This easy Chicken Enchilada Casserole has layers of corn tortillas, shredded chicken, black beans, corn, roasted peppers, enchilada sauce, and melted cheese. It has all the flavors of traditional enchiladas without the work of rolling each one.

As a busy mom of five, I love dinners that I can assemble quickly and know my family will enjoy. This casserole is especially convenient because I can use leftover or rotisserie chicken and prepare the entire dish ahead of time.
As a certified nutrition coach, I also appreciate that the chicken and black beans provide protein, while the corn, beans, and peppers add fiber, making every serving more satisfying. I was inspired to make this dish from my chicken enchilada soup, and I wanted to keep it simple with as few ingredients as possible.
Recipe Overview
Key Ingredients
Here are the key ingredients to make this casserole. Full measurements are listed further down in the recipe card.

- Cooked chicken: Rotisserie chicken makes this especially quick, but any leftover cooked and shredded chicken works.
- Corn tortillas: These create the layers and give the casserole its classic enchilada flavor. Cut them in half to cover the baking dish more evenly.
- Red enchilada sauce: Use a sauce with a flavor and heat level your family enjoys.
- Black beans: They add texture, fiber, and plant-based protein.
- Corn: Fresh, frozen, or well-drained canned corn will work.
- Roasted red peppers: These add a slightly sweet and smoky flavor. Drain them thoroughly to keep the casserole from getting watery.
- Cheddar cheese: Freshly grated cheese melts more smoothly, but you can also use a Mexican cheese blend, Monterey Jack, or Pepper Jack.
How to Make Chicken Enchilada Casserole
Prepare the dish: Preheat the oven to 350°F and coat a 9-by-13-inch baking dish with cooking spray.
Make the chicken mixture: Combine the shredded chicken with 1 cup of cheese and the enchilada sauce in a large bowl.

Create the first layer: Arrange one-third of the tortillas over the bottom of the dish. Add one-third of the chicken mixture, followed by one-third of the black beans, corn, and roasted red peppers.
Repeat the layers: Repeat the layers twice more, using all the tortillas, chicken mixture, beans, corn, and peppers.
Add the cheese: Sprinkle the remaining cup of cheese evenly over the top.

Bake: Cover with foil and bake for 30 minutes. Remove the foil and bake for another 5 to 10 minutes, until the cheese melts and the casserole bubbles around the edges.
Rest and serve: Allow it to rest for 5 to 10 minutes before slicing. Add your favorite toppings and serve.
Assemble the casserole: Layer a few tortillas into the prepared baking dish. Spread a third of the meat mixture, then sprinkle with beans, corn, and red peppers. Repeat until you use all the ingredients, then sprinkle with the remaining cup of cheese.

Recipes Tips
- Drain the beans, corn, and roasted peppers very well. Excess liquid can make the casserole watery.
- Cut the tortillas in half so you can arrange them around the edges of the baking dish without leaving large gaps.
- Grate the cheese from a block when possible. It melts more smoothly than packaged shredded cheese.
- Choose a mild enchilada sauce for children or a medium or hot sauce for more heat.
- Let the casserole rest before cutting it. This helps the layers hold together when served.
- If using frozen corn, thaw it and pat away any excess moisture first.
- Avoid using cold chicken straight from the refrigerator if you want the casserole to heat faster and more evenly.
Common Questions
Yes. Rotisserie chicken is one of the easiest options for this casserole. Remove the skin and shred or chop the meat before measuring.
Yes, but the finished texture will be softer. Corn tortillas hold up well between the layers and give the casserole a more traditional enchilada flavor.
The beans, corn, or roasted peppers may not be fully drained. Allowing the casserole to rest for 5 to 10 minutes after baking also helps the layers set.
Yes. You can replace the red enchilada sauce with the same amount of green enchilada sauce.
One serving is approximately one-eighth of the casserole, or about 1¼ cups. This recipe makes eight generous servings. Add a salad or vegetables on the side for a complete meal.

Easy Variations
- Change the protein: Replace the chicken with cooked ground turkey, lean ground beef, or shredded turkey.
- Add more vegetables: Try sautéed onions, spinach, zucchini, poblano peppers, or diced green chiles.
- Use green enchilada sauce for a brighter, slightly tangier flavor.
- Make it spicier by adding Pepper Jack cheese, jalapeños, or a pinch of cayenne pepper.
- Make it dairy-free: Use your favorite dairy-free shredded cheese.
- Make it gluten-free: Use certified gluten-free corn tortillas and check the enchilada sauce label.
Make ahead, Storage, and Freezing
Make ahead: Assemble the casserole up to 12 hours in advance, cover it tightly, and refrigerate. Let the baking dish sit at room temperature while the oven preheats. It may need an additional 10-15 minutes in the oven.
Storage: Store leftovers in an airtight container in the refrigerator for 3 to 4 days. Reheat individual servings in the microwave or cover and warm them in a 350°F oven.
Freezing: Assemble the casserole in a freezer-safe baking dish, then freeze without baking. Wrap it tightly and freeze for up to 3 months. Thaw it overnight in the refrigerator before baking as directed, adding extra time as needed.
You can also freeze individual cooked portions. Thaw them overnight in the refrigerator and reheat until hot throughout.
