Ingredients

Number of serving: 5
2 tablespoons. butter, divided

8 ounces. crimini mushrooms, cleaned and sliced - 1/4-inch thick

2 garlic cloves, minced

2 cups thinly sliced leeks, white and pale green parts

leaves from 2 sprigs fresh thyme, minced (about 1 teaspoon.)

3/4 cup chicken broth

1 cup cream

3 tablespoons. dry white wine

1/2 teaspoon. kosher salt

1/4 teaspoon. black pepper

1 1/2 pounds russet potatoes, peeled and thinly sliced

1 cup grated Swiss cheese

1/4 cup freshly grated parmesan cheese

1 tablespoons. plain breadcrumbs

Preparation

  • Melt 1 tablespoon. butter in a saute pan over medium-high heat. Add mushrooms and saute until almost tender, about 5 minutes.
  • Add garlic and saute until mushrooms are tender and golden and their liquid has evaporated. Transfer mushroom mixture to a bowl.
  • In the same pan, melt 1 tablespoon. butter. Add the leeks and thyme. Saute until leeks are tender and starting to brown, about 8 minutes. Transfer to the bowl with the mushrooms and stir to combine.
  • Preheat oven to 400F. Butter a baking dish (about 9-inch square). Whisk broth, cream, wine, salt and pepper in a bowl to blend. Arrange 1/3 of potatoes in the bottom of the dish. Top with 1/2 the mushroom leek mixture and 1/2 the Swiss cheese.
  • Create another layer of potatoes on top, then pour half the cream mixture over it. Add the remaining leek and mushroom mixture, then the remaining Swiss cheese.
  • Top with the rest of the potatoes and then push the whole thing down with the back of a spatula. Pour the rest of the cream mixture over the top, then sprinkle with the Parmesan cheese and breadcrumbs.
  • Bake uncovered until potatoes are tender and sauce is bubbling thickly, about 1 hour 20 minutes. Let stand a few minutes before serving.
