Preheat your oven to 200°C (400°F) or 180°C (350°F) for fan ovens.
Slice the leeks into thin rounds and thoroughly rinse them to remove any grit.
Cut the chicken breasts into bite-sized pieces.
Heat the olive oil and butter in a large frying pan over medium heat until melted.
Add the chicken and cook for 5-7 minutes, stirring occasionally, until golden. Remove and set aside.
In the same pan, add the leeks and cook for 5 minutes until softened.
Sprinkle the flour over the leeks and stir well to coat. Cook this mixture for 1 minute.
Gradually pour in the chicken stock, stirring constantly, until the sauce is smooth and thickened.
Stir in the Dijon mustard, whole-grain mustard, and double cream. Mix well.
Add the cooked chicken back into the sauce, along with the thyme leaves, salt, and black pepper. Simmer for 2-3 minutes, then remove from the heat and allow to cool slightly.
Lightly flour a clean work surface and roll out the puff pastry to fit the top of your pie dish.
Transfer the chicken and leek filling into a pie dish and even it out with a spoon.
Cover the filling with the puff pastry, trimming any excess. Press the edges down to seal, and crimp them with a fork if you wish.
Cut a small slit or poke a hole in the center of the pastry to let steam escape during baking.
Brush the beaten egg over the pastry to give it a golden finish.
Bake in the preheated oven for 30-35 minutes, or until the pastry is puffed and golden brown.
Remove from the oven and allow the pie to rest for 5 minutes before serving.
