Ingredients
- 2 cups potatoes, thinly sliced
Potatoes are the base of the gratin, providing a creamy, starch-heavy texture that absorbs flavors and contributes to the overall heartiness of the dish. - 1 cup carrots, thinly sliced
Carrots add a slight sweetness and vibrant color, complementing the earthy notes of the potatoes while enhancing the gratin's visual appeal. - 1 cup parsnips, thinly sliced
Parsnips offer a unique sweet and nutty flavor that deepens the dish's complexity, making it more than just another potato bake. - 2 cups heavy cream
Heavy cream binds the ingredients together and contributes to the rich, velvety texture of the gratin as it bakes. - 1 cup grated cheese (e.g., Gruyère or cheddar)
Cheese provides a flavorful kick and a golden, bubbling crust that contrasts beautifully with the tender vegetables. - 1 teaspoon garlic, minced
Garlic adds aromatic depth, infusing the dish with its unmistakable savory aroma that enhances all the flavors. - 1 tablespoon fresh thyme, chopped
Thyme brings an earthy freshness, complementing the root vegetables and balancing the creaminess of the gratin. - Salt and pepper to taste
Essential for enhancing flavors, seasoned salt and black pepper will ensure that every layer of the gratin is flavorful. - 2 tablespoons butter, for greasing
Butter prevents sticking and adds a rich flavor to the crispy edges of the baked gratin, helping achieve that desirable golden-brown crust.
Directions & Preparation
Step 1: Preheat the oven to 375°F (190°C).
Preheating the oven is essential to ensure even cooking right from the start. It guarantees that the gratin will bake uniformly, resulting in perfectly tender vegetables and a bubbling cheese crust.
Step 2: Prepare the baking dish by greasing it with butter.
Greasing the dish with butter helps prevent the gratin from sticking, allowing for easy serving. It also enhances the flavor and encourages a beautifully crisp crust.
Step 3: Layer the sliced potatoes, carrots, and parsnips in the dish.
Layering the vegetables allows for even cooking and ensures that each bite contains a balance of flavors. Arrange them attractively for a beautiful presentation once baked.
Step 4: In a bowl, combine heavy cream, garlic, thyme, salt, and pepper.
Mixing these ingredients together creates a creamy sauce that infuses the vegetables with flavor. This mixture acts as the magic glue, uniting all the layers into a harmonious dish.
Step 5: Pour the cream mixture evenly over the vegetables.
Pouring the sauce over the layered vegetables ensures that each piece is coated, allowing the flavors to penetrate. It also encourages the gratin to bake evenly.
Step 6: Sprinkle grated cheese on top of the layered vegetables and cream.
The cheese forms the coveted crust that adds texture and flavor to the gratin. Choosing a cheese with good melting properties ensures a bubbly, golden topping.
Step 7: Cover the dish with foil and bake for 45 minutes.
Covering the dish with foil helps steam the vegetables, ensuring they cook through without burning. This step is crucial for achieving tenderness before browning the cheese.
Step 8: Remove the foil and bake for an additional 15-20 minutes until golden brown.
This step allows the cheese to caramelize, creating a crispy, irresistible crust. Watch closely to prevent burning; a golden hue indicates perfection!

Choosing the Right Cheese for Flavor
The type of cheese can greatly impact the flavor profile of your gratin. Gruyère is a classic choice due to its nutty, slightly sweet flavor and excellent melting properties. Cheddar can offer a sharper taste, adding complexity. Mixing cheeses, like a bit of mozzarella for stretch and a stronger cheese for flavor, can create a balanced and delicious topping.
Variety of Vegetables to Experiment With
While this recipe focuses on potatoes, carrots, and parsnips, feel free to experiment with other root vegetables. Sweet potatoes, rutabagas, or even turnips can add unique flavors and textures. Aim for a mix that balances sweetness and earthiness; this creates more depth in your gratin while taking advantage of seasonal produce.
Perfecting the Creaminess of Your Gratin
Achieving the perfect creamy texture is key to a delicious gratin. The heavy cream in this recipe is essential, but you can also add a splash of milk or broth for fluidity without sacrificing richness. Adjust the seasoning carefully, as cream will mellow flavors, ensuring every layer shines through in the final dish.
FAQs
What if my gratin seems too thick after baking?
If the gratin is too thick, it might need more cream added to the mixture next time or bake it covered for a bit longer to ensure the vegetables soften properly.
Can I use frozen root vegetables for this dish?
While fresh vegetables yield the best texture, frozen root vegetables can be used. Just ensure they are thawed and drained to avoid excess moisture.
What should I do if my cheese isn't browning?
If the cheese isn't browning, you may need to increase the oven temperature for the final 15 minutes. You can also use the broiler for a short time, but watch closely to avoid burning.
How can I adjust the seasoning for more flavor?
Taste the cream mixture before pouring it over the vegetables. You can add more salt, pepper, or herbs based on your preference to enhance overall flavor.
Can I double this recipe for a larger crowd?
Yes, you can easily double this recipe. Just ensure your baking dish is large enough to accommodate the additional layers and adjust the baking time as needed.
What if I want a healthier version of this gratin?
You can substitute half of the heavy cream with low-fat milk or a plant-based milk. This will reduce calories while maintaining some creaminess.
Conclusion
Once your cheesy root vegetable gratin is baked to perfection, you’ll have a warm, comforting dish that brings joy to any meal. This recipe not only warms the heart but also celebrates the humble root vegetable in a way that appeals to everyone at the table.
