Overview

Creamy Au Gratin Potatoes are a beloved classic that brings warmth and comfort to any table. The dish features layers of thinly sliced russet potatoes, which are known for their starchiness, making them ideal for achieving that creamy texture. The key to a great au gratin is the cheese sauce, and this recipe opts for sharp white cheddar, which not only melts beautifully but also adds a rich flavor profile to the dish.

The preparation begins with melting butter and whisking in flour to create a roux, followed by gradually adding milk to form a smooth sauce. This step is crucial as it sets the foundation for the creamy texture that defines au gratin potatoes. Once the cheese is stirred in, the sauce becomes velvety and irresistible.

Layering the potatoes with the cheese sauce and a sprinkle of salt and pepper ensures that every bite is packed with flavor. Covering the dish with foil during the initial baking phase helps to lock in moisture, allowing the potatoes to cook evenly. The final touch of broiling gives the top a beautiful golden crust, making it visually appealing as well.

This dish is not just a side; it can easily be the star of any meal. Pair it with a juicy steak or a fresh salad for a delightful dinner experience. Whether for a holiday feast or a cozy family dinner, Creamy Au Gratin Potatoes are sure to impress.
