# How to make it:

01 - Set oven to 425°F. Line a large baking sheet with parchment paper or foil for easier cleanup.
02 - Mix olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne pepper (if using), salt, black pepper, and lime juice in a large bowl.
03 - Add chicken strips, sliced bell peppers, and onion to the marinade. Toss thoroughly to ensure even coating.
04 - Spread the chicken and vegetables in a single layer on the prepared baking sheet.
05 - Cook in the preheated oven for 22 to 25 minutes, stirring once halfway through, until chicken is fully cooked and vegetables are tender with slight char.
06 - Remove from oven and serve promptly with warmed tortillas and desired toppings.

# Expert Suggestions:

01 -
  • One baking sheet means you're done cleaning before dessert even exists.
  • The chicken stays juicy while the peppers char just enough to turn sweet and smoky.
  • This is the rare weeknight meal that actually looks impressive without pretending it took longer than it did.
02 -
  • Don't skip the stirring halfway through—the bottom pieces cook faster and the top ones will dry out if you leave them still.
  • The chicken is done when it's white all the way through and doesn't bend when you press it with a spatula; a meat thermometer reads 165°F (74°C) if you want to be certain.
03 -
  • Pat the chicken dry with paper towels before marinating; it helps the spices stick instead of sliding around on moisture.
  • If your peppers aren't browning as much as you'd like, increase the oven temperature to 230°C (450°F), but watch carefully so nothing burns.
