Chicken and Leek Pie

There's something about the smell of bacon crisping in a pan that makes you stop whatever you're doing and pay attention. Years ago, a friend handed me this recipe scribbled on the back of an envelope, claiming it was her secret weapon for dinner parties. I was skeptical—chicken pie sounded ordinary until I tasted it: tender chicken, leeks that had somehow become sweet and subtle, and pastry so golden it practically glowed. That first bite completely rewired what comfort food meant to me.

I made this for my partner on a rainy November evening when neither of us felt like going out, and we ended up eating it straight from the dish while watching something forgettable on television. That's when I realized this wasn't really about impressing anyone—it was about creating the kind of meal that makes you want to stay home, to linger over dinner, to feel taken care of.

Ingredients

• Boneless, skinless chicken thighs (500 g): Thighs stay juicy where breast meat dries out; they're more forgiving and full of flavor, which is exactly what you want in a creamy sauce.
• Smoked bacon lardons (100 g): The smoke matters more than you'd think—it's the secret note that makes people ask what that delicious flavor is.
• Leeks (2 large, sliced into 0.5 cm rounds): Slice them carefully and rinse between the layers; grit hiding in there will ruin everything, so take the extra minute.
• Carrots (2 medium, diced): Dicing them uniformly means they cook evenly and add natural sweetness without overpowering the leeks.
• Celery (2 stalks, diced): It's easy to skip, but celery adds depth that you won't consciously notice but definitely will miss if it's gone.
• Garlic (2 cloves, minced): Add it after the softer vegetables are nearly cooked so it doesn't burn and turn bitter.
• Onion (1 small, finely chopped): The base of flavor; don't rush this part, let it soften completely before moving on.
• Unsalted butter (50 g): Use real butter here—it matters for the roux and the overall taste.
• Plain flour (40 g): This thickens the sauce; cooking it for a minute removes that raw flour taste that can hide in poorly made pies.
• Whole milk (400 ml): Whole milk creates a creamier sauce than lower fat versions.
• Chicken stock (200 ml): Good stock makes a noticeable difference; if yours is weak, add a little less and taste as you go.
• Double cream (100 ml): This is the luxury touch that makes people wonder what restaurant you went to.
• Dijon mustard (1 tsp): A small amount adds complexity without making anything taste like mustard.
• Fresh thyme (1 tsp leaves): Fresh thyme is worth seeking out; dried works but lacks that bright, herbal lift.
• Salt and black pepper: Taste as you season; the bacon adds saltiness, so go easy at first.
• Ready-rolled puff pastry (1 sheet, about 320 g): Room-temperature pastry is easier to handle and bakes more evenly than cold pastry.
• Beaten egg (1): The egg wash is what gives that beautiful golden shine—don't skip it.

Instructions

Get your oven ready and start with bacon:

Preheat to 200°C (180°C fan) / 400°F / Gas Mark 6. In a large frying pan over medium heat, cook the bacon until it's golden and crisp—you want it to actually make a sound when you bite it. Scoop it out with a slotted spoon and set aside on paper towels.

Brown the chicken properly:

In the same pan with all those bacon drippings (don't you dare wipe that out), add the chicken pieces in a single layer. Let them sit for 2–3 minutes before stirring so they actually brown instead of steaming. Transfer to a plate after 5–6 minutes when they're golden on at least two sides.

Build the flavor base:

Add butter to the pan, then immediately add the onions, leeks, carrots, and celery. Sauté for 8–10 minutes, stirring occasionally—you're looking for everything to turn soft and the leeks to become translucent and almost silky. Add the garlic and cook for just 1 more minute so it releases its aroma without burning.

Make the roux and sauce:

Sprinkle the flour over the vegetables and stir constantly for 1 minute—this cooks out the raw flour taste and keeps lumps from forming later. Gradually pour in the milk and stock while stirring, working slowly enough that you catch any lumps forming. Bring to a gentle simmer and cook for 3–4 minutes until the sauce coats the back of a spoon.

Bring it all together:

Stir the bacon, chicken, double cream, mustard, and thyme back into the sauce. Taste and season with salt and pepper—remember the bacon is already salty, so adjust carefully. Remove from heat and let cool for 10 minutes so the pastry doesn't crack when it hits the hot filling.

Assemble and bake:

Pour the filling into your pie dish. Unroll the pastry and lay it over the top, pressing the edges to seal—you can crimp them with a fork if you're feeling fancy. Cut three or four small slits in the top for steam to escape, brush generously with beaten egg until it's glossy, then bake for 30–35 minutes until the pastry is deeply golden and crisp.

Rest before serving:

Let the pie stand for 5 minutes after it comes out of the oven—this allows the filling to set slightly so it won't run all over the plate when you cut into it.

My neighbor once said this pie tasted like her childhood, and watching her face as she took the first bite reminded me that cooking is really about sending someone a message without words. This dish says you're worth the effort, you're welcome here, this moment matters.

When to Make This

This is the kind of meal that transforms an ordinary weeknight into something worth remembering. It's also brilliant for feeding a small group without fussing over individual plating—one pie in the center of the table, everyone serves themselves, and you get to enjoy the company instead of being stuck in the kitchen.

Making It Your Own

The beauty of this pie is how forgiving it is. Swap the leeks for mushrooms if you prefer, add a handful of frozen peas for color, or stir in a splash of white wine when you make the sauce for a brighter flavor. Some people add tarragon instead of thyme, others use half the milk and substitute dry white wine—the structure stays solid while the personality changes.

Serving and Storage

Serve this straight from the oven with buttery mashed potatoes or a crisp green salad alongside—something fresh cuts through the richness beautifully. Leftover pie keeps for three days in the fridge and actually improves as the flavors meld; reheat gently in a 180°C oven until warm through.

• For a genuine shortcut on busy nights, rotisserie chicken cuts your prep time in half and still tastes wonderful.
• If you're making this ahead, assemble everything except the pastry, cover, and refrigerate for up to 24 hours—add 5–10 minutes to the baking time if baking from cold.
• Leftover pie is just as good cold the next day, straight from the fridge with a fork at the kitchen counter.

There's genuine magic in sliding a golden pie from the oven and watching someone's face light up at the smell. That's what this recipe is really about.

Recipe Questions & Answers

→ Can I use chicken breast instead of thighs?

Yes, you can substitute chicken breast, but thighs provide more flavor and stay juicier during cooking. If using breast, reduce the browning time slightly to prevent drying out.

→ How do I prevent the pastry from becoming soggy?

Allow the filling to cool for at least 10 minutes before topping with pastry. The steam vents cut into the pastry also help release moisture during baking, keeping the crust crisp.

→ Can I make this ahead of time?

Absolutely. Prepare the filling up to 24 hours in advance and refrigerate. Add the pastry and bake just before serving, adding 5-10 minutes to the baking time if starting from cold.

→ What can I substitute for leeks?

If leeks aren't available, use 2 large onions or 3-4 shallots. The flavor will be slightly different but still delicious. You could also add sliced mushrooms for earthy depth.

→ Can I freeze this pie?

Yes, assemble the pie without baking, wrap tightly, and freeze for up to 3 months. Bake from frozen at the same temperature, adding 15-20 minutes to the cooking time.

→ How do I know when the pie is fully cooked?

The pastry should be deep golden brown and crisp. The filling should be bubbling around the edges. If the pastry browns too quickly, cover loosely with foil and continue baking.
