For many home cooks and food enthusiasts, the terms “potato gratin” and “dauphinoise potatoes” often get tossed around interchangeably. They both evoke images of creamy, comforting potato dishes, baked to golden-brown perfection. But are they truly the same? The answer, as with many culinary questions, is a bit nuanced. While they share similarities, there are key distinctions that elevate each dish to its own unique status. This article delves deep into the world of these delectable potato preparations, exploring their origins, ingredients, techniques, and ultimately, what sets them apart.
A Deep Dive into Dauphinoise Potatoes
Dauphinoise potatoes, or Pommes de Terre à la Dauphinoise, hail from the Dauphiné region of southeastern France. This dish boasts a rich history, with its first recorded mention dating back to 1788. Its defining characteristic lies in its simplicity and reliance on high-quality ingredients.
The Core Ingredients of Dauphinoise
The traditional dauphinoise recipe calls for just a handful of elements: thinly sliced potatoes, garlic, cream (traditionally whole milk), and salt and pepper. That’s it. No cheese, no stock, just pure, unadulterated potato and creamy goodness. The potatoes are typically peeled (although some modern variations leave the skins on for added texture and nutrients) and sliced very thinly, traditionally using a mandoline for consistent thickness. The garlic is often rubbed on the baking dish to subtly infuse the potatoes with its flavor, rather than being added directly into the cream.
The Dauphinoise Method: A Layered Approach
The preparation of dauphinoise is a labor of love. The thinly sliced potatoes are layered in a buttered baking dish, with each layer seasoned with salt, pepper, and sometimes a whisper of nutmeg. The cream (or milk) is then poured over the potatoes, ensuring that they are almost completely submerged. The dish is then baked in a moderate oven (around 325°F or 160°C) for a considerable amount of time, usually an hour or more, until the potatoes are tender and the cream has thickened and become beautifully browned on top. The key is to allow the potatoes to slowly cook in the cream, absorbing its flavor and creating a velvety texture.
The Absence of Cheese: A Defining Feature
Perhaps the most crucial distinction of dauphinoise potatoes is the absence of cheese. This may come as a surprise to those familiar with potato gratins, which almost always include some form of cheese. The dauphinoise relies solely on the cream and the natural starches of the potatoes to create its rich and creamy texture. This gives it a cleaner, more delicate flavor compared to its cheesy counterpart.
Exploring the World of Potato Gratin
Potato gratin, on the other hand, is a more general term, encompassing a wider range of potato dishes baked with a topping, often including cheese. While it shares similarities with dauphinoise, the key differences lie in the ingredients and variations allowed.
The Versatility of Potato Gratin Ingredients
Unlike the strict ingredient list of dauphinoise, potato gratin is far more flexible. While potatoes are the star, the supporting cast can vary widely. Cheese is almost always present, with Gruyère, Emmental, cheddar, and Parmesan being popular choices. Other common additions include onions, herbs (such as thyme or rosemary), nutmeg, and even bacon or ham for a heartier dish. Some recipes incorporate a béchamel sauce (a white sauce made with butter, flour, and milk) to create an even richer and creamier base.
Potato Gratin Techniques: Adaptability is Key
The method for making potato gratin is also more adaptable than that of dauphinoise. While thinly sliced potatoes are common, the thickness can vary depending on the desired texture. The potatoes are often layered in a baking dish with the other ingredients, and then covered with cream, milk, or béchamel sauce. The cheese is usually sprinkled on top, creating a golden-brown crust during baking. The baking time and temperature can also vary depending on the recipe and the desired level of browning.
The Cheese Factor: A Gratin’s Signature
The presence of cheese is the defining characteristic of a potato gratin. It adds a savory depth of flavor and creates a crispy, golden-brown topping that is irresistible. The type of cheese used can significantly impact the flavor profile of the dish, allowing for endless variations and customization.

Variations and Modern Interpretations
While the classic recipes for dauphinoise and potato gratin remain popular, modern chefs and home cooks have embraced creativity and experimentation.
Dauphinoise Innovations
While traditionally cheese-free, some contemporary variations of dauphinoise incorporate a small amount of cheese, typically Gruyère or Comté, for added richness. Other innovations include adding herbs such as thyme or rosemary to the cream, or using different types of potatoes, such as Yukon Gold or fingerling potatoes. Some chefs also experiment with adding a touch of nutmeg or other spices to enhance the flavor profile. Using a combination of cream and milk can lighten the dish slightly while still maintaining the creamy texture.
Gratin Galore: Endless Possibilities
The world of potato gratin is a playground for culinary creativity. Chefs and home cooks have developed countless variations, incorporating a wide range of ingredients and flavors. Vegetable gratins, featuring ingredients like cauliflower, broccoli, or zucchini, are a popular alternative to potato-based gratins. Sweet potato gratins offer a sweeter, more vibrant flavor profile. And of course, there are countless variations on the classic potato gratin, each with its own unique blend of cheeses, herbs, and other additions. One popular variation is to include caramelized onions for added sweetness and depth of flavor. Smoked cheeses can also add a unique and smoky dimension to the dish.
Serving Suggestions and Pairings
Both dauphinoise potatoes and potato gratin are excellent side dishes, perfect for complementing a variety of main courses.
Dauphinoise Delights: Perfect Pairings
Dauphinoise potatoes, with their delicate flavor and creamy texture, pair well with roasted meats, such as chicken, pork, or beef. They also complement fish dishes, such as salmon or cod. Their subtle garlic flavor makes them a versatile accompaniment to many different cuisines. A simple green salad provides a refreshing contrast to the richness of the potatoes.
