Flaky-crusted turkey pot pie filled with tender turkey, peas, and carrots in a creamy sauce is a wonderful way to use holiday leftovers. This high protein family dinner is cozy and satisfying.
Preheat your oven to 400°F (205°C) and set rack to the center position. Let the prepared pie crusts rest at room temperature during prep.
Melt butter in a large skillet over medium heat. Add diced onion, carrots, and celery; sauté for 5–6 minutes until softened and onions are translucent.
Sprinkle flour evenly over the vegetables, stirring constantly to form a roux; cook on medium for 2–3 minutes to remove raw flour taste.
Gradually whisk in chicken broth and milk, increase heat to medium-high, and cook until thickened, about 4–5 minutes, stirring frequently.
Add cooked turkey, peas, salt, pepper, and thyme into the thickened sauce; stir to combine and remove from heat.
Fit one pie crust into a 9-inch pie dish, easing it into the corners without stretching. Pour in the turkey filling and smooth the top.
Drape the second crust over the filling, trim excess, and crimp edges to seal. Cut several slits in the top crust for steam to escape.
Brush the top crust lightly with milk or beaten egg for color (optional).
Bake for 35–40 minutes until the crust is golden brown and the filling is bubbling. If edges brown too quickly, shield with foil.
Let the pie rest for 10 minutes before slicing to set the creamy filling.
