Ingredients 1 ½ tablespoons all-purpose flour, plus more for rolling 2 sheets frozen puff pastry, thawed 1 tablespoon unsalted butter 1 cup whole milk Coarse salt and ground pepper Ground nutmeg 6 ounces thinly sliced deli ham 1 cup grated Gruyere cheese 1 large egg, lightly beaten Directions On a floured work surface, roll each sheet puff pastry to a 10-by-13-inch rectangle. Transfer to 2 parchment-lined baking sheets and refrigerate. In a small saucepan, melt butter over medium. Add flour; cook, stirring, until golden, 1 minute. Whisking constantly, add milk and simmer. Stir until thickened, 5 minutes. Season with salt, pepper, and pinch of nutmeg. Pour sauce into a bowl and let cool 30 minutes. Preheat oven to 400 degrees, with rack in lower third. Arrange ham evenly on 1 pastry sheet, leaving a 3/4-inch border; top with cheese and sauce. Brush pastry border with egg; top with second pastry sheet. Fold bottom edges over top and press to seal.
