Potatoes au gratin is the kind of dish that effortlessly brings comfort to the table. This classic French recipe, often served as a side dish, is known for its creamy, cheesy richness and perfectly golden, crispy top. While it may seem like a dish that requires advanced culinary skills, it’s actually quite simple to prepare once you understand the basics. In this guide, we’ll show you how to make the best potatoes au gratin—deliciously creamy with a perfect balance of flavors.
The Essential Ingredients
To begin, you’ll need a few basic ingredients that are key to the dish’s flavor and texture. Potatoes, of course, are the foundation of this recipe. Yukon Gold potatoes are popular because their creamy texture and slightly buttery flavor enhance the cheese sauce. Russet potatoes can also work, but they tend to be starchier and may result in a slightly different texture.
Next, you’ll need heavy cream and milk. The combination of these two creates the rich, velvety sauce that makes this dish so comforting. For added depth of flavor, butter is essential, and a generous number of garlic adds an aromatic kick. Finally, for the cheese, Gruyère is the traditional choice for potatoes au gratin. Its nutty, savory flavor melts beautifully and gives the dish its signature creamy texture. Add sharp cheddar for added taste.
Preparing The Potatoes
Once you have your ingredients, it’s time to prepare the potatoes. Start by peeling and thinly slicing them. The key to successful potatoes au gratin is ensuring that the potato slices are uniform in thickness. If the slices are too thick, they may not cook evenly, resulting in parts that are undercooked while others are too soft. Using a mandoline slicer can help you achieve uniform slices and save time.
After slicing, it’s a good idea to soak the potatoes in cold water for about 30 minutes. This helps remove excess starch, which can make the dish too gummy. Once soaked, drain the water and pat the potatoes dry with a clean towel.
Making The Creamy Cheese Sauce
The next step in creating the best potatoes au gratin is preparing the creamy cheese sauce. Butter melts in a pot over medium heat. Stir in minced garlic and simmer for a minute until fragrant. Protect garlic from burning.
Add the heavy cream and milk and boil. As it begins to heat up, you can start seasoning with salt, pepper, and a pinch of nutmeg. Nutmeg is a traditional spice in many au gratin recipes and adds a subtle warmth that enhances the richness of the dish.
Add the shredded Gruyère cheese gently to the simmering cream and milk, stirring frequently until the cheese melts and the sauce thickens. Taste and season the sauce. Grated parmesan cheese can be used for a stronger taste.
Layering The Potatoes
Now that you have your sauce ready, it’s time to assemble the dish. Butter a baking dish generously to prevent the potatoes from sticking. Then, begin layering the sliced potatoes in the dish, slightly overlapping each slice. The idea is to create a tight layer of potatoes so that the sauce can seep through all the slices and flavor every bite.
After each layer of potatoes, pour a little of the creamy cheese sauce over the top, ensuring it’s evenly distributed. Continue layering the potatoes and sauce until the baking dish is full. Be sure to finish with a generous layer of cheese sauce on top.
Baking And Finishing Touches
After assembling the dish, foil it and bake it at 375°F (190°C) for 45 minutes. By steaming the potatoes, the foil prevents scorching. Take off the foil after 45 minutes and bake for 20 more minutes until desired golden and crispy. The sauce should be bubbling, and the potatoes should be tender when pierced with a fork.
For an extra crispy finish, you can place the dish under the broiler for a few minutes at the end of the baking time. Just keep a close eye on it so that the top doesn’t burn. The broiler will give the potatoes au gratin that perfect, golden-brown crust that makes every bite even more irresistible.
Serving And Enjoying
Once your potatoes au gratin are done, let them rest for a few minutes before serving. As the sauce sets, it will be simpler to scoop out ideal quantities. Serve this dish as a side with your favorite main courses, whether it’s roast chicken, steak, or even a simple salad.
