Creamy, Cheesy Potatoes au Gratin
Potatoes au gratin—a name that instantly brings to mind comfort and elegance. But what exactly does “au gratin” mean? This French culinary term refers to a dish baked with a golden, crispy topping, typically made of breadcrumbs or cheese. In this case, it’s all about the cheese! Layers of thinly sliced potatoes are lovingly smothered in a rich, creamy cheese sauce, then baked to bubbly, golden perfection.
You might be wondering how potatoes au gratin differs from scalloped potatoes. While both dishes feature tender potatoes baked in a creamy sauce, scalloped potatoes traditionally skip the cheese, relying on cream or milk for richness. Potatoes au gratin takes things to the next level by adding a generous amount of cheese to the mix, making it the ultimate indulgence for cheese lovers.
Whether you’re serving this as a holiday side or a hearty addition to weeknight dinners, potatoes au gratin never fail to impress. It’s the kind of dish that brings people together, gathering around the table for seconds (or thirds).

What Makes These the Best Potatoes au Gratin?
When it comes to potatoes au gratin, not all recipes are created equal. The best recipes feature perfectly cooked, tender slices of potato, coated in a luscious, creamy cheese sauce. What sets this recipe apart is its simplicity and reliability—no need for complicated techniques or hard-to-find ingredients.
We use Yukon Gold potatoes for their buttery flavor and ability to hold their shape during baking. Yukon Gold potatoes have higher moisture content than Russet potatoes, giving them a naturally creamier texture which means, of course, creamier tasting potatoes.
The sauce, a blend of sharp cheddar cheese, milk, and a touch of garlic, creates the perfect harmony of flavors. And the secret to the golden crust? A final sprinkle of cheese, baked to perfection in the oven.
Tips for Perfect Easy Potatoes au Gratin
Even a simple recipe like this one can be elevated with a few helpful tips. Here’s how to ensure your potatoes au gratin turn out perfect every time:
- Slice Potatoes Evenly: Uniform slices are key to even cooking. Use a mandoline slicer or a sharp knife to achieve consistent thickness—aim for about 1/8 inch.
- Choose the Right Cheese: Sharp cheddar is a classic choice, but feel free to mix in Gruyère or Parmesan for added depth of flavor.
- Layer Thoughtfully: Alternate layers of potatoes and cheese sauce evenly for balanced flavors in every bite.
- Cover, Then Uncover: Bake covered for the first half of the cooking time to ensure the potatoes cook through. Then uncover to achieve a bubbly, golden top layer.
- Let It Rest: After removing the dish from the oven, let it rest for 10–15 minutes. This helps the sauce thicken and the layers set, making serving easier.
