Ingredients

  • 6 tablespoons butter

  • 1 ½ pounds fresh mushrooms, quartered

  • 1 ½ pounds fresh shiitake mushrooms, stemmed and coarsely chopped

  • 3 tablespoons minced garlic

  • 2 teaspoons dried thyme

  • 1 teaspoon dried rosemary, crushed

  • salt to taste

  • ground black pepper to taste

  • 2 cups chicken broth

  • 3 pounds Yukon Gold potatoes, peeled and cut into 1/8 inch thick slices

  • 2 cups Parmesan cheese

  • 2 cups heavy cream

  • 1 ¼ teaspoons salt

  • 1 teaspoon ground black pepper

  • 2 cups half-and-half cream

Directions

  1. Melt butter in a large pot over high heat. Saute mushrooms in butter until liquid evaporates, about 10 minutes. Stir in garlic, thyme, and rosemary, and cook for 1 minute. Pour in chicken broth, and simmer until liquid evaporates. Season with salt and pepper. Set aside.

  2. Preheat to 375 degrees F (190 degrees C). Butter a 13x9x2 inch baking dish.

  3. Arrange 1/3 of the potatoes in prepared dish, overlapping slightly. Spread half of the mushroom mixture evenly over the potatoes, and then sprinkle 1/3 of the cheese over mushrooms. Repeat layering, and then arrange remaining potatoes on top.

  4. In a large bowl, mix together the half and half, heavy cream, 1 1/4 teaspoon salt, and 1 teaspoon pepper. Pour mixture over potatoes. Cover loosely with foil.

  5. Place baking dish on middle rack in oven. Bake until potatoes are tender, about 1 hour and 15 minutes. Uncover. Sprinkle remaining cheese over potatoes. Bake until cheese melts, about 15 minutes longer.
