I served this for Christmas with a roasted beef tenderloin. It was absolutely fantastic! The seasonings were wonderful and the recipe was very easy to make. The only thing I changed was that I did not use any breadcrumbs. Instead, I used some fine grain bulgur for meatballs in the body of the dish and garnished with chopped green onions. Also, after I made it something told be to look again at the cheese package, and sure enough, I used the wrong cheese. I used Monterrey Jack by mistake. So, the recipe is versatile as well! I used only shiitake mushrooms. Will definitely be making this again! Thanks for posting.

  1. Preheat the oven to 400 degrees with the rack in the upper half of the oven.
  2. Thinly slice the potatoes about 1/8 inch on a mandolin, food processor, or the old fashioned way, a sharp knife .
  3. Melt the butter in a large sauté pan over high heat and add the shallots and sliced mushrooms and cook for about 6 to 8 minutes.
  4. Add the re-hydrated porcinis to the pan (if using) and sauté until the liquid from the mushrooms has evaporated.
  5. Season the mushrooms with salt and pepper.
  6. Add the chicken stock, 1 1/4 cup of the cream, and chopped herbs, heat through, do not boil.
  7. Use an oiled 3-quart baking dish.
  8. Begin with a layer of about 1/3 of the potatoes, 1/2 of the mushrooms and cream and a little of each cheese, 1/3 of the potatoes, the remaining 1/2 of the mushrooms with cream, then the final layer of potatoes.
  9. Pour the remaining 1/2 cup cream over the potato layers and top with the remainder of the cheeses.
  10. Cover with foil.
