When it comes to comforting, creamy, and delicious potato dishes, two popular options often come to mind: scalloped potatoes and potatoes au gratin. While both dishes share some similarities, they also have some key differences that set them apart. In this article, we’ll delve into the world of potatoes and explore the history, ingredients, preparation methods, and textures of these two beloved dishes.
A Brief History of Scalloped Potatoes and Potatoes Au Gratin
To understand the differences between scalloped potatoes and potatoes au gratin, it’s essential to look at their origins. Scalloped potatoes have their roots in traditional American cuisine, dating back to the late 19th century. The dish was often served as a side, typically made with thinly sliced potatoes, cream or milk, and cheese, baked in the oven until golden brown.
On the other hand, potatoes au gratin have their origins in French cuisine, specifically in the Dauphiné region. The name “au gratin” refers to the cooking method, where the potatoes are topped with a layer of cheese, cream, or breadcrumbs and baked in the oven until golden and crispy. This technique was popularized in the 18th century and has since become a staple in French cuisine.
Ingredients: What Sets Them Apart
While both dishes share some common ingredients, such as potatoes, cheese, and cream, there are some key differences in the ingredients used.
Scalloped Potatoes
Scalloped potatoes typically consist of:
- Thinly sliced potatoes
- Cream or milk
- Cheese (such as cheddar, Parmesan, or a combination)
- Butter or oil
- Salt and pepper
- Optional: garlic, onion, or herbs for added flavor
Potatoes Au Gratin
Potatoes au gratin, on the other hand, often feature:
- Thinly sliced potatoes
- Cheese (such as Gruyère, Emmental, or Comté)
- Cream or crème fraîche
- Butter or oil
- Salt and pepper
- Optional: garlic, onion, or herbs for added flavor
- A crunchy topping, such as breadcrumbs or grated cheese
One of the main differences between the two dishes is the type of cheese used. Scalloped potatoes often rely on a blend of cheeses, while potatoes au gratin typically feature a single, high-quality cheese, such as Gruyère or Comté.
Preparation Methods: A Tale of Two Techniques
The preparation methods for scalloped potatoes and potatoes au gratin also differ significantly.
Scalloped Potatoes
To make scalloped potatoes, you typically:
- Thinly slice the potatoes and layer them in a baking dish.
- Dot the top of the potatoes with butter or oil.
- Pour cream or milk over the potatoes.
- Sprinkle cheese over the top.
- Bake in the oven until the potatoes are tender and the top is golden brown.
Potatoes Au Gratin
To prepare potatoes au gratin, you:
- Thinly slice the potatoes and layer them in a baking dish.
- Dot the top of the potatoes with butter or oil.
- Sprinkle cheese over the top.
- Pour cream or crème fraîche over the potatoes.
- Top with a crunchy topping, such as breadcrumbs or grated cheese.
- Bake in the oven until the potatoes are tender and the top is golden and crispy.
The key difference in preparation methods lies in the order of the ingredients. Scalloped potatoes typically have the cream or milk poured over the potatoes before adding the cheese, while potatoes au gratin have the cheese sprinkled over the potatoes before adding the cream.
Texture: The Crunchy Truth
One of the most noticeable differences between scalloped potatoes and potatoes au gratin is the texture.
Scalloped Potatoes
Scalloped potatoes tend to be creamy and smooth, with a tender potato texture. The top layer is often golden brown, but it’s not typically crunchy.
Potatoes Au Gratin
Potatoes au gratin, on the other hand, feature a crunchy, golden-brown topping, thanks to the addition of breadcrumbs or grated cheese. The potatoes themselves are tender and creamy, but the topping adds a satisfying textural element.
Conclusion: The Verdict is In
While both scalloped potatoes and potatoes au gratin are delicious and comforting dishes, they have distinct differences in terms of ingredients, preparation methods, and texture. Scalloped potatoes are a classic American side dish, with a creamy, smooth texture and a blend of cheeses. Potatoes au gratin, on the other hand, are a French culinary staple, featuring a crunchy topping and a single, high-quality cheese.
Whether you’re a fan of scalloped potatoes or potatoes au gratin, one thing is certain: both dishes are sure to become a staple in your kitchen. So go ahead, get creative, and experiment with different ingredients and techniques to make these dishes your own.

