Step-by-Step Instructions for Cheesy Root Vegetable Gratin
  1. Preheat your oven to 400°F (200°C) and grease a 3-quart baking dish with softened unsalted butter.
  2. Slice the sweet potatoes, parsnips, and beets into thin rounds and place them in separate bowls.
  3. In a bowl, mix heavy cream, grated Parmesan, minced thyme, salt, and pepper. Coat sweet potatoes and parsnips in the cream mixture, while lightly coating the beets.
  4. Pour the remaining cream mixture into the greased baking dish and sprinkle extra Parmesan and minced garlic over it.
  5. Layer the vegetables starting with sweet potatoes, then alternating with parsnips and beets, creating six rows.
  6. Season the top layer with salt, pepper, and more Parmesan. Cover with foil and bake for 30 minutes.
  7. After 30 minutes, remove the foil and sprinkle shredded Gruyère on top. Bake uncovered for another 18-20 minutes until golden brown.
  8. Let it cool slightly, then garnish with fresh thyme leaves before serving.
