How to Make and Beets
Step 1: Prep the Vegetables
Begin by peeling your beets and parsnips, then thinly slice all your root vegetables including the sweet potatoes. Consistent thickness helps them cook evenly, ensuring every layer of this gratin melds perfectly in texture and taste.
Step 2: Prepare Your Baking Dish
Butter a medium-sized baking dish to prevent sticking and to add a subtle richness to the finished dish. This small step guarantees your gratin will slide onto plates effortlessly after baking.
Step 3: Layer the Vegetables
Arrange the slices in alternating layers—sweet potatoes, parsnips, and beets—to create a beautiful mosaic of colors and flavors. This layering technique ensures the cream sauce reaches every bit of vegetable, infusing each slice with maximum deliciousness.
Step 4: Whisk and Pour the Cream Sauce
In a bowl, whisk together the heavy cream, minced garlic, salt, pepper, and your choice of thyme or rosemary until well combined. Pour this herbaceous cream sauce evenly over the layered vegetables, allowing it to seep down and envelop every layer.
Step 5: Add Cheese and Bake
Sprinkle the grated Gruyère or cheddar cheese followed by Parmesan evenly over the top. Cover the dish with foil and bake at 375°F (190°C) for 40 minutes. Then, remove the foil and continue baking for another 15 to 20 minutes until the top is golden brown and bubbly, and the vegetables are tender when pierced with a fork.
Step 6: Rest and Garnish
Let the gratin rest outside the oven for about 10 minutes. This resting time allows the cream to settle, making serving easier and presenting a perfectly cohesive dish. If desired, sprinkle fresh thyme leaves on top for a lovely herbal accent.
How to Serve and Beets

Garnishes
Fresh thyme leaves are the classic garnish here, adding an herbal brightness that cuts through the richness. You can also consider a light drizzle of good olive oil or a sprinkle of toasted nuts for an unexpected crunchy texture.
Side Dishes
This root vegetable gratin pairs wonderfully with simple protein like roasted chicken or grilled pork. A crisp green salad with a tangy vinaigrette also provides a refreshing counterpoint to the creamy and cheesy indulgence of the gratin.
Creative Ways to Present
For a stunning presentation that highlights and beets visually, serve the gratin in clear glass or white ceramic bakeware to show off the layering. Alternatively, cut it into individual portions shaped with a ring mold for a refined look perfect for dinner parties.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the gratin tightly with foil or plastic wrap and refrigerate. It will stay fresh for up to 3 days and can make a quick, comforting meal when reheated.
Freezing
This dish freezes well, perfect for meal prep. Wrap tightly in freezer-safe containers or heavy-duty foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating to preserve the texture of the root vegetables and cream sauce.
Reheating
Reheat leftovers in a preheated oven at 350°F (175°C) for about 20 minutes or until warmed through. Avoid microwaving if possible to maintain that delightful crispy cheese topping and creamy interior.
FAQs
Can I use other root vegetables instead of parsnips?
Absolutely! Carrots, rutabagas, or even turnips can substitute parsnips, bringing their own unique sweetness and texture while complementing the beets and sweet potatoes beautifully.
Is it necessary to peel the beets?
Peeling the beets results in a smoother texture and a cleaner flavor, but if you scrub them thoroughly and thinly slice, you can leave the skin on for extra nutrients and a bit more earthiness.
What cheese works best if I cannot find Gruyère?
Sharp cheddar is a fabulous alternative with its bold flavor, though styles like Emmental or Comté also melt well and add a lovely nuttiness to the gratin.
Can I make this dish vegan or dairy-free?
Yes! Substitute the cream with a rich coconut cream or cashew cream, and use vegan cheeses to keep that cheesy goodness while keeping it plant-based.
How do and beets affect the cooking time?
Because beets are denser than other root vegetables, slicing them thinly is key to ensuring they cook evenly and in sync with sweet potatoes and parsnips, avoiding overly long cooking times.
