This homemade king ranch casserole recipe is loaded with shredded chicken, cheese, tortillas, and a creamy filling - made with a flavorful roux instead of canned soups!

When it comes to chicken casserole, my friends, homemade King Ranch Chicken Casserole just might be "king". Casseroles are always a big hit with people, especially in the U.S. Midwest and South, where all of these wonderful flavors are mixed up in a single pan or dish and baked to guilty perfection.
A good chicken casserole is the ultimate comfort food. It warms the bones, makes you feel good, and hey, they're HUGE on flavor. Especially the way I make mine.
This particular dish is a classic casserole recipe. It's called King Ranch Casserole, and you're going to love it. Let's talk about it!

What is King Ranch Casserole?
King Ranch Casserole, also known as "King Ranch Chicken" or "King Ranch Chicken Casserole", is a creamy Tex-Mex casserole made with shredded chicken, tomatoes, green chilies, bell peppers, and onions cooked down with canned creamy soups. It is layered in a baking dish or pan with corn tortillas and cheese, then baked.
The name is apparently associated with the King Ranch in Texas, though people from King Ranch say the recipe didn't originate with them. It is interesting to note that King Ranch is known for its beef, and King Ranch Casserole is a chicken dish.
It is a common potluck dish, popular at parties and gatherings. As with any dish like this, recipes can vary from cook to cook and personal tastes.
The Original King Ranch Casserole
The original King Ranch Casserole recipe calls for a cans of cream of chicken soup and cream of mushroom soup for the creaminess, and Ro-Tel brand diced tomatoes and green chiles, all of which are cooked down with chicken broth, shredded chicken, onion and seasonings. It is then layered with corn tortillas or tortilla chips and shredded cheese and baked.
My version of the recipe skips the soup cans and starts with a roux that is so much more flavorful. It's made from scratch, aside from canned tomatoes, though you can use fresh tomatoes. I'm using fire roasted tomatoes and cooking down peppers and onions in the roux instead of using a can of Ro-Tel, though Ro-Tel is fine here. I'm also using some of my favorite chili powders - ancho and pasilla - though you can season it to your preference, as discussed in the ingredients section.
Let's talk about how we make it, shall we?

Homemade King Ranch Casserole Ingredients
- Vegetable Oil. 4 tablespoons vegetable oil (1/4 cup - or you can use butter).
- Flour. 1/4 cup all purpose flour.
- Onion. 1 medium onion, chopped - yellow onion is good, or use white onion.
- Peppers. 1 large bell pepper, chopped (I use jalapeno peppers for extra heat).
- Garlic. 4 cloves garlic, chopped.
- Chili Powder. 1 tablespoon chili powder (use your favorite blend, or use Tex-Mex seasonings like ancho, pasilla and/or chipotle powders).
- Other Seasonings. I use 1 teaspoon cumin and salt and pepper to taste.
- Chicken Broth. 1 cup chicken broth (or use vegetable broth).
- Tomatoes. 14 ounces fire roasted tomatoes (or use a can of Rotel).
- Sour Cream. 1 cup sour cream or Mexican crema.
- Shredded Chicken. 1 pound shredded chicken (cooked, or you can use chopped).
- Cheese. 4 cups shredded Monterey Jack Cheese (cheddar cheese is good, too, or any melty cheese of choice).
- Corn Tortillas. Use 12 corn tortillas for this recipe.
TOPPINGS: Sliced jalapeno peppers, red chili flakes, fresh chopped cilantro or parsley, extra sour cream or crema
How to Make Homemade King Ranch Casserole - the Recipe Method
First, Make the Roux. Start by heating the oil in a large pan over medium heat (or melt the butter if using butter). Add the flour and stir until it is incorporated. Stir constantly for 10 minutes until the roux begins to turn a light brown. Learn more about How to Make a Roux.
Add the onion and bell peppers. Stir. Cook them down for 5 minutes to soften. The mixture will be somewhat pasty.

Add the garlic and cook for another minute.
Stir in the seasonings - chili powder, cumin, and a bit of salt and pepper.
Stir in the chicken broth and fire roasted tomatoes. The mixture will thicken up slightly like a chunky sauce. Cook for 5 minutes to let the flavors develop.

Remove from heat and stir in the sour cream or crema and cooked shredded chicken.

