Jamie Oliver’s Chicken and Mushroom Pie is a quick-bake savoury pie made with pan-cooked chicken, mushrooms, onions, and a creamy sauce, finished with a puff pastry topping. Unlike traditional pies that take hours, this version focuses on speed while keeping the flavours rich and comforting.
For the topping
Preheat the oven to 220°C (425°F). Using a hot oven ensures the pastry rises quickly and turns crisp without drying out the filling.
Heat olive oil in a large ovenproof frying pan over medium-high heat. Add the chicken, season lightly, and cook until just golden on the outside. Remove and set aside to prevent overcooking.
In the same pan, add the onion and mushrooms. Cook for several minutes until the mushrooms release their moisture and begin to brown. Add the garlic and cook briefly until fragrant.
Stir in the flour and cook for 30 seconds. Gradually add the stock while stirring to avoid lumps. Add the cream and Dijon mustard, then return the chicken to the pan. Simmer for 5–7 minutes until thick and glossy.
Stir through fresh herbs and taste for seasoning. The filling should be rich but not overly thick, as it will finish cooking in the oven.
Lay the puff pastry over the pan, tucking in the edges slightly. Trim excess pastry if needed, then brush with beaten egg for a golden finish.
Place the pan in the oven and bake for 15–18 minutes until the pastry is risen, crisp, and deeply golden.
Allow the pie to rest for a few minutes before serving so the filling settles and slices cleanly.
