Ingredients You’ll Need
This creamy Mexican chicken casserole uses simple, easy-to-find ingredients to create a truly spectacular meal. Here’s what you’ll need:
- Shredded Chicken: Rotisserie chicken works perfectly for a quick option. You can also use any cooked, shredded chicken you have on hand. Check out our recipe for 30-minute baked chicken breast for an easy DIY option.
- Cream Cheese: The key to our signature creamy sauce. Be sure it’s softened to room temperature for easy mixing.
- Sour Cream: Adds a slight tang and contributes to the rich, smooth sauce.
- Enchilada Sauce: Use your favorite red enchilada sauce, either mild or medium heat.
- Corn Tortillas: We find they provide the best texture, but flour tortillas can be substituted.
- Black Beans: Rinsed and drained to remove excess sodium.
- Corn: Canned or frozen corn works great.
- Diced Green Chiles: For a mild, tangy heat.
- Shredded Cheese: A Mexican blend, cheddar, or Monterey Jack are all excellent choices.
- Spices: A simple mix of chili powder, cumin, garlic powder, and onion powder provides the perfect savory flavor.
Step-by-Step Instructions
Making this easy Mexican chicken casserole is a breeze. Just follow these simple steps!
- Preheat and Prep: Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Make the Creamy Sauce: In a large bowl, combine the softened cream cheese, sour cream, enchilada sauce, and spices. Mix until smooth and well-combined.
- Combine Ingredients: Gently fold the shredded chicken, black beans, corn, and diced green chiles into the sauce. Stir until everything is evenly coated.
- Layer the Casserole: Spread a thin layer of the chicken mixture on the bottom of the prepared baking dish. Arrange a single layer of corn tortillas on top, tearing them as needed to cover the surface.
- Repeat Layers: Continue layering the chicken mixture and tortillas until you run out, ending with a final layer of the chicken mixture.
- Add Cheese and Bake: Sprinkle the shredded cheese evenly over the top. Bake for 20-25 minutes, or until the casserole is bubbly and the cheese is melted and golden brown.

Tips for the Best Casserole
To ensure your Mexican chicken casserole is absolutely perfect, follow these simple tips:
- Use Room Temperature Ingredients: Allowing your cream cheese and sour cream to soften makes the sauce much easier to mix and results in a smoother consistency.
- Don’t Overbake: Bake just until the casserole is heated through and the cheese is melted. Overbaking can dry it out.
- Let it Rest: Allow the casserole to rest for 5-10 minutes after removing it from the oven. This helps it set, making it much easier to slice and serve.
Customizations and Variations
This recipe is a fantastic starting point. Feel free to customize it to your heart’s content!
- Add Rice: Mix in 1-2 cups of cooked rice with the chicken mixture to make it even more hearty. This variation is similar to our popular chicken and rice casserole.
- Spice it Up: For more heat, add a diced jalapeño to the mixture or a pinch of cayenne pepper to the sauce.
- Change the Protein: This casserole works wonderfully with shredded beef or ground beef. If you love ground beef dishes, try our keto ground beef casserole.
- Add Veggies: Feel free to add sautéed onions, bell peppers, or spinach to the chicken mixture for extra nutrients.
What to Serve with Your Casserole
This Mexican chicken casserole is a complete meal on its own, but it also pairs wonderfully with a variety of sides. Serve it with a dollop of sour cream, guacamole, or salsa. For a fuller meal, a simple side salad or some Spanish rice would be excellent additions.
Storing and Reheating Leftovers
One of the best things about this casserole is that the leftovers are just as delicious!
- To Store: Cover the baking dish tightly with foil or transfer leftovers to an airtight container. Store in the refrigerator for up to 4 days.
