Ingredients

• 500 g Chicken breasts
• 2 large Leeks
• 30 g Butter
• 1 tbsp Olive oil
• 2 tbsp Plain flour
• 300 ml Chicken stock
• 1.5 tbsp Dijon mustard
• 1 tbsp Whole-grain mustard
• 100 ml Double cream
• 1 tsp Fresh thyme leaves
• 1 tsp Salt
• 0.5 tsp Ground black pepper
• 320 g Ready-made puff pastry
• 1 large Egg, beaten
• 1 tbsp Flour for dusting

Directions

Step 1

Preheat your oven to 200°C (400°F) or 180°C (350°F) for fan ovens.

Step 2

Slice the leeks into thin rounds and thoroughly rinse them to remove any grit.

Step 3

Cut the chicken breasts into bite-sized pieces.

Step 4

Heat the olive oil and butter in a large frying pan over medium heat until melted.

Step 5

Add the chicken and cook for 5-7 minutes, stirring occasionally, until golden. Remove and set aside.

Step 6

In the same pan, add the leeks and cook for 5 minutes until softened.

Step 7

Sprinkle the flour over the leeks and stir well to coat. Cook this mixture for 1 minute.

Step 8

Gradually pour in the chicken stock, stirring constantly, until the sauce is smooth and thickened.

Step 9

Stir in the Dijon mustard, whole-grain mustard, and double cream. Mix well.

Step 10

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.

Step 11

Lightly flour a clean work surface and roll out the puff pastry to fit the top of your pie dish.

Step 12

Transfer the chicken and leek filling into a pie dish and even it out with a spoon.

Step 13

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.

Step 14

Cut a small slit or poke a hole in the center of the pastry to let steam escape during baking.

Step 15

Brush the beaten egg over the pastry to give it a golden finish.

Step 16

Bake in the preheated oven for 30-35 minutes, or until the pastry is puffed and golden brown.

Step 17

Remove from the oven and allow the pie to rest for 5 minutes before serving.
