# Steps:
01 - Preheat oven to 400°F.
02 - In a large skillet, heat olive oil and butter over medium heat. Add bacon and cook until starting to crisp, about 3 minutes.
03 - Add onion, leeks, carrots, and celery. Sauté for 5 to 6 minutes until softened.
04 - Stir in garlic and cook for 1 minute.
05 - Add chicken pieces and cook until lightly golden on all sides, about 5 minutes.
06 - Sprinkle flour over the mixture and stir well, cooking for 2 minutes.
07 - Gradually pour in chicken stock, stirring constantly to avoid lumps. Add milk and cream, and bring to a simmer.
08 - Stir in Dijon mustard, thyme, parsley, salt, and pepper. Simmer for 8 to 10 minutes, until sauce thickens and chicken is cooked through. Remove from heat and let cool slightly.
09 - Spoon filling into a deep 1.5 to 2 liter pie dish. Unroll puff pastry and lay it over the top, trimming any excess. Press edges to seal and cut a small slit in the center for steam to escape.
10 - Brush pastry with beaten egg. Bake for 30 to 35 minutes, until golden and puffed.
11 - Rest for 5 minutes before serving. Garnish with extra parsley if desired.
