What is King Ranch Chicken?
This classic Southern casserole recipe started in Texas! This classic casserole has earned a spot in most people’s hearts thanks to its easy recipe, comforting nature, and ability to feed the masses.
Although its namesake is the King Ranch, the largest ranch in all of Texas, there’s no history linking the cheesy, creamy casserole to the ranch itself. In fact, there’s no written history of where the casserole DID come from. But Texans happily claim it as their comfort food mascot.
Table of Contents
- Chicken: this recipe uses cooked and shredded chicken; you can make this yourself ahead of time or grab a rotisserie chicken and shred it to save time. If you want to make your own, you can use my method here in this Shredded Mexican Chicken, where the chicken is seared and poached. This method creates a perfectly tender and moist chicken. Just skip the seasoning mixture.
- Tortillas: corn tortillas are the best for this recipe; the texture of the corn blends in with the casserole. The tortillas can be swapped for tortilla chips if you prefer.
- Diced Tomatoes with Green Chiles: any brand will work; Rotel is a popular brand. Store brands will work just as well. If you cannot find either, you can always use a can of diced tomatoes and a can of diced green chiles.
- Cheese: This recipe uses Monterey Jack cheese, a classic Tex-Mex cheese. Feel free to substitute with any cheese of your choice that melts well.
- Jalapeño: this dish has a very mild heat; if you are concerned about the heat amount, you can substitute the jalapeño with a green bell pepper or leave it out altogether.
How to Make (step-by-step)
To get started, let’s talk about the traditional way of making this casserole dish. You combine leftover chicken with cream of mushroom soup and Rotel and layer the mixture with tortillas.
We’re going to make this without the cream of mushroom soup.
So let’s talk about how to make this King Ranch Casserole without canned soup!
- Sauté veggies: In a large skillet over medium heat, melt the butter. Once melted, add the onion and bell peppers. Cook until the veggies are tender. Add in the garlic, cumin, chili powder, salt, and black pepper. Stir to coat the veggies in the seasonings.
- Create roux: Sprinkle the flour into the skillet. Stir to coat the veggies in the flour until it becomes a thick paste. Cook the mixture for a few minutes to thoroughly cook the flour. Pour in the broth and stir. Bring mixture to a boil while stirring and let simmer while stirring for about 2-3 minutes until thick.
- Add the diced tomatoes with green chiles and sour cream to the sauce. Stir to combine.
- Add the shredded chicken to the sauce and stir, coating the chicken entirely in the sauce.
- Briefly fry the corn tortillas in a small amount of oil. Not enough to make them crispy, just enough to soften and heat briefly. Frying brings out the tortillas’ corn flavoring and helps keep some texture when baked in the dish. Quick frying is the same method that I use when making enchiladas.
- Layer the casserole: tortillas, chicken mixture, cheese, and repeat. The casserole ends with a layer of tortillas topped with cheese on the very top. Bake the casserole until bubbly and warmed throughout.
- Use corn tortillas. The flavor and texture are perfect for casseroles!
- Fry the tortillas briefly before layering. I use the same method to make enchiladas. Quick frying in a small amount of oil in a cast iron skillet helps bring out the flavor of the tortilla. It helps them hold up more against the casserole liquid, so they’re not mush.
- Use leftover or rotisserie chicken. Having shredded chicken on hand makes this recipe come together quick and easy!
How to Cook using a Slow Cooker
You can make this casserole recipe in a slow cooker! To do that, follow the instructions through step 6. Instead of layering the casserole in a dish, put the layers into your slow cooker. You can also make it easier to dish and serve by cutting the tortillas into smaller bite-size pieces, about one and 1/2-inch squares.
Set this to low and let heat for about 1-2 hours. Heat the casserole thoroughly and wait for the tortillas to soften.
- Cornbread: serve this casserole with a side of Buttermilk Cornbread or spice it up with some Jalapeño Cheddar Cornbread.
- Vegetables: roasted vegetables are a healthy side dish for most meals. This dish will pair nicely with some roasted Mexican vegetables, Grilled Mexican Street Corn, Tex Mex Roasted Potatoes.
- Salad: a cold, crisp salad topped with some homemade ranch dressing, blue cheese dressing, or avocado ranch dressing are all favorites. Or serve a fun Classic Wedge Salad.
- Beans: a classic Tex-Mex side dish, beans are always a standby. Try our Borracho Beans, Charro Beans or Authentic Refried Beans with this cheesy casserole.
Freezing and Storage
- Make Ahead: This meal is perfect for preparing ahead of time to quickly and efficiently serve dinner, especially on busy nights. First, prepare the casserole, wrap it tightly, and refrigerate it for one day before baking. Then, let the dish rest at room temp for 30 mins before baking.
- Freezing: For best results, freeze the casserole wrapped in plastic wrap and foil for up to 3 months. Then, thaw it overnight in the fridge before letting it come to room temperature for 30 minutes and baking according to the recipe instructions.
- Storage: Keep leftover casserole fresh by storing it in an airtight container in the fridge for up to 4 days or freezing it for up to 3 months.

I magically happened to have all the ingredients on hand, except for the Rotel. No problem, I had a can of regular diced tomatoes, and I went out to my garden and picked 2 jalapenos, fine diced them and added them.
Heat was VERY prominent in it, but that’s perfect, as my boyfriend and I are both teflon-mouth-coated spice fiends!
Yummy, and a nice surprise for us, as we also love Yellowstone (the ranch-themed tv show)!!
I love your recipes! Question for this one though. I see “and stir in the diced tomatoes with green chiles” in the directions (#5) but I don’t see diced tomatoes in the list of ingredients.
Hi Jenny! Thanks so much! And you’re right that is a typo. It’s suppose to list a 10 ounce can of diced tomatoes and green chiles (rotel), not just diced green chiles. That would be a lot of chiles.. I’ll get that updated!
A great meal and not using canned creamed soup was perfect. I added black beans and kernel corn to the recipe. It was a big hit with my family.
I searched over 20 king ranch recipes before finding yours, as I was specifically looking for something without canned soups on it. Thank you!!
I’m a Texan and I’ve made several versions of this recipe but I must say this one is my favorite and definitely one that I will make again and again thank you so much for sharing
Thanks for the recipe. I searched online for King Ranch Chicken Casserole, and none of them “floated my boat”. I liked the looks of yours, easy. I followed your directions mostly, but I spread refried beans on each corn tortilla to add more protein and substance, I also added a cup of shredded mozzarella to the chicken mixture and mixed it all together.
Everything else remained the same, it turned out very well, my Ladies expressed their approval, so we’re good!
I made this dish for a potluck and it was delicious! Got so many compliments and I didn’t have to bring back leftovers. I made a tiny modification, however, instead of placing it in the oven, I layered it in a crockpot instead and I ripped the tortillas into smaller pieces so it would be easier to serve. I’ll definitely make this again!
Love that idea! So glad that you enjoyed the recipe! Thanks for sharing your tips 🙂
Serene gracias por tu aportacion saludos desde ECUADOR…
SIGO GASTRONOMIA 🙂
Wonderful!!!! This was my first time making King Ranch and my whole family loved it. They said it a keeper. I also appreciate there is not canned cream soups! Thank you for sharing this great recipe.
So glad you enjoyed! Thanks!
This is not the original King Ranch Casserole . I was looking for the original recipe. Original does not have sour cream.
Hi Marie. You’re right, this is not THE original. This is my version. The original uses canned of cream soups which I avoid in my home cooking. So the recipe I made has to take that into consideration, which is where the sour cream comes in.
