Why this recipe works
This creamy chicken and leek pie is ideal for colder evenings. Tender chicken, soft leeks and mushrooms combine in a rich, comforting sauce beneath a golden pastry top. The flavours are mild, comforting and easy to adapt to your taste.
It’s also flexible: you can add extra vegetables, swap cuts of meat, or tweak seasonings to make it meatier, lighter or more vegetable-forward.
Ingredients to make Chicken and Leek Pie

- Chicken – Chicken breasts work well, or use boneless thighs for juicier results.
- Leeks – Use the white and light green parts for a gentle onion-like flavour.
- White mushrooms – Also called button mushrooms, they add umami and texture.
- Garlic cloves – Adds depth to the filling.
- Italian herbs – A mix of thyme, basil, oregano and rosemary gives a classic savoury note.
- Whole-grain mustard – Gives a mild bite; Dijon is a fine substitute.
- Cooking cream or soya/oat cream – Creates the creamy sauce; use your preferred dairy or plant-based cream.
- Butter – Unsalted allows you to control seasoning.
- Salt and black pepper – To taste.
- Puff pastry – One sheet; gluten-free or regular pastry both work. Mashed potato can be used as an alternative topping.
See recipe card below for exact quantities and full details.
Substitutions
- Protein: Use ham, beef, or tofu instead of chicken.
- Vegetables: Add or swap in onions, peas, celery or carrots.
- Herbs & spices: Try tarragon, thyme, oregano, parsley or basil to change the flavour profile.
- Mustard: Dijon works well in place of whole-grain mustard.
- Pastry: Replace puff pastry with mashed potato topping for a cottage-pie style finish.
Variations
- Spicy: Add a pinch of chilli powder or chopped fresh chilli for heat.
- Deluxe: Stir in chopped bacon before baking and brush the pastry with butter once out of the oven.
- Kid-friendly: Include your child’s preferred vegetables and keep seasoning mild.
How to make Chicken and Leek Pie

Step 1: Preheat the oven to 200°C (405°F). Slice the white and pale green parts of the leeks, chop the mushrooms and cut the chicken into bite-sized pieces.

Step 2: Melt butter in a frying pan and cook the leeks, mushrooms, garlic and Italian herbs for 2–3 minutes until slightly softened.

Step 3: Add the chicken and cook for 5–6 minutes until it’s no longer pink on the outside.

Step 4: Stir in whole-grain mustard and cooking cream, then season with salt and pepper to taste. Simmer briefly until the sauce begins to thicken.

Step 5: Transfer the chicken and leek mixture into a pie dish, spreading it evenly.

Step 6: Roll out the puff pastry and place it over the filling. Trim any excess pastry, press the edges to seal and make a few slits on top to let steam escape. Bake for about 30 minutes until the pastry is golden and crisp.
Hint: For extra colour and shine, brush the pastry with an egg wash before baking.
Leftovers
Store leftover pie in an airtight container in the fridge for 2–3 days. Reheat portions in the microwave or oven until heated through.
To freeze: It freezes best before baking. Wrap the assembled pie in cling film and freeze for up to two months. Cook from frozen or thaw before baking.

To store: Keep in an airtight container in the fridge for 2–3 days and reheat before serving.
To freeze: Best frozen before baking. Wrap well and freeze up to two months.
Tip 1: The chicken will finish cooking in the oven, so it doesn’t need to be fully cooked in the pan.
Tip 2: If you prefer a thinner sauce, stir in a little chicken stock or broth.
Tip 3: Make individual pies by dividing the filling among small ovenproof dishes and topping each with pastry.
