A quick and easy weeknight dinner featuring crispy chicken and charred peppers roasted on a single sheet pan. This recipe uses a cornstarch hack for extra crunch without marinating.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts or thighs, cut into 1-inch strips
  • 2 tablespoons vegetable oil (avocado or light olive oil)
  • 3 large bell peppers (mixed colors), cut into 1-inch strips
  • 1 large yellow onion, cut into wedges
  • 1 teaspoon smoked paprika
  • 1 teaspoon ground cumin
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon chili powder
  • 1 tablespoon cornstarch
  • Salt and black pepper to taste
  • Fresh lime wedges for serving
  • Fresh chopped cilantro for serving
  • Warm flour or corn tortillas for serving

Instructions

  1. Preheat oven to 425°F (220°C).
  2. Pat chicken strips dry with paper towels to ensure crispiness.
  3. In a small bowl, mix smoked paprika, cumin, garlic powder, onion powder, chili powder, cornstarch, salt, and pepper.
  4. Place chicken in a large mixing bowl, add oil and spice rub, and toss until evenly coated with a light, dusty coating.
  5. Slice peppers into strips and cut onion into wedges.
  6. Line a large sheet pan with parchment paper or foil. Spread chicken in a single layer without overcrowding.
  7. Arrange peppers and onions around the chicken on the pan.
  8. Roast in the center rack for 15 minutes.
  9. Remove pan, flip chicken, and toss vegetables to ensure even browning.
  10. Return to oven and roast for another 15 minutes.
  11. Optional: Broil for the last 2-3 minutes for extra char, watching closely to prevent burning.
  12. Let rest for 2 minutes before serving with warm tortillas, lime wedges, and cilantro.

Notes

Do not overcrowd the pan as this will cause the chicken to steam instead of crisp. Ensure chicken is dry before seasoning. If using chicken breasts, check internal temperature reaches 165°F. For extra crispiness, use the broiler at the end but watch closely.
