There are quite a few potato gratin dishes we enjoy in Japan, but this was the first time I tried cooking it with leeks. Have you cooked with them before? Leeks are like giant green onions, but with a milder flavor. The slightly sweet yet savory and distinct herbaceous aroma is absolutely wonderful when paired with a cheesy potato gratin dish. My family absolutely loves this Potato Leek Gratin. With a deep golden brown top, it’s nearly impossible not to go back for a second bite.
