King ranch chicken casserole is my absolute favorite Tex-Mex-inspired dish to bring to potlucks. My king ranch chicken casserole recipe is made with all fresh ingredients– no Velveeta or canned soups here! It’s creamy, cheesy, and so delicious with none of the bad stuff. I could never get tired of how delicious this recipe is, and it’s pretty nostalgic too, so it’s the definition of comfort food.
My king ranch chicken casserole recipe is filled with all the best ingredients, like chicken, cheese, sour cream, green chiles and tomatoes, peppers, onions, and more. And I skipped the cream of mushroom soup and Velveeta that it’s usually made with. It takes a few extra steps, but it’s totally worth it for this creamy, flavorful casserole.

Tips for Success
- If I don’t have leftover chicken lying around, I’ll use a rotisserie chicken from the store.
- To make ahead, follow the recipe without baking it, and then freeze it until you’re ready to reheat and eat. You could also store it in the refrigerator for a couple of days, then grab it and bake it when it’s time for dinner.
How to Store and Reheat
Store leftover king ranch chicken casserole tightly covered in the refrigerator for up to 3 days or in the freezer for up to 1 month. When you’re ready to reheat it, you can either let it thaw overnight in the refrigerator and cook according to the instructions or bake it straight from frozen for 45-60 minutes.
Serving Suggestions
This king ranch chicken casserole is a hefty meal all on its own, but it’s also great paired with a light cucumber onion salad or my favorite spinach salad with bacon. Both are great options to get some extra fruit and veggies in.

Hi question on the cheese quantity? It says 2 cups 8 oz. 2 cups is 16oz. Not 8. Not sure if I should buy a total of 32 oz or a total of 16 oz?
Hi Alex, when shredded, 8 ounces of cheese comes out to about 2 cups!
I don’t see where you have the number of servings included anywhere. Usually casseroles in a 9×13 dish are 6 to 8. Is that what you would suggest?
Hi Kim, this recipe serves 8!
Do the tortilla chips get soggy?
The tortilla chips on the bottom and in the center soften, but the ones on top stay crispy!
Excellent recipe! Very fresh with just the right about of spice. I added a bit more lime juice…. that along with fresh chopped cilantro gave it a real pop of wow.
Thank you!
Thanks for sharing your process!
