  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

Scale
  • 1 lb boneless, skinless chicken breasts or thighs, sliced into strips
  • 3 bell peppers (red, yellow, green), sliced
  • 1 large onion, sliced
  • 3 tbsp olive oil
  • 2 tbsp fajita seasoning (or homemade blend)
  • 1 lime, juiced
  • Salt and pepper to taste
  • Tortillas for serving
  • Optional toppings: sour cream, shredded cheese, cilantro, salsa

Instructions

  1. Start by slicing the chicken, peppers, and onion into thin strips. Preheat your oven to 400°F (200°C).
  2. In a small bowl, whisk together 2 tablespoons of olive oil, fajita seasoning, lime juice, salt, and pepper. Toss the chicken strips in this mixture and let it marinate for at least 10 minutes.
  3. Spread the marinated chicken, sliced peppers, and onions evenly on a large baking sheet. Drizzle with remaining olive oil and toss gently to coat everything evenly.
  4. Place the sheet pan in the oven and bake for about 20-25 minutes, tossing halfway through, until the chicken is cooked through and vegetables are tender.
  5. Warm the tortillas. Fill them with the cooked chicken and vegetables, then top with your favorite toppings like sour cream, shredded cheese, cilantro, and salsa. Serve immediately.

Notes

  • Use chicken thighs for more flavor and moisture, adjusting cooking time slightly.
  • If you prefer a milder spice, reduce or omit chili powder or cayenne pepper.
  • For best results, marinate the chicken for at least 10 minutes before baking.
