# Expert Tips:

01 -
  • Everything roasts together on one pan, leaving you with exactly zero pots and pans to scrub afterward
  • The high-heat roasting creates those gorgeous charred edges that make fajitas taste like they came from a restaurant kitchen
02 -
  • Slice your steak against the grain, which means cutting perpendicular to those long muscle fibers you can see running through the meat
  • Don't overcrowd the pan or you'll end up steaming everything instead of getting those gorgeous charred edges we're after
03 -
  • If you have time, let the meat marinate in the spices and oil for up to 2 hours before cooking
  • Prep all your ingredients before you start cooking, because this recipe moves fast once that oven is hot
