Few weeknight meals are as satisfying and easy to prepare as a baked casserole. King Ranch Chicken Casserole blends familiar Tex‑Mex flavors into a single, family‑friendly dish that reheats and freezes well. It layers shredded chicken, a rich creamy sauce made from a simple gravy, diced tomatoes with mild chilies, a mix of cheeses and tortillas for a casserole that resembles a Mexican lasagna.

What is King Ranch Chicken?

King Ranch Chicken Casserole is a classic Texan comfort food named after the historic King Ranch. The casserole typically includes cooked chicken, tortillas (flour or corn), cheese and a saucy filling with bell peppers and onions. While some recipes use canned condensed soups, this version uses a homemade gravy made with butter, flour and chicken broth for better flavor and texture. The dish is mild in spice, making it suitable for children, yet easy to adapt for anyone who prefers more heat.

Kitchen Tools

• Large, deep baking dish (13×9 inch recommended)
• Large skillet or sauté pan
• Sharp knife and cutting board
• Tongs or fork for shredding
• Large spoon or spatula
• Prep bowls

Ingredients

• 2 large boneless, skinless chicken breasts (about 2 cups cooked and shredded; use a third breast if small)
• 1 small yellow onion, diced
• 2 bell peppers, assorted colors, seeded and chopped
• 3 tablespoons all‑purpose flour
• 1 1/4 cups chicken broth
• 2 oz cream cheese
• 4 oz shredded cheddar and 4 oz shredded Mexican blend (or substitute pepper jack or mozzarella)
• 1/2 cup sour cream (plain Greek yogurt can be used instead)
• 1 (10 oz) can diced tomatoes with green chilies (drained; use mild or spicy to taste)
• 1/2 tablespoon chili powder, 1 teaspoon ground cumin, 1/2 teaspoon salt, 1 teaspoon ground black pepper, and 1/4 teaspoon cayenne (optional)
• 3 tablespoons unsalted butter and a splash of olive oil
• About 15 fajita‑size tortillas (flour or corn; tear or layer whole as you prefer)
• For serving: diced green onions, cilantro, sliced avocado or guacamole, salsa and extra sour cream

Making the Casserole

1. Preheat the oven to 400°F (200°C). Season both sides of the chicken breasts with salt, pepper and paprika. Heat a skillet with a little olive oil over medium heat and cook the breasts about 5 minutes per side, or until the internal temperature reaches 165°F. Remove and let rest, then shred or chop.
2. In the same skillet, add the butter and sauté the diced onion and bell peppers over medium heat until soft, about 5–7 minutes.
3. Sprinkle the flour over the softened vegetables and stir to coat. Gradually whisk in the chicken broth and cook until the gravy thickens. Stir in cumin, chili powder and cayenne (if using); adjust seasoning to taste.
4. Drain the diced tomatoes with green chilies, then combine them with the gravy, shredded chicken, sour cream, cream cheese and some of the shredded cheddar. Stir until smooth and thick.
5. Spread a thin layer of the chicken mixture in the bottom of a 13×9 inch pan, then add torn or layered tortillas to cover. Repeat to create three layers of sauce and tortillas, finishing with a generous layer of shredded Mexican blend or cheddar on top.
6. Bake on the center rack for 25–30 minutes, until bubbling and the cheese is melted. Let rest a few minutes before slicing. Serve topped with green onions, cilantro and sliced avocado or a dollop of sour cream.

Pro Tips

Save time: Use rotisserie chicken or leftover cooked chicken to skip the initial cooking step and assemble the casserole faster.

Layering options: Tear tortillas for a rustic bite with pieces throughout the dish, or lay whole tortillas for a cleaner, lasagna‑style slice. Corn tortillas work well if you prefer a more traditional flavor.

Make it lighter: Substitute plain non‑fat Greek yogurt for sour cream and use reduced‑fat cheeses to lower calories while keeping creaminess.
