Make the filling
- Line a pie dish with one puff pastry sheet, pressing it into the dish edges so it holds shape. Set aside while you cook the filling.
- Sauté the butter, yellow onion, and carrots in a cast iron skillet over medium heat until the vegetables soften, about 5 minutes. Stir occasionally so nothing browns too fast.
- Whisk in the flour and cook for 1 minute to remove the raw taste. Keep stirring until the mixture looks slightly paste-like.
- Whisk in the chicken broth and then whisk in the cream until smooth, simmering just until thickened, 3 to 5 minutes. The sauce should coat the back of a spoon.
- Stir in the shredded chicken and frozen peas, heating through until hot, about 2 minutes. Turn off the heat and let the filling cool before assembling.
Assemble and bake
- Spoon the cooled chicken filling into the pastry-lined pie dish and spread it into an even layer. Leave a small border so the top crust can seal.
- Top with the second puff pastry sheet, trimming any overhang if needed. Press the edges to seal firmly.
- Brush the top pastry with the beaten egg to help it brown. Aim for full coverage for a deep golden color.
- Bake at 400°F for 35 minutes, until the crust is puffed and deeply golden. Let it rest for 5 minutes before slicing so the filling sets.
Notes
Pro tip: cool the filling to warm-room temperature before adding it—this keeps the puff pastry layers flaky instead of steaming into softness. Refrigerate leftovers in an airtight container for up to 3 days; reheat in a 350°F oven until hot and crisp. Freezing is not recommended because the puff pastry crust texture can soften after thawing. For a dietary swap, use unsalted butter and replace the cream with lactose-free cream for a similar silky filling.
