What is a Gratin?
Before we get into the recipe, let’s first understand what a gratin is. A gratin is a culinary term used to describe a dish that is topped with a golden, crispy layer of cheese, breadcrumbs, or both. Typically baked in a shallow dish, gratins are often used to prepare vegetables, potatoes, or even meats, and are usually served as side dishes. The baking process allows the ingredients to meld together, creating a rich and flavorful dish with a beautifully crisp topping.
The French are credited with popularizing gratins, particularly through dishes like Gratin Dauphinois (potatoes in cream and cheese) or Gratin Savoyard (potatoes with cheese and stock). However, vegetable gratin recipes are incredibly versatile and allow for a variety of vegetables to shine through, including root vegetables like carrots, parsnips, turnips, and sweet potatoes.
Why Root Vegetables?
Root vegetables are a fantastic choice for a gratin. Their earthy flavors are enhanced by the creamy cheese and rich sauce that accompanies them. Root veggies such as carrots, parsnips, and rutabagas are naturally hearty, making them ideal for a filling gratin. These vegetables also have a lovely texture once roasted, becoming tender on the inside while still maintaining their shape.
Moreover, root vegetables are packed with nutrients and are available year-round, which makes them an accessible and affordable option for many home cooks. If you’re craving something comforting but still want a dish with a healthy edge, root veggies are your go-to.

Key Ingredients for a Cheesy Root Vegetable Gratin
The key to a mouthwatering Root Vegetable Gratin lies in the right combination of ingredients. Here’s a list of the essential components that will help you create this cheesy delight:
1. Root Vegetables
For this recipe, you can use a variety of root veggies. Common choices include:
- Carrots: Sweet and vibrant, carrots add a nice color and natural sweetness to the dish.
- Parsnips: These root veggies have a nutty flavor that complements the creamy sauce.
- Sweet Potatoes: Slightly sweet and dense, they bring an extra richness to the gratin.
- Turnips: Their mild bitterness pairs beautifully with the cheese and cream.
- Rutabagas: They add a slightly peppery flavor to the dish, enhancing the savory taste of the gratin.
Feel free to mix and match these root veggies according to your preferences. The combination of different textures and flavors creates a layered, complex dish.
2. Queijo
Cheese is what makes this gratin irresistible! The cheese not only adds flavor but also contributes to the rich, creamy texture of the gratin. Some good options include:
- Gruyère: A Swiss cheese that melts beautifully, it’s often used in gratin recipes for its nutty, savory flavor.
- Cheddar: Sharp cheddar works wonderfully in gratins, adding a bold, tangy kick.
- Parmesan: For an extra crispy topping and a salty flavor boost.
- Fontina: A creamy, meltable cheese that adds richness to the dish.
A blend of these cheeses will give your gratin depth of flavor and a smooth texture.
3. Cream
A creamy base is essential for any gratin. You can use heavy cream or half-and-half for a rich, velvety texture. For a lighter version, substitute some of the cream with milk, though this will affect the overall richness. You can also add a splash of vegetable broth to enhance the flavor and reduce some of the heaviness.
4. Farinha de rosca
The breadcrumbs are what create that signature crispy crust on top of the gratin. For added flavor, you can use panko breadcrumbs, which are larger and lighter, giving the topping a crispier texture. Toasted garlic breadcrumbs ou herbed breadcrumbs will add a savory twist to the dish.

5. Seasonings and Herbs
The beauty of a vegetable gratin is in the seasoning. Alho, tomilhoe rosemary are classic herbs used in gratin recipes. Salt, pepper, and a pinch of noz-moscada also elevate the flavor, complementing the natural sweetness of the root veggies.
6. Bacon or Beef Bacon (Optional)
For an extra layer of savory goodness, you can add bacon ou beef bacon. Bacon will bring a smoky flavor that pairs wonderfully with the creamy cheese and root veggies. Beef bacon is a great alternative if you’re looking for a different flavor profile or want a non-pork option.
7. Bread Cheese
If you’re looking to add even more cheesy texture, consider using bread cheese, also known as juustoleipa. This Finnish cheese has a firm texture and is known for its ability to create a golden, crispy crust when baked, which makes it a great addition to your gratin.
How to Make a Cheesy Root Vegetable Gratin
Now that we know the essential ingredients, let’s walk through the process of making a Cheesy Root Vegetable Gratin. This recipe is simple to prepare, but the result is an indulgent, comforting dish that’s perfect for any occasion.
Ingredientes
- 3 cups of mixed root vegetables (carrots, parsnips, sweet potatoes, turnips, etc.), peeled and thinly sliced
- 1 ½ cups of shredded Gruyère cheese
- 1 cup of grated Parmesan cheese
- 1 ½ cups of heavy cream
- ½ cup of milk
- 1 tablespoon of butter
- 1 teaspoon of garlic, minced
- 1 teaspoon of fresh thyme
- 1 teaspoon of rosemary
- Sal e pimenta a gosto
- 1 cup of panko breadcrumbs
- ½ cup of cooked bacon or beef bacon, crumbled (optional)
- ½ cup of bread cheese (optional)

Instruções
- Pré-aqueça o Forno
Begin by preheating your oven to 375°F (190°C). Grease a baking dish with butter to prevent sticking. - Prepare the Root Vegetables
Peel and thinly slice the root vegetables. A mandoline slicer is ideal for achieving even slices, but a sharp knife works too. The key is to ensure the slices are uniform in thickness so they cook evenly. - Cook the Cream Sauce
In a saucepan, melt the butter over medium heat. Add the garlic and sauté for about 1 minute until fragrant. Pour in the heavy cream and milk, then stir in the thyme, rosemary, salt, and pepper. Bring the mixture to a simmer, then lower the heat and let it cook for 3-5 minutes, allowing the flavors to meld. - Assemble the Gratin
Layer the sliced root vegetables in the greased baking dish, slightly overlapping each layer. Pour the cream sauce over the vegetables, ensuring they are evenly coated. Sprinkle half of the Gruyère and Parmesan cheeses on top of the vegetables. - Add the Topping
In a small bowl, mix the panko breadcrumbs with the remaining cheese. If you’re using bacon or beef bacon, add it to the breadcrumb mixture. Sprinkle the breadcrumb and bacon mixture over the top of the gratin, then dot the surface with small pieces of bread cheese, if using. - Bake the Gratin
Cover the baking dish with aluminum foil and bake for 40 minutes. After 40 minutes, remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and crispy. - Servir e Saborear
Once baked, remove the gratin from the oven and let it rest for 5 minutes before serving. The vegetables should be tender, and the cheese should have melted into a luscious, gooey sauce.
Tips for the Perfect Root Vegetable Gratin
- Make it Ahead: This dish can be assembled a day ahead. Simply cover the dish with plastic wrap or foil and refrigerate until you’re ready to bake. You may need to extend the baking time if the gratin is cold from the fridge.
- Vary the Vegetables: Feel free to experiment with different root vegetables. Rutabagas, turnips, and even beets can work wonderfully in this gratin.
- Opção Vegetariana: For a vegetarian version, omit the bacon and use vegetable broth instead of cream for a lighter, plant-based alternative.
