In this article, we will delve into the world of scalloped and au gratin potatoes, exploring their histories, ingredients, cooking techniques, and the key factors that set them apart.
Introduction to Scalloped Potatoes
Scalloped potatoes are a classic comfort food dish that originated in Europe and was popularized in North America. The term “scalloped” refers to the layered arrangement of thinly sliced potatoes in a baking dish, which are then topped with a creamy sauce and baked until golden brown. Scalloped potatoes are known for their rich, velvety texture and mild flavor, making them a staple at family gatherings and holiday meals. The dish typically consists of sliced potatoes, a mixture of butter, flour, and milk, and various seasonings such as salt, pepper, and nutmeg.
History and Evolution of Scalloped Potatoes
The concept of scalloped potatoes dates back to the 18th century, when French and British chefs began experimenting with layered potato dishes. The original recipes called for thinly sliced potatoes, cream, and cheese, which were baked in a slow oven until the potatoes were tender and the top was golden brown. Over time, the recipe evolved, and various ingredients such as onions, garlic, and herbs were added to enhance the flavor. Today, scalloped potatoes remain a beloved dish, with countless variations and creative twists.
Preparing Scalloped Potatoes
Preparing scalloped potatoes is a relatively straightforward process that requires some basic ingredients and kitchen equipment. The key to achieving the perfect scalloped potatoes is to slice the potatoes thinly and evenly, so they cook uniformly. A mixture of butter, flour, and milk is then prepared to create a creamy sauce, which is poured over the layered potatoes. The dish is then baked in a preheated oven until the potatoes are tender, and the top is golden brown. Some recipes may include additional ingredients such as grated cheese, diced onions, or chopped herbs to add flavor and texture.
Introduction to Au Gratin Potatoes
Au gratin potatoes, also known as “potatoes au gratin,” is a French dish that originated in the late 18th century. The term “au gratin” refers to the cooking technique of topping a dish with a layer of cheese or breadcrumbs and baking it in the oven until golden brown and crispy. Au gratin potatoes are known for their rich, creamy flavor and crunchy texture, making them a popular side dish in fine dining restaurants. The dish typically consists of thinly sliced potatoes, cream, cheese, and various seasonings, which are layered in a baking dish and baked until the potatoes are tender and the top is golden brown.

What is the main difference between scalloped and au gratin potatoes?
The primary difference between scalloped and au gratin potatoes lies in the preparation method and the resulting texture. Scalloped potatoes are typically made by layering thinly sliced potatoes in a casserole dish, topped with a creamy sauce, and then baked until the potatoes are tender and the top is golden brown. This method creates a smooth, creamy dish with a soft texture. In contrast, au gratin potatoes involve a more rustic preparation, where the potatoes are also thinly sliced but are then topped with a mixture of cheese, cream, and seasonings, and baked until the top is crispy and golden.
The key to achieving the perfect au gratin potatoes is to ensure that the top layer is sufficiently caramelized, creating a crunchy texture that complements the tender potatoes beneath. This is achieved by using a combination of cheese, such as grated cheddar or parmesan, and cream or milk, which helps to create a rich, velvety sauce. In addition, the use of seasonings like garlic, thyme, or rosemary can add depth and complexity to the dish. By understanding the fundamental differences between scalloped and au gratin potatoes, home cooks can select the preparation method that best suits their tastes and preferences, and create delicious, satisfying side dishes that complement a wide range of meals.
How do I choose the right type of potato for scalloped or au gratin potatoes?
When it comes to selecting the ideal potato variety for scalloped or au gratin potatoes, there are several factors to consider. For both dishes, it’s best to use high-starch potatoes, such as Russet or Idaho, which yield a light, fluffy texture and a delicate flavor. These potatoes will help to create a smooth, creamy sauce and a tender, easy-to-digest final product. Avoid using waxy potatoes, like Red Bliss or Yukon Gold, as they will retain their shape and create a denser, more rustic texture that may not be suitable for these dishes.
In addition to considering the type of potato, it’s also important to think about the size and shape of the potatoes. For both scalloped and au gratin potatoes, it’s best to use potatoes that are uniform in size, so that they cook evenly and consistently. This can be achieved by selecting potatoes of similar diameter, or by cutting larger potatoes into thinner slices or wedges. By choosing the right type and size of potato, home cooks can create delicious, visually appealing scalloped or au gratin potatoes that are sure to impress family and friends.
Can I use leftover potatoes to make scalloped or au gratin potatoes?
While it’s technically possible to use leftover potatoes to make scalloped or au gratin potatoes, it’s not always the best approach. This is because leftover potatoes can be dry and stale, which can affect the texture and flavor of the final dish. However, if you do find yourself with leftover potatoes, you can still use them to make a delicious scalloped or au gratin potato dish. Simply slice or dice the leftover potatoes and layer them in a casserole dish with your chosen sauce and toppings.
