Root Vegetable Gratin

Total Time
2 hrs

We love the earthy, sweet flavor of the root vegetable combination in this cheesy gratin, but you could also go with the classic all-potato version (use 5 large potatoes, about 3 1/2 lbs. total, in place of the celery root and parsnips).

Thomas J. Story

 2 cups heavy cream
