When it comes to comforting, rich, and flavorful side dishes, potatoes often steal the spotlight. Among the most beloved are au gratin and scalloped potatoes. But what really sets these two classic dishes apart? In this in-depth comparison of au gratin vs scalloped potatoes, we’ll delve into their unique characteristics, from ingredients and cooking techniques to flavor profiles and more. Whether you’re planning your next holiday meal or simply want to impress your guests with culinary knowledge, understanding the differences between au gratin vs scalloped potatoes is essential.
What Are Scalloped Potatoes?
Definition and Origin: Understanding Scalloped Potatoes
Scalloped potatoes, a staple in many American households, feature thinly sliced potatoes baked in a luscious cream sauce. The name “scalloped” likely evolved from the Old English word “collop,” which meant thin slices of meat. Over time, this term adapted to describe the thinly sliced potatoes in this dish.
Ingredients: What Goes into Scalloped Potatoes?
When preparing scalloped potatoes, you’ll use relatively simple yet deeply satisfying ingredients. These include:
- Thinly sliced potatoes (often Russet or Yukon Gold)
- A cream-based sauce made with heavy cream or milk
- Butter and flour to form a roux that thickens the sauce
- Seasonings such as garlic, onion, salt, pepper, and sometimes herbs like thyme or rosemary
Traditional scalloped potatoes do not contain cheese, unlike their cheesy cousin, au gratin potatoes. However, many modern variations introduce cheese into the recipe, blurring the lines between scalloped and au gratin potatoes.
Cooking Method: How to Prepare Scalloped Potatoes
To prepare scalloped potatoes, start by slicing the potatoes thin, usually about 1/8 inch thick. Layer the potatoes in a casserole dish, coating each layer with the rich cream sauce. Then, bake the dish in the oven until the potatoes become tender and the top turns golden brown, a process that often takes around an hour or more.
This method results in a creamy, soft texture with a slightly browned, crispy top—a hallmark of scalloped potatoes. Serve the dish alongside meats such as ham, roast beef, or chicken, making it a versatile and popular side.
What Are Au Gratin Potatoes?
Definition and Origin: The Elegance of Au Gratin Potatoes
The term “au gratin” comes from the French word “gratter,” meaning to scrape or grate, which refers to the grated cheese or breadcrumbs that form a crispy, golden crust on top of the dish. In the context of au gratin vs scalloped potatoes, au gratin potatoes stand out due to their cheese content, generously layered between the potatoes and melted into the cream sauce.
Ingredients: Key Components of Au Gratin Potatoes
Au gratin potatoes elevate the basic idea of scalloped potatoes with the addition of cheese. The essential ingredients include:
- Thinly sliced potatoes (Russet or Yukon Gold are popular choices)
- Heavy cream or milk, similar to scalloped potatoes
- A variety of cheeses, often Gruyere, Cheddar, or Parmesan
- Butter, sometimes used to enhance the sauce’s richness
- Optional breadcrumbs for added texture on the top layer
- Seasonings like garlic, nutmeg, salt, and pepper
Cheese is what truly sets au gratin potatoes apart. Not only does it mix into the sauce, but it’s also sprinkled between the potato layers and often on top, forming a deliciously crispy, golden-brown crust.
Cooking Method: Crafting the Perfect Au Gratin Potatoes
Preparing au gratin potatoes follows a similar process to scalloped potatoes, with the key difference being the inclusion of cheese. Thinly slice the potatoes and layer them in a casserole dish, generously sprinkling cheese on each layer. Pour a cream sauce enriched with more cheese over the layers.
Bake the dish until the potatoes become tender and the cheese melts and browns to perfection. Some recipes suggest adding breadcrumbs on top, which are broiled at the end to create an extra crispy layer.
Key Differences Between Scalloped and Au Gratin Potatoes
Use of Cheese: The Defining Factor in Au Gratin vs Scalloped Potatoes
The most obvious difference between au gratin vs scalloped potatoes lies in the use of cheese. Scalloped potatoes, in their traditional form, do not contain cheese. They rely on a cream sauce thickened with a roux (butter and flour) to achieve their signature creamy texture. In contrast, au gratin potatoes focus on cheese. This dish features layers of potatoes with cheese sprinkled between them and a cheesy, often crispy, top layer.
Cheese not only influences the flavor but also the texture and richness of the dish. Au gratin potatoes tend to be more decadent, with a deeper, more complex flavor due to the variety of cheeses used.
Cooking Techniques: Variations in Preparation
Both dishes involve layering thinly sliced potatoes and baking them, but the preparation techniques can vary. Scalloped potatoes are typically baked in a simple cream sauce, which may include onions and herbs for added flavor. Au gratin potatoes, however, include layers of cheese and may skip the roux, relying on the cheese to thicken the sauce.
The cooking time and temperature might also differ slightly, with au gratin potatoes often requiring a bit longer to ensure the cheese melts thoroughly and the top layer becomes nicely browned and crispy.
