A small amount of truffle oil infuses the whole dish with loads of earthy essence. If you don't have truffle oil, you can use olive oil for a more subtle flavor. Use a mandoline for quick, easy, uniform potato slices.
Decided to use the olive oil instead and it did give the dish a light flavor coupled with the fresh thyme. Potatoes inverted perfectly onto plate, no sticking and it held beautifully. I cooked on the stovetop as directed, but either during this process or while in the oven the potatoes browned too much. Maybe it only needed five minutes on the stovetop.
