What Techniques Can Make a Simple Gratin Dauphinois Gourmet with a Crispy Top?

If you’re a fan of French cuisine, you’re likely already familiar with the Gratin Dauphinois, a creamy, potato-based dish from the Dauphiné region in southeast France. This dish is a beloved classic, known for its comforting, rich flavors, and its signature crispy top. But how can you elevate it from a simple side dish to a gourmet masterpiece? In this article, we’ll explore techniques that can take your Gratin Dauphinois to a whole new level.

Selecting the Perfect Potatoes

The first step in creating a gourmet Gratin Dauphinois is choosing the right potatoes. Not all potatoes are created equal, and the type you select can greatly influence the outcome of your dish.

Traditionally, the Gratin Dauphinois calls for a starchy variety, such as Russet or Yukon Gold. These potatoes are more absorbent, which allows them to soak up the cream and milk mixture they’re cooked in. However, if you want to give your dish a gourmet twist, consider opting for a more unusual variety, like Purple Majesty or Pink Fir Apple. These varieties have a unique flavor and color, which can add an unexpected twist to your dish.

Whichever type of potato you choose, ensure they’re thinly sliced, roughly 1/8 of an inch thick. If the slices are too thick, they may not fully absorb the cream mixture, leaving your gratin less flavorful than it could be.

Creating a Rich, Creamy Base

A distinctive characteristic of the Gratin Dauphinois is its rich, creamy base. This is typically made with a combination of cream and milk, which is heated with garlic and nutmeg before being poured over the potatoes.

To elevate this base and give it a gourmet touch, consider substituting the regular cream and milk with a more decadent alternative, such as crème fraîche or heavy cream. You could also experiment with infusing the cream mixture with unique flavors, like truffle oil or saffron, for a luxurious twist.

When it comes to seasoning, remember that less is more. This dish is all about highlighting the natural flavors of the ingredients, so avoid over-seasoning. A touch of sea salt, fresh ground pepper, and a hint of nutmeg should suffice.

Mastering the Crispy Top

The pièce de résistance of any Gratin Dauphinois is the crispy, golden top. Achieving this perfect crunch requires two main steps: the right cheese and the right cooking method.

When selecting cheese, opt for a variety that melts well and has a robust flavor. Traditional choices include Comté or Gruyère, but for a gourmet version, consider using a more premium cheese like aged Gouda or a high-quality cheddar.

Once you’ve layered your potatoes and poured over your cream mixture, sprinkle a generous layer of cheese over the top. Then, bake your gratin in a preheated oven at a high temperature. Watch it carefully towards the end of the cooking time to ensure it doesn’t burn.

Adding Gourmet Touches

While the Gratin Dauphinois is a relatively simple dish, there are several ways you can jazz it up to make it more gourmet.

One idea is to add additional layers of flavor. For instance, you could layer thinly sliced onions or leeks between the potato slices, or sprinkle fresh herbs like thyme or rosemary over the top before baking.

You could also experiment with presentation. Instead of serving your gratin in a traditional dish, consider individual ramekins for a restaurant-quality look. Or, use a mandoline to slice your potatoes into a spiral or lattice pattern for an elegant twist.

Exploring Wine Pairings

No gourmet meal is complete without the right wine, and the Gratin Dauphinois is no exception.

A rich, creamy dish like this calls for a wine with enough acidity to cut through the creaminess, and enough body to stand up to the robust flavors. Typically, a white wine from the same region as the dish, such as a Rhône or Burgundy, would be an excellent choice.

However, if you’ve added gourmet touches like truffle or saffron, you might want to select a wine that complements these flavors. A sommelier or knowledgeable wine shop employee can provide valuable guidance in this area.

Ultimately, the goal is to enhance the flavors of the dish, rather than overpower them, so keep this in mind when selecting your wine.

Paying Attention to Cooking Time and Temperature

The optimal cooking time and temperature for your Gratin Dauphinois can greatly impact the final result. If you aim for a gourmet version of the dish, you’ll need to pay close attention to these factors.

For the perfect gratin potatoes, preheat your oven to 190°C (375°F). This relatively high temperature allows the dish to cook evenly and helps create that sought-after crispy top. It’s important to lightly grease your baking dish before adding the potato slices to prevent them from sticking.

Layer your thinly sliced potatoes in the dish, pouring the decadent milk and cream mixture after each layer. This helps the potatoes absorb the cream, enhancing their flavor and giving your potato gratin that creamy texture.

Cover your baking dish with aluminum foil for the first 30 minutes of baking. This helps the potatoes cook evenly without the top layer getting too crispy too soon. After this, remove the foil and cook for another 30 minutes, or until the top is golden brown and the potatoes are tender.

Remember, every oven is different. So, keep an eye on your dish during the final stages of baking to prevent any overcooking or burning. The goal is to have a dish with a crispy top layer of cheese and potatoes that are cooked to perfection.

Serving Up Your Gourmet Gratin Dauphinois

Once your Gratin Dauphinois is ready, let it rest for a few minutes out of the oven. This allows the creamy sauce to thicken slightly and the flavors to meld together. Your potato gratin then becomes a dish that not just tastes divine, but also holds its shape when served.

For a gourmet touch, sprinkle some fresh chopped parsley or chives on top of your Gratin Dauphinois just before serving. This not only adds a pop of color but also a hint of freshness that complements the rich creamy dish.

If you’ve chosen to bake your Gratin Dauphinois in individual ramekins, serve them on a plate with a small salad or some charcuterie. This way, your side dish of potatoes au gratin becomes a main course fit for a gourmet dinner.


Elevating a traditional dish like Gratin Dauphinois to a gourmet level requires thoughtful selection of ingredients, careful preparation, precise cooking techniques, and elegant presentation. By choosing the right potatoes, upgrading the creamy base, mastering the crispy top, adding gourmet touches, and pairing it with the right wine, you can turn this comforting side dish into a culinary masterpiece. Remember, the key is to emphasize and enhance the basic flavors of the dish, rather than overshadowing them. So, the next time you want to impress your guests, why not serve them a gourmet Gratin Dauphinois?