Texture and Flavor: Creamy vs. Cheesy
In terms of texture, scalloped potatoes typically turn out creamier and softer, with a smooth, velvety sauce coating the potatoes. Au gratin potatoes, with their cheese, have a slightly firmer texture and a rich, cheesy flavor that can vary depending on the types of cheese used. The top layer of au gratin potatoes often becomes crispy, adding a pleasing contrast to the soft layers beneath.
Appearance: Aesthetic Differences Between Au Gratin vs Scalloped
You can distinguish the two dishes by their top layers. Scalloped potatoes have a more uniform, creamy appearance, with perhaps a slight browning on the top. Au gratin potatoes, however, boast a golden-brown, cheesy crust that is often speckled with crispy breadcrumbs.
Similarities Between Au Gratin and Scalloped Potatoes
Base Ingredients: The Potato Foundation
Despite their differences, au gratin vs scalloped potatoes share several similarities, starting with their base ingredients. Both dishes use thinly sliced potatoes, typically Russet or Yukon Gold, which are favored for their texture and flavor. Both dishes also rely on a cream-based sauce, though the presence of cheese in au gratin potatoes adds a significant twist.
Layering Technique: Building Flavor
Another similarity lies in the layering technique. In both dishes, the potatoes are layered in a casserole dish, which allows the flavors to meld together as the dish bakes. This method ensures that each bite is a perfect combination of soft potatoes and creamy (or cheesy) sauce.
Baking Process: The Importance of Time and Temperature
Both au gratin and scalloped potatoes bake until the potatoes are tender and the sauce is bubbly. The baking process is crucial for achieving the right texture and flavor. While the presence of cheese in au gratin potatoes may require slightly different baking times or temperatures, the overall process remains quite similar.
Popular Variations of Each Dish
Variations of Scalloped Potatoes: Classic to Contemporary
While traditional scalloped potatoes do not include cheese, many modern recipes have introduced it, blurring the lines between au gratin vs scalloped potatoes. Other popular variations might include:
- Cheese-Enhanced Scalloped Potatoes: A hybrid dish that includes a modest amount of cheese, often cheddar, to add a richer flavor without overpowering the creaminess.
- Herb-Infused Scalloped Potatoes: Using fresh herbs like thyme, rosemary, or sage to add a fragrant, earthy flavor to the dish.
- Scalloped Potatoes with Ham: A heartier version that incorporates slices of ham, making it a more filling main dish.
Variations of Au Gratin Potatoes: Creative Takes on a Classic
Au gratin potatoes, with their emphasis on cheese, lend themselves to even more creative variations:
- Garlic and Gruyere Au Gratin Potatoes: A rich, aromatic dish that combines the sharp flavor of Gruyere with the pungency of garlic.
- Bacon and Cheddar Au Gratin Potatoes: Adding crispy bacon pieces and sharp cheddar for a smoky, flavorful twist.
- Vegetable Au Gratin: Incorporating other vegetables like onions, leeks, or even spinach along with the potatoes to create a more complex dish.
Which Dish is Healthier?
Nutritional Comparison: Breaking Down Au Gratin vs Scalloped Potatoes
When comparing the nutritional profiles of au gratin vs scalloped potatoes, the addition of cheese in au gratin potatoes often results in higher calorie and fat content. Scalloped potatoes, on the other hand, are slightly lighter, especially if made with a milk-based sauce rather than heavy cream.
For those watching their calorie intake, scalloped potatoes might be the better option. However, both dishes can be high in carbohydrates, so enjoy them in moderation, especially if serving them with rich main courses like roast meats.
Healthier Alternatives: Lightening Up These Classic Dishes
If you’re looking to make either dish healthier, consider these tips:
- Use Low-Fat Dairy: Opt for low-fat milk or cream to reduce the overall fat content.
- Reduce the Cheese: In au gratin potatoes, use less cheese or choose a lower-fat variety.
- Incorporate Vegetables: Add vegetables like cauliflower or spinach to bulk up the dish while reducing the calorie density.
- Use Whole-Grain Breadcrumbs: If using breadcrumbs in au gratin potatoes, choose whole-grain varieties for added fiber.

Common Misconceptions
Interchangeable Use of Names: Clearing Up the Confusion
One of the most common misconceptions when comparing au gratin vs scalloped potatoes is the interchangeable use of their names. Many people mistakenly refer to scalloped potatoes as au gratin, or vice versa, simply because both dishes involve baked potatoes in a creamy sauce. However, as we’ve discussed, the presence of cheese is the key differentiator, so it’s important to use the correct terminology to describe each dish.
Myths About Preparation: Debunking Common Beliefs
Another common myth is that scalloped potatoes must always be made with cheese or that au gratin potatoes are more difficult to prepare. In reality, both dishes can be simple to make, especially with the right recipe. Also, while traditional scalloped potatoes do not include cheese, many variations do, further complicating the au gratin vs scalloped debate.
