Ingredients You’ll Need

You’ll need the following ingredients to make this recipe for king ranch chicken.

  • Butter – Butter makes it richer, but you can use olive oil if you prefer.
  • Bell Peppers – You can use any color you prefer.
  • Onion – We use either white or yellow onions.
  • Condensed Soups – We make it using both Condensed Cream of Chicken Soup and  Condensed Cream of Mushroom Soup, but you could use more Cream of Chicken Soup instead of Cream of Mushroom if you prefer or have an allergy.
  • Diced Tomatoes and Chilies – You don’t need to drain the can. We typically use Rotel since it is our favorite.
  • Chicken Breast – You can use rotisserie or another cooked chicken breast.
  • Flour Tortillas – You can use your favorite brand.
  • Cheddar Cheese – If you prefer, you can use another cheese like monterey jack or other similar cheeses.

How Do You Make King Ranch Chicken From Scratch? 

Step 1 – Preheat the oven to 325°F. As it heats, melt the butter in a saucepan over medium heat and then add the peppers and onions. You’ll need to cook them for about 2 to 3 minutes or until they begin to soften.

Step 2 – Mix in the soups and other ingredients. Once the onions and peppers are ready, mix in the Cream of Mushroom soup, Cream of Chicken soup, diced tomatoes & chilies, and chicken.

Step 3 – Assemble and bake. First, spray a 13 x 9 inch casserole dish with cooking spray. Once the pan is ready, add1/3 of tortilla strips to the bottom of the dish, followed by 1/3 of the chicken and soup mixture, and then 1 cup of cheese. Repeat the layers two more times with the final layer being cheese.

Finally, bake uncovered for 30 to 40 minutes or until it is hot and bubbly. Serve fresh from the oven when your favorite veggies or other sides.

Why is it Called King Ranch Chicken? 

Oddly enough, no one knows much about the actual origins of the casserole. All anyone knows is that it gets its name from King Ranch, the largest ranch in the United States. But the real kicker is that it actually has no connection to the ranch and the origin of the Tex-Mex style casserole is a bit of a mystery.

What Chicken Should I Use? 

The easiest and fastest option is to keep some cooked chicken on hand and ready to go. When we make our  Crock Pot shredded chicken or Instant Pot shredded chicken, we always make a big batch of it. This way, we can make some sandwiches or dinner and keep some in the freezer for other recipes.

When we run out or haven’t made them in a while, we’ll either saute some chicken in a skillet with a little salt and pepper or if you’re trying to save time you use a store-bought rotisserie chicken or canned chicken. These are all great options when you just want to throw together a casserole at the last minute.

How Do You Reheat King Ranch Chicken?

You can reheat leftovers a couple of ways.

If you are looking for a leftover dinner for the whole family, the easiest way is to place the whole casserole back in the oven set at 300 degrees. It will need to heat for several minutes or until it has warmed through. 

When you are looking for a single serving, you can scoop some out and place it in a microwave safe bowl or dish. We recommend covering it and cooking for about 2 to 3 minutes or until warmed through.
