The world of cuisine is rich with dishes that have similar names but distinct preparations, leading to confusion among cooking enthusiasts and professionals alike. Two such dishes that often spark debate are au gratin and scalloped potatoes. While both are beloved for their creamy, cheesy goodness, they have unique histories, ingredients, and cooking methods. In this article, we will delve into the differences and similarities between au gratin and scalloped potatoes, exploring their origins, recipes, and the cultural contexts in which they are enjoyed.
Introduction to Au Gratin and Scalloped Potatoes
Au gratin and scalloped potatoes are two popular side dishes that originated in different parts of the world. Au gratin is a French culinary term that refers to a dish topped with a crust of buttered breadcrumbs or cheesy sauce, then baked or broiled until golden brown and crispy. This technique is not limited to potatoes; it can be applied to a variety of vegetables, meats, and seafood. On the other hand, scallop refers to a dish made with thinly sliced ingredients, usually potatoes, layering them in a casserole with cream or cheese, and then baking until the top is golden and the sauce is bubbly.
Origins and History
Au Gratin Origins
The term “au gratin” comes from the French language, where “gratin” refers to the crust that forms on top of a dish during baking. The history of au gratin dishes dates back to the 18th century in France, where cooks would use the technique to add texture and flavor to leftover food by topping it with a layer of breadcrumbs and cheese, then baking it in the oven. Au gratin potatoes, in particular, became a favorite among the French culinary repertoire, offering a simple yet elegant side dish for any meal.
Scalloped Potatoes Origins
Scalloped potatoes have their roots in European cuisine as well, although the exact country of origin is less clear. The term “scallop” in cooking originally referred to the shell of the scallop mollusk, which was used as a mold for various dishes. Over time, the term came to describe dishes prepared with thinly sliced ingredients, arranged in a neat, overlapping pattern reminiscent of the scallop shell. Scalloped potatoes were a staple in many European and American households by the mid-20th century, prized for their ease of preparation and comforting, hearty flavor.
Differences in Preparation and Ingredients
While both au gratin and scalloped potatoes are baked dishes that feature potatoes as the main ingredient, there are significant differences in their preparation and ingredients. Understanding these differences is key to mastering each dish and appreciating their unique qualities.
Au Gratin Preparation
Au gratin potatoes are typically made by thinly slicing potatoes and layering them in a baking dish with cheese, cream, and seasonings. The dish is then topped with a mixture of grated cheese and breadcrumbs, which forms a crispy, golden crust during baking. The layering of ingredients in au gratin is less uniform compared to scalloped potatoes, and the use of a substantial amount of cheese and cream gives the dish a rich, luxurious texture.
Scalloped Potatoes Preparation
Scalloped potatoes, on the other hand, are characterized by a precise, overlapping arrangement of thinly sliced potatoes in a casserole dish. The dish is usually made with a simpler sauce of milk or cream, butter, and sometimes cheese, which is poured over the potatoes before baking. The key to scalloped potatoes is achieving a smooth, creamy sauce that complements the tender potatoes without overpowering them. The top of the dish may be sprinkled with additional cheese or breadcrumbs for added flavor and texture.
Cultural Significance and Variations
Both au gratin and scalloped potatoes have undergone numerous variations and adaptations as they spread across different cultures and culinary traditions. These variations not only reflect local tastes and ingredients but also the versatility and appeal of the dishes themselves.
Variations of Au Gratin
Au gratin dishes can be found in various forms around the world, from French recipes that emphasize the use of high-quality cheese and cream to more rustic, peasant-style dishes in Eastern European cuisine that rely on simpler ingredients and heartier portions. In the United States, au gratin potatoes are often enriched with additional ingredients like garlic, bacon, or chives, reflecting the country’s penchant for bold flavors and abundant portions.
Variations of Scalloped Potatoes
Scalloped potatoes have also been adapted in countless ways, from traditional British recipes that focus on the simplicity of potatoes, milk, and butter to more extravagant versions in American cuisine that add ham, bell peppers, or a crunchy topping of fried onions. The dish has become a staple at family gatherings and holidays, where its comforting, familiar flavors are especially welcomed.

Understanding these differences allows cooks to appreciate the unique qualities of each dish and to prepare them with accuracy and flair.

What is the main difference between Au Gratin and Scalloped Potatoes?
The main difference between Au Gratin and Scalloped Potatoes lies in the preparation method and the ingredients used. Au Gratin potatoes are thinly sliced and layered in a dish with cheese, cream, and seasonings, then baked until golden brown and crispy on top. The cheese and cream create a rich, creamy sauce that infuses the potatoes with flavor. In contrast, Scalloped Potatoes are also layered, but they often include additional ingredients like onions, ham, or bell peppers, and the sauce is typically made with a mixture of milk, butter, and flour.
The resulting texture and flavor of the two dishes are also distinct. Au Gratin potatoes have a creamy, cheesy topping with a crispy, caramelized crust, while Scalloped Potatoes have a more rustic, homey feel with a saucy, slightly thickened consistency. The use of cheese and cream in Au Gratin potatoes gives them a more luxurious, sophisticated taste, whereas Scalloped Potatoes are often associated with comfort food and hearty, homestyle cooking. Understanding these differences can help cooks choose the right recipe to suit their taste preferences and the occasion.
How do the slicing methods differ between Au Gratin and Scalloped Potatoes?
