Cheesy Root Vegetable Gratin

Cheesy Root Vegetable Gratin

A comforting and cheesy side dish made with layers of thinly sliced root vegetables baked in a rich, garlic-infused cream sauce and topped with melted Gruyère and white cheddar. Perfect for holiday dinners or cozy family meals.

Ingredients

  • 1 lb Yukon gold potatoes, peeled and thinly sliced
  • 2 large carrots, peeled and thinly sliced
  • 2 medium parsnips, peeled and thinly sliced
  • 2 cups heavy cream
  • 2 cloves garlic, minced
  • 1 tsp fresh thyme, chopped
  • 1 cup Gruyère cheese, shredded
  • 1 cup white cheddar cheese, shredded
  • 2 tbsp unsalted butter (for greasing the dish)
  • 1 tsp salt
  • 1/2 tsp black pepper

Instructions

  1. Preheat the oven to 375°F.
  2. Grease a 9×13-inch baking dish with butter.
  3. In a small saucepan, heat the heavy cream with minced garlic, thyme, salt, and pepper until just simmering. Do not boil.
  4. Arrange a layer of potatoes in the bottom of the dish, followed by a layer of carrots and then parsnips.
  5. Sprinkle a mix of Gruyère and white cheddar cheese over the vegetable layers.
  6. Repeat the layering process, finishing with a layer of cheese on top.
  7. Pour the warm cream mixture evenly over the entire dish.
  8. Cover with foil and bake for 30 minutes.
  9. Remove the foil and bake for an additional 25 minutes, or until the top is golden and bubbly.
  10. Let the gratin rest for 10 minutes before serving.

Notes

  • Use a mandoline slicer for even, thin vegetable slices.
  • Freshly grated cheese melts better than pre-shredded varieties.
  • You can substitute sweet potatoes, rutabaga, or turnips for other root vegetables.
  • Letting the gratin rest before serving helps the sauce thicken and settle.
