Cheesy Root Vegetable Gratin Ingredients

For the Gratin
• Unsalted Butter – Grease the baking dish for easy serving; olive oil works for a dairy-free substitute.
• Sweet Potatoes – Adds sweetness and structure; Yukon Gold potatoes can offer a milder flavor.
• Parsnips – Contributes a sweet, nutty flavor; regular potatoes can be substituted, but the taste will differ.
• Beets – Provide earthiness and vibrant color; consider using golden beets to prevent bleeding during cooking.
• Heavy Cream – Ensures a rich and creamy texture; whole milk is a lighter alternative but less creamy.
• Grated Parmesan – Offers umami and binding; Pecorino Romano is a great alternative.
• Fresh Thyme – Enhances the dish with herbal notes; dried thyme is usable but fresh yields the best flavor.
• Minced Garlic – Elevates overall flavor; jarred minced garlic can save you time.
• Shredded Gruyère – Melts beautifully to create a rich layer on top; Fontina is a good substitute for a similar meltiness.
• Salt and Pepper – Critical for seasoning; adjust these essentials to taste for the perfect balance.

Enjoy crafting this heartwarming Cheesy Root Vegetable Gratin as a perfect holiday side dish!

Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin

Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 400°F (200°C). While the oven heats up, grease a 3-quart baking dish generously with unsalted butter, ensuring it’s well-coated to prevent sticking. This will create a lovely golden crust for your Cheesy Root Vegetable Gratin.

Step 2: Slice the Vegetables
Using a sharp knife or a mandoline slicer, slice the sweet potatoes, parsnips, and beets into very thin rounds, about 1/8 inch thick. The thin slices will ensure even cooking and texture throughout the gratin. Arrange the sliced vegetables separately to prepare for the layering process.

Step 3: Mix the Cream and Seasoning
In a large bowl, combine the heavy cream, grated Parmesan, fresh thyme, minced garlic, salt, and pepper. Stir until well blended. This creamy mixture will be evenly distributed later, infusing the layers of your Cheesy Root Vegetable Gratin with rich flavor.

Step 4: Assemble the Dish
Pour a thin layer of the creamy mixture into the bottom of the greased baking dish. Then sprinkle a bit of Parmesan and minced garlic over this layer. This base will add flavorful depth and help keep the bottom layers moist while the dish bakes.

Step 5: Layer the Vegetables
Starting with the sweet potatoes, layer the sliced vegetables upright in the baking dish, stacking them in rows. Alternate between layers of sweet potatoes, parsnips, and beets to create a beautiful visual contrast. Press them tightly together for an appealing arrangement.

Step 6: Season and Bake
Once all the vegetables are layered, season the top with a sprinkle of salt, pepper, and the remaining Parmesan cheese. Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes, or until the vegetables are tender when pierced with a fork.

Step 7: Add Cheese Topping
After 30 minutes, carefully remove the foil to reveal the gratin. Sprinkle the shredded Gruyère cheese generously over the top. Return the dish to the oven uncovered and bake for an additional 18-20 minutes, or until the cheese is bubbling and golden brown.

Step 8: Garnish and Serve
Once the cheesy top is beautifully browned, remove the gratin from the oven and let it cool for a few minutes. Garnish with fresh thyme leaves for a pop of color and herbal aroma. Now your delightful Cheesy Root Vegetable Gratin is ready to bring warmth to your holiday table!

Expert Tips for Cheesy Root Vegetable Gratin

Avoid Beet Bleeding: Coating sliced beets lightly in cream before baking can prevent color bleeding, keeping your gratin visually appealing.
Prep Ahead: You can prepare the Cheesy Root Vegetable Gratin a day in advance. Just add 5-7 minutes to bake time when reheating for perfectly tender veggies.
Slice Evenly: Use a sharp knife or mandoline for uniform slicing of vegetables. This ensures even cooking and avoids any undercooked or overcooked pieces.
Customize Your Cheese: Feel free to experiment with different cheeses like cheddar or mozzarella for a unique twist on flavor and texture.
Seasoning Matters: Adjust salt and pepper to taste, but remember that stronger cheeses may reduce the need for additional salt. Always taste as you go!

Make Ahead Options

These Cheesy Root Vegetable Gratin layers are perfect for meal prep! You can slice the sweet potatoes, parsnips, and beets up to 24 hours in advance and store them in an airtight container in the refrigerator.
