How to Make King Ranch Chicken

If you’re unfamiliar with King Ranch Chicken, it’s traditionally a mixture of cream of mushroom and cream of chicken soup, bell pepper and onion, RO-TEL, and chicken. The biggest difference between King Ranch chicken recipes and this version is the inclusion of Greek yogurt and fresh mushrooms instead of the condensed soups.

This gives you the creaminess with a fraction of the fat and calories!

To make it, you’ll need to dice an onion and bell pepper, chop some mushrooms, and mince a little garlic. Then cook the pepper, onion, and mushrooms for 6-8 minutes to soften before adding garlic, spices, and a can of diced tomatoes and chilies.

While the veggies are cooking, shred a rotisserie chicken (or use another Mexican chicken recipe) to go in the pan with Greek yogurt. Stir everything together and you’re ready to assemble the King Ranch chicken casserole.

While I used a cast iron skillet, any large baking dish should work fine. I opted to leave the tortillas whole and overlap them but if you’re working with a different dish, you can tear them into pieces like some traditional King Ranch chicken recipes.

This part of the recipe is simple—divide the chicken mixture and shredded cheddar in half and create two layers with tortillas in the middle. Then you’re ready to bake!

Different baking dishes may affect cook time slightly, but you don’t have to be all that concerned with precise cook times. As long as the cheese fully melts, you’re pretty much good to go.

Ingredient Modification Notes

I’ll run through a few ingredient questions I foresee coming up.

Can I omit the mushrooms?

Sure. You can omit just about anything in this recipe, but the volume of the filling will be affected. If you get to omission crazy, your King Ranch chicken casserole may look a little flat and sad.

How can I substitute for rotisserie chicken?

Here’s a handful of chicken recipes you could use instead of rotisserie chicken:

You can also use cubed chicken or other precooked variations of chicken for your King Ranch chicken casserole.

Is this recipe spicy?

Not at all. If you want a spicier chicken casserole, add a bit of cayenne pepper or crushed chipotle pepper like my Nashville Hot chicken burgers.

You could also use taco seasoning in place of the spices if you’re working with a minimal kitchen.

How can I make this recipe dairy free? 

For the creaminess in the filling a chickpea or veggie puree would probably do the job. You could also use a vegan cream cheese, as those are readily available these days.

The trickier substitution will be the cheddar for melting. If you can find a vegan cheese that melts well, I’d start there. Beyond that, I’m short on ideas.

Final Notes for Healthy King Ranch Chicken Casserole

If you’d like an extra creamy chicken casserole (read: running everywhere when you cut into it), you can increase the amount of Greek yogurt. I bet you could double the yogurt without any issues.

The base recipe doesn’t call for any salt and pepper, so be sure to add to taste at the end.

Are you supposed to drain the tomatoes with chilis or leave the liquid?

My skillet wasn't big enough to mix the Greek yogurt in after cooking everything so I transferred it to a bowl and mixed it. And I didn't have any circular baking dish to use so I just used a rectangular one. I loved how it turned out! So good!!

***** Delicious! Haven't made King Ranch Chicken since I stopped using cream canned soups years ago. This was a tasty version. I used the pineapple chipotle crockpot chicken recipe from this website for the meat. I did add more Greek yogurt since I didn't want it too dry....but that addition wasn't necessary at all. Since I only had mild Ro-tel, I did add a heaping tablespoon of fresh minced jalapeno for a little kick. The result was not very spicy. If you haven't tried King Ranch Chicken before, just a head's up that the corn tortilla flavor does come through. Thanks for another keeper recipe.

This is delish! I add a jalapeño to it to spice it up. And hot sauce on top when serving it! Otherwise, it’s perfect and flavorful!
