Step‑by‑Step Instructions for Potatoes Au Gratin

Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) and generously grease a 9×13-inch baking dish with 2 tablespoons of softened unsalted butter. This initial step sets the stage for delicious Potatoes Au Gratin while ensuring the layers won’t stick. The buttery aroma will start filling your kitchen as it heats up.

Step 2: Slice the Potatoes
Using a mandoline slicer or a sharp knife, thinly slice the russet potatoes, aiming for about 1/8-inch thickness for even cooking. This is key to achieving the perfect creamy texture in your Potatoes Au Gratin. As you work, keep an eye on the uniformity to ensure they cook through beautifully.

Step 3: Mix the Cheese Sauce
In a large mixing bowl, combine 1 cup of heavy cream, 1/2 cup shredded white cheddar cheese, 4 tablespoons grated Parmesan cheese, and the minced garlic. Stir this mixture until well blended and creamy. The aroma of garlic and cheese will be irresistible, signaling that your sauce is ready for the potatoes.

Step 4: Combine and Season
Add the sliced potatoes to the cheese sauce, stirring gently but thoroughly to coat each piece evenly. Don’t forget to season generously with salt and pepper, enhancing the flavors of your Potatoes Au Gratin. This step ensures each potato slice is flavorful and will contribute to the creamy texture of the dish.

Step 5: Arrange the Potatoes
Layer the potato slices upright in the greased baking dish, stacking them neatly and packing them closely for even baking. Pour the remaining cheese mixture over the potatoes, making sure to coat them well. Finally, dot the top with the remaining 2 tablespoons of butter for a richer crust as it bakes.

Step 6: Bake Covered
Cover the dish tightly with aluminum foil and bake in the preheated oven for 35-40 minutes. This will allow the potatoes to steam and soften, resulting in that tender, creamy texture characteristic of Potatoes Au Gratin. Keep an eye out for bubbling around the edges during this stage.

Step 7: Bake Uncovered
After the initial baking, carefully remove the foil and sprinkle the remaining 2 tablespoons of grated Parmesan over the top. Bake uncovered for an additional 25-30 minutes, or until the potatoes are fork-tender and the top is a beautiful golden brown. This step gives that sought-after crispy texture.

Step 8: Broil for Finish
For the final touch, set your oven to broil and toast the top of the dish for 1 minute, watching closely to avoid burning. This creates a delightful golden crust that adds both texture and flavor to your Potatoes Au Gratin. Once done, remove it from the oven and let it sit for 10 minutes to firm up before serving.

Expert Tips for Potatoes Au Gratin

Even Slices: Use a mandoline slicer for uniformly thin potato slices. This ensures even cooking, giving your Potatoes Au Gratin that ideal creamy consistency.

Steamy Bake: Cover the dish tightly with foil during the first baking phase. This helps the potatoes steam and become perfectly tender.

Careful Broiling: When broiling for that crispy finish, keep a close watch. It only takes a minute to achieve the ideal golden crust, but it can go from perfect to burnt quickly!

Add Flavor: Don’t hesitate to enhance your dish by including fresh herbs or layers of sautéed onions. These add delightful depth to your comforting Potatoes Au Gratin.

Make Ahead: You can prepare this dish a day in advance. Just refrigerate it, and remember to adjust the baking time by an extra 5-7 minutes when you’re ready to cook.

Make Ahead Options

These Potatoes Au Gratin are perfect for meal prep lovers seeking to save time during busy weeknights! You can prepare the entire dish up to 24 hours in advance—simply assemble the potato layers and cheese sauce as instructed, then cover tightly with foil and refrigerate. This method helps preserve the flavors and prevents browning. When you’re ready to serve, just pop them in a preheated oven and bake for a little longer, about 5-7 extra minutes. By prepping ahead, you’ll not only have a hearty dish ready to go but also enjoy the same delicious, creamy comfort with minimal effort!

Potatoes Au Gratin Variations & Substitutions

Feel free to get creative with your Potatoes Au Gratin and customize it to suit your taste preferences or dietary needs!

Dairy-Free: Substitute heavy cream with coconut cream and use dairy-free cheese for a vegan alternative. This option still delivers richness while being entirely plant-based.
Herb-Infused: Add fresh herbs like thyme or rosemary to the cheese sauce for an aromatic twist. Just a few sprigs will elevate the flavor and add a touch of elegance.
Onion Layers: Incorporate thinly sliced onions between the layers of potatoes for added sweetness and depth. The onions caramelize beautifully during baking, enhancing the overall dish.
Cheese Blend: Try a mix of cheeses like Gouda or mozzarella instead of just cheddar. This will give your gratin a unique flavor profile and gooey texture.
Spicy Kick: Add sliced jalapeños or crushed red pepper flakes to introduce some heat. This spicy twist makes for an exciting flavor contrast with the creamy potatoes.
Protein Boost: For a heartier dish, mix in cooked bacon, ham, or sautéed mushrooms. This not only makes it more filling but also adds complexity to the flavor.
