Ingredients

Gather the following ingredients:

Main Ingredients

1 lb chicken breast, diced
2 bell peppers, sliced
1 onion, sliced
1 can black beans, drained
1 cup corn, frozen or canned
2 cups shredded cheese (cheddar or Mexican blend)
1 packet fajita seasoning
1 cup salsa
6 tortillas, cut into strips

Make sure to have all ingredients prepped and ready to go.

Instructions

Follow these steps to prepare your casserole:

Cook the Chicken

In a skillet over medium heat, add the diced chicken and sprinkle with fajita seasoning. Cook until the chicken is browned and cooked through, about 5-7 minutes.

Sauté the Vegetables

Add the sliced bell peppers and onion to the skillet and sauté until they are tender, around 5 minutes.

Mix Ingredients

In a large bowl, combine the chicken mixture, black beans, corn, and salsa. Stir until well mixed.

Assemble the Casserole

In a greased casserole dish, layer half of the tortilla strips, followed by the chicken mixture, and top with cheese. Repeat the layers, finishing with cheese on top.

Bake

Bake in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the cheese is bubbly and golden brown.

Let the casserole cool for a few minutes before serving.

Storage and Reheating Tips

Leftovers of the Hearty Chicken Fajita Casserole can be stored in an airtight container in the refrigerator for up to 3 days. When you're ready to enjoy again, simply reheat a portion in the microwave or pop it in the oven at a low temperature until warmed through. If you're planning to make it ahead of time, this casserole can also be frozen. Just ensure to let it cool completely before transferring it to a freezer-safe container. You can freeze it for up to 3 months, making it an excellent option for meal prep.

For best results when freezing, consider assembling the casserole without baking it first. This way, you can bake it fresh when you’re ready to eat. Just add an extra 10 minutes to the baking time if it’s been frozen. Enjoying this dish again will feel like a treat, and the comforting aroma will fill your home as it bakes!

Healthy Variations to Consider

For those looking to lighten up the dish, there are several healthy variations of the Hearty Chicken Fajita Casserole that still retain the bold flavors you love. You can use whole-wheat tortillas instead of regular ones to boost fiber content. Opting for low-fat cheese or even a dairy-free cheese alternative can cut calories while still providing that cheesy goodness. Adding more veggies like zucchini, spinach, or mushrooms not only increases the nutritional profile but also adds vibrant colors to your casserole.

If you're gluten-free, simply ensure your tortillas are certified gluten-free and you're good to go! This dish is inherently versatile, making it easy to cater to various dietary preferences without sacrificing taste. Experimenting with healthier ingredients means that you can enjoy your favorite comfort food while still making conscientious choices.
