FAQs

What are the best potatoes for gratin?

Yukon Gold and Russet potatoes are ideal due to their texture and ability to absorb cream without becoming mushy.

Can I make potato gratin ahead of time?

Yes, you can assemble it up to a day in advance and refrigerate it. Bake just before serving.

How thin should the potato slices be?

Aim for about 1/8 inch thick slices to ensure even cooking and a tender texture.

Can I freeze potato gratin?

It is not recommended as the cream may separate and the texture of the potatoes can become grainy after thawing.

What can I serve with potato gratin?

It pairs well with roast meats, grilled vegetables, salads, or as part of a holiday spread.

Can I use milk instead of cream?

Yes, but the dish will be less rich. Whole milk is the best substitute if you choose to go lighter.

How do I prevent the top from burning?

Cover the dish with foil for the majority of baking and uncover during the last 15–20 minutes.

Why is my gratin watery?

This can result from using potatoes with high water content or insufficiently thick cream. Using starchy potatoes helps absorb liquid.

Can I add breadcrumbs on top?

Yes, for a crispy topping, mix breadcrumbs with melted butter and sprinkle on top before the final baking stage.

How long should potato gratin rest before serving?

Allow it to rest for 10–15 minutes to set properly and make serving easier.
