Ingredients
  

For the Gratin
  • 4 tablespoons Unsalted Butter Greasing the dish. Use olive oil for a dairy-free option.
  • 1-2 long Sweet Potatoes Peeled.
  • 3-4 large Parsnips Trimmed and peeled.
  • 3-5 small Beets Peeled (smaller beets will result in less bleeding).
  • 14 tablespoons Heavy Cream Divided; whole milk can be used for a lighter version.
  • 4 ounces Grated Parmesan Divided.
  • 1 tablespoon Minced Thyme Divided; use fresh for best flavor.
  • 1 clove Garlic Minced.
  • 1 ounce Shredded Gruyère For topping.
  • Salt and Pepper To taste.

Equipment

Method
 

Preparation
  1. Preheat your oven to 400°F (200°C). Grease your 3-quart baking dish with unsalted butter.
  2. Using a mandoline, slice sweet potatoes, parsnips, and beets into very thin rounds.
  3. Pour 4 tablespoons of heavy cream over sweet potatoes and parsnips, 2 tablespoons over beets. Top with ½ ounce of Parmesan and 1 teaspoon of thyme.
  4. Pour remaining ¼ cup cream into the greased dish, sprinkle with remaining Parmesan and minced garlic. Layer vegetables in alternating columns.
  5. Season the top layer with salt and pepper, cover with foil, and bake for 30 minutes.
  6. Remove the foil, sprinkle the shredded Gruyère on top, and bake uncovered for another 18-20 minutes.
  7. Garnish with fresh thyme before serving.
