King Ranch Chicken Casserole

King Ranch Chicken Casserole is a true Texas classic, and after one bite you will understand why it has been on potluck tables for generations. Think of it as chicken enchiladas that you layer instead of roll: soft corn tortillas, tender chicken, a creamy sauce with a little kick, and plenty of melted cheese.

My version builds the sauce from scratch with sautéed peppers and onion, but it still comes together fast thanks to rotisserie chicken. It is easy to make ahead, feeds a crowd, and reheats beautifully.

Ingredients

• 3 cups shredded cooked chicken (1 rotisserie chicken)
• 2 tablespoons butter
• 1 medium onion, diced
• 1 green bell pepper, diced
• 1 red bell pepper, diced
• 3 cloves garlic, minced
• 1 teaspoon chili powder

• 1/2 cup sour cream

Ingredient Notes

How to Make King Ranch Chicken Casserole

1. Prep. Heat the oven to 350°F and grease a 9×13-inch baking dish.
2. Sauté the vegetables. Melt the butter in a large skillet over medium heat. Cook the onion and bell peppers until soft, 6 to 7 minutes. Stir in the garlic, chili powder and cumin for 1 minute.
3. Make the sauce. Stir in both soups, the tomatoes with green chiles, broth and sour cream until smooth. Fold in the shredded chicken.
4. Layer. Spread a thin layer of sauce in the dish. Add one third of the tortilla pieces, one third of the chicken mixture and 1 cup of cheese. Repeat two more times, ending with cheese.
5. Bake. Cover with foil and bake 20 minutes. Uncover and bake 15 minutes more, until bubbling and golden.
6. Rest and serve. Let it rest 10 minutes so it slices cleanly, then top with green onions and cilantro.

Tips for the Best King Ranch Casserole

• Warm the tortillas. 30 seconds in the microwave makes them soft and easy to layer.
• Let it rest. Ten minutes after baking keeps the layers from sliding apart.
• Season the chicken. A pinch of salt and cumin on the chicken adds flavor to every layer.
• Make it ahead. Cover and refrigerate up to 24 hours; add 10 minutes to the covered baking time.

Easy Variations

• From scratch sauce: replace the soups with a homemade white sauce made from butter, flour, broth and milk.
• Spicier: add a diced jalapeño with the peppers and use pepper jack cheese.
• Turkey: perfect for leftover holiday turkey.
• Tortilla chips: use sturdy tortilla chips instead of tortillas for a crunchier top layer.

What to Serve With It

Serve with Mexican rice, black beans, a crisp green salad with lime dressing, or chips with salsa and guacamole.

Storage

• Refrigerator: cover and store for up to 4 days.
• Freezer: freeze baked or unbaked casserole, well wrapped, for up to 3 months. Thaw overnight before baking.
• Reheat: warm covered at 350°F for 20 minutes or microwave single portions.

Frequently Asked Questions

Why is it called King Ranch Chicken?

It is named after the famous King Ranch in Texas, though the dish became popular in Texas home kitchens and church cookbooks rather than on the ranch itself.

Can I use flour tortillas?

You can, but corn tortillas are traditional and keep their texture better. Flour tortillas turn softer.

Is King Ranch Chicken spicy?

It is mild to medium. Most of the heat comes from the tomatoes with green chiles, so choose mild or hot to suit your family.

Can I make it without canned soup?

Yes. Make a simple sauce with 3 tablespoons butter, 3 tablespoons flour, 1 1/2 cups broth and 1 cup milk.
