A quick and easy sheet pan fajitas recipe featuring sliced chicken, colorful bell peppers, and onions roasted to tender perfection with bold fajita seasoning. Perfect for busy weeknights and minimal cleanup.

Ingredients

Scale
  • 1 pound boneless, skinless chicken breasts or thighs, sliced thinly
  • 1 red bell pepper, sliced into strips
  • 1 yellow bell pepper, sliced into strips
  • 1 green bell pepper, sliced into strips
  • 1 medium yellow or white onion, sliced into strips
  • 2 tablespoons olive oil
  • 2 tablespoons fajita seasoning (chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, pepper)
  • Juice of 1 lime
  • Fresh cilantro, chopped (optional, for garnish)
  • Tortillas, warmed (flour or corn)

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts or thighs into thin strips, about 1/2 inch wide.
  3. Slice bell peppers and onion into strips similar in size to the chicken.
  4. In a large mixing bowl, combine the chicken strips, sliced peppers, and onions.
  5. Drizzle with 2 tablespoons of olive oil and add the fajita seasoning. Toss everything together until well-coated.
  6. Spread the mixture out in a single layer on a rimmed sheet pan, giving each piece space to roast properly.
  7. Place the sheet pan in the oven and roast for 20-25 minutes, stirring halfway through, until chicken is cooked through and veggies are tender-crisp with caramelized edges.
  8. Remove from the oven and squeeze fresh lime juice over the top. Toss gently to combine.
  9. Serve immediately with warm tortillas and your favorite toppings such as sliced avocado, sour cream, or shredded cheese.

Notes

For best results, slice ingredients evenly to ensure even cooking. Toss halfway through roasting to encourage browning and prevent sticking. Use a high oven temperature (425°F) for caramelized edges. Rest chicken briefly after cooking to keep juices locked in. Avoid overcrowding the pan to prevent steaming. You can prep the chicken and veggies the night before to save time. Use parchment paper or foil on the pan for easier cleanup.