Gratin Glamour: Pairing with Panache
Potato gratin, with its richer and more complex flavor profile, is a heartier side dish that can stand up to bolder flavors. It pairs well with grilled steaks, roasted lamb, or even vegetarian dishes like lentil loaf. The choice of cheese used in the gratin can also influence the pairing. For example, a gratin made with Gruyère would pair well with a dry white wine, while a gratin made with cheddar would complement a bolder red wine.
In Conclusion: Appreciating the Nuances
While the terms “potato gratin” and “dauphinoise potatoes” are often used interchangeably, understanding the subtle differences between these two dishes can elevate your culinary skills. Dauphinoise potatoes are a testament to simplicity, relying on high-quality ingredients and a slow-cooking method to create a creamy and flavorful dish. Potato gratin, on the other hand, is a more versatile preparation, allowing for endless variations and customizations. Ultimately, both dishes offer a comforting and satisfying culinary experience. Appreciating the nuances of each dish allows you to choose the perfect potato preparation for any occasion.

So next time you’re planning a meal, consider the flavors and textures you’re aiming for, and choose the potato dish that best complements your culinary vision.
What is the key difference between Potato Gratin and Dauphinoise potatoes?
Potato Gratin and Dauphinoise potatoes are both delicious creamy potato dishes, but the primary difference lies in the inclusion of cheese. Dauphinoise potatoes are traditionally made with thinly sliced potatoes, cream (often infused with garlic), and sometimes milk, but they strictly avoid any cheese. The cream cooks the potatoes, creating a rich and velvety texture.
Gratin potatoes, on the other hand, always include cheese. Typically, Gruyère or Emmental is used, adding a nutty and savory element to the dish. The cheese is often layered throughout the potatoes or sprinkled on top, creating a golden-brown and bubbly crust. This addition of cheese elevates the richness and flavor profile, distinguishing it from the more subtly flavored Dauphinoise.
Can I use milk instead of cream in Dauphinoise potatoes?
While traditionally Dauphinoise potatoes are made with cream, using milk is possible, but it will significantly alter the final texture and richness. The high fat content of cream is essential for creating the characteristic velvety smoothness and prevents the potatoes from drying out during baking. Milk has a lower fat content, so the result may be less decadent and potentially a bit drier.
However, if you choose to use milk, consider using whole milk for a slightly richer result. You might also add a small amount of butter or even a tablespoon of crème fraîche to compensate for the lack of fat from the cream. Adjust the cooking time as needed, as milk may cook faster than cream, and be sure to keep an eye on the moisture level to prevent burning.
Is garlic always included in Dauphinoise potatoes?
Garlic is a very common, almost expected, ingredient in Dauphinoise potatoes, contributing to the dish’s signature flavor. It is typically used to subtly infuse the cream with its aromatic essence. The garlic is often rubbed on the inside of the baking dish and then gently simmered in the cream before the potatoes are added.
However, while widespread, garlic isn’t absolutely mandatory in every Dauphinoise recipe. Some variations might omit it altogether, especially for those who are sensitive to its flavor or prefer a milder taste. In this case, the potatoes rely solely on the cream and salt and pepper for their flavoring. The presence or absence of garlic is a matter of personal preference.
What type of potatoes are best for making either dish?
The best type of potatoes for both Potato Gratin and Dauphinoise potatoes are starchy or all-purpose varieties. These potatoes hold their shape well during baking while also releasing starch, which helps to thicken the cream and create a cohesive texture. Varieties like Russet, Yukon Gold, or Maris Piper are excellent choices.
Waxy potatoes, such as Red Bliss or fingerling potatoes, are generally not recommended because they tend to remain firm and don’t release enough starch. This can result in a dish that lacks the desired creaminess and may have a less pleasant texture. Choosing the right type of potato is crucial for achieving the best results in either dish.
How thin should the potatoes be sliced?
The potatoes should be sliced very thinly, ideally around 1/8 inch or 3 millimeters thick, for both Potato Gratin and Dauphinoise. This ensures that they cook evenly and become tender throughout the baking process. Thin slices also allow the cream to penetrate the potatoes effectively, resulting in a smoother, more integrated dish.
A mandoline is a highly recommended tool for achieving uniform thickness, but a sharp knife can also be used with careful attention. Avoid slicing the potatoes too thick, as this can lead to uneven cooking and a less desirable texture. The thinness of the slices is crucial for the overall success and enjoyment of both Potato Gratin and Dauphinoise potatoes.
Can I prepare either dish in advance?
Both Potato Gratin and Dauphinoise potatoes can be partially prepared in advance, which is convenient for entertaining or meal prepping. You can slice the potatoes and layer them in the baking dish with the cream mixture up to a day ahead of time. Cover the dish tightly with plastic wrap and refrigerate it until you are ready to bake.
However, keep in mind that the potatoes may discolor slightly when exposed to air. To prevent this, you can toss the sliced potatoes with a bit of lemon juice or keep them submerged in the cream mixture. When you are ready to bake, add any cheese (if making gratin) and bake as directed, possibly adding a few minutes to the cooking time since the dish will be starting from a cold temperature.
What are some variations or additions to Potato Gratin?
Potato Gratin is a versatile dish that lends itself well to various additions and flavor enhancements. Besides the traditional Gruyère or Emmental, you can experiment with other cheeses like cheddar, Parmesan, or Fontina, depending on your preference. Adding herbs like thyme, rosemary, or nutmeg can also create different flavor profiles.
Other variations include incorporating vegetables such as caramelized onions, mushrooms, or leeks between the potato layers for added texture and flavor. Some recipes also include bacon or ham for a more substantial and savory dish. Ultimately, Potato Gratin is a blank canvas that allows for creativity and personalization based on your tastes and available ingredients.
