What is King Ranch Chicken?

King Ranch Chicken Casserole is a popular Texas dish made from layers of chicken, cheese, tortillas and a creamy gravy with peppers and onions. The name references the historic King Ranch in Texas. While many versions use canned soups, this recipe uses a scratch gravy for a fresher, richer flavor that still stays family‑friendly and not overly spicy.

Kitchen Tools

• Large, deep baking dish (13×9 inch preferred)
• Large skillet
• Sharp knife and cutting board
• Tongs or spatula
• Large spoon
• Prep bowls

Ingredients

• 2 large boneless skinless chicken breasts (about 2 cups cooked; use 3 if breasts are small)
• 1 small yellow onion, diced
• 2 bell peppers, assorted colors, diced
• 3 tablespoons all‑purpose flour
• 1 1/4 cups chicken broth
• 2 oz cream cheese
• 4 oz shredded cheddar
• 4 oz shredded Mexican blend cheese
• 1/2 cup sour cream (or plain non‑fat Greek yogurt)
• 1 10‑oz can diced tomatoes with green chilies (Rotel), drained
• 1/2 tablespoon chili powder
• 1 teaspoon ground cumin
• 1/2 teaspoon sea salt
• 1 teaspoon ground black pepper
• 1/4 teaspoon cayenne (optional)
• 3 tablespoons unsalted butter
• 4 cloves garlic, minced
• 15 fajita‑size flour tortillas (or corn tortillas), torn or cut into pieces
• Olive oil for cooking

For serving: diced green onions, cilantro, sliced avocado or sour cream.

Making the Casserole

1. Preheat oven to 400°F. Season chicken breasts with salt, pepper and paprika. Heat a drizzle of olive oil in a large skillet over medium heat and cook chicken about 5 minutes per side, until internal temperature reaches 165°F. Remove and set aside to rest, then shred or chop.
2. In the same skillet, add butter and sauté the diced onion and peppers over medium heat until softened, about 5–7 minutes. Add the minced garlic and cook 30 seconds more.
3. Sprinkle the flour over the veggies and stir to combine. Gradually whisk in the chicken broth and cook until the gravy thickens. Stir in chili powder, cumin, salt, pepper and cayenne if using; adjust seasoning to taste.
4. Fold the drained diced tomatoes, shredded chicken, sour cream, cream cheese and cheddar into the gravy until well combined and thick.
5. Spread a thin layer of the chicken mixture in a 13×9 inch baking pan. Cover with torn tortilla pieces. Repeat layering (mixture, tortillas) three times, finishing with a generous layer of the Mexican blend cheese on top.
6. Bake on the center rack for 25–30 minutes, until bubbly and golden. Let rest a few minutes, then garnish with green onions, cilantro and avocado if desired. Serve warm.

Pro Tips

Save time: Use rotisserie chicken to skip cooking and shredding the breasts. Add it directly to the gravy.

Layering: Tearing tortillas gives bite‑sized pieces throughout; whole tortillas create a more lasagna‑style casserole. Both flour and corn work—choose your preference.

Lighten it up: Swap sour cream for plain non‑fat Greek yogurt to reduce fat while keeping creaminess.
