# Preparation Steps:

01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or foil to facilitate cleanup.
02 - In a large bowl, combine olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne pepper if using, salt, black pepper, and lime juice.
03 - Add chicken strips, sliced bell peppers, and onion to the marinade. Toss thoroughly until all pieces are evenly coated.
04 - Spread the marinated chicken and vegetables in a single, even layer on the prepared baking sheet.
05 - Roast in the preheated oven for 22 to 25 minutes, stirring once halfway through, until chicken is fully cooked and vegetables are tender with slight charring.
06 - Remove from oven and serve immediately with warmed tortillas and optional toppings such as cilantro, sour cream, salsa, or guacamole.

# Expert Suggestions:

01 -
  • One pan means one cleanup, which honestly changes everything on a weeknight.
  • The chicken stays juicy because it roasts quickly at high heat, emerging tender and soaked in that smoky spice blend.
  • Those charred peppers and onions develop a natural sweetness that balances the heat perfectly.
02 -
  • Stirring halfway isn't optional—it's the difference between evenly roasted vegetables and some burnt, some pale bits.
  • Don't crowd the pan; if it looks packed, use two sheets and rotate them in the oven.
  • The chicken continues cooking slightly after removal, so pull it when it's just cooked through, not when it looks overdone.
03 -
  • If you're cooking for guests, prep and marinate everything an hour ahead; it gives the spices time to really meld with the chicken.
  • A instant-read thermometer takes the guesswork out of doneness—you're aiming for 165°F (74°C) in the thickest part of the chicken.
