Does no one else just dice them up and roast them (olive oil, salt, pepper, and sometimes herbs)? Crispy and delicious.
We also do this with beets, rainbow carrots, and brussels sprouts. It is always the first thing to go (and something we now make throughout the year).
We do this with butternut squash in place of sweet potatoes and have for years now. Same with the others, although beets and rainbow carrots aren't always in holiday rotation. Our family does a dish with parsnips, turnips, and leeks as well that's largely just a spin on roasting.
