Mashed Celeriac & Potato Casserole
Celeriac adds a bright celery-like flavor and lightens the texture in this healthy mashed potato casserole. The fried shallots are reminiscent of the crispy onions that top a green bean casserole.
To make ahead: Refrigerate unbaked casserole (Steps 1 & 3) for up to 2 days; let stand at room temperature for 1 hour before baking.
