  • Total Time: 30 minutes
  • Yield: 4 servings

Ingredients

Scale
  • 1 lb (450g) boneless, skinless chicken breasts or thighs, sliced into strips
  • 3 bell peppers (red, yellow, green), sliced
  • 1 large onion, sliced
  • 2 tablespoons olive oil
  • 2 teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and pepper to taste
  • Juice of 1 lime
  • Fresh cilantro for garnish (optional)
  • Tortillas for serving

Instructions

  1. Preheat your oven to 400°F (200°C). In a small bowl, mix chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper.
  2. Toss the sliced chicken and vegetables with olive oil and the spice mixture until evenly coated.
  3. Spread the seasoned chicken and vegetables evenly on a large sheet pan, avoiding overcrowding for proper roasting.
  4. Bake for 15-20 minutes until the chicken is cooked through and vegetables are tender, tossing halfway through for even browning.
  5. Remove from oven, squeeze fresh lime juice over the fajitas, and garnish with chopped cilantro if desired. Serve hot with warm tortillas.

Notes

  • Use uniformly sized vegetables for even cooking and better presentation.
  • Adjust spice levels by adding more chili powder for extra heat.
  • Slice chicken thinly to ensure quick cooking and tender bites.
  • If desired, add sliced jalapeños for an extra spicy kick.
