Chicken and Leek Pie with Shortcrust Pastry

Chicken and leek pie with shortcrust pastry is a savory British-style pie filled with tender chicken, soft leeks and a creamy, lightly seasoned sauce beneath a crisp pastry lid. Cooking the filling before assembling the pie keeps the pastry flaky and makes it easier to check that the chicken is safely cooked.

Ingredients

1 sheet ready-rolled shortcrust pastry, about 10 oz (280 g), thawed if frozen; or enough homemade pastry for a 9-inch (23 cm) pie dish
1 lb 5 oz (600 g) boneless, skinless chicken thighs or breasts, cut into ¾-inch (2 cm) pieces
2 medium leeks, about 12 oz (340 g) trimmed weight, cleaned and sliced
2 tablespoons (28 g) unsalted butter
1 tablespoon (15 ml) olive oil
⅓ cup (45 g) all-purpose flour
1¾ cups (420 ml) chicken broth, preferably low-sodium
½ cup (120 ml) whole milk
½ teaspoon fine salt, plus more to taste
¼ teaspoon black pepper
½ teaspoon dried thyme, or 1 teaspoon fresh thyme leaves
1 large egg, beaten with 1 tablespoon (15 ml) water, for brushing the pastry

Instructions

Prepare the oven and dish. Heat the oven to 400°F (200°C). Set a rack in the middle of the oven and place a baking sheet on it to heat. Keep the pastry chilled until needed. Trim the root and dark green tops from the leeks, halve them lengthwise, rinse between the layers to remove grit, then slice thinly.
Cook the chicken. Heat the oil in a large skillet over medium-high heat. Add the chicken in a single layer, working in batches if needed, and cook for 5–7 minutes, turning the pieces until browned and cooked through. Check the thickest pieces with a food thermometer: USDA FSIS gives poultry a safe minimum internal temperature of 165°F (74°C). Transfer the chicken to a clean plate.
Soften the leeks. Reduce the heat to medium and add the butter to the skillet. When melted, add the leeks and cook for 6–8 minutes, stirring often, until soft but not browned. If the pan becomes dry, add a tablespoon of water rather than letting the leeks catch.
Make the sauce. Sprinkle the flour over the leeks and stir for 1 minute. Gradually pour in the broth, stirring or whisking to avoid lumps, then add the milk, salt, pepper and thyme. Bring to a gentle simmer and cook for 3–5 minutes, stirring, until the sauce thickens enough to coat a spoon. Stir the cooked chicken and any juices on its plate back into the pan. Taste and adjust the seasoning.
Cool the filling briefly. Remove the skillet from the heat and let the filling cool for about 10 minutes. This short rest helps prevent the pastry from softening immediately on contact. If making the filling ahead, cool it promptly and refrigerate it; do not leave cooked chicken at room temperature for more than 2 hours.
Assemble the pie. Spoon the filling into a 9-inch (23 cm) pie dish and level it. Lay the pastry over the top, leaving a little overhang. Press the pastry onto the rim to seal, then trim the excess. Cut a small slit in the center for steam to escape. Brush the top with the beaten egg mixture, taking care not to block the vent.
Bake and rest. Set the dish on the hot baking sheet and bake for 25–30 minutes, until the pastry is deeply golden and crisp. If the top browns too quickly, loosely cover it with foil. Let the pie stand for 10 minutes before serving so the filling settles. The chicken was checked during cooking; if a temperature check is needed in the assembled pie, the center of the filling should reach 165°F (74°C).

Tips

Clean leeks thoroughly: grit hides between the layers. Halve and rinse them before slicing, or rinse the sliced pieces in a bowl and lift them out, leaving grit behind.
Keep pastry cold: warm pastry can become sticky and bake less crisp. If it softens while you assemble the pie, refrigerate it for 10–15 minutes before baking.
Thicken the filling before topping: it should be creamy, not watery. Simmer the sauce a little longer if it runs freely; a loose filling can make the bottom edge soggy.
Use chicken you have cooked safely: avoid crowding the pan, which makes the meat steam instead of brown. Cook in batches and check the largest pieces with a thermometer.

Serving Suggestions

Serve slices warm with peas, green beans or steamed broccoli to balance the rich pastry and creamy filling. For a more substantial plate, add mashed potatoes or roasted carrots. A simple dressed green salad is a lighter accompaniment, especially if the pie is served for lunch.

Variations

Replace up to half the chicken broth with milk for a softer, milkier sauce, or stir in ½ cup (60 g) sliced mushrooms with the leeks. For a more herby filling, use fresh parsley or tarragon in place of thyme. If ready-rolled shortcrust pastry is unavailable, puff pastry works as a top crust, though it will be lighter and more layered rather than crisp and crumbly. For a vegetarian version, omit the chicken and use 12 oz (340 g) mushrooms or cooked cannellini beans; use vegetable broth and cook the filling until hot throughout.

Storage and Reheating

Cool leftovers and refrigerate them within 2 hours of baking, covered, for 3–4 days. For best pastry texture, reheat portions in a 350°F (175°C) oven for about 20–25 minutes, covering loosely with foil if the crust is already dark; uncover for the last few minutes. Reheat until the center reaches 165°F (74°C), the safe temperature for leftovers. A microwave works for a quick portion, but the pastry will soften. Freeze the baked pie or individual portions, wrapped well, for up to 2 months for best quality; thaw overnight in the refrigerator and reheat to 165°F (74°C). Avoid reheating the same portion more than once.

Frequently Asked Questions

Can I make the filling ahead?
Yes. Cook the filling, cool it promptly, and refrigerate it in a covered container for up to 2 days. Assemble and bake when ready, allowing a few extra minutes if the filling is cold. The finished filling should be hot throughout.

Can I use leftover cooked chicken?
Yes. Use about 1 lb (450 g) cooked chicken, cut into bite-size pieces, and stir it into the thickened leek sauce. Heat the filling until steaming, then assemble and bake. If reheating leftovers, the center must reach 165°F (74°C).

Should I blind-bake the pastry?
Not for this top-crust pie. The pastry sits over a cooked filling and bakes on a preheated sheet, so blind-baking is unnecessary. If using pastry to line the bottom as well, blind-baking can help prevent a soggy base.

Can I make individual pies?
Yes. Divide the filling among oven-safe ramekins and cut pastry lids to fit, leaving room to seal. Bake at the same temperature, checking after 18–22 minutes; the pastry should be golden and the center of the filling should reach 165°F (74°C).

Can I freeze chicken and leek pie?
Yes. Freeze it baked or assembled but unbaked, tightly wrapped, for up to 2 months for best quality. Thaw an unbaked pie in the refrigerator before baking; a baked pie can be thawed overnight and reheated until its center reaches 165°F (74°C).
