  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

Scale
  • 2 lbs boneless, skinless chicken breasts or thighs, sliced into strips
  • 3 bell peppers (assorted colors), sliced
  • 1 large onion, sliced
  • 3 tablespoons olive oil
  • 2 teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Lime wedges and fresh cilantro for garnish
  • Tortillas for serving

Instructions

  1. Start by slicing the chicken, bell peppers, and onions into even strips to ensure uniform cooking and flavor absorption.
  2. In a small bowl, combine chili powder, cumin, paprika, garlic powder, onion powder, salt, and black pepper. Toss the chicken strips with 2 tablespoons of olive oil and the spice mixture until evenly coated. Let marinate while preparing vegetables.
  3. Preheat the oven to 400°F (200°C). Spread marinated chicken, peppers, and onions evenly on a large sheet pan. Drizzle with remaining 1 tablespoon of olive oil.
  4. Roast for 20-25 minutes until the chicken is cooked through and vegetables are tender.
  5. Remove from oven, squeeze lime juice over the fajitas, and garnish with chopped cilantro. Serve hot with warm tortillas for an authentic flavor experience.

Notes

  • You can prepare the chicken and vegetable marinade in advance and store it in the refrigerator for up to 24 hours.
  • For extra flavor, add sliced jalapeños or your favorite spice blends.
  • Storing leftovers separately helps maintain freshness—reheat in the microwave or skillet.
