Like the asparagus tart that’s a harbinger of spring (see page 69), this mushroom-topped variation is a crowd-pleaser. It makes a lovely dinner, or, when cut into bite-size pieces, a perfect hors d’oeuvre for a cocktail party.

　　

Ingredients

serves 4

　　Flour for rolling out puff pastry

　　1 sheet frozen puff pastry (from a 17.3-ounce package), thawed according to package instructions

　　1 medium onion, halved and thinly sliced

　　2 tablespoons olive oil

　　Coarse salt and fresh ground pepper

　　2 packages (10 ounces each) white mushrooms, trimmed and thinly sliced

　　1 package (10 ounces) fresh baby spinach

　　2 ounces soft goat cheese, crumbled

　　

Step 1

Preheat the oven to 400°F. On a floured surface, roll the puff pastry out to a 16-by-10-inch rectangle. Trim uneven edges. Place the pastry on a baking sheet. With a sharp knife, lightly score the dough to form a 1-inch border. Using a fork, prick the dough inside the border every 1/2 inch. Bake until golden, rotating the pan once, about 15 minutes.

　　

Step 2

Meanwhile, in a small saucepan with a tight-fitting lid, toss the onion with 1 tablespoon of the oil. Season with salt. Cover and cook over medium heat until the onion begins to brown, about 5 minutes. Stir. Continue cooking with the cover on for 15 minutes, stirring every 5 minutes. Set aside.

　　

Step 3

In a large saucepan with a tight-fitting lid, heat the remaining tablespoon of oil. Add the mushrooms; cover and cook until tender and all liquid has evaporated, about 10 minutes. Fold in the spinach; season with salt and pepper. Cover and cook until wilted, about 5 minutes more. Drain any liquid.

　　

Step 4

Top the dough with the mushroom-spinach mixture. Scatter the onions and goat cheese on top. Bake until the cheese is lightly browned, about 15 minutes.
