A quick and easy sheet pan fajitas recipe featuring juicy chicken breasts and caramelized bell peppers, ready in just 20 minutes. Perfect for busy weeknights with minimal cleanup.

Ingredients

Scale
  • 1 pound boneless, skinless chicken breasts, sliced into thin strips
  • 3 medium bell peppers (mixed colors: red, yellow, green), sliced into strips
  • 1 large yellow onion, sliced into thin wedges
  • 2 tablespoons extra virgin olive oil
  • 2 tablespoons fajita seasoning (chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, black pepper)
  • Juice of 1 lime
  • Small handful fresh cilantro, chopped (optional)
  • 8 small flour or corn tortillas, warmed
  • Optional toppings: sour cream, shredded cheese, sliced avocado, salsa

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts into thin strips about ½ inch thick and place in a large bowl.
  3. Cut the bell peppers into thin strips about ½ inch wide and slice the onion into wedges of similar size. Add to the bowl with chicken.
  4. Drizzle 2 tablespoons of olive oil over the chicken and veggies. Sprinkle 2 tablespoons of fajita seasoning evenly. Toss everything well until all pieces are coated.
  5. Spread the mixture evenly on a rimmed sheet pan in a single layer, avoiding overcrowding.
  6. Roast in the oven for 15 minutes. After about 8 minutes, use tongs to flip or stir the chicken and vegetables for even cooking and color.
  7. Check doneness: chicken should be opaque with no pink inside, and peppers tender but not mushy. Roast an additional 2-3 minutes if needed.
  8. Remove from oven and squeeze fresh lime juice over everything. Toss gently to combine and garnish with chopped cilantro.
  9. Warm tortillas by wrapping them in foil and placing in the oven for the last 5 minutes, or warm individually in a dry skillet for 30 seconds per side.
  10. Serve immediately by piling chicken and peppers onto tortillas with your favorite toppings.

Notes

Slice chicken and vegetables evenly for uniform cooking. Avoid overcrowding the pan to ensure proper roasting and caramelization. Add lime juice after cooking to keep chicken juicy. For extra caramelization, broil for 1-2 minutes at the end but watch closely to avoid burning. Use corn tortillas for gluten-free option or serve as a bowl with rice or lettuce wraps. Chicken thighs can be used but may require longer cooking time.
