The creamy, comforting allure of sliced potatoes baked to golden perfection is a universally cherished culinary experience. But, when faced with the terms “scalloped potatoes” and “dauphinoise potatoes,” confusion often arises. Are they simply different names for the same delectable dish? Or do subtle, yet significant, distinctions separate these two potato gratins? Let’s embark on a flavorful journey to uncover the truth, exploring the history, ingredients, preparation methods, and cultural context of each dish to definitively answer this burning question.
Unraveling the Origins: A Historical Perspective
To truly understand the nuances between scalloped potatoes and dauphinoise potatoes, it’s essential to delve into their historical roots. Each dish boasts a unique narrative, shaped by geographical location and culinary traditions.
Dauphinoise Potatoes: A French Classic
Dauphinoise potatoes, or “pommes de terre à la dauphinoise,” hail from the Dauphiné region of southeastern France. This dish boasts a rich history, with the earliest known mention dating back to 1788 during a dinner hosted by the Duke of Clermont-Tonnerre. This suggests that the dish may be older than that, potentially enjoyed by commoners before its presence at such an upscale meal.
The traditional preparation involved thinly sliced potatoes cooked in milk or cream, often with garlic, and baked in a buttered dish until tender and golden brown. Importantly, cheese was not a traditional component of the original dauphinoise recipe. The simplicity of the ingredients allowed the natural flavor of the potatoes to shine through, complemented by the subtle richness of the dairy.
Scalloped Potatoes: A Transatlantic Adaptation
The story of scalloped potatoes is a bit more complex, weaving a path across the Atlantic. While the exact origins are debated, the term “scalloped” generally refers to a dish baked in a creamy sauce. This method isn’t exclusive to potatoes; it can be applied to other vegetables or even seafood.
The term “scalloped potatoes” appeared in American cookbooks in the 19th century. Recipes varied widely, but a common thread involved sliced potatoes baked in a cream or milk-based sauce. Early versions often included butter and flour to thicken the sauce, creating a richer and more substantial dish. Unlike the traditional dauphinoise potatoes, the inclusion of cheese, particularly cheddar, became a common variation in American scalloped potato recipes. In the USA, scalloped potatoes are considered to be a classic comfort food.
Ingredients: The Building Blocks of Flavor
The ingredients used in scalloped potatoes and dauphinoise potatoes are a key differentiator. While both dishes feature sliced potatoes and dairy, the specific type of dairy and the inclusion of other ingredients can significantly impact the final flavor and texture.
Dauphinoise Potatoes: Simplicity Reigns Supreme
The hallmark of dauphinoise potatoes is its simplicity. The core ingredients typically include:
- Potatoes (usually a waxy variety like Yukon Gold or Maris Piper)
- Milk or cream (or a combination of both)
- Garlic
- Butter
- Salt and pepper
The focus is on showcasing the natural flavor of the potatoes and the subtle infusion of garlic. The absence of cheese allows the creamy texture of the potatoes to be the star of the show. Some cooks may include nutmeg for warmth.
Scalloped Potatoes: Embracing Versatility
Scalloped potatoes, on the other hand, tend to be more versatile in terms of ingredients. While variations abound, common components often include:
- Potatoes (Russet potatoes work well due to their starch content)
- Milk or cream
- Butter
- Flour (for thickening the sauce)
- Onion
- Cheese (often cheddar, but other cheeses like Gruyere or Parmesan can be used)
- Salt and pepper
The addition of flour creates a thicker, more decadent sauce, while the inclusion of cheese adds a savory, melty element. The onions provide a subtle sweetness and aromatic depth. Some recipes also include ham or bacon for added flavor and richness.
Preparation Techniques: A Matter of Method
The way scalloped potatoes and dauphinoise potatoes are prepared also contributes to their distinct characteristics. While both involve slicing potatoes and baking them in a creamy sauce, the specific techniques employed differ.
Dauphinoise Potatoes: Mastering the Delicate Balance
Achieving the perfect dauphinoise potatoes requires careful attention to detail. The potatoes must be sliced very thinly, ideally using a mandoline, to ensure even cooking. The sliced potatoes are typically layered in a buttered baking dish, with each layer seasoned with salt, pepper, and grated garlic. The milk or cream is then poured over the potatoes, ensuring they are almost fully submerged.
The dish is baked at a moderate temperature until the potatoes are tender and the top is golden brown. The slow baking process allows the potatoes to absorb the creamy sauce, creating a rich and harmonious flavor. The starch released from the potatoes naturally thickens the sauce, creating a velvety texture.
Scalloped Potatoes: Building Layers of Flavor
Preparing scalloped potatoes often involves creating a roux-based sauce. Butter and flour are cooked together to form a roux, which is then whisked with milk to create a thickened sauce. This sauce is seasoned with salt, pepper, and often other spices like nutmeg or paprika.
The sliced potatoes are layered in a baking dish with the sauce, along with any other desired ingredients like onions, cheese, or ham. The dish is then baked until the potatoes are tender and the cheese is melted and bubbly. The roux-based sauce creates a thicker, more substantial texture compared to the lighter sauce of dauphinoise potatoes.
Texture and Taste: The Sensory Experience
The differences in ingredients and preparation methods result in distinct textures and tastes for scalloped potatoes and dauphinoise potatoes. These sensory experiences are a crucial factor in distinguishing between the two dishes.
Dauphinoise Potatoes: Creamy Elegance
Dauphinoise potatoes are characterized by their creamy, delicate texture. The thinly sliced potatoes become incredibly tender during baking, almost melting in your mouth. The milk or cream infuses the potatoes with a subtle richness, while the garlic adds a hint of savory flavor. The absence of cheese allows the natural sweetness of the potatoes to shine through. The overall impression is one of elegant simplicity.
