  8. 8

Tips

Tip 1

Pat chicken dry before coating for better spice adhesion

Tip 2

Do not skip the 10-minute rest to allow juices to redistribute and keep meat moist

Good to Know

Storage

Refrigerate leftovers in an airtight container for up to 3 days. Reheat on a sheet pan at 350 degrees until warmed through.

Make Ahead

Prep vegetables and make spice marinade up to 8 hours ahead. Store covered separately. Assemble and bake when ready to serve.

Serve With

Warm tortillas and set out all toppings in separate bowls. Let diners assemble their own fajitas.

Common Mistakes

Watch

Do not overcrowd the sheet pan; give vegetables and chicken space or they will steam rather than roast

Watch

Do not skip the rest period; this allows the chicken to retain moisture
