🥗 Ingredients

The Pastry Crust

  • 2 1/2 cups All-purpose flour (chilled)
  • 1 cup Unsalted butter (cold, cubed into 1/2 inch pieces)
  • 1/2 cup Buttermilk (ice cold)
  • 1 teaspoon Kosher salt

The Filling

  • 1 lb Chicken breast or thighs (cooked and shredded or cubed)
  • 6 tablespoons Unsalted butter
  • 1 medium Yellow onion (finely diced)
  • 2 medium Carrots (peeled and sliced into rounds)
  • 2 pieces Celery stalks (thinly sliced)
  • 3 pieces Garlic cloves (minced)
  • 1/2 cup All-purpose flour (for the roux)
  • 2 cups Chicken stock (low sodium, high quality)
  • 1/2 cup Heavy cream
  • 1 cup Frozen peas (thawed)
  • 1 tablespoon Fresh thyme (leaves removed from stems)
  • 2 tablespoons Fresh parsley (finely chopped)

The Finish

  • 1 large Egg (beaten with 1 tbsp water for egg wash)
  • 1 pinch Sea salt (for sprinkling on crust)

👨‍🍳 Instructions

  1. 1

    Prepare the crust: In a large bowl, whisk flour and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized chunks of butter remaining.

  2. 2

    Slowly drizzle in the cold buttermilk, tossing with a fork until a shaggy dough forms. Turn onto a floured surface, gently knead 2-3 times, wrap in plastic, and chill for at least 1 hour.

  3. 3

    Preheat your oven to 400°F (200°C). Prepare a 9-inch deep-dish pie plate or a 2-quart baking dish.

  4. 4

    In a large skillet or Dutch oven, melt 6 tablespoons of butter over medium heat. Add the onions, carrots, and celery. Sauté for 8-10 minutes until the vegetables are softened and the onions are translucent.

  5. 5

    Stir in the minced garlic and cook for just 60 seconds until fragrant. Sprinkle the 1/2 cup of flour over the vegetables.

  6. 6

    Cook the flour-vegetable mixture for 2 minutes, stirring constantly to toast the flour slightly without burning it; this removes the 'raw' flour taste.

  7. 7

    Gradually whisk in the chicken stock and heavy cream. Simmer over medium-low heat for 5-7 minutes until the sauce has thickened into a rich gravy that coats the back of a spoon.

  8. 8

    Fold in the cooked chicken, peas, thyme, and parsley. Season generously with salt and black pepper to taste. Remove from heat and let cool slightly.

  9. 9

    On a floured surface, roll out your chilled dough to about 1/4 inch thickness, ensuring it is at least 1 inch wider than your baking dish.

  10. 10

    Pour the chicken filling into the baking dish. Carefully drape the pastry over the top. Trim the excess, fold the edges under, and crimp with a fork or your fingers to seal.

  11. 11

    Cut 3-4 small slits in the center of the crust to allow steam to escape. Brush the entire surface with the egg wash and sprinkle with a pinch of sea salt.

  12. 12

    Place the dish on a baking sheet (to catch drips) and bake for 35-45 minutes, or until the crust is a deep golden brown and the filling is bubbling through the vents.

  13. 13

    Allow the pie to rest for 10-15 minutes before serving. This crucial step lets the sauce set so it doesn't run when sliced.

💡 Chef's Tips

Keep your butter and buttermilk ice cold; this is the secret to a flaky, layered crust. Don't over-mix the dough; visible bits of butter are what create steam pockets for flakiness. If the crust edges brown too quickly, cover them with small strips of aluminum foil halfway through baking. For a time-saver, use a high-quality store-bought rotisserie chicken for the filling. Always taste your filling before topping with the crust; the gravy should be slightly over-seasoned as the crust will mellow it out.

🍽️ Serving Suggestions

Serve with a crisp, bright green salad tossed in a lemon vinaigrette to cut through the richness. A side of roasted asparagus or steamed green beans adds a nice textural contrast. Pair with a chilled glass of buttery Chardonnay or a crisp dry cider. For a true feast, serve alongside a small bowl of extra cranberry sauce or onion jam.
