Introduction
There's something magical about a cheesy root vegetable gratin that warms the heart and soul. This dish elevates humble root vegetables into a creamy, cheesy delight that’s perfect for sharing at family gatherings or a cozy dinner at home. With layers of flavor, melty cheese, and comforting creaminess, you’ll find it hard to resist going back for seconds.
Root vegetables like potatoes, carrots, and parsnips are not only nutritious but also add depth to the flavor of this gratin. Baking them until tender and golden brings out their natural sweetness, while the cheeses create a rich and crusty topping. This gratin is an opportunity to showcase the beautiful colors and textures of seasonal vegetables.
Ingredients
- 3 cups mixed root vegetables, sliced
Using a mix of root vegetables such as potatoes, carrots, and parsnips adds complexity to the dish. Each vegetable contributes its unique flavor and texture, resulting in a well-rounded gratin. - 2 cups heavy cream
Heavy cream provides a luscious creaminess that binds the dish together. It enhances the richness and helps create that desirable, velvety texture that coats the vegetables. - 1 cup shredded Gruyère cheese
Gruyère cheese melts beautifully, forming a gooey layer on top of the gratin. Its nutty flavor complements the sweetness of the root vegetables superbly. - 1/2 cup grated Parmesan cheese
Parmesan adds a salty kick and additional depth of flavor. Sprinkling it on top of the gratin creates a crisp, golden crust that contrasts nicely with the tender vegetables. - 2 tablespoons unsalted butter, for greasing
Butter not only prevents sticking but also adds a subtle richness to the bottom of the gratin dish, enhancing the overall flavor. - Salt and pepper to taste
Seasoning with salt and pepper is crucial to bring out the natural flavors of the root vegetables. This simple addition ensures the gratin isn't bland and has a balanced taste. - 1 teaspoon fresh thyme, chopped
Thyme adds a fragrant herbaceous note that elevates the dish. Its earthy flavor complements the root vegetables beautifully.
Directions & Preparation
Step 1: Preheat your oven to 375°F (190°C).
Preheating the oven is a vital first step as it ensures the gratin cooks evenly from the start. This temperature will allow the cheese to melt perfectly while allowing the root vegetables to soften without burning.
Step 2: Prepare the baking dish by greasing it with butter.
Greasing the baking dish is essential to prevent the gratin from sticking. The butter also adds an extra layer of flavor, helping to create a golden crust on the bottom.
Step 3: Layer the sliced root vegetables in the dish.
Arrange the root vegetables in overlapping layers. This technique not only looks appealing but ensures even cooking. Each layer should be seasoned with salt and pepper to enhance their natural flavors.
Step 4: Pour heavy cream over the layered vegetables.
The heavy cream is crucial as it infuses moisture into the root vegetables and helps create that rich, velvety texture. Pour it evenly to ensure every layer is well-coated, enhancing flavor and preventing dryness.
Step 5: Sprinkle the Gruyère and Parmesan cheeses on top.
Adding the cheeses creates a luscious melting layer that binds the gratin together while forming a deliciously golden crust. Feel free to be generous; the more cheese, the better the gratin!
Step 6: Sprinkle fresh thyme over the top.
Incorporating thyme at this stage not only adds flavor but also elevates the overall aroma of the gratin as it bakes. Its earthy notes complement the sweet root vegetables beautifully.
Step 7: Cover the baking dish with aluminum foil.
Covering the dish initially helps trap moisture and allows the vegetables to steam, ensuring they cook through without drying out. This step is key to achieving perfectly tender vegetables.
Step 8: Bake in the preheated oven for 40 minutes.
Baking the gratin for this amount of time allows the root vegetables to soften and absorb the cream. The foil cover prevents moisture loss, ultimately leading to a comforting, creamy consistency.
Step 9: Remove the foil and bake for an additional 15–20 minutes until golden brown.
Removing the foil at this stage allows the cheese on top to brown and become crispy, adding texture and flavor contrasts to the creamy depth below. Keep an eye on it to avoid burning.
Step 10: Let it cool for a few minutes before serving.
Allowing the gratin to rest helps the layers set, making it easier to serve. This cooling period also allows flavors to meld, enhancing the overall taste of the dish.

Choosing the Right Root Vegetables
When selecting root vegetables for your gratin, opt for a balance of flavors and colors. Potatoes provide a creamy base, while carrots and parsnips offer sweetness and brightness. Consider including turnips or sweet potatoes for added variety, each contributing unique textures and tastes. Seasonal vegetables not only enhance flavor but also create visual appeal.
Cheese Variations for More Flavor
While Gruyère and Parmesan are classic choices, feel free to experiment with other cheeses. Cheddar can lend a sharpness that contrasts beautifully with the cream, while a bit of feta or goat cheese can add an unexpected tang. Mixing cheeses not only enhances flavor but also creates a more complex profile, making each bite intriguing and delicious.
Serving Suggestions to Elevate Your Meal
This cheesy root vegetable gratin can be a centerpiece or a comforting side dish. Serve it alongside roasted meats, such as chicken or beef, to create a balanced meal. Or pair it with a light salad for a vegetarian-friendly option. The richness of the gratin plays well against tart dressings, so consider adding a simple vinaigrette to brighten your plate.
FAQs
What kind of cheese can I use for a sharper flavor?
Using aged cheddar or a mixture of sharp cheeses can provide a bolder flavor profile that complements the sweetness of the root vegetables.
What if my gratin is too thick after baking?
If the gratin seems too thick, adding a splash more cream or milk before baking can help achieve the desired consistency; be sure to mix in thoroughly.
Can I add more vegetables to this dish?
Absolutely! Vegetables like sweet potatoes, butternut squash, or even greens like kale can be added. Just ensure they're sliced thinly for even cooking.
What should I do if my vegetables are not cooking through?
If your vegetables are undercooked, cover the gratin with foil and return it to the oven for an additional 10–15 minutes, checking for tenderness.
Can this gratin be made in advance?
Yes, you can prepare the gratin a day ahead, cover it, and refrigerate it. Just allow it to come to room temperature before baking.
What herbs can enhance the flavor of the gratin?
Fresh herbs such as rosemary or sage can be added for extra flavor; add them along with the thyme for a delightful herbaceous note.
