Jamie Oliver Chicken and Mushroom Pie with Puff Pastry
Print Recipe

A classic British comfort pie featuring tender shredded chicken and earthy mushrooms in a rich, creamy thyme sauce, all topped with golden, flaky puff pastry. The filling is deeply savory with a velvety texture, while the pastry delivers a satisfying crunch and buttery finish.

Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1 medium yellow onion, finely diced (about 1 cup)
  • 8 ounces (225g) cremini mushrooms, sliced 1/4-inch thick
  • 2 cloves garlic, minced
  • 3 tablespoons all-purpose flour
  • 1 cup (240ml) low-sodium chicken stock
  • 1/2 cup (120ml) heavy cream
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
  • 2 cups (about 12 ounces / 340g) cooked chicken breast, shredded into bite-sized pieces
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon freshly ground black pepper
  • 1 sheet (about 9x9 inches / 225g) frozen puff pastry, thawed according to package directions
  • 1 large egg, beaten with 1 tablespoon water (for egg wash)

Instructions

  1. Preheat your oven to 400°F (200°C). Place a rack in the center position. Melt the butter in a large (10-inch) oven-safe skillet or sauté pan over medium heat. When the butter foams and stops sizzling, add the diced onion and cook, stirring occasionally, until softened and translucent, about 4-5 minutes. This step builds the aromatic base of the filling and prevents raw onion flavor.
  2. Add the sliced mushrooms to the pan. Increase the heat to medium-high and cook, stirring often, until the mushrooms have released their moisture and begun to brown, about 6-8 minutes. The browning (Maillard reaction) deepens the savory, umami character of the pie. If the pan seems dry, add a splash of water or a small knob of extra butter.
  3. Stir in the minced garlic and cook for 30 seconds until fragrant, being careful not to burn it. Sprinkle the flour evenly over the mushroom mixture and stir constantly for 1 minute. This roux will absorb excess fat and thicken the sauce later.
  4. Slowly pour in the chicken stock while whisking vigorously to prevent lumps. Bring the mixture to a gentle simmer, then add the heavy cream and thyme leaves. Cook, stirring occasionally, until the sauce thickens enough to coat the back of a spoon, about 2-3 minutes. The sauce should be silky and smooth, not pasty.
  5. Fold in the shredded chicken, salt, and pepper. Taste and adjust seasoning if needed. Remove the pan from heat. The filling should be thick but not dry; if it seems too tight, stir in a tablespoon of stock or milk. Allow the filling to cool for 5 minutes — this prevents the puff pastry from steaming before it bakes.
  6. On a lightly floured surface, unfold the thawed puff pastry sheet. Using a rolling pin, gently roll it out to a rectangle about 1/8-inch thick, just slightly larger than the skillet opening. If using a pie dish (8×8-inch or similar), trim the pastry to overhang by 1/2 inch all around.
  7. Lay the pastry over the filling, letting it drape naturally. Press the edges gently against the rim of the skillet or dish to seal. If using a pie dish, crimp the edges with a fork or your fingers. Cut 3-4 small slits in the top of the pastry to allow steam to escape — this prevents a soggy bottom and ensures even browning.
  8. Brush the top of the pastry evenly with the egg wash, being sure to coat the edges. This creates a glossy, deep golden crust. For extra crunch, you can sprinkle a pinch of flaky sea salt over the egg wash.
  9. Place the skillet or pie dish on a baking sheet to catch any drips. Bake in the preheated oven for 25-30 minutes, until the puff pastry is puffed, deeply golden, and the filling is bubbling visibly through the steam vents. If the pastry browns too quickly, tent loosely with foil after 15 minutes.
  10. Remove from the oven and let the pie rest for 10 minutes before serving. This allows the sauce to settle and thicken slightly, making slices easier to serve. The internal temperature of the filling should register at least 165°F (74°C) if you want to double-check doneness.
  11. Serve the pie in bowls or plates, spooning any extra sauce from the bottom over the pastry. Garnish with a few fresh thyme leaves if desired. Enjoy the contrast of the crisp, buttery pastry and the creamy, savory filling.

Notes

Storage: Refrigerate leftover pie in an airtight container for up to 3 days. Freezing: Assemble the pie (without egg wash) and freeze unbaked for up to 3 months. Bake from frozen, adding 10-15 minutes to the cook time. Reheating: Reheat individual portions in a 350°F (175°C) oven for 10-12 minutes, or until the pastry crisps and the filling is hot. Avoid microwaving as it will make the pastry soggy.
