A quick and easy sheet pan chicken fajitas recipe that delivers big flavor with minimal fuss, perfect for busy weeknights or casual gatherings.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts, sliced into thin strips
  • 2 large bell peppers (red and yellow preferred), sliced into strips
  • 1 large onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon crushed red pepper flakes (optional)
  • Salt and black pepper to taste
  • Warm tortillas (corn or flour, your preference)
  • Fresh lime wedges
  • Chopped cilantro
  • Optional toppings: sour cream, shredded cheese, avocado slices, or salsa

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts into thin strips, about 1/2 inch wide. Toss the slices in a large mixing bowl.
  3. Core and seed the bell peppers, slice into strips roughly the same size as the chicken. Peel and slice the onion thinly. Add these to the bowl with the chicken.
  4. In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, crushed red pepper flakes, salt, and pepper. Sprinkle over the chicken and veggies.
  5. Add olive oil to the bowl and toss everything together until evenly coated.
  6. Spread the chicken and vegetable mixture out in a single layer on the sheet pan, giving everything some breathing room.
  7. Roast in the preheated oven for 20–25 minutes, stirring halfway through, until chicken is cooked through (internal temp 165°F / 74°C) and peppers are slightly charred but crisp-tender.
  8. Remove from oven and let rest for 5 minutes.
  9. Warm your tortillas by wrapping them in foil and placing them in the oven for a few minutes.
  10. Serve the chicken and veggies on warm tortillas with your favorite toppings and a squeeze of fresh lime.

Notes

Do not overcrowd the pan to avoid steaming; toss halfway through roasting for even cooking. Use ripe bell peppers for natural sweetness. For juicier chicken, consider using thighs. Spice mix can be prepared ahead and stored. Warm tortillas wrapped in foil keep soft and pliable.
