Mary Berry Chicken Leek Pie is a savoury dish made with cooked chicken pieces, softened leeks, and a creamy béchamel-style sauce, all baked under puff pastry. It’s a traditional British comfort food known for its hearty filling and crisp, golden topping.
500g cooked chicken (shredded or diced)
2 large leeks (thinly sliced)
1 onion (finely chopped)
2 tbsp butter
2 tbsp flour
400ml chicken stock
150ml milk
1 tsp mustard
Salt and pepper to taste
Handful of fresh parsley (optional)
1 sheet ready-rolled puff pastry
1 egg (beaten for glaze)
Slice the leeks thinly, chop the onion, and set aside so everything is ready for cooking.
Add butter to a pan and gently cook the leeks and onion until soft and fragrant, allowing their natural sweetness to develop.
Stir in the flour and cook for a minute, then gradually add the chicken stock and milk, whisking to create a smooth, thick sauce.
Stir the cooked chicken into the sauce along with mustard, seasoning, and parsley, mixing until everything is well combined.
Spoon the warm filling into a pie dish, spreading it evenly so the pastry sits neatly on top.
Lay the puff pastry sheet gently over the dish, pressing the edges to seal and trimming any excess. Brush with beaten egg.
Bake at 200°C (400°F) for about 25–30 minutes until the pastry turns golden, crisp, and beautifully puffed.
Let the pie sit for a few minutes before slicing so the filling settles and serves neatly.
