Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin

Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C) while you prepare your baking dish. Generously grease a 3-quart baking dish with unsalted butter to ensure a beautiful release of your Cheesy Root Vegetable Gratin. The butter will create a delightful, slightly crisp texture on the bottom layer as it bakes.

Step 2: Slice the Vegetables
Using a sharp knife or mandoline, slice the sweet potatoes, parsnips, and beets into very thin rounds, about 1/8 inch thick. Keep each vegetable in separate bowls to maintain their distinct colors and flavors. This will not only help in layering but also ensure even cooking throughout the dish.

Step 3: Toss with Cream
Pour heavy cream over the sweet potatoes and parsnips, and do the same for the beets in their bowl. Sprinkle grated Parmesan and fresh thyme into each bowl, then season with salt and pepper. Gently toss each mixture until the vegetables are fully coated with the creamy, cheesy goodness.

Step 4: Create the Base Layer
Pour any remaining heavy cream into the bottom of the greased baking dish. Sprinkle the base with additional grated Parmesan and minced garlic, ensuring a rich flavor foundation for your Cheesy Root Vegetable Gratin. This step not only adds flavor but also helps prevent the vegetables from sticking to the dish.

Step 5: Layer the Vegetables
Begin arranging the prepared vegetables in stacked rows within the baking dish. Alternate layers of sweet potatoes, parsnips, and beets for visual appeal, allowing each vibrant color to shine through. This beautiful arrangement will not only be a feast for the eyes but will also create an even cook throughout.

Step 6: Season the Top
Once all the vegetables are layered neatly, season the top with additional salt, pepper, and sprinkle over any remaining grated Parmesan. This final layer will melt and create a deliciously cheesy crust, adding texture to your Cheesy Root Vegetable Gratin.

Step 7: Bake Covered
Cover the baking dish loosely with aluminum foil and bake in your preheated oven for 30 minutes. This step will allow the root vegetables to soften beautifully, absorbing all the flavors from the cream and seasonings.

Step 8: Add Gruyere and Finish Baking
After 30 minutes, carefully remove the foil and sprinkle the shredded Gruyere cheese across the top. Return the dish to the oven uncovered and bake for an additional 18-20 minutes. You’re looking for that perfect golden-brown topping and fork-tender vegetables, signifying the Cheesy Root Vegetable Gratin is ready to shine.

Step 9: Serve and Garnish
Once baked, remove the gratin from the oven and let it cool slightly before serving. Garnish with fresh thyme sprigs for a pop of color and extra herbal flavor. This Cheesy Root Vegetable Gratin is now ready to impress at your holiday gatherings or cozy family dinners!

Cheesy Root Vegetable Gratin Recipe FAQs

How do I choose ripe vegetables for the gratin?
Absolutely! When selecting sweet potatoes, look for ones that are firm and smooth without any dark spots or soft areas. Opt for beets that are vibrant in color and heavy for their size, signaling freshness. Parsnips should be firm and not have any blemishes. If you see any wrinkling or dark spots all over, it’s best to skip those!

How should I store leftover Cheesy Root Vegetable Gratin?
Very! Store any leftover gratin in an airtight container in the refrigerator for up to 3 days. It’s best to reheat in the oven covered with foil at 350°F (175°C) to maintain its creamy texture. This gentle reheating ensures it warms evenly without drying out.

Can I freeze this dish, and how?
Absolutely! To freeze your Cheesy Root Vegetable Gratin, first allow it to cool completely. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored for up to 2 months. When you’re ready to enjoy, thaw it in the fridge overnight and reheat in the oven at 350°F (175°C) for about 25-30 minutes, until thoroughly warmed.

What should I do if the gratin is too watery?
If you notice your gratin turned out a bit watery, don’t fret! It might be due to vegetables releasing too much moisture. In the future, consider using a slotted spoon to layer the vegetables to drain excess liquid before baking. Additionally, you can let the gratin bake uncovered for a few extra minutes to help evaporate any excess moisture.

Is this dish suitable for people with dairy allergies?
The more the merrier! For those with dairy allergies or preferences, you can easily swap out the heavy cream for full-fat coconut milk and use nutritional yeast instead of Parmesan for a delicious dairy-free alternative. Almond milk would also work, though the sauce will be a little thinner. Just make sure to check that all ingredients you use are allergy-friendly!
