Classic Au Gratin Potatoes for Every Occasion

Au gratin potatoes are a beloved comfort food that combines tender potato slices with a rich, creamy cheese sauce. This classic dish, often reserved for holidays and special occasions, is a delightful accompaniment to a variety of main courses. The hallmark of an exceptional au gratin potatoes recipe lies in achieving the perfect balance between creamy, cheesy goodness and a delectably crispy top layer.

History of Au Gratin Potatoes

The term “au gratin” comes from the French word “gratter,” which means to scrape or grate, referring to the topping of grated cheese or breadcrumbs that becomes beautifully browned when baked. ” This cooking technique originated in France in the 18th century and was initially used to cook vegetables, such as potatoes, carrots, and zucchini, in a creamy sauce topped with breadcrumbs or cheese. The dish is believed to have originated in the Dauphiné region of France, where potatoes were plentiful and often used in cooking. Over time, au gratin potatoes became a popular dish in French cuisine and eventually made their way to dining tables around the world.

What is the difference between Au Gratin Potatoes and Scalloped Potatoes?

Two popular potato side dishes, au gratin, and scalloped potatoes, are both deliciously creamy and hearty. Although similar in nature, au gratin potatoes tend to be sliced more thinly compared to scalloped potatoes. In traditional scalloped potato recipes, cheese is typically omitted, but more modern versions often incorporate cheese into the dish.

What cheese to use?

For a memorable Potatoes au Gratin, use cheese with an assertive flavor such as sharp cheddar (sharp cheddar cheese sauce), parmesan, or Gruyere (or swiss). The rich flavor of Gruyere will give your dish an unbeatable taste. However, if it is not available, provolone or swiss make excellent substitutes.

If you want to get the perfect sauce, the best approach is to grate the cheese from a block. While pre-shredded cheeses may be convenient, they will not melt as nicely.

While cheddar is the traditional choice, variations with Parmesan, Gruyère (Mornay Sauce), or a mix of cheeses can offer a unique twist to the classic recipe. The addition of herbs and spices, such as smoked paprika or nutmeg, can elevate the flavor profile, making each bite more intriguing.

Choosing the Right Potatoes

The best potatoes for Au Gratin are starchy varieties that hold their shape well when cooked. Some popular choices include:

• Russet potatoes: These are a classic choice for Au Gratin Potatoes. They have a high starch content, which gives them a fluffy texture.
• Yukon Gold potatoes: These potatoes have a slightly buttery flavor and a creamy texture. They are a good choice for those who prefer a milder flavor.
• Fingerling potatoes: These small potatoes are often used for Au Gratin Potatoes because they cook quickly and evenly.

Ingredients for Au Gratin Potatoes

For the Potatoes:

• 4 large russet potatoes (or Yukon Gold for a creamier texture), thinly sliced
• Salt and pepper, to taste

For the Creamy Sauce:

• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1 1/2 cups whole milk
• 1 cup heavy cream
• 1 clove garlic, minced
• 1 teaspoon thyme (fresh or dried)
• Pinch of nutmeg (optional)
• 1 cup grated Gruyère cheese (or cheddar, Parmesan, or a mix)

Step-by-Step Instructions

1. Preheat Your Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

2. Prepare the Potatoes

Peel the potatoes and slice them thinly—about 1/8 inch thick. A mandoline slicer is ideal for achieving uniform slices, which ensures even cooking.

3. Make the Creamy Sauce

1. Melt the butter in a medium saucepan over medium heat.
2. Add the minced garlic and sauté for 1 minute until fragrant.
3. Whisk in the flour to form a roux. Cook for 1-2 minutes, stirring constantly, until lightly golden.
4. Gradually pour in the milk and cream, whisking continuously to avoid lumps.
5. Add thyme, nutmeg, salt, and pepper to taste. Simmer for 3-4 minutes until the sauce thickens.
6. Stir in the Gruyère cheese until melted and smooth. Remove from heat.

4. Assemble the Dish

1. Arrange a layer of sliced potatoes in the prepared baking dish, slightly overlapping.
2. Pour a portion of the creamy sauce over the potatoes, spreading it evenly.
3. Repeat the layers until all the potatoes and sauce are used, making a layer of sauce on top.
4. Sprinkle a final layer of grated cheese on top.

5. Bake

Cover the dish with aluminum foil and bake for 40 minutes. Remove the foil and bake for an additional 20-30 minutes until the top is golden brown and the potatoes are tender when pierced with a fork.

6. Let It Rest

Allow the au gratin potatoes to cool for 10 minutes before serving. This helps the dish set and makes it easier to serve.

Avoiding Common Mistakes

First, ensure your potatoes are sliced uniformly. Uneven slices can result in inconsistent cooking, leaving some pieces undercooked while others turn mushy. A mandoline slicer is a useful tool for achieving thin, even slices.

Be careful with the sauce. Adding cheese to the cream too quickly can cause it to clump. Gradually whisk in the cheese over low heat, allowing it to melt completely before adding more. This will help you achieve a smooth, creamy sauce.

Avoid using too much liquid. While it may seem tempting to add extra cream for a richer dish, this can lead to a runny consistency. Stick to the recommended amount of cream and let the sauce thicken properly before layering it with the potatoes.

Don’t forget to season adequately. Potatoes can be quite bland without proper seasoning. Adding salt and pepper to the cheese sauce ensures that every layer is flavorful. You can also experiment with herbs and spices, but be careful not to overpower the dish.

When baking, keep an eye on the timing and temperature. Baking covered for too long can make the dish soggy, while uncovering it too soon can dry it out. Follow the recommended baking times closely and adjust based on your oven’s performance.
