Step‑by‑Step Instructions for Potatoes Au Gratin

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C) and generously grease a baking dish with 2 tablespoons of softened unsalted butter. This will create a beautiful coating that helps the Potatoes Au Gratin develop that signature crispy top layer. Make sure the dish is well-coated to prevent sticking and ensure smooth serving.

Step 2: Slice the Potatoes
Thinly slice the russet potatoes using a mandolin or a sharp knife to ensure uniform thickness, ideally around an eighth of an inch. This step is crucial for even cooking and texture in your Potatoes Au Gratin. Aim for about 16-20 slices to create those creamy layers, and set them aside in a bowl to maintain moisture.

Step 3: Mix the Creamy Base
In a large mixing bowl, combine the heavy cream, shredded white cheddar cheese, 4 tablespoons of grated Parmesan cheese, and the minced garlic. Stir the ingredients together until well combined, forming a rich and cheesy sauce that will envelop the potatoes. This creamy mixture is essential for achieving that luxurious texture in your Potatoes Au Gratin.

Step 4: Coat the Potatoes
Add the sliced potatoes to the cheese mixture in the bowl, gently tossing them until each slice is thoroughly coated. Ensure the potatoes are generously seasoned with salt and pepper as you mix to enhance flavors. The layered potatoes will soak up the creamy goodness, which will be the heart of your finished dish.

Step 5: Layer in the Baking Dish
Begin layering the coated potato slices upright in the greased baking dish, fanning them out for visual appeal. Continue layering until all the potatoes are used up, ensuring an even distribution for consistent cooking. This step not only looks beautiful but allows the flavors to meld perfectly as the Potatoes Au Gratin bakes.

Step 6: Pour the Cream Mixture
Once the potatoes are arranged, pour the remaining cream and cheese mixture evenly over the layered potatoes. Make sure every slice gets a nice coating of the cheesy goodness. Dot the top of the arrangement with the remaining 2 tablespoons of butter to enhance richness and help create that coveted crispy crust.

Step 7: Bake Covered
Cover the dish tightly with aluminum foil to trap steam as it bakes in the oven. Bake for 35-40 minutes until the potatoes are tender. This steaming process allows the potatoes in your Potatoes Au Gratin to soften beautifully before the top has a chance to brown.

Step 8: Broil for a Crispy Top
Remove the foil and sprinkle any leftover Parmesan cheese evenly across the top of the dish. Return it to the oven and bake uncovered for another 25-30 minutes, or until the top is golden and bubbling. If you’re craving that extra crispy topping, broil on high for 1 minute at the end to achieve perfection.

Step 9: Cool Before Serving
Once baked to perfection, allow the Potatoes Au Gratin to cool for about 10 minutes before serving. This cooling period helps the layers settle, making it easier to slice and serve. The creamy, cheesy layers will be inviting and ready to warm hearts at your dinner table.

Expert Tips for Potatoes Au Gratin

Even Slices Matter: Ensure potato slices are uniform in thickness for even cooking; a mandoline is ideal for this task.

Proper Coating: Make sure each potato slice is thoroughly coated with the cream mixture to prevent any dryness in your Potatoes Au Gratin.

Steam Game: Cover your dish tightly with foil during the initial baking to help the potatoes steam and soften perfectly before browning.

Don’t Skip the Broiling: Broil at the end for that irresistible crispy top; just keep an eye on it to avoid burning.

Rest Time: Allowing the dish to cool for 10 minutes before serving helps the layers set and makes slicing easier.

Make Ahead Options

Preparing your Potatoes Au Gratin ahead of time is a dream for busy home cooks! You can assemble the entire dish up to 24 hours in advance; simply layer the potatoes and cover the baking dish tightly with foil before refrigerating. For optimal taste and texture, keep the cream mixture on the side until you’re ready to bake. When you’re ready to serve, pour the cream mixture over your layered potatoes, bake as directed, and add an extra 5-7 minutes to the cooking time if baking straight from the fridge. This make-ahead option means you can enjoy a comforting side dish with minimal effort, letting you spend more time with family and less in the kitchen!
