Creating a perfect chicken pot pie is as easy as following these simple steps:

1. Preheat the Oven
   Preheat your oven to 425°F (220°C) to ensure it’s hot and ready for baking.
2. Prepare the Roux
   In a saucepan, melt the butter over medium heat. Stir in the flour to create a roux, cooking for about 1-2 minutes until it’s slightly golden and fragrant.
3. Create the Sauce
   Gradually add the chicken broth and milk to the roux, stirring constantly until the mixture thickens to a creamy consistency.
4. Combine Ingredients
   Mix in the shredded chicken, mixed vegetables, onion powder, garlic powder, thyme, salt, and pepper. Stir well to ensure the ingredients are evenly distributed.
5. Assemble the Pie
   Pour the chicken and vegetable mixture into a pie crust placed in a pie dish.
6. Top with Second Pie Crust
   Cover the filling with a second pie crust. Seal the edges by pressing them together with a fork or your fingers. Cut small slits on the top crust to allow steam to escape during baking.
7. Bake
   Place the assembled pie in the preheated oven and bake for 25-30 minutes, or until the crust is golden brown.
8. Cool and Serve
   Allow the pie to cool slightly before serving. This helps the filling set and makes it easier to slice.
