Ingredients

For Potatoes Au Gratin:

• 2 pounds russet potatoes, peeled and thinly sliced
• 2 cups heavy cream
• 1 cup whole milk
• 1 cup grated sharp cheddar cheese (or a blend of cheeses like Gruyère and Parmesan)
• 4 tablespoons unsalted butter
• 2 garlic cloves, minced
• 1 teaspoon salt
• ½ teaspoon freshly ground black pepper
• 1 teaspoon fresh thyme (optional, for added flavor)
• 1 teaspoon Dijon mustard (optional, for extra depth of flavor)
• 1 cup grated Parmesan cheese (for topping)
• Fresh parsley or chives for garnish (optional)

Special Equipment

While Potatoes Au Gratin is a relatively simple dish to prepare, having the right tools will make the process smoother and more efficient:

1. Mandoline Slicer or Sharp Knife: A mandoline slicer makes it easy to slice the potatoes thinly and evenly. If you don’t have one, a sharp knife will work well, but be sure to slice the potatoes as evenly as possible for even cooking.
2. Baking Dish: A 9×13-inch baking dish works perfectly for this recipe. A glass or ceramic dish will help you achieve a nice, even bake and provide an attractive serving dish.
3. Large Saucepan: You’ll need a large saucepan to make the creamy sauce. Choose one that’s wide enough to comfortably fit the milk and cream for easy stirring and even heating.
4. Whisk: A whisk is essential for making the sauce, as it helps to combine the cream, butter, and cheese smoothly and evenly.
5. Grater: Freshly grated cheese always yields the best flavor, so a box grater or food processor will help you grate the cheese easily.

Step-by-Step Instructions

1. Preheat the Oven and Prepare the Baking Dish

Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent the potatoes from sticking. This will also help achieve a beautifully golden crust on the edges of your potatoes.

2. Prepare the Potatoes

Peel the russet potatoes and slice them thinly, about 1/8 inch thick. The thinner the slices, the better the potatoes will cook and absorb the creamy sauce. If you have a mandoline slicer, use it for uniform slices. You can also soak the slices in water for a few minutes to prevent them from turning brown before assembling the gratin.

3. Make the Cream Sauce

In a large saucepan, melt the butter over medium heat. Add the minced garlic and cook for about 1 minute, just until fragrant. Be careful not to burn the garlic.

Next, whisk in the heavy cream, whole milk, salt, pepper, and Dijon mustard (if using). Bring the mixture to a simmer, stirring occasionally. Once it starts to simmer, reduce the heat to low and let it cook for another 2-3 minutes. This allows the flavors to meld together.

Remove the saucepan from the heat and stir in the grated cheddar cheese (and Gruyère, if using). Whisk until the cheese is melted and the sauce is smooth and creamy. Taste the sauce and adjust the seasoning if necessary, adding more salt, pepper, or mustard if desired.

4. Assemble the Gratin

Layer the sliced potatoes in the prepared baking dish, overlapping them slightly to create an even layer. Pour a portion of the creamy cheese sauce over the potatoes, ensuring that the sauce is spread evenly. Continue layering the potatoes and sauce until all the ingredients are used up, finishing with a layer of sauce on top.

Sprinkle the grated Parmesan cheese evenly over the top of the gratin to create a golden, crispy crust while baking. If you want an extra crispy top, you can add more cheese or even a bit of panko breadcrumbs for added texture.

5. Bake the Potatoes Au Gratin

Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. After 45 minutes, remove the foil and bake for an additional 20-30 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork. The baking time may vary slightly depending on the thickness of the potato slices and the specific oven you’re using, so check for doneness by testing the tenderness of the potatoes.

6. Cool and Serve

Once the Potatoes Au Gratin is done, remove it from the oven and let it cool for a few minutes before serving. This allows the sauce to set slightly, making it easier to cut and serve. Garnish with fresh parsley or chives for a burst of color and a fresh, herby note.

Serve the gratin alongside your favorite main dishes—roast meats, seafood, or even a simple salad. The creamy, cheesy potatoes will complement virtually any meal.

Tips for Perfect Potatoes Au Gratin

• Use Starchy Potatoes: Russet potatoes are the best choice for this dish because they’re starchy, which helps create a creamy texture. Waxy potatoes, such as red potatoes, will hold their shape better but won’t absorb the sauce as well.
• Slice Potatoes Evenly: Consistency in potato slice thickness ensures that they cook evenly. A mandoline slicer is great for this purpose, but a sharp knife will work as well if you’re careful to make uniform slices.
• Soak Potatoes: If you’re slicing the potatoes ahead of time, soak them in cold water to prevent browning. This will also help remove excess starch, which can make the dish too gummy.
• Use Freshly Grated Cheese: Pre-grated cheese often contains anti-caking agents that can affect the texture and flavor of the sauce. For the best results, always grate your cheese fresh.
• Don’t Skip the Resting Time: Let the gratin rest for a few minutes after baking. This allows the sauce to thicken up and makes it easier to slice and serve.

Variations of Potatoes Au Gratin

• Garlic Herb Potatoes Au Gratin: Add minced garlic and fresh herbs like rosemary or thyme to the cream sauce for extra flavor. You can also sprinkle more herbs on top before baking.
• Bacon and Cheddar Potatoes Au Gratin: For an extra savory twist, incorporate crumbled cooked bacon into the layers of potatoes or mix it into the sauce for a smoky flavor.
• Vegetarian Potatoes Au Gratin: For a lighter version, you can replace the heavy cream with a mixture of milk and vegetable broth. You can also add vegetables like spinach, mushrooms, or leeks to the layers for added flavor and texture.
• Spicy Potatoes Au Gratin: Add a pinch of cayenne pepper or chili flakes to the cream sauce for a spicy kick. Pair this with a spicy main dish for a bold flavor combination.
• Cheese Variations: While cheddar is the classic cheese used in Potatoes Au Gratin, you can experiment with other cheeses. Gruyère, mozzarella, or fontina create deliciously gooey and flavorful layers, and a mix of cheeses will give the dish more complexity.

Storage and Shelf Life

Potatoes Au Gratin can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, place the gratin in an oven-safe dish and cover with aluminum foil. Bake at 350°F (175°C) for about 20-25 minutes, or until heated through.

For longer storage, you can freeze the dish. To freeze, let the gratin cool completely, then cover tightly with plastic wrap and aluminum foil. Frozen Potatoes Au Gratin can be stored for up to 2-3 months. To reheat from frozen, bake in a preheated oven at 375°F (190°C) for about 45 minutes, then uncover and bake for another 10-15 minutes until bubbly and golden.

Side Dishes and Pairings for Potatoes Au Gratin

Pair Potatoes Au Gratin with complementary dishes to round out your meal:

• Roast Meat: Potatoes Au Gratin pairs wonderfully with roasted meats like beef, chicken, or lamb. The creamy potatoes help balance the richness of the meat.
• Green Salad: A fresh, crisp salad with a tangy vinaigrette can provide a refreshing contrast to the richness of the potatoes.
• Steamed Vegetables: Lightly steamed vegetables such as broccoli, asparagus, or green beans complement the creamy potatoes while adding color and freshness to the plate.
• Red Wine: A glass of red wine, such as Pinot Noir or Merlot, pairs nicely with the richness of the gratin.
