A quick and easy sheet pan fajita chicken with colorful bell peppers, seasoned with a flavorful fajita blend and roasted to perfection for a fuss-free, delicious dinner.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts
  • 3 medium bell peppers (red, yellow, and green), sliced into strips
  • 1 medium yellow onion, sliced into thin wedges
  • 3 tablespoons olive oil
  • 2 tablespoons fajita seasoning (chili powder, cumin, smoked paprika, garlic powder, onion powder, cayenne pepper)
  • Salt to taste
  • Black pepper to taste
  • Lime wedges (optional, for serving)
  • Fresh cilantro, chopped (optional, for garnish)

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts into 1/2 inch thick strips. Cut the bell peppers into similar-sized strips and slice the onion into wedges.
  3. In a large mixing bowl, combine the chicken, bell peppers, and onion. Drizzle with olive oil, sprinkle with fajita seasoning, salt, and black pepper. Toss well to coat evenly.
  4. Arrange the chicken and vegetables in a single layer on a large rimmed sheet pan. Avoid overcrowding.
  5. Roast in the oven for 20-25 minutes, flipping the chicken and stirring the veggies halfway through (around 12 minutes) for even cooking.
  6. Check that the chicken reaches an internal temperature of 165°F (74°C) or cut into the thickest piece to ensure no pink remains.
  7. Remove from oven, squeeze fresh lime juice over the top, and garnish with chopped cilantro if desired.
  8. Let rest a few minutes before serving.

Notes

Do not overcrowd the pan to avoid steaming. Use thin chicken strips for even cooking. Toss halfway through roasting for balanced browning. Use high heat (425°F) for caramelized peppers and juicy chicken. Squeeze lime juice before serving to brighten flavors. Leftovers keep well refrigerated for up to 3 days and reheat gently to avoid drying out.
