10 - 1 2/3 cups whole milk

# Method:
01 - Preheat oven to 400°F (180°C convection). Arrange all ingredients and equipment within reach for efficient preparation.
02 - In a large frying pan over medium heat, cook bacon until golden and crisp, approximately 5-7 minutes. Remove with slotted spoon and set aside on paper towels.
03 - In the same pan, add chicken pieces in a single layer. Brown on all sides for 5-6 minutes until light golden. Transfer to a plate.
04 - Add butter to the pan, then stir in chopped onion, leeks, carrots, and celery. Sauté for 8-10 minutes until softened. Add minced garlic and cook for 1 minute additional.
05 - Sprinkle flour over the vegetables, stirring constantly for 1 minute to cook out the raw flour taste and create a roux foundation.
06 - Gradually pour in milk and chicken stock while stirring constantly to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until sauce reaches desired thickness.
07 - Stir in cooked bacon, seared chicken, heavy cream, Dijon mustard, and thyme. Season thoroughly with salt and pepper to taste. Remove from heat and allow to cool for 10 minutes.
08 - Pour the cooled filling into a 1.6 quart pie dish, ensuring even distribution.
09 - Unroll pastry sheet and lay it over the filling. Trim excess pastry around edges and press firmly to seal. Cut 2-3 small slits in the top surface to allow steam to escape. Brush entire surface with beaten egg.
10 - Bake for 30-35 minutes until pastry is golden brown and crisp. Allow pie to rest for 5 minutes before serving.