The slicing method for Au Gratin potatoes typically involves very thin, uniform slices, often made using a mandoline or sharp knife. This thinness allows the potatoes to cook evenly and quickly, and helps to create the signature crispy, golden-brown crust on top. In contrast, Scalloped Potatoes can be sliced to a slightly thicker width, and the slices may be more rough or uneven. This thicker slicing can help the potatoes hold their shape and retain some texture, even after cooking.
The slicing method also affects the overall texture and presentation of the finished dish. Thin slices of potato, as used in Au Gratin, will break down somewhat during cooking and form a creamy, cohesive mass. Thicker slices, on the other hand, will retain more of their individual texture and structure, resulting in a dish with more visual and tactile appeal. By choosing the right slicing method, cooks can create the desired texture and appearance for their Au Gratin or Scalloped Potatoes, whether that’s a smooth, creamy casserole or a more rustic, chunky side dish.
Can I use the same type of cheese for both Au Gratin and Scalloped Potatoes?
While it’s technically possible to use the same type of cheese for both Au Gratin and Scalloped Potatoes, the traditional and most flavorful choices do differ between the two dishes. Au Gratin potatoes are typically made with a combination of grated cheese, such as Gruyère, Parmesan, or a blend of Swiss and Cheddar. These cheeses have a rich, nutty flavor and a smooth, creamy texture that melts beautifully and adds depth to the dish. Scalloped Potatoes, on the other hand, might use a milder cheese like Cheddar or Monterey Jack, which provides a creamy, melty texture without overpowering the other flavors in the dish.
However, feel free to experiment with different cheese combinations to find the flavor you enjoy the most. Some recipes might call for a blend of cheeses, such as mixing a sharp Cheddar with a milder Colby or a sprinkle of Parmesan for added depth. The key is to balance the flavors and textures so that the cheese complements the potatoes and other ingredients without overwhelming them. Whether you’re making Au Gratin or Scalloped Potatoes, the cheese should enhance the overall flavor and texture of the dish, rather than dominating it.
Do Au Gratin and Scalloped Potatoes have different cooking times and temperatures?
Yes, the cooking times and temperatures for Au Gratin and Scalloped Potatoes can differ, depending on the specific recipes and the desired outcomes. Au Gratin potatoes are often cooked at a higher temperature, around 400°F (200°C), to create a crispy, golden-brown crust on top. This can take about 20-30 minutes, depending on the thickness of the potato slices and the amount of topping. Scalloped Potatoes, on the other hand, might be cooked at a slightly lower temperature, around 350°F (180°C), for a longer period, such as 45-60 minutes. This helps to prevent the top from burning and ensures that the potatoes are cooked through and the sauce is heated and bubbly.
The cooking time and temperature will also depend on the size and shape of the baking dish, as well as the number of servings. A larger dish will require a longer cooking time, while a smaller dish will cook more quickly. It’s essential to check the potatoes periodically during cooking to ensure they’re not overcooking or undercooking. Au Gratin potatoes are done when the top is golden brown and the potatoes are tender, while Scalloped Potatoes are ready when the sauce is bubbly and the potatoes are cooked through. By adjusting the cooking time and temperature, cooks can achieve the perfect texture and flavor for their Au Gratin or Scalloped Potatoes.
Can I add other ingredients to enhance the flavor of Au Gratin and Scalloped Potatoes?
Absolutely, both Au Gratin and Scalloped Potatoes can benefit from the addition of other ingredients to enhance their flavor. Some classic add-ins for Au Gratin potatoes include diced ham, cooked bacon, or caramelized onions, which add a savory, umami flavor to the dish. Garlic, thyme, or rosemary can also be used to add an aromatic, herbal note. For Scalloped Potatoes, ingredients like diced bell peppers, chopped fresh herbs, or grated carrots can add color, texture, and flavor to the dish. Cheese, of course, is a common addition to both recipes, and different types of cheese can be used to create unique flavor profiles.
When adding other ingredients, it’s essential to balance their flavors and textures with the potatoes and other components of the dish. For example, if using a strong ingredient like garlic or onions, start with a small amount and taste as you go, adjusting the seasoning to avoid overpowering the other flavors. Similarly, if adding other vegetables or meats, be sure to cook them until they’re tender and heated through, and adjust the cooking time and temperature as needed to ensure the dish is cooked evenly. By experimenting with different ingredients and flavor combinations, cooks can create unique and delicious variations on both Au Gratin and Scalloped Potatoes.
Are Au Gratin and Scalloped Potatoes suitable for special diets or dietary restrictions?
While traditional recipes for Au Gratin and Scalloped Potatoes often include cheese, cream, and other rich ingredients, it’s possible to adapt these dishes to suit various special diets or dietary restrictions. For example, dairy-free or vegan versions of these recipes can be made using non-dairy milk and cheese substitutes, or by omitting the cheese and cream altogether and focusing on the natural flavors of the potatoes and other ingredients. Gluten-free diets can also be accommodated by using gluten-free flour or cornstarch to thicken the sauce, and by choosing gluten-free seasonings and ingredients.
To make Au Gratin or Scalloped Potatoes more suitable for special diets, consider using healthier ingredients like low-fat milk or reduced-sodium cheese, or adding more vegetables and fiber-rich ingredients to increase the nutrient density of the dish. For low-carb diets, the potatoes can be replaced with cauliflower or other low-carb vegetables, or the portion size can be reduced to minimize the carb content. With a little creativity and experimentation, it’s possible to enjoy delicious, satisfying versions of Au Gratin and Scalloped Potatoes that fit within a variety of dietary restrictions and preferences.
