I was looking for a different recipe to use up white corn tortillas and some leftover chicken. I came across a treasure trove of recipes out there for a Texas dish called King Ranch Casserole. It is basically layers of tortillas, chicken, cheese, and a sauce with–you guessed it, condensed cream of mushroom and chicken soup. However, I did come across of a few other recipes that actually made the sauce from scratch with butter, flour and broth. Now we are talking. With a few tweaks here and there I have come up with a definite crowd pleaser. I believe my husband’s exact words were, “Don’t forget about this one!” Bonus to the blog! The recipe is now published.
We enjoyed this with a side of Quick Stewed Black Beans and a simple salad.

Chicken Tortilla Casserole

Equipment
- 9 x 13-inch baking dish
Ingredients
- 3 cups leftover chicken, I had one breast, 2 thighs, 2 drums
- 3 tablespoons unsalted butter
- 1 yellow onion, finely diced
- 3 cloves of garlic, minced
- 1 red bell pepper, finely diced
- 1 poblano pepper, finely diced
- 1 (10 ounce) can of Ro-tel tomatoes with green chiles
- 3 tablespoons all-purpose flour
- 2 ½ teaspoons chili powder
- ½ teaspoon oregano
- 1 teaspoon ground cumin
- 1 ½ cups chicken stock
- ½ cup whole milk
- ½ cup sour cream
- 1 tablespoon freshly squeezed lime juice
- ½ cup cilantro, chopped
- 2 cups Chihuahua cheese, grated (about 8 ounces)
- 1 cup Monterey Jack cheese, grated (about 4 ounces)
- 12 white corn tortillas
- Kosher salt and freshly ground black pepper to taste
Instructions
- Butter the sides and bottom of a 9 x 13-inch baking dish. Preheat the oven to 350ºF.
- In a large saucepan melt the butter over medium heat. Add the onions and peppers and cook until softened, about 10 minutes. Add the garlic and cook for another 2 minutes. Add the flour, chili powder, oregano, and cumin and cook for 1 minute. Add the chicken broth and stir to thicken the sauce. Reduce the heat to a simmer and add the milk and Ro-Tel. Cover the saucepan and simmer for 15-20 minutes stirring occasionally. Remove the pan from the heat and stir in the sour cream and the lime juice. Season to taste with salt and pepper.
- Cut each tortilla in half for easy placement in the baking pan. Ladle 1 cup of the sauce onto the bottom of the pan. Layer half the tortillas on top of the sauce cut sides facing out (a few will go in the center to cover any holes). Add half of the chicken, half of the remaining sauce, half of the cilantro and half of the grated cheese blend. Repeat the layering of tortillas, chicken, sauce, cilantro and finish with the remaining cheese. Cook uncovered for 30-45 minutes or until brown and bubbling. Let stand 10 minutes before serving. Serve with a good hot sauce like Cholulua. Enjoy!

I love clicking onto your site and seeing what new recipe you have posted for the day! Yes I was shocked that you made casserole, but i can't wait to try it!
Sounds awesome, would it work without the chicken?
Shawna- Absolutely. You can use any meat of your choice, like shrimp or pork. But, if you are looking for a vegetarian version, then I would substitute the meat with more vegetables, like sautéed zucchini,spinach, black beans, and/or corn. Thanks for the question.
made this tonight for dinner…YUMMY! Thanks for sharing! I shared it on my blog's weekly menu and pointed people here to find it!
Hi Nicole
I do not like cumin, is there another spice I could use in place of it.
I would just omit it.
Did you fry or baked your tortilla's before assembling the bake? Seems that they would get soggy. No? Making your fabulous dish right now!
The tortillas are not baked or fried, but for a light smokey flavor you can warm them over a gas flame.
I've been making this since 2015 and it's so addictive and simple. I use the sauce for chicken enchiladas, just dipping regular ole tortilla chips in and steak street tacos ect. It's that amazing and flavorful!
