Preparing Root Vegetable Gratin
Making a Root Vegetable Gratin is not only satisfying, but it also brings the comforting flavors of home-style cooking to your table. Follow these straightforward steps to create a rich and creamy dish that impresses everyone!
Preheat and Prepare the Baking Dish
Begin by preheating your oven to 400 degrees F. While it’s heating up, get your baking dish ready. Lightly grease a 13- x 9-inch baking dish with butter or cooking spray. This step ensures your gratin won’t stick and makes cleaning up a breeze afterward. Trust me, nobody wants a stuck-on cheesy mess!
Slice Your Root Vegetables
Next comes the fun part—slicing! Using a mandoline or a sharp knife, slice the following root vegetables into ⅛-inch-thick pieces:
- 2 large russet potatoes (about 1.5 pounds), peeled
- 1 large golden beet (about 1 pound), peeled
- 1 large fennel bulb (about 12 ounces), trimmed
- 2 large parsnips (about 10 ounces), peeled
The mandoline really helps achieve uniform thickness, which is key for even cooking. If you don’t have one, don’t fret; just try your best to make even slices for optimal results.
Combine Vegetables with Cream and Seasoning
In a large bowl, toss your sliced vegetables gently with 2 teaspoons of kosher salt and ¾ cup of heavy cream. This mix brings all the flavors together, ensuring every bite is creamy and delicious. If you want some added flavor, consider a sprinkle of freshly ground black pepper.
Layering the Gratin
Now it’s time to layer!
- Spread half of your vegetable and cream mixture evenly in the prepared baking dish.
- Sprinkle 1 cup of shredded Parmesan cheese on top.
- Add the remaining vegetable mixture on top, making sure it’s an even layer.
- Pour the remaining ¾ cup of cream over this layer, followed by another ½ cup of Parmesan for that glorious cheesy crust!
Finally, cover the dish loosely with aluminum foil to help it cook through without burning.
Baking the Gratin to Perfection
Pop the baking dish into your preheated oven and bake for 1 hour and 10 minutes. This allows the vegetables to soften beautifully. If you find that the top isn’t golden enough, uncover and bake for an additional 20 to 25 minutes until the cheese reaches that perfect golden brown color. Once baked, let it cool for about 15 minutes before serving. A sprinkle of freshly ground black pepper on top just adds that finishing touch!
Creating a delicious Root Vegetable Gratin is about embracing the beauty of simplicity. It’s easy enough for a weeknight dinner but looks fancy enough for entertaining. So why not gather your friends, share a few laughs, and enjoy a comforting meal together?

Variations on Root Vegetable Gratin
Gratin with Extra Veggies
Feeling adventurous? Elevate your Root Vegetable Gratin by incorporating additional veggies like sweet potatoes, carrots, or butternut squash. These colorful additions not only boost nutrition but can add delicious, sweet undertones to balance the savory cream and cheese. Imagine digging into a creamy dish that bursts with vibrant flavors! For a delightful twist, throw in some sautéed spinach or kale for that extra green goodness.
Gratin with Different Cheese Options
Switching up the cheese can make your Root Vegetable Gratin feel like a new dish every time. While Parmesan is a classic choice, consider mixing in Gruyère or aged cheddar for a richer flavor profile. If you're feeling a bit indulgent, a sprinkle of blue cheese can add a tempting tanginess.

Cooking Tips and Notes for Root Vegetable Gratin
Using a Mandoline for Perfect Slices
To achieve that delightful, even cook you desire in your Root Vegetable Gratin, using a mandoline is a game changer. This tool effortlessly produces uniform slices, ensuring each layer of potato, beet, fennel, and parsnip cooks at the same pace. If you don’t have a mandoline, a sharp knife can work in a pinch—just aim for ⅛-inch thickness. Remember, consistency is key to a well-cooked gratin!
How to Achieve a Golden Cheese Top
For that irresistible, golden cheese crust on your Root Vegetable Gratin, don’t shy away from generously sprinkling Parmesan cheese on top. During the last 20 to 25 minutes of baking, uncover the dish to let the cheese melt and brown beautifully. For an extra touch, you can also place it under the broiler for a minute or two—keep a close eye to prevent burning. Enjoy the crispy cheese as a flavorful contrast to the creamy vegetables!
