Description
Cheesy Root Vegetable Gratin is the perfect balance of comfort, elegance, and seasonal flavor. This dish combines sweet potatoes, parsnips, and beets with a rich blend of cream, Parmesan, and Gruyère. Ideal for Thanksgiving, Christmas, or a cozy winter dinner, this gratin delivers warm, earthy notes and a luxurious texture. Why This Recipe Stands Out
- Beautiful layers of colorful root vegetables.
- Rich, creamy sauce infused with garlic and thyme.
- Perfect for holidays and special occasions.
- Easily customizable with different herbs, cheeses, or vegetables.
- Comforting yet sophisticated — a true crowd-pleaser.
Ingredients
- 2 medium sweet potatoes, thinly sliced
- 2 large parsnips, thinly sliced
- 2 medium beets, thinly sliced
- 2 cups heavy cream
- 1 cup grated Parmesan cheese
- 1 1/2 cups shredded Gruyère cheese
- 3 cloves garlic, minced
- 1 tablespoon fresh thyme leaves
- Salt and black pepper, to taste
- Butter, for greasing the dish
Instructions
- Preheat the oven to 400°F (200°C).
- Grease a 3-quart baking dish with butter.
- Using a mandoline, slice sweet potatoes, parsnips, and beets into uniform thin slices.
- In separate bowls, toss each vegetable with heavy cream, Parmesan, thyme, salt, and pepper.
- Add a thin layer of cream, Parmesan, and garlic to the bottom of the baking dish.
- Arrange vegetables in rows or layers — sweet potatoes, parsnips, and beets.
- Cover tightly with foil and bake for 40–45 minutes or until vegetables are tender.
- Remove foil, sprinkle Gruyère on top, and bake another 10–12 minutes until golden and bubbly.
- Garnish with fresh thyme before serving.
Notes
Wear gloves when handling beets to avoid staining. Coat beets lightly with cream to prevent color bleeding. For make-ahead: assemble up to one day in advance, refrigerate, and bake with an additional 5–7 minutes. Experiment with cheeses, herbs, or seasonal vegetables to customize your gratin.
