# Directions:

01 - Preheat oven to 425°F. Line a large rimmed baking sheet with parchment paper or foil.

03 - In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, black pepper, and cayenne pepper.
04 - Sprinkle the spice blend over the chicken and vegetables, then toss well to ensure even coverage.
05 - Spread the mixture in a single layer on the prepared baking sheet.
06 - Roast in the oven for 20 to 25 minutes until chicken is cooked through and vegetables are tender with slight charring, stirring halfway through.
07 - Remove from oven and squeeze fresh lime juice over the cooked chicken and vegetables.
08 - Serve the chicken and vegetables in warmed tortillas, garnished with chopped cilantro and optional toppings.

# Expert Tips:

01 -
  • Everything roasts together on one sheet, so cleanup is as easy as crumpling parchment paper.
  • The spice blend creates a smoky, slightly spicy crust that clings to every bite of chicken and vegetable.
  • It feels like a restaurant fajita night but takes less than an hour from start to finish.
  • You can swap proteins or make it vegetarian without changing the core method.
02 -
  • Cutting the chicken into thin, even strips is crucial; thick pieces won't cook through in the same time as the vegetables and you'll end up with dry edges or raw centers.
  • Don't skip the halfway stir; it prevents the bottom layer from burning and ensures the peppers and onions caramelize evenly.
  • If your pan is too crowded, use two sheets; overcrowding traps steam and you lose that beautiful char.
03 -
  • Use parchment paper instead of foil if you want even easier cleanup; it never sticks and you can just throw it away.
  • Slice your vegetables and chicken as evenly as possible so everything finishes cooking at the same time.
  • Let the pan cool slightly before squeezing lime over it; adding citrus to a screaming-hot pan can make it splatter.
  • If you're doubling the recipe, use two pans and rotate them halfway through baking to ensure even heat distribution.
