This is the best of the BEST! Chicken, tostada shells, peppers, tomatoes and ooey-gooey cheese. It should top the list of Best Comfort Foods. It will make your day better!

If you are from Texas or anywhere in the South you are likely familiar with this dish…because you will find it everywhere! Every gathering, every potluck. And with good reason! This recipe is a KEEPER!

This casserole has been around since the 1950’s and the origins are unclear. Some say it’s named after the country’s biggest ranch, King Ranch…which happens to be located in Texas. BUT, that’s it…they have never claimed the recipe. So, who knows? AND, who cares?

The original recipe used cream of chicken and cream of mushroom soup…but this updated version is SO GOOD! It was also made with corn tortillas and I instead use tostada shells.

I also like to use rotisserie chicken and the average grocery-store roasted chicken is the perfect amount for this recipe. But, use any leftover chicken…or cook some up!


Start by melting butter in a saucepan and sauté onion, green & red peppers and the diced jalapeno.

When the peppers and onion are soft, throw in garlic, chili powder, cumin, salt and pepper and let that cook for a bit.

Sprinkle the flour over the peppers and mix well. Cook and stir for a good minute.

Turn the heat to HIGH and pour in the chicken broth. Cook and stir until the sauce bubbles and thickens. Remove from heat.

Add the Rotel tomatoes, green chilis and sour cream…stir it up and look at the lovely sauce you made!

In a separate bowl, combine the chicken and chopped cilantro.

Pour the sauce over the chicken and mix together. Salt and pepper to taste.

Now you can build the casserole!

Spray the baking dish with cooking spray…

Break up 6-8 tostada shells and spread across pan.

Spoon on half of the chicken and about a third of the grated cheese.

Then another layer of tostada shells, chicken and cheese.

Then another layer of broken tostada shells and top with 8 slices of pepper jack cheese,

Sprinkle with the remaining cheddar and throw it in the oven.

When it’s done baking let it sit for 10 minutes and top with cilantro leaves.
