Let’s be honest—nobody has time to fuss over dinner every night. That’s why I love this Chicken Enchilada Casserole. It’s a one-dish wonder that combines shredded chicken, beans, corn, and a medley of spices, all enveloped in a rich enchilada sauce and topped with bubbling cheese.

I remember the first time I whipped this Chicken Enchilada Casserole, it was a game-changer for busy weeknights. All the delicious layers of chicken, black beans, corn, and melty cheese all smothered in rich enchilada sauce come together in a way that feels both comforting and exciting. Plus, the best part? Minimal cleanup! It’s the perfect dish to share with family or impress your friends without breaking a sweat in the kitchen.

Before You Begin
- Prepare All Ingredients First: Gather and measure out all your ingredients before you begin. That’s the hardest part of making this casserole. Once that’s done, simply assemble and bake.
- Choose the Right Enchilada Sauce: Whether you prefer store-bought or homemade, selecting a quality enchilada sauce can make a big difference in flavor. Taste it beforehand and adjust seasoning if needed to match your spice preference.
- Layer Thoughtfully: When assembling the casserole, layer ingredients in a way that each bite gets a bit of everything. Start with sauce, then tortillas, filling, and cheese to ensure every component melds together beautifully.
- Let It Rest Before Serving: Allowing the casserole to cool for a few minutes after baking helps it set, making it easier to serve.

Ingredients You’ll Need
- Chicken: You’ll need cooked chicken for this recipe. Rotisserie chicken is perfect to use here.
- Enchilada Sauce: You can use store-bought canned sauce or make your own enchilada sauce with my easy recipe.
- Corn Tortillas: Traditionally enchiladas are made with corn tortillas but feel free to use flour tortillas if you prefer.
- Black Beans: For lots of extra protein. Pinto beans or kidney beans are great alternatives.
- Corn: Brings a sweet crunch to the casserole. Fresh or frozen corn can be used instead of canned.
- Diced Green Chilies: For a mild heat and smoky flavor. Fresh diced jalapeños or roasted poblano peppers can be used if you prefer more control over the spice level.
- Spices: I used ground cumin, chili powder, salt and pepper. Feel free to adjust each spice to taste.
- Cheese: Cheddar or Monterey Jack cheese are both great because they melt easily. Other options are Mozzarella or Mexican cheese blend.
First, preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or butter.

In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 small finely chopped onion and sauté until softened, about 5 minutes. Add 3 cups cooked shredded chicken, 1 can (15 ounces) black beans (drained and rinsed), 1 can (15 ounces) corn (drained), and 1 can (4 ounces) diced green chilies to the skillet. Sprinkle in 1 teaspoon ground cumin and 1 teaspoon chili powder. Stir everything together and cook for another 2-3 minutes until heated through.

Spread a thin layer of red enchilada sauce on the bottom of your prepared baking dish. Next, arrange a layer of corn tortillas, cut into quarters, over the sauce. Then, spread half of the chicken mixture evenly over the tortillas, followed by 1 cup shredded cheddar or Monterey Jack cheese.

Add another layer of quartered corn tortillas, followed by the remaining chicken mixture. Pour the remaining red enchilada sauce over the top layer. Finally, sprinkle the remaining 1 cup shredded cheese evenly over the casserole.

Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow the flavors to meld and the tortillas to soften. After 20 minutes, remove the foil and bake for an additional 10 minutes, or until the cheese on top is melted and bubbly. Remove the casserole from the oven and let it cool for a few minutes. Garnish with fresh chopped cilantro. Serve hot with sour cream and sliced avocado on the side, if desired.

Frequently Asked Questions
