FAQs
Can I use different types of potatoes?
Yes, while russet and Yukon gold potatoes are the most common, you can experiment with red potatoes or fingerlings for different textures and flavors.
How do I know when the gratin is done?
The gratin is done when the top is golden brown and bubbly, and a knife easily pierces the potatoes.
Can I make potato gratin ahead of time?
Absolutely! You can prepare it a day in advance and bake it just before serving. Just add a few extra minutes to the cooking time if it’s cold from the fridge.
