This King Ranch Casserole is a breeze to make in the slow cooker. Filled with creamy southwest sauce, tender chicken and corn tortillas, it’s a meal you will look forward to.

If you have tried my chicken enchilada casserole, you will love the flavors in the King Ranch Casserole. The only difference is that this one has a decadent southwest sauce instead of enchilada sauce. It is great for feeding a hungry family or for having yummy leftovers in the fridge all week.

Key Ingredients
Chicken: Boneless, skinless breasts that cook tender and shred easily.
Rotel: Brings diced tomatoes, green chiles, and just the right amount of heat..
Corn Tortillas: Are added at the end of the cooking time and pull the casserole together.
Sauce: Heavy cream + cornstarch + spices create a smooth base—no cream soup needed.
Cheddar Cheese: Melts through every layer for that classic, cheesy finish.



How to Make King Ranch Casserole
- Slow cook the seasoned chicken, onion, broth, and Rotel until tender.
- Stir in the creamy mixture, torn tortillas, and cheese.
- Cook until bubbly and serve.

Sarah’s Tips & Variations
Flour Tortillas: I don’t recommend using flour tortillas because they can become sticky or gluey if the casserole sits for too long. Though if you serve individual portions with the filling that works well.
Beef Ranch Casserole: Substitute stew meat for chicken and use beef broth instead.
Extras: Feel free to add a cup of black beans, corn, or sautéed bell peppers to the slow cooker for extra flavor and texture.

How to Serve King Ranch Casserole
Other Serving Options: Serve over tortilla chips or steamed white rice for a twist.
Toppings: We love sour cream, cilantro, chopped tomatoes and green onion (or it’s just fine as is!).
Other Sides: To feed more people, serve with Refried Beans, Spanish Rice, or a green salad.
How to Store & Reheat
Store leftovers in an airtight container in the refrigerator for up to 3-4 days. You can freeze for up to three months.
Reheat in the microwave or on the stovetop over low heat, adding a splash of chicken broth or water if the mixture has thickened too much.
