# How-To Steps:
01 - Set oven temperature to 400°F.
02 - Heat olive oil in a large skillet over medium heat. Add diced onion, sliced carrots, and celery; cook for 6 to 8 minutes until softened.
03 - Stir in minced garlic and cook for 1 minute. Add chicken pieces, salt, and black pepper; cook until chicken is lightly browned, about 5 minutes.
04 - Sprinkle all-purpose flour over mixture and stir to coat. Cook for 2 minutes to remove raw flour taste.
05 - Gradually add chicken broth and milk while stirring constantly. Add bay leaves, thyme, and rosemary. Bring to a simmer and cook for 8 to 10 minutes until thickened. Remove from heat, stir in peas and parsley, then discard bay leaves.
06 - Transfer filling into a 9-inch deep-dish pie pan or ovenproof skillet. Allow to cool slightly.
07 - Combine flour and salt in a large bowl. Add cold butter cubes and cut in with a pastry cutter or fingers until coarse crumbs form. Add ice water gradually, mixing with a fork until dough just holds together. Shape dough into a disk, wrap, and refrigerate for 20 minutes.
08 - On a floured surface, roll dough into a circle slightly larger than the pie dish. Place crust over filling, trim excess, and crimp edges to seal. Cut small slits in crust to vent steam.
09 - Beat egg with 1 tablespoon water and brush evenly over crust surface.
10 - Bake for 35 to 40 minutes until crust is golden brown. Let rest for 10 minutes before serving.
