A few shiitake mushrooms added to the cremini or button mushrooms can really dial up the mushroom flavor in this mushroom pie, so if you have them, use them! If not, no worries, the mushroom pie will still be wonderful without them.
Ingredients
1 basic pie dough recipe, rolled out and lining a 9 or 10-inch pie dish, or 8x8 baking dish, frozen for at least 30 minutes (or one deep-dish frozen pie crust)
2 Tbsp butter
1 lb cremini or button mushrooms, sliced 1/4-inch thick
4 to 5 shiitake mushrooms, caps only, sliced (optional)
1 clove garlic, minced (about 1 teaspoon)
Salt and pepper
1/4 cup cream
1/2 cup milk
1/3 cup sour cream
2 eggs, lightly beaten
A dash of ground cardamom or nutmeg (optional)
1 Tbsp chopped fresh parsley
1 cup (4 ounces) grated Monterey Jack cheese
Sounds good.
