Prepare the Chicken
Heat the olive oil in a large skillet over medium heat. Add the chicken pieces and sprinkle with fajita seasoning. Cook for 6–8 minutes, stirring occasionally, until the chicken is cooked through and lightly browned. Remove the chicken from the skillet and set aside. -
Cook the Vegetables
In the same skillet, add the sliced red bell pepper, yellow bell pepper (if using), and onion. Sauté for 3–4 minutes, until the vegetables are tender but still vibrant. Season with a pinch of salt and pepper. -
Assemble the Casserole
Preheat your oven to 375°F (190°C). In a 9×13-inch baking dish, layer the cooked chicken, sautéed vegetables, and sour cream. Pour the chicken broth over the mixture and stir gently to combine. -
Top with Cheese
Sprinkle the shredded cheddar cheese and mozzarella cheese evenly over the casserole. -
Bake
Place the casserole in the preheated oven and bake for 15–20 minutes, or until the cheese is melted and bubbly. -
Garnish and Serve
Once baked, remove from the oven and garnish with fresh cilantro, if desired. Serve warm and enjoy!
