While the turkey roasts, combine the vegetables and rosemary on a rimmed baking sheet. Drizzle with oil and season with salt and pepper; toss to combine. Cover with foil.
After the turkey has roasted an hour, place the vegetables on the second rack in the oven. Roast 1 1/2 hours, uncover, and roast 30 minutes longer, tossing occasionally until vegetables are tender and golden brown.
I make this side dish for guests all fall long! It is so easy and healthy. I have also added turnips, yellow onion, sweet potato, and red skin potato to the mix for greater variety (and knowing that potato is in the pile made my husband give it a try - and he loved it).
Sans turkey, I roasted at 450 F for 30-45 minutes, then reduced heat to around 350-400 F for another half hour. Uncovered, and roasted 10-15 minutes more while I prepared quinoa as a side. Delicious. Beautiful presentation and aroma.
Perfect for holidays in autumn and winter.
Slice veggies smaller for shorter roasting time.
