Potato, Leek, Gruyere, and Oyster Mushroom Gratin

I had this served to me the other night and the amount of comments generated from this dish made me think I needed to get the recipe. I am so glad that I did!! This does make a lot, but it can be cut in half for a smaller setting

  1. Blue Plate Special
    Prepared 11/6/2008 Delicious side dish for a roast. #61718, but with revised cooking times per Chef #993408 Not sure why it says half the mushrooms as very few are that small. Substituted Jarlsberg for Gruyere as this was what I had on hand, and accidentally put in equal amounts of chicken broth and wine, but it was not overdone. Heated the liquids prior to adding to quicken cooking time.
