Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts
  • 3 medium bell peppers (red, yellow, green), sliced
  • 1 medium yellow onion, sliced
  • 3 tablespoons olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon chili powder
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon paprika
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon fresh lime juice
  • Fresh cilantro, chopped (optional)

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice the chicken breasts into thin strips about 1/2-inch thick.
  3. Core and thinly slice the bell peppers and peel and slice the onion into similar-sized strips.
  4. In a large mixing bowl, combine olive oil, garlic powder, chili powder, cumin, paprika, salt, and black pepper. Whisk to blend the spices evenly.
  5. Add the chicken strips, peppers, and onions to the bowl. Toss everything thoroughly until lightly coated with the spice oil mixture.
  6. Spread the mixture evenly in a single layer on a rimmed baking sheet, avoiding overcrowding.
  7. Place the sheet pan in the preheated oven and roast for 20-25 minutes, flipping the chicken and veggies halfway through cooking.
  8. Check for doneness: chicken should reach an internal temperature of 165°F (74°C), and peppers should be tender with slightly charred edges.
  9. Remove from oven and squeeze fresh lime juice over the top. Toss lightly to combine.
  10. Garnish with chopped cilantro if desired, and serve immediately with warm tortillas and your favorite toppings.

Notes

For extra crispiness, broil for the last 2-3 minutes but watch closely to avoid burning. Let the chicken rest for 5 minutes before serving to keep it juicy. Avoid overcrowding the pan to prevent soggy vegetables. Use parchment paper or foil on the baking sheet for easier cleanup. This recipe is naturally gluten-free and can be made dairy-free by skipping cheese toppings. For a low-carb option, serve with lettuce wraps instead of tortillas.