Preheat your oven to 350 degrees F.
Layer the Casserole. Set 4 tortillas into the bottom of a square casserole dish, then add a few scoops of the saucy vegetable and chicken mixture.

Add a layer of shredded cheese.

Repeat layers with two more layers of 4 tortillas, the chicken and vegetable mixture, and a final layer of shredded cheese.
Bake the casserole for 20-25 minutes, or until the cheese is nice and melty.
Remove from heat and cool slightly. Garnish with your toppings and serve!

This will serve 8 people.
Boom! That's it, my friends! That's how you make a good homemade king ranch casserole with chicken. Pretty easy, right? Easy and tasty!
Recipe Tips & Notes
- The Chicken. I usually use chicken breast for this recipe, but shredded chicken thighs are great here. Use a combination if you'd like. You can also use store bought rotisserie chicken as a time saver, though I enjoy cooking and shredding my own chicken. Try my Easy Shredded Chicken recipe. It's SO juicy.
- The Tortillas. Corn tortillas are traditional, though you can make this with flour tortillas if you'd like. Torn tortillas are often used to fill up the dish better.
- Freeze It. Homemade King Ranch Chicken Casserole can be frozen before baking. Simply prep the recipe in a freezer friendly dish, then bake it from frozen for 45-60 minutes, until it is cooked through.
- How Do You Spice Up Homemade King Ranch Chicken Casserole? It is easy to make a spicier version of this by incorporating hotter peppers, such as jalapenos or serranos, and using a hotter chili powder and spicy red pepper flakes.
- What Goes with Homemade King Ranch Chicken? A salad is a nice side to go with chicken casserole, as is your favorite green vegetable, such as broccoli, green beans or asparagus. Try a sweet potato on the side. Rice is good, too, like Cajun Dirty Rice or Mexican Rice.
I hope you enjoy the casserole! Such a great recipe.
Storage & Leftovers
Storing your Homemade King Ranch Casserole in an airtight container in the fridge may allow you to store the leftovers for up to 3-4 days (2-3 months in the freezer). To maximize the storage life, make sure to refrigerate the dish promptly.

One of my favorite recipes. I halve it and make it in two separate Pyrex bowls so I can make mine spicy. Love it!
Mike H. says
Thank you, Peg!
Craig says
King Ranch chicken has been a favorite of mine all my life. However, the King Ranch name is trademarked and they aggressively defend it. The H-E-B grocery chain based in San Antonio was forced to change the name of their frozen product by this name to South Texas Ranch Chicken or something like that. I’ll have to try this recipe. There’s a similar one called Mexican Sweat that mixes cream of chicken soup, Ranch Style Beans, ground taco meat, RoTel, and maybe some more that slips my mind, layered with tortillas and Velveeta cheese...yum!

Thanks, Craig.
Donna says
I agree with you JoAnnV that the tortillas should be given a light fry in oil so they don't become mushy, but I love the idea of making a roux, instead of using canned soups.
Michael Hultquist - Chili Pepper Madness says
Go for it! Let me know how it turns out for you.
Nunya says
I made this but substituted pork for the chicken...It was a tasty recipe! I also substituted my home canned tomatoes with a good glomp of Ortega diced green chilis, because I didn't have the fire roasted tomatoes. All in all, it was a very good recipe and actually tasted better the next day warmed up. Thanks for something a little different!
Michael Hultquist - Chili Pepper Madness says
Great, thanks!
JoAnn V says
Do you cook the corn tortillas first? I usually do because they seem to become mushy when baked if not. What brand do you use if you do not fry them first?
Michael Hultquist - Chili Pepper Madness says
JoAnn, I do not, but they do get softened in the baking process. I don't use any particular brand for this. You can use your favorite, or make your own.
Jeremie says
Mike, this recipe was a huge success: the roux gives a delicious flavor to the dish. So comforting! Ideal for a cold winter evening!
Michael Hultquist - Chili Pepper Madness says
Outstanding! Thanks, Jeremie. This is one of Patty's favorites. Glad you enjoyed it! Yep, perfect for winter nights.
GrammaSue says
I love your recipe for this. I have never made the soup "version" but the homemade version just seems to be healthier (if that's possible LoL!). I did add jalapenos and a poblano to it as we love spicy dishes. Thanks so much for sharing your GREAT recipe! Love your website!
Michael Hultquist - Chili Pepper Madness says
Thanks so much, GrammaSue! I appreciate it!
