Ingredients List for Mexican Chicken Casserole

Here’s what you’ll need to create this delicious casserole. Feel free to adjust the ingredients based on your preferences or what you have available in your pantry.

Main Ingredients:

• 3 cups cooked, shredded chicken (rotisserie chicken works great)
• 1 cup uncooked rice or 6-8 small flour tortillas (cut into strips)
• 1 can (10 oz) enchilada sauce (red or green, depending on preference)
• 1 can (14.5 oz) diced tomatoes (with green chilies for extra flavor)
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup corn kernels (frozen, canned, or fresh)
• 1 ½ cups shredded Mexican blend cheese (or cheddar)
• ½ cup sour cream (optional for extra creaminess)
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 teaspoon cumin
• 1 teaspoon chili powder
• 1 tablespoon olive oil (for sautéing)
• Salt and pepper, to taste

Optional Ingredients:

• ½ cup sliced black olives (for garnish)
• ¼ cup chopped cilantro (for garnish)
• 1 jalapeño, sliced (for some heat)
• ¼ teaspoon red pepper flakes (if you like extra spice)
• Sliced avocado or guacamole (for serving)

Substitutions and Variations

Protein Variations:

• Ground Beef or Turkey: Swap out the chicken for cooked ground beef or turkey for a different flavor profile.
• Vegetarian: Omit the chicken and add more beans or even crumbled tofu for a meatless version.
• Shrimp: For a seafood twist, add cooked shrimp instead of chicken, but stir it in toward the end to avoid overcooking.

Rice and Tortilla Variations:

• Brown Rice: Use brown rice instead of white rice for a healthier, fiber-packed option. Keep in mind that brown rice requires a longer cooking time.
• Quinoa: For a gluten-free and high-protein twist, use cooked quinoa in place of rice.
• Corn Tortillas: If you prefer a more authentic flavor, swap flour tortillas for corn tortillas.

Cheese Variations:

• Cheddar or Monterey Jack: If you don’t have Mexican blend cheese, use cheddar or Monterey Jack. Pepper Jack adds a spicy kick!
• Queso Fresco: Top the casserole with crumbled queso fresco or cotija cheese after baking for an authentic Mexican touch.

Sauce Variations:

• Salsa Verde: Replace red enchilada sauce with salsa verde for a tangy, green version of the casserole.
• Homemade Enchilada Sauce: If you have time, you can make your own enchilada sauce for a fresher taste.
• Tomato Sauce: If you’re out of enchilada sauce, substitute with tomato sauce, adding spices like cumin, garlic powder, and chili powder to enhance the flavor.

Step-by-Step Cooking Instructions

Follow these simple steps to prepare your Mexican Chicken Casserole. It’s a straightforward recipe that can be prepped in under 30 minutes and then baked to cheesy perfection!

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or a light coating of olive oil.

Step 2: Cook the Rice (If Using)

If you’re using rice as the base, cook it according to the package instructions. For extra flavor, cook the rice in chicken broth instead of water. Once done, set the rice aside to cool slightly.

Step 3: Sauté the Vegetables

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onion and sauté for about 3-4 minutes until softened. Add the garlic, cumin, and chili powder, and cook for another minute until fragrant.

Step 4: Mix the Filling

In a large mixing bowl, combine the shredded chicken, cooked rice (or tortilla strips if using tortillas), black beans, corn, diced tomatoes, sautéed onions and garlic, and enchilada sauce. Stir everything together until evenly combined. If you want a creamier texture, stir in ½ cup of sour cream at this stage.

Step 5: Assemble the Casserole

Pour half of the chicken mixture into your prepared baking dish, spreading it out evenly. Sprinkle ½ cup of shredded cheese over the layer. Add the remaining chicken mixture on top, and finish with the remaining shredded cheese, spreading it evenly over the casserole.

Step 6: Bake

Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted, bubbly, and slightly golden on top.

Step 7: Garnish and Serve

Once the casserole is baked, remove it from the oven and let it cool for about 5 minutes. Garnish with sliced black olives, chopped cilantro, jalapeño slices, or avocado slices if desired. Serve with sour cream, salsa, or guacamole on the side for extra flavor.

How to Cook Mexican Chicken Casserole: A Step-by-Step Guide

1. Preheat the Oven: Get the oven ready at 375°F and grease your baking dish.
2. Cook the Rice: If using rice, cook it per the instructions and set it aside.
3. Sauté the Veggies: Cook onions, garlic, and spices in a skillet until fragrant.
4. Combine Ingredients: Mix shredded chicken, rice or tortillas, veggies, beans, corn, and enchilada sauce in a large bowl.
5. Layer the Casserole: Spread half the mixture into a baking dish, add a layer of cheese, then repeat with the remaining mixture and cheese.
6. Bake: Bake covered for 20 minutes, then uncovered for 10-15 minutes until golden and bubbly.
7. Garnish and Serve: Let the casserole cool, garnish with your favorite toppings, and serve!

Common Mistakes to Avoid

• Overcooking the Chicken: Use pre-cooked chicken like rotisserie to avoid overcooking. If starting from raw chicken, cook it until just done to keep it tender.
• Too Much Liquid: If using canned ingredients, drain the black beans and tomatoes to avoid excess liquid that can make the casserole watery.
• Undercooked Rice: If using rice, make sure it’s fully cooked before assembling the casserole. The oven won't provide enough heat to cook raw rice completely.
• Burnt Cheese: Keep an eye on the casserole during the final bake. If the cheese is browning too fast, cover it with foil to prevent burning.
