Chicken and Leek Pie Video: A Flaky, Creamy Recipe

Chicken and leek pie is a comforting British-style savory pie filled with tender chicken, sweet leeks and a creamy sauce beneath crisp puff pastry. This version cooks the filling on the stovetop, then bakes it under pastry until golden; the video-friendly steps make it easy to follow, and you can use cooked chicken to save time.

Ingredients

1½ lb (680 g) boneless, skinless chicken thighs, cut into 1-inch (2.5 cm) pieces
1 tsp (5 ml) fine salt, divided
½ tsp (2.5 ml) black pepper, divided
2 tbsp (30 ml) olive oil
2 tbsp (28 g) unsalted butter
2 large leeks, about 1 lb (450 g) before trimming, white and light green parts only, cleaned and sliced
1 medium carrot, about ¾ cup (90 g), peeled and diced
2 garlic cloves, minced
⅓ cup (40 g) all-purpose flour
1½ cups (360 ml) low-sodium chicken broth
¾ cup (180 ml) whole milk
½ tsp (2.5 ml) dried thyme, or 1 tsp (5 ml) fresh thyme leaves
½ cup (70 g) frozen peas
1 sheet (about 10 oz / 280 g) all-butter puff pastry, thawed according to package directions but kept cold
1 large egg (about 50 g), beaten with 1 tsp (5 ml) water, for brushing

Instructions

Heat the oven to 400°F (200°C). Set a rack in the middle. Pat the chicken dry and season it with half the salt and pepper. Cut the leeks lengthwise, rinse between the layers to remove grit, then slice them. Keep the pastry refrigerated while you prepare the filling.
Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the chicken in a single layer, working in batches if needed, and brown for about 4 minutes, turning once. It does not need to be fully cooked yet. Transfer it to a clean plate; avoid reusing a plate that held raw chicken unless it has been washed.
Reduce the heat to medium. Add the butter, leeks and carrot. Cook for 7–9 minutes, stirring often, until the leeks are soft but not browned. Stir in the garlic and thyme for 30 seconds.
Sprinkle the flour over the vegetables and stir for 1 minute so it coats them evenly. Gradually pour in the broth, stirring and scraping the pan, then add the milk and remaining salt and pepper. Bring the sauce to a gentle simmer and cook for 3–4 minutes, stirring, until it thickens enough to coat a spoon.
Return the chicken and any juices to the pan. Simmer gently for 5–8 minutes, stirring occasionally, until the thickest chicken pieces reach 165°F (74°C) on a food thermometer; this is the USDA FSIS safe minimum internal temperature for poultry. Stir in the frozen peas, then take the pan off the heat. Taste the filling and adjust the seasoning. If it looks loose, simmer it briefly before assembling; a thin filling can make the pastry soggy.
Pour the filling into a 9-inch (23 cm) deep pie dish, spreading it evenly. Let it cool for 10 minutes so the pastry is less likely to soften on contact. Lay the cold puff pastry over the top. Trim any excess, leaving about ½ inch (1.3 cm) overhang, then tuck or press the edge against the rim. Cut two or three small slits in the center to release steam.
Brush the pastry with beaten egg, taking care not to let egg run down the sides, which can glue the pastry to the dish. Place the pie on a baking sheet to catch any bubbling sauce. Bake for 25–30 minutes, until the pastry is puffed and a deep golden brown. If the top browns too quickly, loosely cover it with foil for the remaining bake.
Rest the pie for 10 minutes before serving. The filling will be very hot, and resting helps it settle so portions hold together.

Tips

Clean leeks thoroughly: Soil often hides between the layers. Slice them first, then swish in a bowl of cold water and lift them out, leaving grit behind.
Keep puff pastry cold: If it becomes soft and sticky while you assemble the pie, chill it for 10–15 minutes. Cold pastry puffs more reliably in the oven.
Use cooked chicken if convenient: Add about 3 cups (400 g) shredded cooked chicken after the sauce has thickened, then heat it through. Check that the filling reaches 165°F (74°C) before baking.
Choose the right dish: A deep 9-inch pie dish gives the filling room. A shallow dish may leave extra filling; bake any excess separately in a small oven-safe dish rather than overfilling.

