What is Potatoes Au Gratin?
Definition and Origin of Au Gratin
Before diving into what is the difference between Au Gratin and Dauphinoise, it’s essential to understand what Potatoes Au Gratin actually is. Potatoes Au Gratin, also known simply as “Gratin,” is a classic French dish that has gained worldwide popularity. The term “gratin” comes from the French word “gratter,” meaning “to scrape,” which refers to the crispy, golden-brown crust that forms on the top of the dish during baking.
The origins of Potatoes Au Gratin are rooted in the French culinary tradition, where gratin dishes were a way to make simple ingredients more luxurious. Traditionally, Au Gratin dishes are baked in a shallow dish with a topping of breadcrumbs, cheese, and sometimes butter, which creates that signature crust. Potatoes Au Gratin specifically involves layering thinly sliced potatoes in a creamy sauce, usually made with milk, cream, and cheese, and then baking it until bubbly and golden.
Key Ingredients in Au Gratin
The ingredients in Potatoes Au Gratin are relatively simple, but they come together to create a rich and indulgent dish. The primary components include:
- Potatoes: Waxy potatoes like Yukon Gold are preferred for their ability to hold their shape during cooking while absorbing the creamy sauce.
- Cheese: Gruyère, cheddar, or a blend of cheeses is typically used to add a rich, savory flavor.
- Cream and Milk: A combination of heavy cream and whole milk forms the base of the sauce, giving the dish its creamy texture.
- Butter: Used both in the sauce and to grease the baking dish, butter adds richness and flavor.
- Breadcrumbs (optional): Some variations include a breadcrumb topping for extra crunch.
Preparation and Cooking Method
To prepare Potatoes Au Gratin, the potatoes are peeled and sliced thinly, usually about 1/8 inch thick. The slices are then layered in a buttered baking dish, with cheese sprinkled between each layer. The cream and milk mixture, often seasoned with garlic, salt, pepper, and nutmeg, is poured over the potatoes. The dish is then topped with more cheese (and sometimes breadcrumbs) and baked in the oven at around 350°F (175°C) for 45 minutes to an hour, or until the potatoes are tender and the top is golden and bubbly.
Variations and Popular Versions of Au Gratin
While the classic version of Potatoes Au Gratin is beloved for its simplicity, there are numerous variations that incorporate additional ingredients to enhance the flavor. Some popular variations include:
- Potatoes Au Gratin with Ham: Adding diced ham to the layers of potatoes for a heartier dish.
- Garlic and Herb Au Gratin: Infusing the cream with garlic, thyme, or rosemary for added depth.
- Vegetable Gratin: Incorporating vegetables like onions, leeks, or even cauliflower alongside the potatoes.
Each of these variations offers a unique twist on the traditional dish, making it versatile enough for any meal or occasion.
What is Potatoes Dauphinoise?
Definition and Origin of Dauphinoise
Now that we’ve explored Au Gratin, let’s turn our attention to Dauphinoise, another classic French potato dish that often prompts the question: what is the difference between Au Gratin and Dauphinoise? Potatoes Dauphinoise, or “Gratin Dauphinois,” hails from the Dauphiné region in southeastern France. Unlike Potatoes Au Gratin, which can include cheese and breadcrumbs, Dauphinoise is characterized by its simplicity and reliance on just a few key ingredients.
The dish’s name, “Dauphinoise,” reflects its regional origins, and it has been a staple in French cuisine since the 18th century. Dauphinoise is known for its luxurious, creamy texture, achieved by cooking the potatoes slowly in milk or cream until they are tender and infused with flavor.
Key Ingredients in Dauphinoise
The beauty of Dauphinoise lies in its simplicity. The key ingredients are:
- Potatoes: Like Au Gratin, waxy potatoes such as Yukon Gold are ideal.
- Cream: Heavy cream is the primary liquid used, though some recipes may also include milk.
- Garlic: Often used to rub the baking dish and infuse the cream with a subtle flavor.
- Butter: Used to grease the dish and sometimes dot the top before baking.
- Nutmeg and Seasoning: Nutmeg, salt, and pepper are commonly used to season the dish.
Notably, traditional Dauphinoise does not include cheese, which is one of the key differences from Au Gratin.
Preparation and Cooking Method
Preparing Dauphinoise is a straightforward process, but attention to detail is crucial to achieving the perfect texture. The potatoes are peeled and sliced very thinly, often even thinner than for Au Gratin. The slices are typically about 1/16 inch thick, which allows them to cook evenly and absorb the cream.
The baking dish is first rubbed with a cut clove of garlic, infusing it with a delicate garlic flavor. The potato slices are then layered in the dish, with cream poured over each layer. Some recipes call for gently heating the cream with the garlic and seasoning before pouring it over the potatoes.
Dauphinoise is baked at a lower temperature than Au Gratin, typically around 325°F (160°C), for an hour to 90 minutes. The result is a dish with tender, melt-in-your-mouth potatoes and a rich, creamy sauce that is both comforting and elegant.
