This is a ground chicken and mushroom pie with a puff pastry crust and a cream-thickened sauce. It makes four individual pies in one 80-minute session, which means you can have ready-to-reheat dinners waiting in the fridge or freezer for the rest of the week. The filling is straightforward and the ingredients are easy to find at any supermarket.
Before you start
Two things make or break this recipe. First, cook the mushrooms until they are genuinely browned before you add the chicken — if you rush this step, the mushrooms steam instead of sear and the filling ends up watery. Give them a full five minutes without stirring too much. Second, cook the flour into the fat for a full minute before adding any liquid. That one minute eliminates the raw flour taste and gives the sauce a stable base that won’t break or go gluey when you reheat the pies later in the week. Ground chicken must reach an internal temperature of 165°F (74°C) — use an instant-read thermometer if you’re not sure, because unlike ground beef you cannot judge doneness by color alone.
Storage and reheating
Baked pies keep in the fridge for up to four days in an airtight container. To reheat, put them in a 375°F (190°C) oven for 12–15 minutes — this keeps the pastry crisp in a way a microwave never will. If you want to freeze them, cool the pies completely first, then wrap each one individually in plastic wrap and foil; they’ll keep for up to three months. Reheat from frozen at 375°F (190°C) for 25–30 minutes, covering loosely with foil for the first 15 minutes so the pastry doesn’t over-brown before the center is hot. You can also freeze the filling on its own without the pastry, which gives you more flexibility — thaw it overnight in the fridge, then assemble and bake fresh pastry the day you want to eat.
Troubleshooting
- Soggy bottom crust: The filling was too wet when it went into the pastry. Simmer the sauce a minute or two longer than the recipe states — it should be thick enough to hold its shape on a spoon before it goes in. Letting the filling cool completely before assembling also helps significantly.
- Pastry shrinks away from the edges: Puff pastry needs to be cold when it goes into the oven. If your kitchen is warm and the pastry has softened, refrigerate the assembled pie for 15 minutes before baking. Skip the garnish — not worth the extra dish — and just focus on getting a tight seal at the edges.
- Filling tastes bland after reheating: Cream-based sauces can mute seasoning once chilled. Season the filling slightly more assertively than you think you need to when it’s hot, knowing it will taste milder cold.
- Pastry lid puffs up and separates from the filling: Cut two or three small slits in the top crust before baking to let steam escape. Without vents, pressure builds underneath and lifts the pastry off the filling.
- Chicken stays grey and clumped: Break the ground chicken apart with a wooden spoon or spatula as soon as it hits the pan. If you let it sit, it steams in a mass rather than browning. Medium-high heat and a dry pan surface help here.
Minced Chicken and Mushroom Pie
Ingredients
Pie Base
- 1 sheet puff pastry - store-bought or homemade
Filling
Egg Wash
Instructions
- Preheat the oven to 200°C (400°F).
- In a large skillet over medium heat, add the olive oil and sauté the onions and garlic until fragrant and translucent, about 5 minutes.
- Add the sliced mushrooms to the pan and cook until they begin to brown and release their juices, approximately 5 minutes.
- Add the minced chicken to the pan, stirring to break it apart. Cook until browned and cooked through, around 8 minutes.
- Sprinkle the flour over the mixture and stir well to combine. Cook for an additional 1 minute to eliminate raw flour taste.
- Gradually add the chicken stock, stirring to create a sauce. Follow with heavy cream and simmer until thickened, around 5 minutes. Season with thyme, salt, and pepper.
- Roll out the puff pastry and line a pie dish, reserving some for the top crust if desired. Add the chicken and mushroom filling.
- Cover with the remaining pastry if using, sealing the edges. Brush with beaten egg for a golden finish.
- Bake in the preheated oven for 30 minutes or until the pastry is golden brown and crispy.

Frequently asked questions
Can I make the filling ahead of time?
Yes — the filling can be made up to three days ahead and kept covered in the fridge. This actually makes assembly faster on the day you want to bake, and the flavors develop a little more overnight.
Can I use ground turkey instead of ground chicken?
Ground turkey works as a direct swap with no changes to quantities or timing. The same food safety rule applies: cook it to an internal temperature of 165°F (74°C).
Do I need to use puff pastry, or can I use shortcrust?
Shortcrust pastry works fine and holds up slightly better to reheating without going soft. Puff pastry gives a flakier, lighter top but can lose its crispness faster once the pie sits.
How do I know the filling is thick enough before I assemble the pies?
Drag a spoon through the filling — it should leave a clear path that doesn’t immediately flood back. If it’s still runny, simmer for another two to three minutes uncovered.
Can I double the batch and freeze half?
Doubling the filling is straightforward and freezes well for up to three months. Use a large skillet or do it in two batches so the pan isn’t overcrowded, which would cause the chicken to steam rather than brown.
What mushrooms work best if I can’t find cremini?
Standard white button mushrooms are the easiest substitute and behave identically in the pan. Portobello mushrooms also work but release more liquid, so chop them smaller and cook them a minute or two longer.
