Ingredients You’ll Need

Gathering the right ingredients is key to nailing this dish. Each component enhances the overall taste, texture, and vibrant color, making the casserole as appealing to the eyes as it is to the palate.

• Chicken breasts (1 ½ pounds, skinless and boneless): The star protein, cut into bite-size pieces for even cooking and easy serving.
• Fajita seasoning (2 tablespoons): A bold blend of spices that infuses the chicken with authentic Mexican flavor.
• Vegetable oil (1 tablespoon): Essential for sautéing the chicken to a perfect golden brown without sticking.
• Bell peppers (2 medium, sliced into strips): Adds vibrant color and a subtle sweetness that balances the spice.
• Yellow onion (1 medium, sliced): Brings a mellow sharpness and extra texture to the mix.
• Shredded cheese (1 ½ cups, your choice): The gooey melty magic that ties the whole casserole together perfectly.
• Fresh chopped cilantro (for garnish): Adds a bright, herbal note that lifts the dish beautifully.
• Salt (a pinch, optional): To enhance and fine-tune the seasoning exactly to your taste.

How to Make Cheesy Chicken Fajita Casserole Recipe

Step 1: Prepare and Season the Chicken

Start by cutting your chicken breasts into small, bite-sized pieces. This makes every forkful tender and easy to eat. Toss the chicken in a bowl and sprinkle the fajita seasoning evenly over it. Stir gently to coat each piece thoroughly, ensuring every bit of chicken is bursting with flavor.

Step 2: Cook the Chicken

Heat the vegetable oil in a skillet or oven-safe cooker over medium-high heat. Add the seasoned chicken and cook for about 5 to 6 minutes until it’s no longer pink inside and beautifully browned on the outside. This step locks in the juices and builds a savory base for the dish.

Step 3: Sauté the Vegetables

Next, add the sliced bell peppers and yellow onion to the skillet with the chicken. Cook together for 3 to 4 minutes until the veggies just begin to soften but still hold some crunch, providing a delightful contrast in texture.

Step 4: Assemble the Casserole

If you are using a skillet that isn’t oven-safe, transfer the chicken and vegetable mixture into a greased 9×13 inch baking dish. Spread everything out evenly to ensure consistent cooking and cheesy coverage.

Step 5: Add Cheese and Bake

Generously sprinkle the shredded cheese over the top of the mixture. Bake uncovered in a preheated oven at 350°F (175°C) for 15 to 20 minutes until the cheese is melted, bubbly, and slightly golden around the edges. This finishing touch adds irresistible creaminess to the dish.

Step 6: Garnish and Serve

Once baked, garnish the casserole with freshly chopped cilantro. This fresh herbal burst balances the richness beautifully and makes the dish feel extra special.
