Before You Begin
Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
Fit the bottom pie crust into a 9-inch pie dish.
Melt 2 tablespoons butter in a skillet over medium heat. Add onion, carrots, and celery. Cook 5–7 minutes until softened.
Stir in cooked chicken, peas, thyme, salt, and pepper. Remove from heat.
In a saucepan, melt 3 tablespoons butter over medium heat. Whisk in flour and cook 1–2 minutes until smooth.
Slowly whisk in chicken broth and simmer until thickened. Remove from heat and stir in cream.
Combine sauce with chicken mixture and stir gently.
Transfer filling to pie crust. Top with second crust, seal edges, and cut small vents.
Bake 30–40 minutes until crust is golden and filling reaches 165°F (74°C) internally and bubbles at edges.
Rest 10–15 minutes before slicing so filling sets.
