Ingredients You’ll Need

These ingredients come together in a surprisingly simple way, but each one plays an essential role in building the gratin’s taste, texture, and gorgeous color palette. From the earthy beets to the nutty cheeses, every bite tells a delicious story.

• Sweet Potatoes: Their natural sweetness and soft texture balance the earthy flavors perfectly.
• Parsnips: Adding a subtle nutty flavor and firmness for contrast.
• Beets: For vibrant color and that tender, sweet earthiness.
• Olive Oil: Helps lightly coat the vegetables and bring out their natural flavors.
• Salt and Black Pepper: Basic seasoning that enhances every ingredient.
• Milk or Half-and-Half: Creates the creamy base that ties the gratin together.
• Butter: Adds richness and helps develop that beautiful sauce.
• Garlic: A punch of savory aroma for depth.
• Dried Thyme: Lends a delicate herbaceous note.
• Nutmeg: Adds warmth and subtle complexity to the cream.
• Gruyère or Mozzarella Cheese: Melts gorgeously, creating a gooey, golden topping.

• Fresh Thyme or Parsley: For a fresh, colorful garnish that brightens the dish.

How to Make and Beets

Step 1: Preheat and Prepare the Oven

Start by preheating your oven to 375°F (190°C). This temperature is perfect to slowly cook the vegetables until tender without drying them out. Lightly grease a medium baking dish to prevent sticking and help your gratin develop that beautiful golden crust later on.

Step 2: Slice the Vegetables

The key to a perfectly cooked gratin lies here. Peel your sweet potatoes, parsnips, and beets, then slice them thinly and evenly. Thin slices ensure even cooking and the delicate layering that makes this dish so visually stunning. Toss the slices in olive oil, salt, and pepper to lightly season them and bring out their natural sweetness and earthiness.

Step 3: Create the Creamy Sauce

In a small saucepan over medium heat, melt the butter gently. Add minced garlic and let it cook for about a minute until fragrant but not browned. Stir in the milk or half-and-half along with dried thyme, nutmeg, salt, and pepper. Warm the sauce gently, making sure it doesn’t come to a boil – you want it silky smooth and flavorful to soak the vegetables.

Step 4: Assemble the Layers

Arrange the vegetables in alternating layers inside your greased baking dish. This layering showcases the beautiful colors and ensures every bite includes a mix of sweet potatoes, parsnips, and beets. Pour the creamy sauce evenly over the top to help everything meld together as it bakes.

Step 5: Bake Covered

Cover the dish with foil to trap steam and moisture. Bake for about 40 minutes so the vegetables soften up nicely without browning too soon. This step lets all those flavors begin to mingle while preserving the moisture of the beets and parsnips specifically.

Step 6: Add Cheese and Finish Baking

Remove the foil, then sprinkle the shredded Gruyère or mozzarella along with grated Parmesan cheese evenly on top. Return the dish to the oven uncovered for another 20 to 25 minutes. The cheese will melt into a bubbly, golden crust while the vegetables become tender and perfectly cooked.

Step 7: Rest and Garnish

Once out of the oven, let your gratin rest for about 5 minutes to set. This step makes serving easier and allows the creamy sauce to thicken slightly. Garnish with fresh thyme or parsley for an inviting finish that adds both color and a fresh herbal note.

How to Serve and Beets

Garnishes

Fresh herbs are the easiest way to brighten and freshen the dish visually and flavor-wise. Parsley adds a clean, peppery note while thyme brings earthy complexity that complements the root vegetables perfectly. You can also add a sprinkle of crispy breadcrumbs or a drizzle of high-quality olive oil to elevate the presentation further.

Side Dishes

This gratin and beets dish pairs wonderfully with roasted meats, such as a juicy roast chicken or tender pork loin. It also stands up beautifully next to a crisp green salad or steamed green beans for a lighter contrast. The richness of the gratin balances well with fresh, crisp vegetables or even a tangy vinaigrette on the side.

Creative Ways to Present

For a more elegant touch, consider serving the gratin in individual ramekins or small ovenproof dishes. It makes for a charming presentation at dinner parties. Alternatively, layer the vegetables in a clear glass dish to showcase the vibrant colors and layers, turning your gratin and beets into a visual feast almost too beautiful to eat—almost!

Make Ahead and Storage

Storing Leftovers

After cooling the gratin to room temperature, cover and store leftovers in the refrigerator for up to 3 days. The flavors actually deepen as they rest, making leftovers a delicious treat. Just keep the dish tightly wrapped to prevent the cream sauce from drying out.

Freezing

This dish freezes well for longer storage. To freeze, transfer cooled portions into airtight containers or freezer-safe bags. Keep frozen for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating to preserve texture and flavor.

Reheating

To reheat, place the gratin in a preheated oven at 350°F (175°C) covered with foil to retain moisture. Heat for 20 to 30 minutes until warmed through. For a quicker option, you can microwave individual portions but be aware the texture might be less crisp on top.

FAQs

Can I use other root vegetables in this gratin and beets recipe?

Absolutely! Carrots, turnips, or even rutabagas can add interesting flavors and textures. Just be sure to slice them thinly for even cooking alongside the sweet potatoes, parsnips, and beets.

Is it necessary to peel the beets?

Peeling beets is recommended because their skins can be tough and may affect the dish’s texture. However, if the beets are young and tender, you might get away with scrubbing them well instead.

Can I make this dish dairy-free?

Yes! You can substitute plant-based milk and vegan butter or margarine to make it dairy-free. Use a dairy-free cheese alternative for the topping to keep the gratin creamy and delicious.

How do I prevent the beets from bleeding their color too much?

Layering the beets between the other vegetables helps contain their color. Also, tossing them lightly with olive oil and promptly layering keeps the colors vibrant without excessive bleeding into the sauce.

Can I prepare parts of the gratin ahead of time?

You can slice the vegetables and prepare the cream sauce a day in advance, then assemble and bake when ready. This makes it convenient to save time on busy days while still enjoying a homemade meal.
