Essential Ingredients for Cheesy Root Vegetable Gratin
Potatoes: Yukon Gold or russet potatoes form the starchy base that holds everything together in this Cheesy Root Vegetable Gratin. Their creamy texture when sliced thin absorbs the cheese sauce beautifully, creating that signature soft interior. I always choose firm ones to ensure they slice evenly without falling apart. In total, you’ll need about 2 pounds, peeled and ready to go.
Carrots and Parsnips: These add a subtle sweetness and earthiness that elevates the entire dish. Carrots bring a pop of color and beta-carotene, while parsnips offer a nutty depth that’s perfect for the Cheesy Root Vegetable Gratin. Slice them to about 1/8-inch thick for tenderness without mushiness—around 1 pound each works wonders in balancing flavors.
Cheddar Cheese and Cream: Sharp cheddar provides the melty, tangy core that defines Cheesy Root Vegetable Gratin, while heavy cream ensures a lush, velvety sauce. Grate 2 cups of cheese fresh for better melting, and use 2 cups of cream to coat the layers generously. This duo creates the indulgent topping that’s crispy on top and gooey below, making every forkful irresistible.
How to Make Cheesy Root Vegetable Gratin
Prep the Vegetables
Start by washing and peeling your root vegetables—potatoes, carrots, and parsnips—for this Cheesy Root Vegetable Gratin. Use a mandoline or sharp knife to slice them thinly, about 1/8-inch, which ensures they cook evenly and absorb the flavors. In my experience, uniformity is key; uneven slices can lead to some parts being underdone while others turn to mush. Toss the slices with a bit of salt as you go to draw out excess moisture, and preheat your oven to 375°F. This step sets the foundation for a perfectly layered dish that bakes up beautifully.
Assemble the Layers
Grease a 9×13-inch baking dish and begin layering your sliced vegetables, starting with potatoes as the base for stability. Alternate with carrots and parsnips, overlapping slightly to create a pretty pattern that will impress at the table. Pour half the cream mixture—warmed with garlic, thyme, and a pinch of nutmeg—over the first layer, then sprinkle with a generous handful of grated cheddar. Repeat for the second layer, pressing down gently to compact everything. The aroma at this point is already heavenly, hinting at the delicious Cheesy Root Vegetable Gratin to come—bake covered with foil for 45 minutes to let the veggies soften.
Bake to Golden Perfection
Remove the foil and top your assembling Cheesy Root Vegetable Gratin with the remaining cheese, breadcrumbs if desired, and a pat of butter for extra crispiness. Bake uncovered for another 20-25 minutes until the top is bubbly and golden brown, watching closely to avoid over-browning. The edges should be caramelized, and a knife should slide through the center effortlessly, indicating tender roots throughout. Let it rest for 10 minutes post-oven to set, making it easier to serve those gorgeous slices. This final step transforms the layers into a cohesive, comforting dish everyone’s sure to love.

- 03 3-4 large parsnips (ends trimmed and peeled)
- 04 3-5 small beets (peeled)

Instructions
Preheat oven to 400˚F. Grease a 3 quart baking dish with butter.

Pour 4 tablespoons cream over each sweet potatoes and parsnips, and 2 tablespoons cream over beets. Top each bowl of sliced vegetables with ½ ounce grated Parmesan and 1 teaspoon minced thyme. Season each bowl generously with salt and pepper and toss together until all vegetable slices are well coated.
Pour remaining 1/4 cup cream into the bottom of a 3 quart (oval) baking dish and sprinkle with ½ ounce of Parmesan and minced garlic.
Grab a stack of sweet potatoes and line them standing up on a bias, at the top of the baking dish. Follow the sweet potato with a row of parsnips, followed by a row of beets. Repeat with the remaining sweet potatoes, parsnips and beets, creating 6 rows of root vegetables.
Season top of gratin with salt, pepper and sprinkle of remaining Parmesan.
Cover with foil and bake for 30 minutes or until vegetables are soft.
Uncover gratin and top with shredded gruyere.