Variations and Regional Adaptations of Dauphinoise
While the traditional Dauphinoise recipe is cherished for its simplicity, there are also variations that introduce new flavors while maintaining the dish’s creamy texture. Some of these include:
- Truffle Dauphinoise: Incorporating truffle oil or shaved truffles for a luxurious twist.
- Herbed Dauphinoise: Adding fresh herbs like thyme, rosemary, or parsley for a fragrant dish.
- Lightened Dauphinoise: Using a mixture of milk and cream to reduce the richness while retaining flavor.
These variations allow Dauphinoise to be adapted to different tastes and occasions, while still preserving the essence of the dish.
Historical Background of Au Gratin and Dauphinoise
The Culinary History of Au Gratin
To fully appreciate what is the difference between Au Gratin and Dauphinoise, it’s helpful to explore the culinary history of these dishes. The technique of “gratinating,” or creating a browned crust on top of a dish, has its roots in French cuisine and dates back to at least the 17th century. Au Gratin dishes were traditionally a way to make the most of simple ingredients, such as potatoes, by adding a luxurious finish with cheese and breadcrumbs.
Over time, the concept of gratin expanded beyond potatoes to include vegetables, pasta, and even seafood. The use of cheese became more common in the 19th century as dairy products became more accessible. Today, Potatoes Au Gratin is enjoyed worldwide and has become synonymous with comfort food.
The Origin and Evolution of Dauphinoise
Dauphinoise, on the other hand, has a more specific regional origin. The dish is named after the Dauphiné region in southeastern France, an area known for its dairy products and mountain cuisine. The first recorded mention of Gratin Dauphinois dates back to 1788, when it was served at a dinner for the municipal officers of the town of Gap.
The dish was traditionally made with raw potatoes, cream, and sometimes eggs, which were slow-cooked in an earthenware dish. The slow cooking process allowed the potatoes to absorb the cream fully, resulting in a rich, tender dish. Unlike Au Gratin, Dauphinoise does not traditionally include cheese, which is one of the distinguishing factors between the two.
Key Differences Between Au Gratin and Dauphinoise
Comparison of Ingredients: Cheese, Cream, and Potatoes
One of the primary answers to what is the difference between Au Gratin and Dauphinoise lies in the ingredients. While both dishes feature potatoes as the star ingredient, the inclusion of cheese is a significant difference. Potatoes Au Gratin typically includes a generous amount of cheese, either mixed into the dish or layered on top to form a golden crust. Dauphinoise, in contrast, traditionally does not include cheese, focusing instead on the creaminess of the dish.
The type of liquid used also differs. Au Gratin often uses a combination of cream and milk, while Dauphinoise relies solely on cream or a cream-milk blend, which gives it a richer texture.
Cooking Techniques: Baking vs. Layering
The cooking techniques for these dishes also vary. Potatoes Au Gratin involves layering the potatoes with cheese and then baking them with a milk-cream mixture. The baking temperature is usually higher, which helps create a crispy, golden top.
Dauphinoise, on the other hand, is often cooked at a lower temperature for a longer time, allowing the cream to infuse the potatoes fully. The layering in Dauphinoise is also more delicate, with thinner slices of potatoes and no cheese between the layers.
Texture and Flavor Profiles
The textures of these dishes are where you’ll really notice what is the difference between Au Gratin and Dauphinoise. Potatoes Au Gratin has a more varied texture, with a crispy top and tender, cheesy potatoes underneath. The cheese adds a savory depth of flavor that complements the creamy sauce.
Dauphinoise, meanwhile, is all about creaminess. The potatoes are tender and almost melt in your mouth, with the cream creating a luxurious, velvety texture. The flavor is more subtle, allowing the natural sweetness of the potatoes and the richness of the cream to shine through.
Traditional vs. Modern Adaptations
Both Au Gratin and Dauphinoise have seen numerous adaptations over the years. Traditional recipes for each dish are still widely used, but modern cooks have introduced variations to suit different palates and dietary preferences.
For example, some modern Au Gratin recipes include exotic cheeses or the addition of vegetables like broccoli or cauliflower. Similarly, Dauphinoise has seen the introduction of ingredients like garlic, herbs, and even truffles to enhance the dish’s flavor.
Au Gratin vs. Dauphinoise: Which is Healthier?
Nutritional Comparison of the Two Dishes
When considering what is the difference between Au Gratin and Dauphinoise from a nutritional standpoint, both dishes are quite rich, but there are subtle differences. Potatoes Au Gratin, with its cheese and often additional breadcrumbs, is higher in calories and fat compared to Dauphinoise, which relies more on cream.
However, both dishes are indulgent, and their healthiness can depend largely on portion size and the specific ingredients used. Using lighter versions of cream or less cheese can make either dish slightly healthier.
Health-Conscious Modifications
For those looking to enjoy these dishes with fewer calories, there are ways to lighten them up:
- For Au Gratin: Consider using reduced-fat cheese, substituting some of the cream with milk, or even using a vegetable-based sauce.
