In this recipe we call for a 10 1/2- by 7 1/2- by 1-inch rectangular tart pan. The tart could also be made using a baking sheet or a jelly-roll pan, as the filling is dense enough to hold its shape on its own.
03Stack phyllo sheets and cover with 2 overlapping sheets plastic wrap and then a dampened kitchen towel. In a small saucepan melt butter and cool slightly. Lightly brush a 10 1/2- by 7 1/2- by 1-inch rectangular tart pan with a removable fluted rim with butter.
04On a work surface lightly brush 1 phyllo sheet with butter. Sprinkle 1 tablespoon Parmesan evenly over buttered phyllo and repeat layering with 5 more phyllo sheets, butter, and 5 tablespoons Parmesan. Arrange last phyllo sheet on stack and lightly brush with butter. Transfer phyllo to tart pan, letting excess hang over edge, and spoon filling onto phyllo, spreading evenly. Fold edges of pastry over filling, leaving center uncovered , and lightly brush top of phyllo with butter. Sprinkle remaining 1/4 cup Parmesan over exposed filling and bake tart in middle of oven until golden, 25 to 30 minutes. Serve tart warm or at room temperature.
