Step-by-Step Instructions

Step 1: Make the flaky butter dough

In a large bowl, whisk together the flour, salt, and sugar. Toss in the cold butter cubes. Using a pastry cutter or your fingertips, cut the butter into the flour until you have pea- to almond-size pieces—visible chunks mean flakiness.

Drizzle in 6 tbsp ice water, tossing with a fork until the dough holds together when pinched. Add up to 2 tbsp more water if needed. Gather into a disk, wrap, and chill for 30 minutes while you prepare the filling.

Step 2: Poach the chicken with thyme

Place chicken thighs in a saucepan and cover with the chicken stock. Add the bay leaf and 3 thyme sprigs. Bring to a gentle simmer over medium heat and cook until the chicken is just cooked through, 12–15 minutes. Do not boil vigorously or the meat will toughen.

Transfer chicken to a plate to cool slightly. Strain and reserve 2 cups of the poaching liquid for the sauce (save the rest for another use). Shred or chop the chicken into bite-size pieces.

Step 3: Sauté the aromatics

Heat 3 tbsp butter in a 10-inch oven-safe skillet (cast iron works beautifully) over medium heat. Add onion, carrots, and celery with a pinch of salt. Cook, stirring occasionally, until softened and lightly golden at the edges, 6–8 minutes. Stir in the minced garlic and the remaining thyme leaves (1 tbsp); cook 1 minute until fragrant. If using wine or sherry, add it and simmer until almost evaporated, about 1 minute.

Step 4: Build a creamy thyme sauce

Sprinkle the flour over the vegetables and cook, stirring, for 1–2 minutes to form a blond roux. Slowly whisk in the reserved 2 cups poaching liquid, then the heavy cream. Add Dijon and a pinch of nutmeg, if using. Simmer, stirring, until the sauce is smooth and thick enough to coat a spoon, 3–5 minutes. Season with 1 tsp kosher salt and 1/2 tsp black pepper (adjust to taste).

Step 5: Finish the filling

Stir in the shredded chicken, peas, parsley, and lemon juice. Taste and adjust seasoning. Remove from heat and let the filling cool for 10 minutes—this quick cool helps prevent a soggy crust.

Step 6: Assemble the pie

Heat the oven to 400°F (200°C). If your filling is in a skillet you can bake in, leave it there; otherwise, transfer filling to a 9-inch deep-dish pie plate. On a lightly floured surface, roll the chilled dough into a 12-inch circle about 1/8 inch thick. Drape it over the filling. Trim to a 1-inch overhang, fold under, and crimp. Cut 4–5 slits in the center for steam. Whisk egg with milk and brush all over the crust. Sprinkle with flaky salt if you like.

Step 7: Bake until deeply golden and shattering

Set the pie on a rimmed baking sheet to catch drips. Bake at 400°F for 35–40 minutes, rotating once, until the crust is a deep golden brown and the filling is bubbling through the vents. If the edges brown too quickly, tent loosely with foil. Let rest 15 minutes before serving so the filling sets and the crust stays crisp.

Pro Tips

• Keep it cold: Cold butter and a chilled dough are key to visible layers and a shattering crust.
• Reserve that stock: Poaching the chicken in stock and using it for the sauce builds deeper flavor.
• Cool the filling slightly: A 10-minute cool prevents melting the butter in your crust on contact.
• Bake on a sheet: It promotes even browning and catches any bubbling overflow.
• Shine and salt: Egg wash plus a pinch of flaky salt delivers color, crunch, and savoriness.

Variations

• Cheddar–Chive Crust: Add 1/2 cup finely shredded sharp white cheddar and 1 tbsp minced chives to the flour before cutting in butter.
• Mushroom–Tarragon: Sauté 8 oz sliced cremini with the vegetables and swap thyme for 1 tsp chopped tarragon.
• Puff Pastry Top: Short on time? Use a 10–12 inch round of store-bought puff pastry; bake at 400°F until deeply golden, 30–35 minutes.

Storage & Make-Ahead

Refrigerate leftovers, covered, for up to 3 days. Reheat at 350°F (175°C) until hot and crisp, 20–25 minutes. To make ahead, the dough can be refrigerated 2 days or frozen 2 months. The filling can be made 1 day ahead; cool completely and refrigerate. To freeze an unbaked pie, assemble, wrap tightly, and freeze up to 2 months. Bake from frozen at 400°F for 60–70 minutes, tenting if needed, until the crust is deeply golden and the center is bubbling.
