Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts
  • 3 medium bell peppers (red, yellow, green), sliced into strips
  • 1 large red onion, sliced into thin wedges
  • 3 tablespoons olive oil
  • 1 teaspoon garlic powder
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon paprika (smoked if possible)
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • 2 tablespoons fresh lime juice (from 1 lime)
  • A handful of fresh cilantro, chopped (optional)

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the bell peppers and onion into strips and wedges, keeping pieces roughly the same size.
  3. Cut the chicken breasts into 1-inch thick strips.
  4. In a large mixing bowl, combine olive oil, garlic powder, chili powder, cumin, paprika, salt, and black pepper to form a smooth seasoning oil.
  5. Add the chicken strips, bell peppers, and onion to the bowl and toss well to coat evenly.
  6. Line a rimmed 18×13-inch sheet pan with parchment paper or a silicone baking mat for easy cleanup.
  7. Spread the chicken and vegetables evenly in a single layer on the sheet pan, leaving space between pieces.
  8. Roast in the preheated oven for 20-25 minutes, flipping the chicken and stirring the veggies halfway through (around 12 minutes) for even browning.
  9. Check that the chicken reaches an internal temperature of 165°F (74°C) or cut into a piece to ensure no pink remains and juices run clear.
  10. Remove from oven and squeeze fresh lime juice over the chicken and veggies, tossing lightly to combine.
  11. Garnish with chopped cilantro if desired and serve immediately with warm tortillas, salsa, or guacamole.

Notes

Do not overcrowd the sheet pan to avoid steaming the ingredients. Flip the chicken and stir veggies halfway through roasting for even caramelization. Rest chicken a few minutes before serving to keep it juicy. Prep peppers and seasoning the night before to save time. Adjust cooking time if using chicken thighs instead of breasts.
