Ingredients

1 lb chopped chicken
1 onion, diced
1 green pepper, chopped
1 red pepper, chopped
1 (16 ounce) jar salsa (optional)
1 (14 1/2 ounce) can diced tomatoes, undrained
1 (14 ounce) can cream of mushroom soup
1 (10 ounce) package frozen corn, thawed
12 corn tortillas (6 inch)
1 lb shredded sharp cheddar cheese, divided
1 (4 ounce) can black olives

Equipment Needed

Large skillet
13×9 inch baking dish
Aluminum foil

Instructions

Preheat your oven to 375°F (190°C). This will ensure even cooking and perfectly melted cheese.
In a large skillet, brown the chopped chicken with the diced onion, chopped green pepper, and chopped red pepper. Stir frequently to prevent burning and ensure the chicken is cooked through. This step is crucial for building a flavorful base. Drain off any excess fat.
Stir in the salsa (if using), diced tomatoes (undrained), cream of mushroom soup, and thawed corn into the skillet with the chicken and vegetables. Bring the mixture to a boil, then reduce heat and simmer for a few minutes to allow the flavors to meld together.
Lightly grease your 13×9 inch baking dish to prevent sticking. Then, arrange 6 of the corn tortillas on the bottom of the dish, overlapping them as necessary to completely cover the surface. This forms the first layer of your casserole.
Spoon the chicken mixture evenly over the layer of tortillas. Then, sprinkle 1 cup of the shredded cheddar cheese over the chicken. This cheese layer will add a delicious, gooey element to the middle of the casserole.
Top with the remaining 6 corn tortillas, again overlapping as needed to cover the chicken and cheese layer.
Cover the baking dish tightly with aluminum foil. This helps to trap moisture and ensure the casserole heats through evenly without the top tortillas becoming too dry.
Bake in the preheated oven for 25 to 30 minutes, or until the casserole is heated through and bubbly around the edges.
Remove the baking dish from the oven and carefully remove the aluminum foil.
Sprinkle the remaining shredded cheddar cheese evenly over the top layer of tortillas.
Turn off the oven. Return the uncovered dish to the oven until the cheese is melted and bubbly, about 2-3 minutes. Keep a close eye on it to prevent burning.
Remove from the oven and let it sit for about 5 minutes before slicing and serving. This allows the casserole to set slightly, making it easier to serve neat portions.

Expert Tips & Tricks

For a richer flavor, try using bone-in, skin-on chicken thighs. Brown them in the skillet, then shred the meat after cooking. The rendered chicken fat will add depth to the dish.
If you want to add a smoky flavor, incorporate some chipotle peppers in adobo sauce into the chicken mixture. Start with one pepper and add more to taste.
Don’t be afraid to experiment with different types of cheese. Monterey Jack, pepper jack, or even a blend of Mexican cheeses would work well in this casserole.
If your casserole seems dry, add a splash of chicken broth or water to the chicken mixture before layering.
To prevent soggy tortillas, lightly toast them in a dry skillet before assembling the casserole. This will help them hold their shape and prevent them from absorbing too much moisture.
For a spicier kick, add a diced jalapeno pepper to the chicken and vegetable mixture. Be sure to remove the seeds and membranes for a milder heat.
If you’re short on time, use pre-cooked rotisserie chicken. Simply shred the chicken and add it to the skillet with the vegetables.
You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add a few extra minutes to the baking time to ensure it’s heated through.
To make individual servings, assemble the casserole in small ramekins or oven-safe dishes.

Serving & Storage Suggestions

Serve the Chicken Fiesta Casserole hot, straight from the oven. Garnish with a dollop of sour cream, a sprinkle of fresh cilantro, or a side of guacamole for extra flavor and visual appeal. A fresh green salad or a side of Mexican rice makes a perfect accompaniment. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) or in the microwave until heated through. For longer storage, freeze the casserole in individual portions for up to 2 months. Thaw overnight in the refrigerator before reheating.
