Step-by-Step Instructions
- Preheat your oven to 400°F (200°C) and grease a 3-quart baking dish with softened unsalted butter.
- Slice sweet potatoes, parsnips, and beets into thin, even rounds using a mandoline slicer or sharp knife.
- Toss sliced sweet potatoes and parsnips with heavy cream, Parmesan cheese, fresh thyme, salt, and pepper until evenly coated.
- Pour a thin layer of heavy cream mixed with minced garlic and a sprinkle of Parmesan cheese into the greased baking dish.
- Layer sliced vegetables upright in the dish, starting with sweet potatoes, followed by parsnips, then beets, and repeat until all vegetables are used.
- Sprinkle the top layer with salt, pepper, and any remaining Parmesan cheese.
- Cover the baking dish with aluminum foil and bake for 30 minutes.
- Remove the foil, sprinkle shredded Gruyère cheese over the top, and bake uncovered for an additional 18 to 20 minutes until golden brown.
- Garnish with fresh thyme before serving and allow to cool slightly.

Notes
For an extra crunchy finish, consider adding breadcrumbs mixed with Parmesan on top before the final bake.
