For an even richer flavor, try using a combination of Gruyere and Emmental cheese. A mandoline can be used to achieve uniformly thin potato slices, ensuring even cooking. If the top of the gratin begins to brown too quickly, cover it loosely with foil during the final baking stage. Fresh thyme or rosemary sprigs can be added to the cream for an herbaceous infusion. The gratin can be assembled ahead of time and refrigerated for up to 24 hours before baking. Add an extra 15-20 minutes to the baking time if starting with a cold gratin.

Aug 15, 2024I found the wine flavor a bit strong, so next time, I'll use half wine and half chicken broth.

Aug 10, 2024I used Emmental cheese because I couldn't find Gruyère, and it was still delicious!

May 6, 2024This is a great make-ahead dish. I assembled it the day before and baked it the day of. It was a lifesaver!

May 2, 2024My gratin didn't get as brown on top as I would have liked. I think I'll try broiling it for a minute or two at the end next time.

Apr 23, 2024The potatoes were perfectly tender, and the Gruyère was so flavorful. I used a mandoline, which made slicing the potatoes so much easier.
