HOW TO MAKE MEXICAN CHICKEN CASSEROLE:

STEP-BY-STEP INSTRUCTIONS:

Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with oil or nonstick spray.

Step 2: Mix the Filling
In a large bowl, combine the shredded chicken, cream of chicken soup, sour cream, diced tomatoes with green chilies, black beans, corn, chili powder, cumin, and garlic powder. Stir until everything is well blended.

Step 3: Layer the Casserole
In the bottom of your baking dish, layer half of the cut tortillas. Spread half of the chicken mixture over the tortillas. Sprinkle with half of the cheddar and Monterey Jack cheeses.

Repeat the layers: remaining tortillas, the rest of the chicken mixture, and top with the remaining cheese.

Step 4: Bake Until Bubbling
Cover the dish with foil and bake for 25 minutes. Then uncover and bake for another 10–15 minutes, or until the cheese is melted and bubbly with golden edges.

Step 5: Rest and Serve
Let the casserole sit for 10 minutes before serving to help it set. Garnish with fresh cilantro if desired, and serve with a side of avocado, lime wedges, or a simple salad.

HELPFUL TIPS:

• Use leftover rotisserie chicken to save time.
• Add chopped jalapeños or a few dashes of hot sauce for extra heat.
• Swap corn tortillas for flour if that’s what you have on hand.
• You can prep this the night before—just cover and refrigerate until ready to bake.
• Serve with a dollop of guacamole or a drizzle of salsa verde for even more flavor.
