3 varieties of mushrooms (shiitake, oyster, and chanterelle) are needed for this recipe.

Preparing the pie filling.

Before the bake.


FILLING                                                   CRUST

2 ½ cups chopped onions                          2 ½ cups unbleached white flour

3 tbsps butter                                                2 tsps baking powder

8 cups chopped mushrooms                     ¼ tsp salt

1 tsp dried thyme                                         1 cup butter

½ tsp salt                                                       1 cup sour cream

Lots of freshly ground black pepper        Flour for coating the dough and board for rolling

8 oz. cream cheese


1 egg

1 tbsp milk

To make the filling, sauté the onions in the butter in a large skillet. When onions are soft and translucent, add mushrooms and thyme and sauté for a few more minutes, until the mushrooms release their juices. Add the seasonings. Cut the cream cheese into small pieces and then stir it into the mushrooms until it melts. Remove from the heat and set aside until the crust is ready.

Preheat the oven to 400°.

For the crust, combine the flour, baking powder, and salt in a large mixing bowl. Using an electric mixer or by hand, cut in the butter just enough to achieve an evenly textured crumbly mix. Stir in the sour cream to form a soft dough. Generously dust the dough with flour and form it into a ball.

On a heavily floured board, roll out 2/3 of the dough to fit a 10-inch pie plate. Trim the edges. Fill with the mushroom mixture. Roll out the remaining dough about ¼ inch thick (thicker than a usual pie crust) and cut into strips 1 inch wide. Weave the strips into a lattice over the filling. Fold the ends of the lattice strips under the bottom crust, pinch the edges together, and flute.

For the glaze, beat the egg and milk. With a pastry brush, thoroughly coat the pie crust.

Bake the pie for 25 to 35 minutes, until the crust is puffy and golden.

Serve with glazed onions, and beet and horseradish salad.
