Ingredients List for Mexican Chicken Casserole
Before jumping into the cooking process, here’s a breakdown of everything you need to make a mouth-watering Mexican Chicken Casserole:
- Chicken: 3 cups of shredded cooked chicken (rotisserie chicken works great for convenience)
- Tortillas: 8-10 small corn tortillas, cut into quarters (flour tortillas can be used too)
- Cheese: 2 cups of shredded Mexican blend cheese (cheddar or Monterey Jack also work)
- Sour Cream: 1 cup (adds creaminess to the dish)
- Salsa: 2 cups of your favorite red salsa (medium or mild, depending on your spice tolerance)
- Black Beans: 1 can (15 oz) of black beans, drained and rinsed
- Corn: 1 cup of frozen corn, thawed
- Onion: 1 medium onion, chopped
- Bell Pepper: 1 red or green bell pepper, diced
- Green Chiles: 1 small can (4 oz) of diced green chiles (optional, for extra heat)
- Cumin: 1 teaspoon (adds warmth and depth to the flavor)
- Chili Powder: 1 teaspoon (adds spice and a smoky undertone)
- Garlic: 2 cloves, minced (for extra savory flavor)
- Olive Oil: 2 tablespoons (for sautéing the veggies)
- Chicken Broth: ½ cup (to add moisture)
- Cilantro: Fresh cilantro for garnish (optional but adds a fresh pop of color and flavor)
Substitutions and Variations
This Mexican Chicken Casserole recipe is versatile, meaning you can easily customize it to suit your taste preferences or dietary restrictions. Here are some substitutions and variations to consider:
- Vegetarian Option: Skip the chicken and use extra black beans, pinto beans, or even some sautéed mushrooms to keep it hearty and satisfying.
- Gluten-Free: Be sure to use gluten-free corn tortillas and double-check that all your canned ingredients (like the beans and green chiles) are gluten-free.
- Dairy-Free: Use dairy-free cheese and sour cream alternatives. You can also leave out the cheese entirely if you prefer a lighter dish.
- Spice Level: If you like more heat, opt for a spicier salsa and throw in some jalapeño slices. For a milder version, use a mild salsa and skip the green chiles and chili powder.
- Different Meats: While shredded chicken is classic, you can use ground beef, turkey, or pork for a different twist. Leftover pulled pork also adds a rich, smoky flavor to the casserole.
Step-by-Step Cooking Instructions

Here’s how to make this delicious casserole from scratch:
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Grease a 9x13-inch casserole dish with cooking spray or a little oil to prevent sticking.
Step 2: Cook the Vegetables
In a large skillet, heat the olive oil over medium heat. Add the chopped onion, bell pepper, and garlic. Sauté for 4-5 minutes until softened and fragrant.
Step 3: Combine Chicken and Ingredients
In a large mixing bowl, combine the shredded chicken, sautéed veggies, black beans, corn, green chiles, cumin, chili powder, and salsa. Stir until everything is evenly mixed.
Step 4: Assemble the Casserole
Layer half of the quartered tortillas at the bottom of your greased casserole dish. Then spread half of the chicken mixture over the tortillas. Sprinkle a layer of shredded cheese over the chicken mixture. Repeat with the remaining tortillas, chicken mixture, and cheese.
Step 5: Add Sour Cream and Broth
In a small bowl, mix the sour cream with chicken broth until smooth. Pour this mixture evenly over the casserole to help keep it moist during baking.
Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and bubbly, and the edges are slightly golden.
Step 7: Garnish and Serve
Once the casserole is done, remove it from the oven and let it cool for about 5 minutes. Garnish with fresh cilantro before serving.
How to Cook Mexican Chicken Casserole: A Step-by-Step Guide
- Preheat your oven to 350°F and grease the casserole dish.
- Sauté onions, bell peppers, and garlic until soft.
- Mix shredded chicken, beans, corn, veggies, salsa, and spices in a large bowl.
- Layer tortillas, chicken mixture, and cheese in the casserole dish.
- Pour the sour cream and chicken broth mixture over the casserole.
- Bake for 30-35 minutes until bubbly.
- Garnish with cilantro and serve warm.
Common Mistakes to Avoid
- Using Too Much Liquid: If you add too much broth or salsa, your casserole might turn out soggy. Stick to the recipe measurements to avoid a watery dish.
- Skipping the Sauté: Don’t skip sautéing the onions, bell peppers, and garlic. This step adds depth of flavor that you won’t get if you toss everything in raw.
- Not Letting It Rest: Let the casserole rest for 5-10 minutes after removing it from the oven. This helps the layers set and makes serving much easier.
- Overcooking: Be careful not to overbake the casserole. Once the cheese is melted and bubbling, it’s ready to be pulled out.
Serving and Presentation Tips
To make your Mexican Chicken Casserole even more appealing, consider these serving and presentation ideas:
- Serve with Sides: Complement the casserole with a side of Mexican rice, refried beans, or a simple salad dressed with lime vinaigrette.
- Toppings: Offer toppings like avocado slices, extra sour cream, salsa verde, or jalapeños for guests to customize their plates.
- Presentation: For an eye-catching presentation, garnish with a sprinkle of freshly chopped cilantro and some lime wedges on the side.

- Sliced avocado: Fan out slices of ripe avocado on each plate for added creaminess.
- Crushed tortilla chips: Add a crunchy texture by sprinkling some crushed chips on top before serving.
Mexican Chicken Casserole Recipe Tips
- Use Rotisserie Chicken: Save time by using a store-bought rotisserie chicken. It’s already cooked and seasoned, making it a quick and easy addition to the dish.
- Make It Ahead: Assemble the casserole ahead of time and refrigerate it for up to 24 hours before baking. This makes it perfect for meal prepping or busy weeknights.
- Freeze for Later: Mexican Chicken Casserole freezes well. Simply bake, cool, and wrap tightly before freezing for up to 3 months. Reheat it in the oven for a quick and easy meal later on.
- Experiment with Cheeses: While a Mexican blend works well, feel free to mix and match cheeses. Pepper jack adds extra heat, while queso fresco brings a tangy note.
