Steps How to Make Au Gratin Potatoes

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C) and position the baking rack in the middle of the oven.

Step 2: Prep the Potatoes

Peel and slice 2-3 pounds of Yukon Gold potatoes thinly and evenly. Rinse the sliced potatoes in cold water to remove any excess starch, then pat them dry with a paper towel.

Step 3: Prepare the Creamy Sauce

In a small saucepan, melt 4 tablespoons of butter over medium heat. Add 4 minced cloves of garlic and sauté for 1 minute until fragrant. Add 4 tablespoons of all-purpose flour and whisk continuously for 1 minute. Gradually pour in 2 cups of whole milk and bring the mixture to a simmer. Cook for 2-3 minutes while whisking continuously until the sauce thickens. Turn off the heat and add 1 teaspoon of salt, 1/4 teaspoon of black pepper and 1/2 teaspoon of dried thyme. Stir well.

Step 4: Layer the Potatoes and Sauce

Layer half of the sliced potatoes in the bottom of a lightly greased 9×13 inch (23×33 cm) baking dish. Pour half of the creamy sauce over the potatoes, spreading it evenly. Top with half of the shredded cheddar cheese. Repeat with another layer of sliced potatoes, sauce and cheddar cheese.

Step 5: Bake

Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. Uncover the dish and continue baking for another 25-30 minutes until the potatoes turn golden brown and the cheese is bubbly. Remove from the oven and let it cool for a few minutes before serving.

Step 6: Garnish and Serve

Garnish the dish with chopped fresh parsley or chives and serve hot.

Explanation How to Make Au Gratin Potatoes

Au Gratin Potatoes is a classic potato dish that originated in French cuisine. The potatoes are thinly sliced and layered with a creamy sauce and cheese, then baked until golden and bubbling. The sauce is made with a roux of butter and flour, which is then whisked with whole milk to create a smooth and creamy mixture. Some recipes call for heavy cream or a combination of milk and cream for a richer sauce.

The type of potatoes used can vary, but Yukon Gold potatoes are a great choice because they are buttery and have a rich flavor. The potatoes should be peeled and sliced into thin, even slices. To get the perfect slices, it is recommended to use a sharp knife or a mandolin slicer. Rinsing the slices in cold water helps to remove the excess starch, which can make the dish gluey.

Cheese is a crucial ingredient in Au Gratin Potatoes. While cheddar cheese is the most commonly used, you can also use Gruyere or Parmesan cheese for a different flavor. The cheese is sprinkled over the layers of potatoes and sauce before baking. Some recipes call for adding breadcrumbs or crushed crackers for extra crunch on top.

When baking the dish, it is important to cover it with foil for the first half of the baking time to prevent the cheese from burning and to allow the potatoes to cook through. Removing the foil for the second half of the baking time helps to brown the cheese and create a crispy top layer.

Tips and Tricks How to Make Au Gratin Potatoes

1. Choose the right type of potatoes

Choosing the right type of potatoes can make a big difference in the final outcome. Yukon Gold potatoes are highly recommended, but you can also use Russet potatoes or red potatoes. Just ensure that they are fresh and free of blemishes.

2. Use a mandolin slicer

A mandolin slicer can help to ensure that your potato slices are uniformly thin. This can make a huge difference in the texture of your dish.

3. Rinse the sliced potatoes

Rinsing the sliced potatoes in cold water can help to remove excess starch and prevent the dish from becoming too gluey.

4. Use heavy cream for a richer sauce

If you want a richer and creamier sauce, you can use heavy cream or a combination of milk and cream instead of whole milk.

5. Experiment with different cheese and toppings

While cheddar cheese is the most commonly used, you can experiment with different types of cheese for a different flavor. You can also add breadcrumbs or crushed crackers for extra crunch on top.

6. Let the dish cool for a few minutes before serving

Au Gratin Potatoes can be very hot when it comes out of the oven. Letting it cool for a few minutes before serving can help you to avoid any accidental burns.

7. Reheat leftovers in the oven

If you have any leftovers, it is best to reheat them in the oven rather than the microwave. This will help to retain the crispy texture and prevent the dish from becoming too soggy.

8. Serve with a green salad or roasted vegetables

Au Gratin Potatoes are a rich and heavy dish, so it is a great idea to serve them with a light and fresh green salad or some roasted vegetables to balance out the meal.

9. Add bacon or ham for a non-vegetarian version

If you are not a vegetarian, you can add cooked bacon or ham for a meaty and flavorful twist on this classic side dish.

10. Make ahead and freeze for later

You can prepare Au Gratin Potatoes ahead of time and freeze them for later. Simply bake as directed, let them cool completely, then wrap tightly in foil and freeze for up to 3 months. When ready to serve, reheat them in the oven at 350°F (180°C) for around 30 minutes from frozen.
