When celebrating St Patrick's Day, I love Corned Beef and Cabbage as much as most people, but this year I wanted to make something different. This is my version a traditional Irish Chicken and Leek Pie. This pie is full of fresh veggies like leeks, zucchini, and carrots. And the sauce is so simple but so flavorful - chicken stock, mustard, and sour cream (or yogurt!) The pie crust is a little "keep it simple" trick, by using puff pastry instead of pie dough. Feel free to get creative by cutting out shapes, strips, or stacking squares (like I did!) Happy St Patrick's Day, friends!
Heat the Olive Oil on the stove, in a pan, over a medium heat.
Add the Leeks and Carrots and sauté for 5 minutes.
Add the Chicken and cook for 5 minutes, stirring occasionally. (The Chicken does not need to be fully cooked in this step. It will cook more in the next step and in the oven too.)
Add the Stock and Zucchini; mix well. Bring to a boil then reduce heat to low. Simmer for 20 minutes, without a lid, until the liquid reduces by half.
Remove the pan from the heat and add Mustard and Sour Cream; mix well. This is your Chicken Pie Filling.
Transfer the Chicken Pie Filling into the pie dish.
In a small bowl whisk Egg and Water together. This is your Egg Wash.
Top the pie with puff pastry, pierce the pastry with a knife to create a few holes for steam to escape, and brush with Egg Wash. (Feel free to get creative with your puff pastry, add it in squares, strips, cut out designs, etc)
Bake at 400°F for 15 minutes or until the pastry is golden.
Serve with mashed potatoes or Irish Colcannon (half mashed potatoes, half cabbage.)
