07 - Serve the chicken, pineapple, and vegetables in tortillas. Top with fresh cilantro and a squeeze of lime.

# Top Tips:

01 -
  • Everything cooks together on one pan, which means you can actually relax while dinner happens in the oven instead of standing over a stove.
  • The pineapple adds a natural sweetness and tanginess that makes these fajitas taste nothing like what you'd expect, in the best way possible.
  • It comes together in under 45 minutes total, making it perfect for those nights when you're hungry but not interested in complicated cooking.
02 -
  • Don't skip stirring halfway through—the bottom layer can stick or cook unevenly, and that one pause makes a huge difference in the final result.
  • The pineapple is delicate, so if you stir too aggressively it falls apart; just gently toss with tongs instead of a spoon.
03 -
  • Slice your chicken slightly thinner than you think you need to—it cooks faster and becomes more tender when it's not too thick.
  • Don't skip the parchment paper or foil because cleanup is genuinely the best part of a sheet pan dinner, and burned-on spiced oil is nobody's friend.
