Preheat your oven to 400°F (205°C). Lightly grease a baking dish or skillet large enough to hold the chicken in a single layer.
Step 2: Prepare the Chicken
Pat the chicken breasts dry with paper towels. This helps the seasoning stick and promotes better browning.
Step 3: Season Everything
In a large bowl, toss together:
-
Chicken breasts
-
Bell peppers
-
Onion slices
-
Olive oil
-
Fajita seasoning
Mix until everything is evenly coated.
Step 4: Assemble the Dish
Transfer the seasoned chicken and vegetables to the prepared baking dish. Spread everything out evenly so the chicken cooks properly.
Step 5: Bake (First Round)
Bake uncovered for 25–30 minutes, or until the chicken is nearly cooked through and the vegetables are tender.
Step 6: Add the Cheese
Remove the dish from the oven and sprinkle shredded cheese generously over each chicken breast.
Step 7: Final Bake
Return to the oven and bake for 8–10 more minutes, until the cheese is melted, bubbly, and lightly golden. The internal temperature of the chicken should reach 165°F (74°C).
Step 8: Rest & Garnish
Let the dish rest for 5 minutes, then garnish with fresh cilantro, lime juice, or sour cream if desired.
