Chicken, Leek, and Mushroom Pie – a lovely, savory pie with a chicken, leek, mushroom and potato filling. A crispy phyllo topping makes the dish lighter.

If you like leeks, mushrooms, potatoes, and chicken, then you are going to really like this Chicken, Leek, and Mushroom Pie!

Although this savory pie with its roots in Irish cookery is quite filling and satisfying, it’s at the same time light. That’s because it uses phyllo pastry instead of a traditional pie crust for its topping.

The phyllo is brushed with lots of butter and when cooked, it becomes a beautiful golden brown color with a crispy texture. It’s practically as light as a potato chip.

And the filling! Oh, my. It’s just a lovely combination of chicken, leeks, mushrooms, and potatoes with a bit of milk and some sage for seasoning.

This Chicken, Leek, and Mushroom Pie makes a lovely centerpiece for a family Sunday dinner. I served it with green beans on the side and hot rolls with Irish butter.

How to Make Chicken, Leek, and Mushroom Pie

Preheat the oven to 350 degrees.

Peel the potatoes and cut into approximately 3/4” dice. Cook in boiling water for 5 minutes. Drain and set aside.

Leeks and mushrooms sliced on a cutting board.

Cut the chicken breast into approximately 1/2” cubes. Wash the leek very well and slice it crosswise into thin disks. Clean the mushrooms and slice them into pieces the same thickness as the slices of leek.

In a large skillet, melt half the butter over medium high heat. Add the chicken and cook for 5 minutes or until browned.

Cooked chicken with leeks and mushrooms added.

Add the leek and mushrooms and cook for an additional 3 minutes, stirring constantly.

Flour sprinkled over cooked chicken, leeks, and mushrooms.

Sprinkle the flour over the chicken, leek, and mushrooms, and cook for another one minute, stirring constantly.

Adding milk to the chicken, leek, and mushroom mixture.

Gradually add the milk while stirring. Bring to a boil.

Adding mustard, sage, and potatoes to the skillet.

Add the mustard, sage, and potatoes. Season with salt and pepper to taste. Reduce the heat and simmer the mixture for 10 minutes.

While the pie filling is simmering, melt the remaining butter in a small saucepan.

Lining a baking dish with phyllo pastry.

Line a deep pie dish or casserole dish with half the phyllo sheets.

Chicken filling added on top of the phyllo pastry.

Spoon the mixture into the dish.

Cover with a sheet of phyllo and brush with a little of the melted butter. Repeat with a second sheet of phyllo. Cut the remaining phyllo pastry into strips and fold and drape them on top of the pie creating a ruffled look. Brush the strips with the remaining melted butter.

Finished chicken, leek, and mushroom pie.

Cook for 45 minutes, or until the phyllo pastry is golden brown and crisp. Serve hot.
