A hearty and comforting holiday side dish packed with the natural sweetness of root vegetables, creamy sauce, and a crispy cheesy topping.

Ingredients

Scale
  • 2 medium sweet potatoes, peeled and thinly sliced
  • 2 medium parsnips, peeled and thinly sliced
  • 2 medium turnips, peeled and thinly sliced
  • 1 cup heavy cream
  • 1/2 cup milk
  • 2 teaspoons minced garlic
  • 1 teaspoon dried or fresh thyme
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup shredded Gruyère cheese
  • 1/4 cup grated Parmesan cheese
  • Butter for greasing the baking dish

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
  2. Peel and thinly slice the sweet potatoes, parsnips, and turnips. Aim for slices about 1/8 inch thick for even cooking.
  3. In a large mixing bowl, whisk together heavy cream, milk, minced garlic, thyme, ground nutmeg, salt, and black pepper.
  4. Add the sliced vegetables to the bowl and gently toss to coat each piece in the creamy mixture.
  5. Begin layering the vegetables in your baking dish. Start with a layer of sweet potatoes, followed by parsnips, then turnips. Repeat until the dish is full, reserving any remaining cream mixture.
  6. Pour the remaining cream mixture evenly over the layered vegetables.
  7. Cover the baking dish tightly with aluminum foil and bake for 40 minutes.
  8. Remove the foil and sprinkle shredded Gruyère cheese and grated Parmesan cheese over the top.
  9. Return to the oven and bake uncovered for an additional 20–25 minutes, or until the top is golden and bubbling.
  10. Let the gratin rest for 10 minutes before serving to ensure the layers hold together.

Notes

[‘Slice vegetables evenly to ensure uniform cooking.’, ‘Make sure all vegetables are coated in the cream mixture before layering.’, ‘Alternate different vegetables for a beautiful presentation and balanced flavors.’, ‘Use a knife or skewer to check if the vegetables are tender before removing the foil.’, ‘Add cheese partway through baking to prevent burning and achieve a golden crust.’, ‘Pat vegetables dry before tossing them in the cream mixture to avoid a watery gratin.’]
