Coles Kitchen Chicken and Leek Pie Recipe

Chicken and leek pie is a comforting savory pie with tender chicken and sweet, softened leeks in a creamy sauce beneath crisp puff pastry. This home-style version is inspired by the familiar Coles Kitchen combination, with straightforward ingredients and clear steps for a golden, well-set pie.

Ingredients

1.1 lb (500 g) boneless, skinless chicken thighs, cut into ¾-inch (2 cm) pieces
2 medium leeks, about 1 lb (450 g) before trimming, white and light-green parts only, washed well and sliced
2 tablespoons (28 g) unsalted butter
1 tablespoon (15 ml) olive oil
2 medium carrots, about 1 cup (130 g), peeled and diced
2 tablespoons (16 g) all-purpose flour
1 cup (240 ml) low-sodium chicken broth
½ cup (120 ml) heavy cream
1 teaspoon (5 ml) Dijon mustard
1 teaspoon fresh thyme leaves, or ½ teaspoon dried thyme
½ teaspoon fine salt, plus more to taste
¼ teaspoon black pepper
1 sheet frozen puff pastry, about 10 oz (280 g), thawed according to its package directions
1 large egg (about 50 g), beaten with 1 teaspoon (5 ml) water, for the pastry wash

Instructions

Thaw and prepare: If needed, thaw the puff pastry in the refrigerator as directed on the package; it should be pliable but still cold. Pat the chicken dry and cut it into even pieces. Rinse sliced leeks carefully in a bowl of water, lift them out to leave grit behind, and drain well. Heat the oven to 400°F (200°C).
Brown the chicken: Heat the oil in a large skillet over medium-high heat. Add the chicken in a single layer, working in batches if necessary, and brown for about 3 minutes, turning once. It does not need to be fully cooked yet. Transfer it to a clean plate; keep raw-chicken utensils and surfaces separate from cooked food.
Soften the vegetables: Reduce the heat to medium and add the butter, leeks, and carrots. Cook for 7–8 minutes, stirring occasionally, until the leeks are soft but not browned. If the pan seems dry or the leeks start to catch, lower the heat and add a tablespoon of water.
Make the sauce: Sprinkle the flour over the vegetables and stir for 1 minute. Gradually pour in the broth, stirring to remove lumps, then add the cream, Dijon, thyme, salt, and pepper. Bring to a gentle simmer and cook for 2–3 minutes, stirring, until the sauce thickens lightly.
Finish cooking the filling: Return the chicken and any juices on the plate to the pan. Simmer gently for 5–7 minutes, stirring occasionally, until the chicken reaches 165°F (74°C) at its thickest point on an instant-read food thermometer; this is the USDA FSIS safe minimum temperature for poultry. Taste the sauce and adjust the seasoning. Remove the pan from the heat and let the filling cool for 10 minutes so it is less likely to soften the pastry.
Assemble the pie: Spoon the filling into a 9-inch (23 cm) deep pie dish, leaving a little space at the top. Lay the pastry over the dish, trim excess, and press the edges against the rim to seal. Cut a small slit in the center for steam. Brush the top with egg wash, taking care not to let it run down the sides, where it can hinder the pastry from rising.
Bake and rest: Bake for 25–30 minutes, until the pastry is well risen and deep golden and the filling is bubbling at the edges. 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 settle and be easier to portion.

Tips

Clean leeks thoroughly: Dirt often collects between the layers. Slice first, then rinse and drain well. Use only the white and tender light-green parts for a mild, sweet flavor.
Keep the pastry cold: Warm puff pastry can become sticky and rise less evenly. If it softens while you assemble the pie, chill it briefly before baking.
Mind the sauce thickness: The filling should be creamy, not runny. Simmer it a little longer before adding it to the dish if it looks thin; it will also thicken slightly as it rests.
Use care with raw poultry: Wash hands, boards, and utensils after handling uncooked chicken, and do not reuse its plate for the cooked filling unless washed first.

Serving Suggestions

Serve the pie warm, after its short rest, with steamed green beans, peas, or a crisp green salad to balance the creamy filling. Roasted carrots or a modest serving of mashed potatoes also work well if you want a more substantial meal. Spoon portions carefully, since the center stays hot longer than the pastry.

Variations

For a deeper savory flavor, replace up to half the chicken with sliced mushrooms; cook them with the leeks until their released liquid has mostly evaporated. You can use boneless, skinless chicken breast instead of thighs, but check it with a thermometer and avoid simmering it longer than needed, as breast meat dries out more easily.

For a lighter filling, substitute whole milk for the heavy cream; the sauce will be less rich and may need an extra minute of simmering. A little chopped parsley can replace or accompany thyme. If you do not have puff pastry, use a pie-crust pastry sheet, following its package directions; it will make a more short, flaky crust rather than the airy layers of puff pastry.

Storage and Reheating

Refrigerate leftover pie within 2 hours of baking, covered or in an airtight container. It keeps for 3–4 days in the refrigerator. For longer storage, freeze portions in a freezer-safe container for up to 2 months; thaw overnight in the refrigerator before reheating. The pastry may be softer after freezing.

Reheat individual portions in a 350°F (175°C) oven until hot throughout, checking the center with a food thermometer and bringing leftovers to 165°F (74°C). Depending on portion size, this usually takes 20–30 minutes from chilled; cover loosely with foil if the pastry is browning too much. A microwave is quicker, but tends to soften the crust. Reheat only the portion you plan to eat.

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 with cold filling and pastry shortly before baking. The baking time may be a little longer if the filling is very cold; check that it is bubbling and heated through.

Can I use leftover cooked chicken?
Yes. Skip the browning and simmering steps for raw chicken. Make the leek-and-carrot sauce, then stir in about 3 cups (420 g) shredded cooked chicken and heat it through before assembling. Handle and store cooked chicken safely, and make sure the finished filling is hot throughout.

Why is my pie filling watery?
Leeks can hold rinse water, and vegetables release moisture as they cook. Drain the leeks well, simmer the sauce until lightly thickened before assembling, and avoid covering the pan tightly. If the filling seems loose, reduce it on the stovetop rather than relying on the pastry to absorb the excess liquid.

Can I freeze the pie before baking?
For best pastry texture, freeze the cooled filling separately and thaw it in the refrigerator, then top it with fresh, cold pastry and bake. A fully assembled unbaked pie can also be frozen, but pastry quality may suffer. Bake from frozen only if the pastry package and dish are suitable, allowing extra time and checking the center is safely hot.

What size dish should I use?
A 9-inch (23 cm) deep pie dish works well for this amount of filling. Leave a little headroom so bubbling sauce does not spill over. Set the dish on a baking sheet to catch any drips and make it easier to move in and out of the oven.
