Ingredients
- 2 pounds boneless, skinless chicken breasts, cut into bite-sized pieces

- 1 packet fajita seasoning mix
Instructions
- Preheat the oven: Preheat your oven to 400°F (200°C).
- Prepare the chicken: Place the bite-sized chicken pieces in a large baking dish.
- Add the vegetables: Arrange the sliced bell pepper and onion over and around the chicken.
- Season: Sprinkle the fajita seasoning evenly over everything. Toss gently until the chicken and vegetables are well coated.
- Bake: Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and continue baking for another 10–15 minutes, or until the chicken reaches 165°F (74°C) internally and the vegetables are tender.

Description
This chicken fajita bake is juicy, savory, colorful, and packed with fajita flavor. The chicken absorbs the seasoning while the peppers and onions become tender and slightly caramelized. It’s naturally low in carbohydrates and makes a satisfying meal without tortillas, rice, or complicated ingredients.
Tips
- Cut the chicken into evenly sized pieces so everything cooks at the same rate.
- For extra flavor, let the seasoned chicken sit for 15–30 minutes before baking.
- Use a mix of red, green, and yellow bell peppers for a colorful dish.
- Always check the thickest chicken pieces with a meat thermometer before serving.
- If you like a little heat, add sliced jalapeños.
Variations
- Cheesy Fajita Bake: Sprinkle shredded cheddar or Monterey Jack over the top during the final 5 minutes.
- Creamy Version: Add a few spoonfuls of cream cheese before baking for a rich, creamy fajita casserole.
- Spicy Chicken: Use hot fajita seasoning and add fresh jalapeños.
- Extra Veggies: Add sliced mushrooms or zucchini while keeping the dish low carb.
- Avocado Finish: Top each serving with diced avocado and a squeeze of fresh lime.
