Introduction
Fajita Chicken Casserole Bake is a comforting, flavor-packed dish that brings all the bold elements of classic chicken fajitas into one easy, oven-baked meal. It is the kind of recipe I rely on when I want something hearty, colorful, and satisfying without juggling multiple pans on the stove. The combination of tender chicken, sautéed peppers and onions, warm spices, and melted cheese creates a dish that feels indulgent yet approachable. I first made this casserole on a busy weeknight, and it quickly became a repeat favorite because it reheats beautifully and works well for meal prep. I have even tried adding a spoonful of sour cream on top just before serving, which added a lovely creamy contrast. This casserole is ideal for feeding a family, hosting casually, or preparing ahead for stress-free dinners.

Onion

Olive oil

Cooked rice

Black beans

Corn

Cheddar cheese

Salt

Directions
Begin by preheating the oven to 375°F and lightly greasing a casserole dish. Cut the chicken into bite-sized pieces and place them in a large bowl. Add the sliced bell peppers, onion, olive oil, fajita seasoning, salt, and black pepper, then toss until everything is evenly coated.
Spread the seasoned chicken and vegetables evenly in the prepared baking dish. Bake uncovered for 25 minutes, stirring halfway through, until the chicken is mostly cooked and the vegetables are slightly tender.
Remove the dish from the oven and stir in the cooked rice, black beans, and corn until well combined. Sprinkle the cheddar and Monterey Jack cheese evenly over the top. Return the casserole to the oven and bake for an additional 15 to 20 minutes, or until the cheese is fully melted and bubbly and the chicken is cooked through. Let the casserole rest briefly before serving to allow the layers to set.
