Crock Pot King Ranch Chicken is best served with a simple side like oven roasted green beans but save room for mini cheesecakes for dessert!
You guys love crock pot chicken recipes. I hear you and I have a new one for you. These end of summer days where you don’t feel like turning on the oven, slow cooker chicken meals are my favorite.
WHAT IS KING RANCH CHICKEN?
The history of this chicken casserole is much debated and often thought to have been created in the famous King Ranch in South Texas. Although a popular Tex-Mex dish, this easy dinner casserole has no connection to the largest ranch in the US.
The ingredients, such as Ro-Tel, green pepper, chili powder, and corn tortillas, give this slow cooker casserole a great flavor that is similar to many dishes found in South Texas.
Traditional King Ranch Chicken is made in a casserole dish and baked to bubbly perfection. This slow cooker version keeps all the flavor of the original but with the added benefit of being made in the slow cooker.
To mimic the baked version, remove the slow cooker lid for the last 30 minutes of cooking.

INGREDIENTS
Cooked chicken – The beauty of this recipe is that you can use leftover chicken or a rotisserie from the store. Both are a total time saver come dinner time. If you don’t have leftovers, I often make instant pot shredded chicken.
Onion – Any type of onion will work in this recipe, although I prefer to use white.
Green pepper – Fun fact: male peppers have 3 bumps and females have 4 bumps.
Cream of Onion Soup – Or cream of chicken or mushroom. Use what you like or make homemade “cream of” soup.
Ro-Tel – I get the mild version but feel free to grab a spicier version of Ro-Tel if that’s what you like.
Chili Powder – For a little kick.
Minced Garlic – I always keep jarred minced garlic on hand. Fresh works too, of course.
Corn Tortillas – Flour tortillas will not work well in this casserole since they absorb more moisture than corn.
Shredded Cheddar – I used a mild cheddar but use what you like.
HOW TO MAKE CROCK POT KING RANCH CHICKEN
The great about this slow cooker recipe is that the prep is easy and can even be done the night before. To start, you want to prep your vegetables and chicken.
Chop your onion and green pepper and then shred or dice your cooked chicken. Like I said, this could be done the night before and stored in the fridge until assembly time.
You can spray your slow cooker with cooking spray or even use a crock pot liner for easy clean up.
Slice your corn tortillas into approximately 1″ pieces. A pizza cutter worked beautifully for this, or just tear them.
Mix together the prepped vegetables and chicken, the cream of onion soup, Ro-Tel, chili powder, garlic, and some of your cheese in a large bowl.
Next, it’s time to assemble the King Ranch chicken. You want to place tortillas on the bottom of your slow cooker, add in some of the casserole mixture, place tortillas on top of the casserole mixture and repeat. You will layer the casserole in thirds and top with remaining cheese.
Cover and cook on LOW for 3 1/2 hours. The edges should be bubbly and golden. Then, remove the lid and cook for another 30 minutes. This will give the casserole an oven baked taste and texture.