- For Dauphinoise: You can reduce the richness by using a mixture of milk and cream or by opting for low-fat cream.
These modifications can help reduce the calorie count while still allowing you to enjoy the comforting flavors of these classic dishes.
Considerations for Special Diets (e.g., Gluten-Free, Vegan)
Both Au Gratin and Dauphinoise can be adapted for special diets with a few adjustments:
- Gluten-Free: Both dishes are naturally gluten-free as long as breadcrumbs are omitted from Au Gratin.
- Vegan: For a vegan version, substitute dairy with plant-based milk and cream. Nutritional yeast can be used in place of cheese for Au Gratin.
These adaptations can make these dishes accessible to a wider audience without sacrificing too much flavor.
Common Misconceptions About Au Gratin and Dauphinoise
Misunderstandings in Terminology and Regional Names
One common misconception when discussing what is the difference between Au Gratin and Dauphinoise is the confusion with similar-sounding dishes. For example, some might confuse Au Gratin with scalloped potatoes, another potato dish that’s often baked with cream but without cheese.
Similarly, regional variations can sometimes lead to misunderstandings. In some parts of France, what is called “Gratin” might actually resemble Dauphinoise more closely, depending on local traditions.
Clarifying the Difference Between Similar Dishes (e.g., Scalloped Potatoes)
It’s also important to clarify the difference between Au Gratin and scalloped potatoes. While both dishes involve sliced potatoes baked in a creamy sauce, scalloped potatoes traditionally do not include cheese, making them closer to Dauphinoise. However, the term “scalloped” has been used interchangeably with Au Gratin in some regions, adding to the confusion.
How to Avoid Confusion When Cooking or Ordering
To avoid confusion, it’s helpful to be specific when cooking or ordering these dishes. If you want cheese in your dish, specify that you’re looking for Au Gratin. If you prefer a simpler, cream-based dish, Dauphinoise is the way to go. Understanding what is the difference between Au Gratin and Dauphinoise will help ensure you get exactly what you’re expecting.

Cooking Tips for the Perfect Au Gratin
How to Choose the Right Potatoes
When making Potatoes Au Gratin, the choice of potato is crucial. Waxy potatoes like Yukon Gold are ideal because they hold their shape during baking while absorbing the creamy sauce. Avoid starchy potatoes like Russets, which can become too soft and lose their structure.
Tips for Achieving the Perfect Cheesy Crust
To achieve the perfect cheesy crust on your Au Gratin, it’s important to use the right cheese and baking technique. Gruyère is a popular choice for its melting qualities and rich flavor. To prevent the cheese from burning, cover the dish with foil for the first part of the baking process, then remove the foil to let the top brown.
Avoiding Common Mistakes in Preparation
Common mistakes when making Potatoes Au Gratin include slicing the potatoes too thickly, which can lead to uneven cooking, and using too much liquid, which can make the dish soupy. Slicing the potatoes evenly and using just enough cream to cover the layers will help you achieve the best results.
Cooking Tips for the Perfect Dauphinoise
Choosing the Right Type of Cream
For the creamiest Dauphinoise, heavy cream is the best choice. However, if you prefer a slightly lighter dish, you can use a mixture of cream and whole milk. Be sure to season the cream well with salt, pepper, and a pinch of nutmeg to enhance the flavor.
Techniques for Layering and Baking
The key to a perfect Dauphinoise is thinly sliced potatoes, which should be layered evenly in the dish. To ensure even cooking, avoid overlapping the slices too much. The dish should be baked slowly at a lower temperature, allowing the potatoes to absorb the cream fully and become tender.
Ensuring Even Cooking and Perfect Texture
To ensure even cooking, it’s important to arrange the potato slices in a slightly overlapping pattern, like shingles on a roof. This allows the cream to seep between the layers, ensuring that all the potatoes are evenly cooked. If the top starts to brown too quickly, cover the dish with foil to prevent burning.
Serving Suggestions for Au Gratin and Dauphinoise
How to Present These Dishes Elegantly
When serving Potatoes Au Gratin or Dauphinoise, presentation matters. For a more elegant presentation, consider using individual ramekins instead of a large baking dish. This not only makes for a beautiful presentation but also ensures that each serving has a perfect portion of the crispy top.
Garnishing Ideas
Garnishing your dish can add a touch of color and flavor. For Au Gratin, a sprinkle of fresh herbs like parsley or chives adds a fresh note to the rich dish. Dauphinoise can be garnished with a dusting of nutmeg or a drizzle of truffle oil for an extra touch of luxury.
Serving Temperature and Portioning
Both Au Gratin and Dauphinoise are best served hot, straight from the oven. If you need to prepare them ahead of time, reheat them in the oven to restore their texture and flavor. When serving, consider portioning the dish at the table to ensure that each guest gets a perfect serving of the creamy, crispy potatoes.
