Potatoes Au Gratin Ingredients

For the Gratin
• Unsalted butter (4 tablespoons) – Adds richness to the dish; can substitute with olive oil for a dairy-free option.

Step‑by‑Step Instructions for Potatoes Au Gratin

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). Take a baking dish and generously grease it with 2 tablespoons of unsalted butter, ensuring all the surfaces are coated to prevent the gratin from sticking. This will create a beautifully rich base for your Potatoes Au Gratin.

Step 2: Slice the Potatoes
Using a mandolin or a sharp knife, thinly slice 3 pounds of russet potatoes into even rounds, aiming for about 1/8 inch thick. This uniform thickness is crucial for an even cook and will ensure that your potato layers turn out tender and creamy once baked. Set the sliced potatoes aside in a large bowl.

Step 3: Mix the Creamy Base
In a separate large bowl, combine 1 cup of heavy cream, 1/2 cup of shredded white cheddar cheese, 4 tablespoons of grated Parmesan, and 3 minced garlic cloves. Whisk the mixture until well combined, letting the flavors mingle beautifully. This creamy mixture is the heart of your Potatoes Au Gratin, adding richness and depth.

Step 4: Coat the Potato Slices
Pour the creamy mixture over your sliced potatoes, then gently toss them to ensure each slice is evenly coated. Generously season with salt and pepper as you mix, enhancing the overall flavor of your dish. The potatoes should glisten with the creamy goodness, ready to be layered in the baking dish.

Step 5: Layer the Potatoes
Start layering the coated potato slices in the greased baking dish, standing them upright for a stunning presentation. Arrange them closely but evenly to create a beautiful, organized look. This stacking will help the potatoes cook evenly and absorb all the rich flavors from the cream and cheese mixture.

Step 6: Top with Remaining Cream
Once all the potato slices are arranged, pour any remaining creamy mixture over the layered potatoes. Lightly sprinkle some extra salt and pepper on top, then dot with the remaining 2 tablespoons of butter, distributing it evenly to enhance the flavor and create a crispy crust.

Step 7: Cover and Bake
Cover your baking dish tightly with aluminum foil to trap steam, which will help the potatoes cook thoroughly. Bake for 35-40 minutes in the preheated oven, keeping an eye out for the edges bubbling as the potatoes soften. This initial baking step is key for achieving tender layers in your Potatoes Au Gratin.

Step 8: Uncover and Brown
After the initial baking time, carefully remove the foil, revealing your creamy gratin. Sprinkle the remaining 2 tablespoons of Parmesan cheese evenly over the top, then bake uncovered for another 25-30 minutes. Watch for a beautiful golden crust and ensure the potatoes are fork-tender for the perfect finish.

Step 9: Broil for a Crispy Finish
For the final touch, switch your oven to broil on high for 1 minute. This step will give your Potatoes Au Gratin that delectable crispy topping that contrasts wonderfully with the creamy layers below. Keep a close eye to avoid burning, and remove them once the top is golden brown.

Step 10: Cool and Serve
Once removed from the oven, allow the Potatoes Au Gratin to cool for 10 minutes before serving. This resting time enhances the dish’s flavors and makes it easier to slice while retaining its wonderful creamy texture. Serve warm alongside your favorite main course for a comforting addition to your meal.
