Instructions

In a large skillet, heat 1 tablespoon butter over medium-high heat. Add half of the mushrooms and leek. Cook and stir until mushrooms are lightly browned and leek is tender; remove from pan. Repeat with remaining butter, mushrooms and leek, adding garlic during the last minute of cooking. Return all to pan.
Stir in wine and cream; cook 1-2 minutes or until liquid is almost evaporated. Stir in herbs, salt and pepper. Remove from pan; cool completely.
Preheat oven to 375°. Place one sheet of phyllo dough on a work surface; brush with butter. Layer with five additional phyllo sheets, brushing each layer. (Keep remaining phyllo covered with plastic wrap and a damp towel to prevent it from drying out.)
Spoon half of the mushroom mixture down center third of phyllo dough to within 1 in. of ends. Sprinkle filling with 2 tablespoons cheese. Fold up short sides to enclose filling. Roll up jelly-roll style, starting with a long side.
Transfer to a parchment paper-lined 15x10x1-in. baking pan, seam side down. Brush with additional butter. Repeat with remaining ingredients. Bake 18-22 minutes or until golden brown.
Let stand 10 minutes before slicing. Serve warm.