Serving Suggestions

Serve the pie warm, allowing one generous wedge per person. A crisp green salad with a simple vinaigrette balances the rich sauce, while steamed green beans, broccoli or peas make an easy side. For a more substantial meal, add mashed potatoes or roasted root vegetables, though the pastry already provides a satisfying starch.

Variations

Chicken breast: Substitute boneless, skinless chicken breast for the thighs. It is leaner, so avoid overcooking it on the stovetop and rely on a thermometer to reach 165°F (74°C).
Mushroom and leek: Replace the carrot with 8 oz (225 g) sliced mushrooms. Cook them with the leeks until their released liquid has mostly evaporated before adding flour.
Herb change: Use 1 tbsp (4 g) chopped fresh parsley in place of the thyme, stirring it in with the peas. Parsley gives a fresher, milder flavor.
Individual pies: Divide the filling among six oven-safe ramekins and top each with pastry. Bake on a sheet at the same temperature, checking after 18–22 minutes for puffed, golden pastry.
Pastry alternatives: Shortcrust pastry makes a firmer, less flaky lid; follow its package directions for baking. For a dairy-free version, use plant-based butter and unsweetened, unflavored plant milk, and check that the pastry is dairy-free; the sauce may be slightly less rich.

Storage and Reheating

Refrigerate leftovers within 2 hours of baking, covered or in an airtight container. They keep for 3–4 days in the refrigerator. To freeze, cool the pie promptly, wrap it well, and freeze for up to 2 months for best quality; thaw overnight in the refrigerator before reheating. For the crispest pastry, reheat portions in an oven at 350°F (175°C) until the center reaches 165°F (74°C) on a food thermometer, usually 20–30 minutes from chilled, depending on portion size. Cover loosely with foil if the pastry is browning too much. Microwave reheating is quicker but softens the crust; heat until the center reaches 165°F (74°C).

Frequently Asked Questions

Can I make chicken and leek pie ahead?
Yes. Prepare the filling up to 2 days ahead, cool it, and refrigerate it promptly. Assemble with cold pastry shortly before baking. If the filling is cold, the pie may need a few extra minutes in the oven; check that it is piping hot throughout and the chicken has reached 165°F (74°C).

Can I use leftover roast chicken?
Yes. Use about 3 cups (400 g) cooked, shredded chicken. Make the sauce and vegetables first, stir in the chicken, and heat the filling to 165°F (74°C) before topping and baking. This is also a good way to use refrigerated leftovers within their safe storage window.

Why is my pie filling runny?
The sauce may not have simmered long enough to thicken, or the filling may have gone into the dish too hot and loose. Simmer it until it coats a spoon before assembling, and allow it to cool briefly. Avoid cutting the pie immediately after baking; the 10-minute rest helps the sauce settle.

Can I make this without puff pastry?
Yes. Use shortcrust pastry or a pastry lid made from a suitable ready-made dough, following the package’s baking guidance. You can also serve the creamy chicken and leek filling without a crust, with potatoes or bread, but it will no longer have the crisp pie topping.

Do I need to blind-bake the pastry?
No. This recipe uses pastry only as a top crust, not as a base, so blind-baking is unnecessary. Keep it cold, cut steam vents and bake until well browned to help it puff and stay crisp.

Can I assemble the pie and freeze it unbaked?
For the best pastry texture, freeze the cooled filling separately and add fresh, thawed pastry after defrosting. If freezing an assembled pie, freeze it promptly and safely wrapped, thaw it in the refrigerator, then bake until the filling is hot throughout and reaches 165°F (74°C). Do not thaw it on the counter.
