Mushroom And Spinach Quiche In A Potato Crust

Preheat oven to 400 F.

Lightly grease a 9-inch glass or ceramic pie dish with 1/4 teaspoon oil. Toss potatoes with 1 teaspoon oil and 1/8 teaspoon each salt and pepper. Press into an even layer in pie dish, creating a crust. Bake until golden brown at the edges and dry, about 20 minutes. Let cool.

Lower the oven to 325°. Heat 1 teaspoon oil in a large skillet, preferably non-stick, over medium heat. Add onion and cook until softened and golden, about 5 minutes. Add remaining teaspoon oil and mushrooms and cook, stirring, until mushrooms release their liquid and most of the liquid evaporates, about 8 minutes. Add spinach and 1/4 teaspoon each salt and pepper, and cook, stirring, just until spinach wilts, about 30 seconds. Let cool slightly.

Whisk together eggs, milk, and remaining 1/8 teaspoon salt and pepper. Spread the mushroom mixture in an even layer in the pie dish, and top with an even layer of the cheese. Carefully pour in egg mixture. Bake until firm around the edges, but still wobbly in the center, about 20 minutes. Let cool, and serve warm or at room temperature.
