FLAKY CHICKEN HAND PIES

Steps:

• Heat oven to 375 degrees. Season chicken generously with salt and pepper. Roast, uncovered, for 45 minutes to 1 hour, until cooked through. Set aside until cool enough to handle.
• Remove skin and meat from bones. Chop meat roughly into 1/2-inch chunks and set aside or refrigerate, covered, for up to 2 days. (If desired, save skin, bones and pan drippings for stock.)
• Make filling: In a large skillet, melt butter over medium-high heat. Add onion and cook until softened, stirring, about 5 minutes. Add garlic, thyme and chopped mushrooms. Season mixture with salt and pepper and reduce heat to medium.
• Cook, stirring, until onions have colored slightly and mushrooms are tender, about 5 minutes. Sprinkle with flour and stir to coat. Add broth and cook, stirring, as mixture thickens. Add chicken, turn heat to low and cook 5 minutes more. Stir in crème fraîche, turn off heat, and set aside to cool. Stir in scallions and parsley. Season with salt and pepper to taste.
• Line 2 baking sheets with parchment paper. Unfold puff pastry on a lightly floured (or parchment-paper-covered) work surface. Using a rolling pin, roll out into an approximate 15-inch square. Use the tip of a knife to cut into 9 equal squares. Spoon about 3/4 cup chicken mixture into the center of each piece, then divide any remaining mixture evenly on top, so each has the same amount.
• Pick up and fold one corner of pastry over the filling to make a triangular pie. Press and pinch both edges together tightly to seal. Divide on the prepared pans.
• Brush the tops with egg wash and bake until deep golden brown, about 20 to 25 minutes. Serve warm.
