest way to get this is to buy a rotisserie chicken from the grocery store, but you can also poach a couple of chicken breasts, or use leftover chicken in this recipe.
• Tortillas: Corn tortillas add structure to the casserole and help to create layers. Any size tortillas can be used, although you may need to cut them if they are larger than your casserole dish.
• Peppers: The savory and slightly spicy flavor of this dish comes from three types of fresh peppers. Bell pepper for sweetness, and jalapeno and poblano for spice!
• Rotel: Rotel is a name brand for canned diced tomatoes with green chiles. Those chiles add even more big flavor, but if you prefer something milder, plain diced tomatoes can also be used.
• For the Sauce: There is no canned soup in my king ranch casserole recipe! Instead, we’ll build a sauce with the peppers, Rotel, onion, garlic, butter, flour, broth and sour cream. It’s so delicious, and a thousand times better than anything you’ll get from a can!
• Cheese: Two cups of shredded cheese make this casserole perfectly ooey-gooey! Cheddar or Monterey Jack both work equally well.

How To Make The Best King Ranch Chicken Casserole

1. Saute the Vegetables: In a large skillet, melt the butter over medium heat. Add the onion, red bell pepper, poblano pepper, and jalapeno. Cook for about 3-4 minutes until the vegetables are soft. Add the minced garlic and cook for another minute. Once the veggies are cooked, stir in the chili powder, ground cumin, and garlic powder.
2. Add the Flour: This is what will thicken the sauce later. Sprinkle the flour over the vegetables, then stir it in and cook for about 30 seconds.
3. Add Broth: Gradually stir in the chicken stock, stirring continuously to avoid lumps. Cook for a few minutes until the mixture thickens slightly.
4. Then, add the cooked shredded chicken and diced tomatoes. Season with salt and pepper. Cook for another 5 minutes, then remove from heat.

5. Start Layering: To a lightly greased 9×13-inch baking dish, spread a thin layer of the chicken sauce, then top with 6 corn tortillas. The tortillas should overlap and it’s ok that there are gaps on the edges.
6. Keep Layering: Spread half of the remaining chicken filling over the tortillas, then top with half of the shredded cheddar cheese.

7. Repeat! Repeat the layers again (tortillas, chicken, and cheese) to use up all of the ingredients.
8. Bake: Bake in a preheated 350°F (180°C) oven for 35-40 minutes, or until the cheese is bubbly and slightly browned.

Recipe Tips

• To make shredded chicken: You can cook chicken in so many different ways to use in this recipe! Here are a few options: boiled chicken breast or slow cooker shredded chicken. If you need a quick shortcut, buy a rotisserie chicken at the store! Be sure to shred the chicken into bite-sized pieces, but not so small that you lose all of the meaty texture.
• Add-Ins to try: This casserole would be delicious with black beans, corn, or any other veggies you might like.
• For a milder casserole, skip the poblano and jalapeno and use two bell peppers instead. You can also leave out or reduce the amount of chili pepper called for here.
• Make it gluten-free. Replace the flour with your favorite 1:1 gluten-free flour. For a low-carb casserole option, you might also like to try my Chicken Fajita Casserole recipe.