Scalloped Potatoes: Rich and Comforting
Scalloped potatoes, on the other hand, offer a richer and more comforting experience. The thicker, roux-based sauce creates a more substantial texture, coating the potatoes in a velvety embrace. The addition of cheese adds a savory, melty element that elevates the dish to new heights of indulgence. The onions provide a subtle sweetness and aromatic depth, while other ingredients like ham or bacon contribute a smoky, savory flavor. The overall impression is one of hearty satisfaction.
Cultural Significance and Regional Variations
Beyond the ingredients and preparation methods, the cultural significance and regional variations of scalloped potatoes and dauphinoise potatoes further highlight their distinct identities.
Dauphinoise Potatoes: A French Culinary Treasure

Understanding these differences allows cooks to choose the preparation that best suits their tastes. Whether you prefer the elegant simplicity of dauphinoise potatoes or the hearty richness of scalloped potatoes, both are sure to satisfy.
It’s easy to see how the two dishes are related. Potatoes, some form of dairy, and an oven are all one needs to create something delicious. It’s a testament to the versatility of humble ingredients.
What is the primary difference between scalloped potatoes and dauphinoise potatoes?
The key distinction lies in the ingredients and cooking method. Scalloped potatoes typically involve sliced potatoes baked in a creamy sauce, often made with milk, flour (as a thickener), and butter. Cheese is also a frequent addition, though not always present. The sauce contributes a richness and helps the potatoes cook evenly in the oven, sometimes taking on a slightly drier texture due to the flour.
Dauphinoise potatoes, on the other hand, strictly exclude flour and often cheese (though some modern variations may include it). The essential components are thinly sliced potatoes baked in milk or cream, often infused with garlic and nutmeg. The potatoes cook slowly in the liquid, resulting in a creamy, almost custard-like consistency without the need for any thickening agent.
Does the type of potato matter when making scalloped or dauphinoise potatoes?
Yes, the potato variety significantly impacts the final outcome. For scalloped potatoes, all-purpose potatoes like Yukon Gold are a good choice because they hold their shape well while still releasing some starch to help thicken the sauce. These provide a balance between structure and creaminess, working well with the added flour.
For dauphinoise potatoes, a starchy potato such as Russet or Maris Piper is preferred. Their higher starch content releases into the milk or cream during baking, contributing significantly to the dish’s signature creamy texture. The starch acts as a natural thickening agent, ensuring the sauce is rich and coats the potato slices beautifully, especially as no flour is used.
Is garlic always included in both scalloped and dauphinoise potatoes?
Garlic is a frequent ingredient in dauphinoise potatoes and considered a classic element. It’s typically infused into the milk or cream, imparting a subtle yet distinctive flavor throughout the dish. While the amount of garlic can vary depending on personal preference, its presence is generally expected in a traditional dauphinoise potato recipe.
While garlic can be added to scalloped potatoes, it is not a mandatory or defining ingredient like it is for dauphinoise potatoes. Some scalloped potato recipes call for it, while others don’t. The flavor profile of scalloped potatoes tends to be more neutral, allowing for the addition of other flavorings like onions, herbs, or different types of cheese without garlic overpowering them.
Can you use cheese in dauphinoise potatoes?
Traditionally, authentic dauphinoise potatoes do not include cheese. The creaminess of the dish comes solely from the milk or cream and the starch released from the potatoes themselves. Adding cheese would alter the flavor and texture, moving it further away from the classic recipe. However, purists would argue against its inclusion.
However, many modern variations of dauphinoise potatoes now incorporate cheese, typically Gruyère or Emmental, to add another layer of richness and flavor. While these are popular and delicious, they are technically a deviation from the traditional recipe. Adding cheese transforms the dish into a more decadent and richer version that some may prefer.
What is the ideal thickness for slicing potatoes in each dish?
Potato thickness is a crucial factor in both scalloped and dauphinoise potatoes. For scalloped potatoes, a slightly thicker slice, around 1/8 to 1/4 inch, is recommended. This allows the potatoes to retain some texture and prevent them from becoming completely mushy during baking, especially with the flour in the sauce.
Dauphinoise potatoes require much thinner slices, ideally around 1/16 inch, or as thin as possible. This enables the potatoes to cook evenly in the milk or cream, absorb the flavors, and release their starch to create the desired creamy consistency. Using a mandoline slicer is highly recommended for achieving consistent and paper-thin slices.
How does the cooking time differ between scalloped and dauphinoise potatoes?
Scalloped potatoes typically have a shorter cooking time compared to dauphinoise potatoes, often taking around 45 minutes to an hour at around 375°F (190°C). The sauce helps to expedite the cooking process, and the potatoes don’t need as much time to soften completely, particularly if they’re sliced slightly thicker.
Dauphinoise potatoes, on the other hand, require a longer cooking time, usually around 1 to 1.5 hours at a slightly lower temperature of around 325°F (160°C). This slow cooking allows the potatoes to fully absorb the milk or cream, release their starch, and achieve that characteristic creamy texture without burning the surface.
Can scalloped potatoes be made without flour?
While traditional scalloped potato recipes often include flour as a thickening agent, it is possible to make a version without it. The key is to use a starchy potato variety like Russet or Yukon Gold, and to ensure the potatoes are sliced thinly enough to release their starch into the milk or cream as they cook. Reducing the amount of liquid can also help achieve a thicker sauce naturally.
By omitting the flour, you create a lighter and less dense sauce. The resulting dish will have a creamier texture due to the potato starch acting as the thickener. This approach is a great option for those seeking a gluten-free or lighter version of scalloped potatoes, more closely resembling the texture of dauphinoise potatoes while still retaining other elements like cheese.
