Cheesy Root Vegetable Gratin Ingredients
For the Gratin
• Unsalted Butter – Greasing the baking dish; can be substituted with olive oil for a dairy-free option.
• Sweet Potatoes – Provides sweetness and structure; opt for long sweet potatoes, peeled and sliced thinly.
• Parsnips – Offers a slightly nutty flavor and texture; large parsnips, trimmed and peeled, are best.
• Beets – Adds color and earthiness; use small beets, peeled and cut into thin rounds.
• Heavy Cream – Ensures a rich, creamy texture; whole milk can be used for a lighter option, but it won’t be as creamy.

• Garlic Clove – Provides aromatic depth; adjust the amount to taste for preferred intensity.
• Shredded Gruyère – Melts beautifully, adding richness; similar melting cheeses like Comté or Fontina can be substituted.
• Salt and Pepper – Essential for seasoning; adjust to taste for the perfect balance.
For Serving
• Fresh Thyme Leaves – A touch for garnish; reinforces the beautiful herbal flavor of the gratin.
How to Make Cheesy Root Vegetable Gratin
-
Preheat the oven to 400°F (200°C) and grease a 3-quart baking dish with butter. This ensures your delicious gratin doesn’t stick during baking.
-
Slice sweet potatoes, parsnips, and beets into very thin rounds, aiming for even thickness. Use a mandoline if you have one—it’s a game-changer for uniform slices!
-
Drizzle 4 tablespoons of heavy cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Mix in parmesan and thyme, then season each bowl with salt and pepper for enhanced flavors.
-
Pour the remaining cream into the bottom of your greased baking dish, and layer it with additional Parmesan and minced garlic, creating a flavorful base for your vegetables.
-
Arrange the vegetables standing up in rows: sweet potatoes, parsnips, and beets. Repeat the layers until your dish is filled to the brim—this makes for a lovely visual presentation!
-
Season the top layer with a sprinkle of salt, pepper, and any remaining Parmesan before covering the dish tightly with foil.
-
Bake for 30 minutes until the vegetables are soft. This initial baking allows the flavors to meld beautifully!
-
Uncover, top with shredded Gruyère, and return to the oven for another 18-20 minutes until the cheese is melted, bubbly, and golden brown—the perfect finishing touch!

Expert Tips for Cheesy Root Vegetable Gratin
- Choose Fresh Vegetables: Always use fresh, seasonal root vegetables for the best flavor. Avoid old or soft veggies, as they can affect the gratin’s texture.

Cheesy Root Vegetable Gratin Recipe FAQs
What should I look for when choosing root vegetables?
Absolutely! For the best Cheesy Root Vegetable Gratin, select firm, fresh vegetables without dark spots or soft spots. Sweet potatoes should be smooth and even in color, and look for parsnips that are heavy for their size. When it comes to beets, smaller ones usually have a sweeter flavor and more delicate texture.
How should I store leftover gratin, and how long will it last?
After enjoying your delicious gratin, store leftovers in an airtight container in the refrigerator for up to 3 days. Make sure it’s completely cooled before sealing it to help maintain that luscious creamy texture!
Can I freeze Cheesy Root Vegetable Gratin?
Yes, you can! To freeze, wrap portions tightly in plastic wrap, then cover with aluminum foil. This method keeps your gratin fresh for up to 3 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and bake at 350°F (175°C) until heated through, which usually takes about 25-30 minutes.
What if my vegetables are not cooking evenly?
If you notice some vegetables are cooking faster than others, it might be due to uneven slicing. Using a mandoline can help achieve uniform thickness. In case you’re facing cooking issues, check for doneness with a fork; if some are still firm, you can cover the dish again and bake for an extra few minutes to ensure everything is tender.
Are there any dietary considerations I should be aware of?
Very! If you have specific dietary restrictions, make sure to substitute ingredients accordingly. For a dairy-free version, replace heavy cream with coconut cream or a non-dairy milk plus a little cornstarch for thickening. If you’re allergic to nuts, opt for cheese that doesn’t contain nuts or use a vegan cheese alternative for a similar effect.
