Instructions

  1. Step
    Preheat oven to 400˚F. Grease a cast iron skillet or baking dish with butter and set aside.
  2. Step
    Slice sweet potato, parsnips and beets into very thin rounds using a mandoline and transfer each vegetable to its own bowl.
  3. Step
    In a bowl, stir together the heavy cream, garlic, thyme, salt, and pepper. Pour ¼ cup of the cream mixture into the bottom of the prepared skillet or baking dish.
  4. Step
    Arrange the sliced vegetables in the skillet in curved rows or sections, grouping each vegetable together or alternating colours as desired. Pour the remaining cream mixture evenly over the vegetables.
  5. Step
    Cover with foil and bake for 35–40 minutes, or until the vegetables are beginning to soften.
  6. Step
    Remove the foil and sprinkle with aged cheddar and mozzarella. Bake uncovered for another 20–25 minutes, or until the vegetables are tender, the cream is bubbling, and the cheese is melted and golden.
  7. Step
    Let stand for 10 minutes before serving. Garnish with additional fresh thyme, if desired.
