Ingredients

The Pie Filling & Crust

  • 600 g Chicken Breast or Thigh Thighs stay juicier during the bake; cut into bite-sized chunks.
  • 1 sheet Puff Pastry Store-bought (all-butter) works best for a flaky lid.
  • 2 Large Leeks or Onions Leeks add a lovely sweetness to chicken pies.
  • 250 g Mushrooms Optional; chestnut mushrooms add great earthy flavor.
  • 300 ml Chicken Stock Use high-quality stock for a richer gravy.
  • 100 ml Double Cream Adds that "creamy" signature finish to the filling.
  • 2 tbsp Plain Flour To thicken the sauce into a roux.
  • 1 tbsp Fresh Thyme or Parsley Fresh herbs make a massive difference in aroma.
  • 1 Large Egg Beaten, for the egg wash to get that golden crust.

The Creamy Mash

  • 1 kg Maris Piper or Yukon Gold Use starchy potatoes for the fluffiest mash.
  • 50 g Unsalted Butter Don't be shy—butter is the secret to "creamy."
  • 100 ml Whole Milk or Cream Warm it up before adding to keep the potatoes hot.
  • _ _ Salt & Black Pepper Season generously at every stage.

Instructions

The Creamy Mash

  1. Boil the Potatoes:

    Place chopped potatoes in a large pot of cold salted water. Bring to a boil, then simmer for 15–20 minutes until tender.

  2. Steam Dry:

    Drain the potatoes in a colander, then return them to the hot pot for 1 minute (off the heat) to let excess moisture evaporate.

  3. Mash:

    Use your masher or ricer until smooth. Fold in the butter and warm milk/cream. Season generously with salt and white pepper. Set aside (keep covered).

The Chicken Filling

  1. Sear the Chicken:

    In your deep skillet, heat a splash of oil. Brown the chicken chunks in batches until golden (they don't need to be fully cooked yet). Remove and set aside.

  2. Sauté Aromatics:

    In the same pan, melt a knob of butter. Add the leeks (and mushrooms, if using) and sauté for 5–8 minutes until soft and translucent.

  3. Make the Sauce:

    Stir in the flour and cook for 1–2 minutes to toast it. Gradually pour in the chicken stock, whisking constantly to avoid lumps. Bring to a simmer until thickened.

  4. Combine:

    Stir in the double cream, fresh herbs, and the browned chicken. Season to taste.

Assembly & Baking

  1. Fill:

    Pour the chicken mixture into your Large Baking Dish. Let it cool for 10 minutes (this prevents the pastry from melting instantly).

  2. Top:

    Unroll the puff pastry and drape it over the dish. Trim the edges, press down with a fork to seal, and cut a small slit in the center for steam.

  3. Glaze & Bake:

    Brush the top thoroughly with the beaten egg wash. Bake at 200°C (400°F) for 25–30 minutes until the pastry is risen and deep golden brown.

Recipe Notes

Serving & Presentation

  • The Plate: Place a generous scoop of mash off-center; create "swirls" with a spoon to catch the light.

  • The Pie: Slice the pastry lid cleanly and perch it at an angle over the creamy filling to keep it crisp.

  • Color: Add a pop of green with fresh parsley or chives.

  • The Side: Serve with steamed broccoli or peas to cut through the richness.
