King Ranch Chicken is a creamy, cheesy Tex-Mex casserole layered with shredded chicken, peppers, green chilies, and corn tortillas that comes together in under an hour. It’s a cozy, family-friendly dinner for busy weeknights, and it’s an easy one to make for potlucks and game days.
King Ranch Chicken is a Texas classic that shows up in community cookbooks and on potluck tables all over the state. It takes its name from the famous King Ranch in South Texas, although as far as I can tell nobody has ever managed to trace the recipe back to the ranch itself, which makes it a bit of a delicious mystery. Early versions leaned on canned cream soups, but my approach swaps them for an easy from-scratch sauce that tastes so much better.
The sauce is really what makes this casserole. It’s made with butter, flour, broth, and milk, then stirred with sour cream, tomatoes, green chilies, and a mix of warm spices until it turns creamy and gently zesty. I used mild green chilies so the whole table can enjoy it, and it’s easy to turn up the heat if your crowd likes a kick.
Corn tortilla pieces soak up that sauce as it bakes and soften into tender layers, a bit like a lasagna with Tex-Mex vibes. Sharp cheddar goes between every layer and over the top, and it melts into bubbly, lightly browned edges that everyone will fight over. A scoop of cool sour cream and a few slices of avocado on top finish it off.

What You’ll Need
Scroll down to the recipe card below this post for ingredient quantities and full instructions.
- Salted Butter: A little goes into softening the vegetables and the rest into the roux, which is the base of the sauce. Unsalted butter works if you add an extra pinch of kosher salt.
- Yellow Onion: Adds a mellow sweetness that rounds out the spices. A white onion works the same way.
- Green Bell Pepper: Adds a fresh, savory bite that keeps the creamy sauce from feeling too rich. Any color of bell pepper will work in a pinch.
- Red Bell Pepper: Brings sweetness and a pop of color that shows up in every scoop.
- All-Purpose Flour: Cooks in the butter to thicken the sauce so it clings to the tortillas. A 1:1 gluten-free flour blend works as a straight swap.
- Chicken Broth: Forms the savory body of the sauce. Vegetable broth works if that’s what you have.
- Milk: Makes the sauce creamy without being heavy. Half-and-half will make it a little richer, and no other changes are needed.
- Petite Diced Tomatoes: Adds a little acidity and body to balance the cheese and cream. Regular diced tomatoes work too, and Ro-Tel adds heat.
- Diced Green Chilies: Gives the dish its signature mild, smoky tang. I used mild green chilies here, but hot ones will take it up a level. A pinch of cayenne adds some kick too.
- Kosher Salt: Seasons the whole sauce, which needs it to stand up to the tortillas and cheese.
- Garlic Powder: Adds a savory depth that spreads evenly through the sauce.
- Onion Powder: Reinforces the onion flavor throughout the sauce.
- Celery Salt: Adds a subtle, savory note you can’t quite place but would miss. If you don’t have any, use ½ teaspoon kosher salt in its place.
- Ground Cumin: Brings the earthy warmth that makes this taste like Tex-Mex.
- Chili Powder: Adds a gentle warmth and rounds out the seasoning blend.
- Smoked Paprika: Gives a hint of smokiness. Regular paprika works if that’s what’s in your pantry.
- Coarsely Ground Black Pepper: Adds a mild bite that cuts through the richness.
- Sour Cream: Stirred in off the heat to make the sauce smooth and tangy. Full-fat plain Greek yogurt is a good swap.
- Cooked and Shredded Chicken: Makes this a hearty main dish. Rotisserie chicken is an easy shortcut, and leftover chicken works just as well.
- Frozen Corn: Adds little bursts of sweetness and texture. You can use it straight from the freezer without thawing first.
- Freshly Grated Sharp Cheddar Cheese: Melts into gooey layers and a lightly browned top. Freshly shredded melts more smoothly than the bagged kind. Colby, Mexican blend, Monterey jack, and pepper jack all work well.
- Corn Tortillas: These soak up the sauce as they bake, turning soft and tender. Small flour tortillas work in place of the 5-inch corn ones. If all you have is larger tortillas, cut them into similar-size pieces and use enough to cover each layer.
