A quick and easy sheet pan fajitas recipe featuring juicy chicken strips and colorful bell peppers, perfect for busy weeknights or last-minute dinners.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts or thighs, sliced into thin strips
  • 3 medium bell peppers (red, yellow, and green), sliced into thin strips
  • 1 large yellow or red onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon ground cumin
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon cayenne pepper (adjust to taste)
  • Salt and black pepper to taste
  • Juice of 1 lime
  • Optional garnishes: fresh cilantro, sliced avocado, sour cream, shredded cheese, warm tortillas

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts or thighs into thin strips about ½-inch wide. Slice the bell peppers and onion into similar-sized strips.
  3. In a small bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, cayenne pepper, salt, and black pepper.
  4. In a large mixing bowl, toss the chicken and sliced veggies with olive oil and the seasoning blend until evenly coated.
  5. Spread the chicken and vegetables evenly in a single layer on a rimmed baking sheet.
  6. Roast in the oven for 20-25 minutes, stirring and flipping halfway through (around 12 minutes) for even cooking. Chicken should reach an internal temperature of 165°F (74°C) and peppers should be slightly charred and softened.
  7. Remove from oven and squeeze fresh lime juice over the fajitas.
  8. Serve immediately with warm tortillas and optional garnishes like cilantro, avocado slices, or sour cream.

Notes

For best texture, use firm bell peppers without soft spots. Chicken thighs stay juicier than breasts. Flip and stir halfway through roasting to ensure even cooking and caramelization. Adjust cayenne pepper to control spice level. Let cooked ingredients rest a couple of minutes on the pan before serving to redistribute juices.