To revive leftover potatoes and create a creamy, tender final product, it’s a good idea to add a little extra moisture to the dish. This can be achieved by using a bit more sauce or cream than you would with fresh potatoes, or by adding some extra liquid, such as milk or broth, to the casserole. Additionally, be sure to adjust the cooking time accordingly, as leftover potatoes may cook more quickly than fresh ones. By taking these steps, you can create a tasty and satisfying scalloped or au gratin potato dish using leftover potatoes, and reduce food waste in the process.
What is the best way to prevent scalloped or au gratin potatoes from becoming too brown or burnt?
To prevent scalloped or au gratin potatoes from becoming too brown or burnt, it’s essential to monitor the dish closely during the cooking time. This can be achieved by checking the potatoes every 20-30 minutes, and covering the top with foil if it starts to brown too quickly. Additionally, you can reduce the oven temperature by 25-50 degrees Fahrenheit to slow down the browning process. It’s also a good idea to use a lower oven rack, as this can help to prevent the top from becoming too brown or crispy.
Another way to prevent over-browning is to use a combination of toppings that will help to regulate the browning process. For example, you can sprinkle some grated cheese or breadcrumbs over the top of the potatoes, which will help to create a golden-brown crust while protecting the underlying potatoes from excessive browning. You can also use a mixture of cream and cheese to create a rich, velvety sauce that will help to keep the potatoes moist and prevent them from becoming too brown or dry. By taking these steps, you can create a beautifully cooked scalloped or au gratin potato dish that is golden brown and delicious, without becoming too brown or burnt.
Can I make scalloped or au gratin potatoes ahead of time and reheat them later?
Yes, it’s possible to make scalloped or au gratin potatoes ahead of time and reheat them later, although the results may vary depending on the method you use. For scalloped potatoes, you can prepare the dish up to a day in advance, refrigerate it overnight, and then bake it in the oven until it’s hot and golden brown. For au gratin potatoes, it’s best to prepare the dish just before baking, as the toppings can become soggy if they’re refrigerated or frozen.
To reheat scalloped or au gratin potatoes, it’s best to use a low oven temperature, around 300-325 degrees Fahrenheit, to prevent the potatoes from becoming too brown or dry. You can also add a little extra moisture to the dish, such as cream or milk, to help keep the potatoes tender and creamy. If you’re reheating a refrigerated or frozen scalloped or au gratin potato dish, be sure to check it frequently to ensure that it’s heated through and hot, and adjust the cooking time accordingly. By making scalloped or au gratin potatoes ahead of time and reheating them later, you can enjoy a delicious, convenient side dish that’s perfect for busy weeknights or special occasions.
How can I add extra flavor to my scalloped or au gratin potatoes?
There are many ways to add extra flavor to scalloped or au gratin potatoes, depending on your personal preferences and the occasion. One of the simplest ways to add flavor is to use a variety of seasonings, such as garlic, thyme, or rosemary, which can be sprinkled over the potatoes or added to the sauce. You can also use different types of cheese, such as cheddar, parmesan, or feta, to create a rich, savory flavor. Additionally, you can add some diced ham, bacon, or pancetta to the dish, which will add a smoky, savory flavor to the potatoes.
Another way to add extra flavor to scalloped or au gratin potatoes is to use a flavored sauce or broth, such as a creamy mushroom sauce or a rich chicken broth. You can also add some sautéed vegetables, such as onions, bell peppers, or mushrooms, to the dish, which will add texture, flavor, and nutrients to the potatoes. Finally, you can experiment with different types of milk or cream, such as whole milk, half-and-half, or crème fraîche, which will add a rich, creamy texture to the dish. By adding extra flavor to your scalloped or au gratin potatoes, you can create a delicious, satisfying side dish that’s sure to please even the pickiest eaters.
Can I make scalloped or au gratin potatoes in a slow cooker or Instant Pot?

For slow cooker scalloped potatoes, simply layer the potatoes, sauce, and toppings in the slow cooker, and cook on low for 3-4 hours or high for 1-2 hours. For Instant Pot scalloped potatoes, use the sauté function to cook the onions and garlic, then add the potatoes, sauce, and toppings, and cook on high pressure for 10-15 minutes.
When making scalloped or au gratin potatoes in a slow cooker or Instant Pot, it’s essential to adjust the cooking time and liquid levels accordingly. For example, you may need to add more liquid to the slow cooker or Instant Pot to prevent the potatoes from becoming too dry or brown. Additionally, you can use the slow cooker or Instant Pot to make a variety of scalloped or au gratin potato dishes, such as loaded potatoes with cheese, sour cream, and chives, or Mediterranean-style potatoes with feta, olives, and sun-dried tomatoes.
