# How-To Steps:

01 - Set the oven to 425°F. Line a large sheet pan with parchment paper or aluminum foil.

# Expert Tips:

01 -
  • Dinner is ready in under 45 minutes with basically zero fuss or technique required.
  • One sheet pan means you can actually enjoy your meal instead of standing at the sink.
  • The flavor-to-effort ratio is honestly embarrassing—tastes like you know what you're doing in the kitchen.
02 -
  • Stirring halfway through is non-negotiable—the pieces closest to the edges will cook faster and you want everything even.
  • If your oven runs hot, start checking at 18 minutes; if it runs cold, give it the full 25—overcooked chicken is dry chicken and nobody wants that.
03 -
  • Cut your chicken slightly thinner than you think you need to—half-inch strips cook faster and more evenly than thicker pieces.
  • Don't skip the halfway stir; those caramelized edges are where the real flavor lives and you want them on every piece.
