- Add a sprinkle of Parmesan for extra crispy top.
Mistakes To Avoid

When making French-Style Potato Gratin (Gratin Dauphinois), avoid slicing potatoes too thick, or the layers won’t cook evenly. Don’t skip resting time after baking, or the sauce will be runny instead of creamy. Lastly, avoid using low-fat milk, it makes the gratin less rich and satisfying.
