Ingredients You’ll Need

1 ½ pounds boneless skinless chicken breasts: The star of the show! Chicken breasts keep the casserole tender. You can substitute with thighs for a richer flavor.
½ cup chicken broth: This adds moisture and depth to the dish. Vegetable broth works well for a vegetarian option.
1 medium onion, diced: Provides a savory base flavor that enhances each bite. Yellow or white onions are typically used.
10 oz. can Rotel tomatoes: These tomatoes with diced green chilies give a subtle kick. You can also use regular diced tomatoes if you prefer less spice.
1 tsp. cumin: A warm, earthy spice that brings a unique depth to the dish. Skip it if you’re not a fan, or try it with taco seasoning for a twist!
1 tsp. chili powder: Adds a delightful warmth and a hint of heat. Adjust according to your taste preferences.
½ tsp. garlic powder: For a hint of garlic without the fuss of fresh garlic. Fresh garlic can be used if you prefer.
½ tsp. oregano: Herbaceous and aromatic, oregano provides an Italian touch.
1 tsp. salt: Essential for enhancing all the flavors. Adjust according to your dietary needs.
½ tsp. black pepper: A must-have for seasoning that adds subtle heat.
1 cup heavy cream: For that luscious and creamy texture. If you’re cutting calories, you can use half-and-half.
1 ½ Tbsp. cornstarch: Helps thicken the mixture, giving it the ideal consistency.
8-10 corn tortillas, torn into pieces: These form the comforting layers. Flour tortillas can be used in a pinch, but corn adds authentic flavor.
2 cups shredded cheddar cheese: The gooey finish that everyone loves! Feel free to mix in Monterey Jack for extra creaminess.
Sour cream, for topping: Adds a tasty tang and balances the flavors.
Fresh cilantro, for garnish: Brightens up the dish and adds a refreshing herbal note.
Lime wedges, for serving: A squeeze of lime zests up the entire meal.

How to Make King Ranch Chicken Casserole

Place the Chicken: Begin by placing the 1 ½ pounds of boneless skinless chicken breasts in the slow cooker. Evenly sprinkle the 1 diced medium onion over the top for that aromatic base.
Add the Flavors: Pour in the ½ cup chicken broth, then sprinkle in the cumin, chili powder, garlic powder, oregano, salt, and black pepper. Next, add the 10 oz. can of Rotel tomatoes with the juices. Gently stir the mixture to combine.
Slow Cook: Cover the slow cooker and cook on LOW for 6 hours or HIGH for 4 hours. You’ll know it’s done when the chicken is tender and shreds easily.
Shred the Chicken: Once cooked, take the chicken out of the slow cooker and shred it using two forks. Return the shredded chicken back into the slow cooker for that extra flavor boost.
Prepare the Cream Mixture: In a small bowl, whisk together 1 cup of heavy cream and 1 ½ Tbsp. cornstarch until it’s smooth. This step is key for achieving the perfect creamy texture without lumps.
Mix in Tortillas and Cheese: Slowly stir the cream mixture into the slow cooker, followed by the torn pieces of corn tortillas and 2 cups of shredded cheddar cheese. Mix everything well.
Final Cook: Cover the slow cooker again and let it cook on HIGH for about 20-30 minutes, or until the cheese is fully melted and everything is bubbly. Your delicious casserole is ready to serve!

Storing & Reheating

Store any leftovers in an airtight container at room temperature for up to 2 hours, or in the refrigerator for up to 3 days. For longer-term storage, freeze King Ranch Chicken Casserole in a freezer-safe container for up to 3 months. To reheat, simply thaw in the refrigerator overnight, then pop it in the oven at 350°F until heated through, about 20-25 minutes. While the texture remains good, it may be a bit less creamy upon reheating, so consider adding a splash of cream or broth to refresh it.

Chef’s Helpful Tips

Make sure the chicken is completely cooked before shredding to ensure the best texture.
Use room temperature heavy cream for a smoother mixture when blending with cornstarch—this helps prevent lumps.
If you prefer a spicier dish, use hot Rotel tomatoes or add jalapeños.
For a presentation that wows, sprinkle extra cheese and diced fresh cilantro on top before serving.
This dish can be made ahead of time; just add a little extra cook time if cooking from cold.
