- Parsnips – Adds a slightly sweet and nutty taste; carrots can be substituted if necessary.

Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven warms up, generously grease a 3-quart baking dish with unsalted butter to prevent the Cheesy Root Vegetable Gratin from sticking. A well-prepared dish ensures easy removal of the gratin after baking, so don’t skip this step!
Step 2: Slice Vegetables
Thinly slice the sweet potatoes, parsnips, and beets into uniform pieces, aiming for about 1/8-inch thickness. A mandoline slicer can help achieve consistent results, ensuring even cooking throughout. Take a moment to admire the beautiful array of colors and shapes as you prepare these root vegetables for layering in the gratin.
Step 3: Coat and Season
In separate mixing bowls, add the sliced sweet potatoes and parsnips. Toss them with 4 tablespoons of the heavy cream, ½ ounce of grated Parmesan, fresh minced thyme, salt, and pepper. Repeat this process with the beet slices, using 2 tablespoons of cream. This seasoning will infuse each layer of the Cheesy Root Vegetable Gratin with delicious flavor, enriching the overall dish.
Step 4: Layer Vegetables
Pour ¼ cup of cream evenly into the prepared baking dish, then sprinkle with the remaining ½ ounce of Parmesan and the minced garlic. Begin layering the coated vegetable slices upright in alternating rows, creating a visually stunning display of colors. Make sure to pack them tightly but don’t mash them down—this height adds appeal once baked!
Step 5: Bake Covered
Sprinkle the remaining seasonings and Parmesan over the top of the arranged vegetables. Now, cover the baking dish tightly with aluminum foil to retain moisture. Bake in the preheated oven for 30 minutes, until the root vegetables become tender and easily pierced with a fork, enhancing the flavors and aromas of the Cheesy Root Vegetable Gratin.
Step 6: Add Topping and Finish
Once the initial baking is complete, carefully uncover the dish. Generously sprinkle shredded Gruyère cheese over the top of the vegetables. Return the gratin to the oven and bake uncovered for an additional 18-20 minutes, or until the cheese is melted and bubbly with a beautiful golden brown color. This last step creates a savory, gooey finish that makes your gratin irresistible!
How to Store and Freeze Cheesy Root Vegetable Gratin
Fridge: Store leftover gratin in an airtight container for up to 3 days. Reheat gently in the oven at 350°F (175°C) to maintain its creamy texture.
Freezer: For longer storage, freeze the gratin before baking. Wrap it tightly in plastic wrap and foil. It can be frozen for up to 2 months. Thaw overnight in the fridge before baking.
Reheating: If reheating from the fridge, warm in the oven at 350°F (175°C) for about 20-25 minutes until heated through. Avoid microwaving for best results.
Baking from Frozen: To bake from frozen, add about 10-15 additional minutes to the baking time, ensuring the center is hot and bubbly.
Expert Tips for Cheesy Root Vegetable Gratin
• Choose Even Slices: Uniform thickness ensures all vegetables cook evenly; a mandoline helps achieve that perfect consistency.

Cheesy Root Vegetable Gratin Recipe FAQs
How do I choose the right root vegetables for this gratin?
Absolutely! Look for root vegetables that are firm and free from blemishes. Sweet potatoes should have smooth skins without dark spots, while beets should be vibrant and unblemished. Parsnips need to be firm and creamy white; avoid any that are soft or shriveled.
What is the best way to store leftover Cheesy Root Vegetable Gratin?
Very good question! After your gathering, cool the gratin to room temperature, then transfer it to an airtight container. It’ll keep well in the fridge for up to 3 days. Just reheat gently in the oven at 350°F (175°C) to restore the creamy texture.
Can I freeze Cheesy Root Vegetable Gratin?
Yes, you absolutely can! Freeze the gratin before baking. Make sure to wrap it tightly in plastic wrap and then cover it with foil. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge, and bake as directed, adding a bit of extra time if needed.
What should I do if my gratin doesn’t seem to set properly?
If you find your gratin is too soupy or doesn’t set, it likely needs a bit more baking time. Cover it with foil to avoid excessive browning and bake for 10-15 more minutes until the vegetables are tender, and the liquid has thickened. You can also try sprinkling a bit more cheese on top for a final melt.
Are there any allergies I should be aware of with this recipe?
Definitely! This recipe contains dairy, including heavy cream and cheese. If you or your guests have a dairy allergy, consider using plant-based cream and cheese alternatives. Additionally, always check labels for any other potential allergens, especially when substituting ingredients.
Can I prepare this dish ahead of time?
Yes, I often make this dish a day before serving! Simply assemble the gratin and store it wrapped in foil in the fridge. When you’re ready to serve, just pop it in the oven, keeping in mind that you might need to add 5-7 extra minutes to the baking time. This makes it incredibly easy to enjoy a stunning dish without the last-minute rush!
