Seriously…it’s sooooo good! You’re going to NEED to make this Tex-Mex casserole ASAP!
The jury is still out as to who really created the King Ranch Casserole. Word on the street is that its name comes from the largest ranch in the United States, King Ranch in South Texas. There is no definitive connection between the dish and the ranch though.
The original recipe calls for pulled chicken, canned soup, green chiles, cheese, corn tortillas sour cream and a few other veggies. I decided to go the extra mile and make the canned soup from scratch. It’s so easy and much less sodium because I use low-salt broth.
King Ranch Chicken Casserole Ingredients
- yellow onion
- red bell pepper
- poblano peppers
- jalapeño pepper
- diced tomatoes
- chili powder
- cayenne powder
- all-purpose flour
- low-sodium chicken broth
- 6-inch corn tortillas
- shredded Monterey Jack cheese
- shredded cooked chicken
- sour cream
- kosher salt
How to make this King Ranch Chicken Casserole
First, you’ll melt your butter in a large skillet and then add your onions, red bell pepper, poblanos and jalapeno and cook until everything is softened, about 8-10 minutes.
Next up, you will add your garlic, diced tomatoes and spices and continue to cook for 1-2 minutes, stirring often so you don’t burn the garlic. You will add your flour next and cook for about 1-2 minutes and then slowly add your broth until the mixture thickens, about 2-3 minutes.
At this point, you’ll remove your skillet from the heat and stir in your sour cream and your shredded chicken until everything is smooth and creamy and well combined.
I decided to use the same cast iron casserole skillet, so I transferred the mixture to a bowl and rinsed the skillet before starting my layering. You could also opt to use a 13×9 baking dish at this point.
You’ll spread a thin layer of the sauce on the bottom of whatever dish you’re using followed by 5 of the tortillas ripped into small to medium-ish pieces. Then you will spread half of the remaining sauce over the tortillas followed by half the cheese. Top the cheese with the remaining 5 ripped tortillas, then the remaining sauce, and the leftover cheese.
You’ll bake for about 40-45 minutes until the top is lightly browned and the sauce begins to bubble.
What to serve with this Casserole
- tortilla chips

This casserole is ridiculously delicious and such a family-friendly meal. It’s absolutely perfect for upcoming Cinco de Mayo too!

A Few Cook’s Notes for King Ranch Chicken Casserole
You can make this in a 13×9 baking dish or a 3.6 quart deep cast iron casserole as pictured. Mine is made by Lodge.
I buy my chicken already cooked and shredded from my local market. You’ll need 4 cups. If your market doesn’t carry it you can cook your chicken yourself and shred. You’ll need about 2 large boneless skinless chicken breasts.
I used 6-inch yellow corn tortillas for this recipe, but you could use white corn tortillas instead.
