Chicken and Leek Pie

Featured in: Evening Family Suppers

This classic British comfort dish features succulent chicken pieces paired with gently sautéed leeks, sweet carrots, and crispy smoked bacon, all bound together in a velvety homemade white sauce enriched with double cream and Dijon mustard. The filling is encased in buttery puff pastry that bakes to golden perfection, creating a crisp, flaky lid that protects the rich, savory interior within.

I used to watch the rain slide down the kitchen window while the scent of leeks softening in butter filled the house. My first attempt at this pie ended with a soggy bottom because I was too impatient to let the filling cool. Now I treat the cooling time like a sacred ritual for the perfect crust. It is the kind of meal that makes a Tuesday night feel like a celebration.

One chilly November evening I served this to a friend who claimed they did not like leeks. They ended up scraping the bottom of the dish for every last drop of the mustard infused sauce. We sat there for hours talking over the remnants of the flaky pastry crumbs. It is officially the dish I make when I want someone to feel truly looked after.

Ingredients

  • Chicken thighs: These stay much juicier than breasts when baked under a heavy pastry lid.
  • Smoked bacon lardons: These provide small pops of salty smoke throughout the creamy filling.
  • Leeks: Slicing them into rounds allows them to soften into sweet ribbons of flavor.
  • Carrots and celery: These provide a necessary earthy base and a bit of texture.
  • Unsalted butter: This is the foundation of the roux and adds a rich velvety finish.
  • Plain flour: It acts as the thickening agent to turn the stock into a sauce.
  • Whole milk: Using full fat milk ensures the filling is creamy and satisfying.
  • Chicken stock: This deepens the savory profile and binds the ingredients together.
  • Double cream: Adding this at the very end brings a luxurious bistro quality to the pie.
  • Dijon mustard: A small amount adds a subtle tang that balances the rich cream.
  • Fresh thyme: This herb provides a floral woodsy aroma that complements the chicken.
  • Ready rolled puff pastry: This is a reliable way to get a spectacular golden crunch every time.
  • Egg wash: Brushing the top ensures the pie comes out of the oven looking professional.

Instructions

Preheating and preparation:
Set your oven to 200C and get your pie dish ready so you can assemble everything quickly. Ensure all your vegetables are chopped and the chicken is cut into even pieces.
Crisping the bacon:
Toss the bacon into the pan and watch it sizzle until it is golden and the fat has rendered. This smoky fat will be the base for all the other flavors.
Browning the chicken:
Sizzle the chicken pieces in that smoky bacon fat until they develop a beautiful golden crust. You are not cooking them all the way through yet just locking in the juices.
Softening the vegetables:
Stir in the leeks and carrots until they are soft and the kitchen smells amazing. Add the garlic at the very end so it does not burn.
Creating the sauce:
Sprinkle in the flour and whisk the milk and stock slowly to create a thick velvety gravy. Keep stirring to ensure there are no lumps in your roux.
Enriching the filling:
Stir the meat back into the cream with a dollop of mustard and fresh thyme. Let the mixture cool for a few minutes so it does not melt the pastry.
Applying the pastry:
Drape the puff pastry over the dish and brush it with egg for a professional shine. Cut small slits in the center to allow the steam to escape during baking.
The final bake:
Watch through the oven door as the pastry puffs up and turns a deep amber color. Let it stand for five minutes before serving to allow the sauce to set.

I remember the sound of the pastry shattering under the knife the last time I made this for my sister. We did not even bother with plates at first just picking off the golden corners while it was still steaming. It reminded me that the best food is often the messiest and most shared.

The Secret to the Savory Sauce

The addition of Dijon mustard might seem small but it cuts through the richness of the cream perfectly. I discovered this by accident when I ran out of plain mustard and reached for the tangy jar instead. It adds a sophisticated depth that balances the smoky bacon and sweet leeks.

Personalizing Your Pie

You can easily toss in a handful of frozen peas or even some sweetcorn if you want more color. I sometimes swap the chicken stock for a bit of dry white wine to make it feel more like a bistro meal. It is a very forgiving recipe that welcomes your own kitchen experiments.

Serving Suggestions and Storage

This pie is a complete meal on its own but it loves a side of buttery mashed potatoes. Leftovers actually taste even better the next day as the flavors have time to mingle in the fridge.

  • Reheat in the oven to keep the pastry crisp rather than using the microwave.
  • A simple green salad with a sharp vinaigrette provides a nice contrast to the heavy cream.
  • Make sure to press the edges of the pastry firmly against the rim to prevent leaks.

Recipe Questions & Answers

Can I make the filling ahead of time?

Absolutely. Prepare the filling completely and refrigerate for up to 24 hours before topping with pastry and baking. This actually improves the flavor as the ingredients meld together.

What vegetables work well in this pie?

Beyond the classic leeks and carrots, you can add frozen peas for sweetness, mushrooms for earthiness, or even parsnips for a winter twist.

Can I freeze this pie?

Yes, either freeze unbaked (wrap tightly) or freeze leftovers after baking. Thaw overnight in the refrigerator before reheating at 180°C until piping hot throughout.

How do I know when the pie is done?

The pastry should be deep golden brown and you should see sauce bubbling through the steam vents. The internal temperature should reach 74°C.

What sides complement this pie?

Buttery mashed potatoes are traditional, but it also pairs beautifully with roasted seasonal vegetables or a crisp green salad with vinaigrette.

02 2 medium carrots, peeled and diced
03 2 celery stalks, diced
04 2 cloves garlic, minced
05 1 small onion, finely chopped

Sauce & Dairy

01 3.5 tablespoons unsalted butter
02 1/3 cup all-purpose flour
03 1 2/3 cups whole milk
04 3/4 cup plus 2 tablespoons chicken stock
05 1/3 cup heavy cream
06 1 teaspoon Dijon mustard
07 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
08 Salt and freshly ground black pepper to taste

Pastry

01 1 sheet ready-rolled puff pastry, approximately 11.3 ounces

How-To Steps

Step 01

Preheat oven and prepare bacon: Preheat the oven to 400°F. In a large frying pan over medium heat, cook the bacon until golden and crisp, approximately 5-7 minutes. Remove with a slotted spoon and set aside on a paper towel.

Step 02

Brown the chicken: In the same pan with bacon drippings, add the chicken pieces and brown on all sides for 5-6 minutes until golden. Transfer to a plate and reserve.

Step 03

Sauté aromatics and vegetables: Add butter to the pan, then stir in the onions, leeks, carrots, and celery. Sauté for 8-10 minutes until softened. Add minced garlic and cook for 1 minute more until fragrant.

Step 04

Create roux: Sprinkle flour over the vegetables, stirring continuously for 1 minute to cook out the raw flour taste and create a light roux base.

Step 05

Build the sauce: Gradually pour in the milk and chicken stock while stirring constantly to prevent lumps from forming. Bring to a simmer and cook for 3-4 minutes until the sauce thickens to a light cream consistency.

Step 06

Combine filling ingredients: Stir in the reserved bacon, browned chicken, heavy cream, Dijon mustard, and thyme. Season to taste with salt and pepper. Remove from heat and allow to cool for 10 minutes.

Step 07

Transfer to pie dish: Pour the cooled filling into a large pie dish with approximately 1.6 quart capacity, distributing evenly.

Step 08

Top with pastry: Unroll the puff pastry and lay it over the filling. Trim any excess overhang and press the edges firmly to seal. Cut 2-3 small slits in the top surface to allow steam to escape. Brush generously with beaten egg.

Step 09

Bake until golden: Bake for 30-35 minutes until the pastry is deep golden and crisp. Allow to rest for 5 minutes before serving.
