# Expert Tips:

01 -
  • Everything roasts together, making cleanup so quick you actually have time to relax before eating.
  • The flavor-packed marinade turns ordinary chicken and veggies into something truly memorable.
02 -
  • Piling veggies too high keeps them from browning; spread them out for better results.
  • Marinating chicken for a couple hours really amps up the flavor—don’t rush if you have time.
03 -
  • Leave space between pieces so they roast instead of steam—crowding is a common pitfall.
  • Add fresh herbs at the end to preserve their color and aroma.
