My friend, Stephanie, introduced King Ranch Chicken to me years ago. It is a Texas staple, which is where she is from. Over the years, I altered the recipe and this is my updated version. I also call it Cheesy Chicken Dorito Casserole now so there is less confusion about what is actually in the dish.
There are many variations of king ranch casserole recipes. Some use tortillas instead of chips. Some are as simple as 5 ingredients and no layers. My recipe is easy and delicious with loads of cheesy chicken layers! Gather these ingredients:
Grocery List for Dorito Casserole:
- Rotisserie chicken (or 3 cups shredded)
- Doritos chips (we prefer Cool Ranch)
- Sharp cheddar cheese (2 cups shredded)
- Sour cream (1/4 cup)
- Yellow onion (1 small)
- Bell pepper (1 any color)
- Garlic cloves (2)
- RoTel (1 can)
- Cream of mushroom soup (1 can)
- Cream of chicken soup (1 can)
- Chicken broth (1/2 cup)

We prefer Cool Ranch flavor Doritos for this recipe, but traditionally people use nacho cheese flavor. You can also use leftover Thanksgiving turkey for this recipe, so make sure you bookmark this for the holidays!

How to Make Shredded Chicken
I typically always have cooked shredded chicken on hand to use in recipes like this. Once per month, I either boil chicken or use my Crock Pot to cook the chicken then shred it and portion into freezer bags. When I want to make dinners like Chicken Pot Pie, Poppyseed Chicken, Chicken ‘n Dumplings, or Chicken Rice Green Bean Casserole, I can easily grab a bag from the freezer!
I have a few appetizer recipes that use shredded chicken, too! Like this Buffalo Chicken Dip, Egg Rolls, and Buffalo Chicken Bites. And don’t forget you can make chicken salad sandwiches in a jiffy when you have shredded chicken on hand!
Storing and reheating leftovers
Any leftovers of this chicken casserole should be stored covered in the refrigerator for up to 1 week. This casserole is best reheated in the oven in order to crisp up the Doritos again. The microwave is fine, but oven is better.
To make this into a freezer meal, I suggest replacing the Doritos with flour or corn tortillas. Prepare all the layers in a foil casserole dish, cover tightly with plastic wrap and cover again with foil. Store in the freezer until ready to bake. To bake, remove the plastic covering and cover with foil. Bake, covered, for 30 minutes then remove foil and continue to bake until bubbly and crispy.
For your picky eaters who may not like seeing diced tomatoes, green pieces, and onions in their food — try pureeing the sauce in a blender before layering in the casserole dish. This will blend all those questionable ingredients for your picky eaters and they won’t even know they’re eating those yummy veggies!