- Chopped Cilantro, Avocado, or Sour Cream: Optional toppings that add a fresh, cool contrast to the warm casserole. Avocado and extra sour cream are my favorite finishing touches.
How to Make King Ranch Chicken
- Preheat oven. Heat your oven to 350°F (177°C) and lightly spray a 9×13 baking dish with cooking spray.
- Sauté vegetables. Melt 2 tablespoons of the butter in a large skillet over medium heat. Add the onion and both bell peppers, then sauté for about 5 minutes, until softened.
- Make roux. Add the remaining 6 tablespoons of butter to the skillet and let it melt. Sprinkle in the flour and whisk for 1 to 2 minutes.
- Add broth and milk. Slowly pour in the chicken broth while whisking, followed by the milk.
- Flavor sauce. Stir in the diced tomatoes, green chilies, and all the seasonings, then keep whisking until the sauce thickens and starts to simmer.
- Stir in sour cream. Take the skillet off the heat, add the sour cream, and whisk until smooth. Scoop out 1½ cups of the sauce into a separate bowl and set it aside for the topping.
- Add chicken and corn. Stir the shredded chicken and frozen corn into the sauce in the skillet until everything is evenly coated.
- Spread chicken mixture. Spread half of the chicken mixture across the bottom of the baking dish.
- Add cheese. Sprinkle ⅓ of the cheese over the chicken mixture.
- Layer tortillas. Arrange half of the tortilla pieces over the cheese in an even layer.
- Finish layering. Top with the rest of the chicken mixture and another ⅓ of the cheese, then add the remaining tortillas. Spoon the reserved sauce over the tortillas and finish with the last ⅓ of the cheese.
- Bake until bubbly. Bake for about 30 minutes, until the edges are bubbling and the cheese has melted and started to brown very slightly.
- Rest and garnish. Let the casserole sit for 10 to 15 minutes so the layers can set. Top with chopped cilantro, sliced avocado, and a dollop of sour cream, if you like.
Recipe FAQ’s
Too many tortillas is the usual cause, so stick to the 12 in the recipe and spread them in an even layer. Letting the casserole rest for 10 to 15 minutes before serving helps the layers set.
Yes, sturdy tortilla chips work in a pinch. The layers will be a little less tender, but they still soak up the sauce.
A typical rotisserie chicken gives you more than the 3 cups of shredded chicken this recipe calls for. Save the extra for another meal.
Keep leftovers in an airtight container in the fridge for up to 3 to 4 days. I don’t think this one freezes well, so I’d recommend enjoying it within a few days of baking.
Yes, you can assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours. Bake it straight from the fridge, adding a few extra minutes so the center heats through.
Tips for Success
- Cut the tortillas and grate the cheese before you start cooking, since the sauce comes together quickly once the flour goes in.
- Grate your own cheese if you can, because freshly grated sharp cheddar melts into a smoother, creamier layer than the pre-shredded kind.
- Whisk the flour into the melted butter for a full 1 to 2 minutes before adding any liquid, then pour the broth in slowly while whisking so the sauce stays smooth and free of lumps.
- Take the skillet off the heat before stirring in the sour cream, which keeps the sauce silky instead of separating.
What to Serve with King Ranch Chicken
King Ranch Chicken is rich and creamy, so it goes well with sides that taste fresh, bright, or a little tangy. A simple green salad is my go-to, adding a crisp, refreshing contrast to all those melty layers.
If you’re going all in on a Tex-Mex spread, add a scoop of Mexican Rice and a bowl of Instant Pot Refried Beans. And a big bowl of chips with my Homemade Guacamole and Pico de Gallo keeps the table fresh and fun.
Substitutions and Variations
- Swap the shredded chicken for shredded pork or taco meat, which both pair well with the cumin and chili powder in the sauce. You could also use leftover turkey during the holidays.
- Stir a drained can of black beans in with the chicken and corn for a heartier casserole.
- Stir ¼ cup of chopped fresh cilantro and a squeeze of lime juice into the sauce right before layering to lean into more Mexican-style flavors.
- Swap the smoked paprika for ¼ teaspoon of chipotle powder to give the sauce a deeper, smokier flavor.
