Ingredients
- 2 medium potatoes, peeled and thinly sliced
Potatoes provide the gratin's bulk, lending a creamy texture once baked. Their starchiness helps bind the layers, creating that signature indulgent mouthfeel. - 2 medium carrots, peeled and thinly sliced
Carrots add a natural sweetness that balances the dish, contrasting nicely with the earthiness of the potatoes. Their vibrant color also enhances the visual appeal of the gratin. - 2 medium parsnips, peeled and thinly sliced
Parsnips bring a sweet, nutty flavor that deepens the complexity of the dish. Their unique taste stands out against other root vegetables, giving the gratin a distinctive touch. - 1 small onion, finely chopped
Onions contribute a foundational layer of flavor, providing sweetness and depth. When sautéed, they release aromatic oils that enrich the overall taste. - 2 cups heavy cream
Heavy cream is essential for creating a rich and luscious sauce that envelops the vegetables. It provides the necessary fat content for a luxurious texture. - 1 ½ cups grated Gruyère cheese
Gruyère offers a nutty and slightly sweet flavor that melts beautifully, adding a creamy and gooey texture to the gratin. It also forms a golden, crispy topping that contrasts with the softness of the vegetables. - Salt and pepper to taste
Seasoning is crucial for bringing out the natural flavors of the vegetables and the richness of the cheese. Adjusting salt and pepper thoughtfully ensures a perfectly balanced dish. - 2 tablespoons fresh thyme leaves, chopped (optional)
Fresh thyme introduces an aromatic herbaceous note that brightens the overall flavor profile. It works wonderfully with root vegetables, enhancing their natural earthiness.
Directions & Preparation
Step 1: Preheat your oven to 375°F (190°C).
Preheating the oven ensures that your gratin will cook evenly and thoroughly from the start. This step is crucial as it prevents the dish from becoming soggy and allows for the cheese to brown nicely.
Step 2: In a large skillet, sauté the chopped onion over medium heat until translucent, about 5 minutes.
Sautéing the onions releases their sugars and enhances their sweetness, which forms a fundamental flavor base for the gratin. This step adds depth to the overall taste, making the dish more complex.
Step 3: Layer the sliced potatoes, carrots, and parsnips in a greased baking dish, alternating the vegetables for visual appeal.
Creating layers not only looks beautiful but allows each vegetable to integrate and absorb the cream and cheese evenly. This method helps ensure a well-balanced flavor in every bite.
Step 4: Sprinkle with salt, pepper, and thyme between the layers.
Seasoning at each layer ensures that every part of the gratin is flavorful. The thyme, if used, adds an aromatic lift that complements the vegetables and cheese, making every mouthful delightful.
Step 5: In a separate bowl, whisk together the heavy cream and half of the Gruyère cheese until well combined.
This mixture binds the vegetables while contributing a rich, creamy texture that envelops the gratin. The cheese will melt during baking, creating that signature gooeyness.
Step 6: Pour the cream mixture over the layered vegetables evenly, allowing it to seep between the layers.
This step is vital as it ensures that all the vegetables are coated with the creamy mixture, helping them cook uniformly. It also enhances the gratin's texture, ensuring each piece is deliciously creamy.
Step 7: Top the gratin with the remaining Gruyère cheese and some additional thyme if desired.
The final cheese layer will melt and form a golden crust as it bakes, creating a lovely contrast to the soft vegetables underneath. This step adds an enticing visual appeal, making the gratin irresistible.
Step 8: Cover with aluminum foil and bake for 30 minutes, then remove the foil and bake for an additional 20-30 minutes or until golden brown and bubbling.
Covering the gratin initially steams the vegetables, cooking them through. Removing the foil allows the top to crisp up, resulting in a delightful contrast between textures.
Step 9: Let it rest for 10-15 minutes before serving.
Resting allows the gratin to set, making it easier to slice and serving. This time also enhances the flavors, letting them meld beautifully for a more enjoyable dish.

The Heart of the Gratin: Choosing Your Vegetables
The beauty of a cheesy root vegetable gratin lies in its versatility. You can tailor it to your preferences by selecting different root vegetables. While potatoes, carrots, and parsnips are classic choices, feel free to incorporate sweet potatoes, turnips, or even beets for unique flavors and textures. Combining various kinds not only enhances the taste but also adds an array of colors that make the dish visually appealing.
Herbs That Elevate the Flavor
Herbs are a terrific way to boost the overall flavor of your gratin without adding excess calories. Fresh thyme is a classic choice, but other herbs like rosemary or sage can lend a delightful twist. Consider adding a bit of garlic for a savory note. Fresh herbs brighten the rich, creamy texture and provide a fragrant aroma that will have everyone eagerly anticipating this dish.
Perfect Pairings for Your Gratin
This dish pairs beautifully with a variety of mains, such as roasted meats or a hearty salad, making it a versatile side that can complement many meals. Serve it alongside grilled chicken, beef, or even a savory mushroom risotto. The richness of the gratin balances well with lighter dishes, helping to create a wonderfully harmonious dining experience that showcases your culinary prowess.
