Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts, sliced into thin strips
  • 3 bell peppers (red, yellow, green), sliced into strips
  • 1 medium yellow onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon cumin
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon crushed red pepper flakes (optional)
  • Salt and freshly ground black pepper, to taste
  • Juice of 1 lime
  • Chopped fresh cilantro (optional, for garnish)
  • Flour or corn tortillas, warmed (for serving)

Instructions

  1. Preheat the oven to 425°F (220°C) and allow it to reach temperature.
  2. Slice the chicken breasts into thin strips about 1/2 inch wide. Slice the bell peppers and onion into similar-sized strips.
  3. In a large bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, crushed red pepper flakes, salt, and pepper.
  4. Add olive oil to the bowl, then toss in the chicken strips, bell peppers, and onions. Mix well to coat evenly with seasoning and oil.
  5. Spread the chicken and vegetable mixture in a single layer on a large rimmed sheet pan, avoiding overcrowding.
  6. Roast in the oven for 20-25 minutes, stirring or shaking the pan halfway through, until chicken reaches 165°F (74°C) and veggies are tender with browned edges.
  7. Remove from oven, squeeze fresh lime juice over the top, and sprinkle with chopped cilantro if desired.
  8. Serve immediately by loading the chicken and veggies into warmed tortillas with your favorite toppings.

Notes

Do not overcrowd the pan to ensure proper roasting and caramelization. Use thin, even strips of chicken for quick and even cooking. Toss ingredients halfway through cooking to prevent sticking and promote even roasting. Fresh lime juice added after roasting brightens the flavors. For gluten-free, use corn tortillas. Chicken thighs can be used but may require longer cooking time.
