2 large sweet onions, thinly sliced (about 2 pounds)
1 tablespoon butter or margarine, melted
1/4 teaspoon salt
1/4 teaspoon freshly ground pepper
1/2 (15-ounce) package refrigerated piecrusts
2 firm Bosc pears, peeled and thinly sliced
1 tablespoon all-purpose flour
1/2 cup coarsely chopped pecans
3 ounces crumbled Roquefort cheese
1 large egg, lightly beaten
How to Make It
Cook onion in butter in a large skillet over medium-low heat, 30 to 35 minutes or until onion is caramelized, stirring often. Stir in salt and pepper; set aside.
Unfold piecrust and roll into a 14" circle on a lightly floured surface. Transfer to a parchment paper-lined baking sheet.
Combine pear slices and flour; toss gently to coat.
Spread three-fourths of onion over piecrust, leaving a 4" border around edges. Arrange pear slices over onion; top with remaining onion, pecans, and cheese. Fold over 4" borders of dough, pressing gently to seal. Brush dough with beaten egg.
Bake at 425° for 24 to 25 minutes or until golden, shielding with aluminum foil, if necessary, to prevent excessive browning. Cool on baking sheet on a wire rack 5 minutes. Serve warm, or cool to room temperature on wire rack.
