Why Herb Roasted Vegetables Belong on the Thanksgiving Table

The combination of garlic, fresh herbs, and roasted root vegetables fills the house with cozy aromas that instantly feel like the holidays.

   This ensures everything cooks at the same rate.

2. Don’t Overcrowd the Pan
   Spread vegetables in a single layer so they roast instead of steam.

   For extra crispiness, broil the vegetables for 3–4 minutes at the end.
