# Expert Tips:

01 -
  • No hovering over a hot stove—everything cooks together while you prep the toppings.
  • The high oven heat gives you those charred edges without any smoky kitchen drama.
  • Minimal cleanup means you can enjoy dinner instead of scrubbing pans afterward.
02 -
  • Slice the steak against the grain or it turns tough—look for the direction of the muscle fibers and cut perpendicular.
  • Do not skip the halfway stir or the bottom layer will char too much while the top stays pale.
03 -
  • Use a cast iron sheet pan if you have one—it holds heat like a dream and gives you restaurant level sear marks.
  • Taste a piece of steak before serving and hit it with a pinch of flaky salt if it needs a final boost.
