Ingredients
- 2 lb boneless skinless chicken breasts
- 3 cups chicken stock
- 5 tbsp unsalted butter
- 1 medium onion, diced
- 2 carrots, diced
- 2 celery stalks, sliced
- ⅓ cup all-purpose flour
- ¾ cup whole milk
- 1 cup frozen peas
- 1 tsp fresh thyme leaves
- 2 refrigerated pie crusts
- 1 large egg, beaten
- Salt and pepper to taste
Method
- Poach the chicken in the stock at a gentle simmer until it reaches 165°F, about 15 minutes. Save the stock and cut the chicken into bite-size pieces.
- Heat the oven to 400°F. Melt the butter in a large skillet and cook the onion, carrots and celery until tender, about 8 minutes.
- Stir in the flour for 1 minute, then whisk in 2 cups of the saved stock and the milk. Simmer until thick, about 3 minutes.
- Fold in the chicken, peas and thyme and season well with salt and pepper.
- Line a deep 9-inch pie dish with one crust, add the filling and lay the second crust on top. Crimp the edges, brush with egg and cut a few vents.
- Bake on a sheet pan until the crust is deep golden and the filling bubbles, 35 to 40 minutes. Rest 15 minutes before serving.
Notes
The filling can be made a day ahead; chill it completely before topping so the crust stays flaky.
For a crowd, bake the filling in a 9x13-inch dish under a single sheet of rolled-out crust.
