Give me almost any combination of toppings, and I’ll turn them into a delicious savory tart. The formula is always the same: the crispy, buttery puff pastry crust; a creamy base of ricotta and crème fraîche; a layer of oozing, usually pungent cheese; and then, of course, the topping. In this case, I sauté an array of winter wild mushrooms until they’re tender, chewy, and still a little crisp. Since they seem to make everything taste better, I can’t resist tossing in a few handfuls of sweet young onions with their spicy green tops. As they all bake together, their flavors unite into this decadent and sophisticated “pizza.”

Cooks' Note

Assemble the tart in the morning, cover, and refrigerate. Bake just before you’re ready to serve.
