Ingredients You’ll Need
Every ingredient in this Easy King Ranch Chicken Casserole Recipe plays a crucial role in creating its signature flavor and texture. From the creamy soups that add luxurious moisture to the corn tortillas that give just the right amount of body, each element is simple yet essential.
- 3 cups cooked, shredded chicken: The hearty star protein that soaks up all the savory flavors perfectly.
- 1 can (10.5 oz) cream of chicken soup: Adds a rich creaminess and depth to the casserole base.
- 1 can (10.5 oz) cream of mushroom soup: Balances the dish with its earthy undertones and luscious texture.
- 1 can (10 oz) diced tomatoes with green chilies (like Rotel), undrained: Brings a zesty kick and vibrant color that livens up every bite.
- 1 teaspoon chili powder: Infuses the mix with a subtle but warming spice.
- 1/2 teaspoon cumin: Provides a smoky, slightly nutty flavor that complements the chilies beautifully.
- 1/2 teaspoon garlic powder: Enhances the savory profile with a gentle garlic hit.
- 1 small onion, diced: Sautéed until translucent for that sweet, mellow base layer of flavor.
- 2 cups shredded cheddar cheese: Melts into a bubbly, golden topping that’s simply irresistible.
- 10 small corn tortillas, torn into pieces: Offer a soft, comforting texture and a subtle corn flavor that holds the casserole together.
- 2 tablespoons vegetable oil (for sautéing): Helps cook the onions to perfection without overpowering their natural sweetness.
How to Make Easy King Ranch Chicken Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). This sets the stage for perfect baking. Grease a 9×13-inch casserole dish generously so nothing sticks and cleanup is a breeze.
Step 2: Sauté the Onion
Heat the two tablespoons of vegetable oil in a skillet over medium heat. Add the diced onion and cook until it becomes translucent, which should take about 4 to 5 minutes. This simple step unlocks the onion’s natural sweetness and forms a flavorful base for the casserole.
Step 3: Mix the Sauce Base
In a large mixing bowl, combine the sautéed onions, cream of chicken soup, cream of mushroom soup, and the entire can of diced tomatoes with green chilies, including the juice. Stir in the chili powder, cumin, and garlic powder. Mixing all these ingredients now ensures a harmonious blend of creamy and spicy notes.
Step 4: Add the Chicken
Toss the shredded chicken into the soup mixture and stir until every bit of chicken is coated with that creamy, flavorful sauce. This step is key to distributing the flavors evenly throughout the casserole.
Step 5: Layer the Casserole
Place half of the torn corn tortillas in the bottom of your greased casserole dish. Follow with half of the chicken and sauce mixture, then sprinkle 1 cup of cheddar cheese over the top. Repeat these layers with the remaining tortillas, chicken mixture, and finish with the last cup of cheese. Layering like this creates bursts of cheesy, saucy goodness in every forkful.
Step 6: Bake
Cover the casserole with foil and bake for 25 minutes. Then, remove the foil and allow it to bake for another 10 minutes or until the cheese is delightfully bubbly and slightly golden. This baking time melds the flavors and ensures the tortillas soften perfectly.
Step 7: Rest and Serve
Once out of the oven, let the casserole rest for about 5 minutes. This helps it set slightly, making it easier to cut and serve. If you’d like, garnish with chopped fresh cilantro or green onions for a bright, fresh contrast.

Garnishes
A sprinkle of chopped cilantro or sliced green onions adds a perfect fresh touch and pops of color to your casserole. You can even add a dollop of sour cream or a few slices of avocado for a creamy, cool contrast to the warm, spicy casserole.
Side Dishes
This casserole pairs wonderfully with crisp green salads or steamed vegetables like broccoli or green beans to balance out the richness. You could also serve it alongside some Spanish rice or refried beans if you want to lean into the Tex-Mex vibe.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins or small, oven-safe bowls to make it feel a bit more special and personalized. You could also turn it into a layered dip for parties by spooning it into a deep dish and serving with tortilla chips on the side.
Make Ahead and Storage
Storing Leftovers

Freezing
This casserole freezes beautifully! After baking and cooling completely, cover tightly with foil and plastic wrap, then freeze for up to 2 months. To reheat, thaw overnight in the refrigerator before warming it up.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through, about 20–25 minutes. Alternatively, microwave portions on medium power to avoid drying out the cheese topping.
FAQs
Can I use rotisserie chicken for this casserole?
Absolutely! Rotisserie chicken is perfect because it’s already cooked and shredded, which saves time and adds extra flavor.
What can I substitute for cream of chicken and cream of mushroom soups?
If you prefer homemade or allergen-free options, you can make a simple white sauce with butter, flour, milk, and seasoning to replace the canned soups.
Is there a vegetarian version of this recipe?
Yes! Simply swap the chicken for sautéed vegetables like bell peppers, zucchini, and mushrooms for a delicious veggie-packed casserole.
Can I use flour tortillas instead of corn tortillas?
While corn tortillas are traditional and provide authentic texture, flour tortillas can work if that’s what you have on hand—just keep in mind the final texture will be a bit different.
How spicy is this casserole?
The diced tomatoes with green chilies add a mild to medium kick, but you can adjust the heat by selecting mild or hot diced tomatoes and by tweaking the chili powder amount to your taste.
