Creamy King Ranch Chicken Casserole Recipe
While there are various versions of this casserole today, the traditional recipe consists of cooked chicken (typically shredded or diced), cream of chicken or cream of mushroom soup, canned tomatoes with green chiles, and a variety of spices. The mixture is layered with cheese and tortillas before being baked until hot and bubbly.
This casserole is an ideal comfort food dish that can feed a crowd; it’s also perfect for potlucks and family get-togethers.

How to Make King Ranch Chicken Casserole
- Prepare: Coat a 9 x 13 baking dish with cooking spray and preheat your oven to 350ºF.
- Cook the onions and pepper: Heat the vegetable oil in a large skillet set over medium-high heat. Once the oil is shimmering, add the onion and bell pepper. Cook for 7 to 8 minutes, or until softened.
- Finish the sauce and chicken: Reduce the heat to low, then stir in the chicken, soup, Rotel, garlic powder, and onion powder. Cook until everything is heated through, about 4 minutes. Remove from the heat and stir in the sour cream and cilantro.
- Assemble: Arrange half of the tortillas on the bottom of the baking dish, followed by half of the chicken mixture and half of the shredded cheese. Repeat with another layer of the tortillas and chicken, ending with the remaining cheese.
- Cook: Bake your King Ranch Chicken Casserole for 30 to 35 minutes, or until heated through and the cheese is completely melted. Let rest for 5 minutes, then serve.
Want to add some crunch on top? Add Fritos, tortilla chips, or ranch Doritos. It’s not traditional, but it is delicious!
