# Expert Advice:

01 -
  • Roasting vegetables this way unlocks flavors you never taste when they’re simply sautéed—I almost wanted to keep it my own little secret.
  • This dish is wonderfully forgiving: swap veggies as you like or whatever’s looking best at the market, and it’s still a knockout.
02 -
  • Crowding the pan will make your veggies steam and turn mushy—use two trays if needed.
  • Once I tried skipping the halfway stir, and the bottom veggies nearly scorched—always give them a quick flip for even caramelization.
03 -
  • Always line your pan with parchment—clean up is a breeze and nothing sticks.
  • A quick finish under the broiler will give an extra bit of golden caramelization if you love crispy edges.