What is the main difference between scalloped potatoes and potatoes au gratin?
The primary difference between scalloped potatoes and potatoes au gratin lies in the preparation method and the ingredients used. Scalloped potatoes typically involve thinly sliced potatoes layered in a baking dish, topped with cheese, cream, or milk, and then baked until golden brown. On the other hand, potatoes au gratin are also thinly sliced but are cooked in a creamy sauce, often with cheese, butter, and seasonings, before being baked.
While both dishes share similarities, the key distinction lies in the level of creaminess and the cooking technique. Scalloped potatoes tend to be more rustic and straightforward, relying on the natural flavors of the potatoes and toppings. In contrast, potatoes au gratin are often richer and more decadent, with a focus on the creamy sauce and caramelized crust.
Which dish is more popular in the United States?
Scalloped potatoes are generally more popular in the United States, particularly during holidays and family gatherings. This is likely due to the simplicity and familiarity of the dish, as well as its comforting, homey appeal. Many American households have their own version of scalloped potatoes, often passed down through generations.
In contrast, potatoes au gratin are more commonly associated with French cuisine and may be less well-known in some parts of the United States. However, with the increasing popularity of gourmet cooking and international cuisine, potatoes au gratin are gaining recognition and appreciation among American food enthusiasts.
Can I use the same type of potatoes for both dishes?
While it’s possible to use the same type of potatoes for both scalloped potatoes and potatoes au gratin, some varieties are better suited for each dish. For scalloped potatoes, high-starch potatoes like Russet or Idaho work well, as they hold their shape and provide a light, fluffy texture.
For potatoes au gratin, a combination of high-starch and waxy potatoes like Yukon Gold or red potatoes can be used. The waxy potatoes will help maintain their texture and add a touch of sweetness, while the high-starch potatoes will contribute to a creamy, tender consistency.
How do I achieve a crispy, golden-brown crust on my potatoes au gratin?
Achieving a crispy, golden-brown crust on potatoes au gratin requires a combination of proper cooking technique and attention to detail. First, make sure to use a mixture of grated cheese, breadcrumbs, and butter on top of the potatoes. This will provide a crunchy texture and help the crust brown evenly.
To enhance browning, try broiling the potatoes au gratin for a few minutes before serving. Keep a close eye on the dish to prevent burning, and adjust the broiler time as needed. You can also try using a kitchen torch to add a caramelized, golden-brown finish to the crust.
Can I make scalloped potatoes or potatoes au gratin ahead of time?
Yes, both scalloped potatoes and potatoes au gratin can be made ahead of time, but with some caveats. For scalloped potatoes, it’s best to prepare the dish up to the point of baking, then refrigerate or freeze it until ready to bake. This will help prevent the potatoes from becoming soggy or developing off-flavors.
For potatoes au gratin, it’s best to cook the dish completely, then refrigerate or freeze it until reheating. When reheating, add a splash of cream or milk to restore the creamy sauce, and top with additional cheese and breadcrumbs if desired.
Are scalloped potatoes and potatoes au gratin suitable for a vegetarian or vegan diet?
Scalloped potatoes can be easily adapted to a vegetarian or vegan diet by substituting dairy products with plant-based alternatives. Simply replace the cheese with a vegan cheese substitute, and use a non-dairy milk or creamer.
Potatoes au gratin, on the other hand, often rely on dairy products like cheese, butter, and cream for their rich, creamy sauce. However, it’s possible to create a vegan version by using plant-based cheese substitutes, non-dairy milk, and vegan butter or oil.
Can I add other ingredients to scalloped potatoes or potatoes au gratin for added flavor?
Both scalloped potatoes and potatoes au gratin are versatile dishes that can accommodate a variety of ingredients to enhance their flavor. For scalloped potatoes, try adding diced ham, bacon, or cooked vegetables like bell peppers or mushrooms.
For potatoes au gratin, consider adding caramelized onions, roasted garlic, or a sprinkle of fresh herbs like thyme or rosemary. You can also experiment with different types of cheese, such as Gruyère or Parmesan, to add depth and complexity to the dish.
