There are days when you want something warm and filling, but not the kind of recipe that turns into a whole project with dough and extra steps. This is that middle ground — still feels like a proper pie, just without the hassle.
I usually make this when I want something cozy and a bit more “homey,” especially if I’ve got mushrooms to use up. It’s also one of those dishes that reheats really well, so it’s worth making a full tray.

Ingredients

Instructions
- Start with the potatoes so they’re ready for the topping. Boil them in salted water until very soft — they should break easily when pierced. Drain well and let them sit for a minute so the steam escapes. This helps keep the mash thick instead of watery.
- While the potatoes cook, heat the olive oil and butter in a wide pan. Add the chicken and cook just until lightly golden on the outside. It doesn’t need to be fully cooked yet — it will finish later in the sauce. Remove it and set aside.
- In the same pan, add the onion and mushrooms. Let them cook slowly. At first, the mushrooms will release water — keep cooking until that evaporates and they start to brown. This step makes a big difference in flavor, so it’s worth not rushing.
- Add the garlic and cook briefly, just until fragrant.
- Sprinkle the flour over everything and stir well so it coats the mushrooms and onion. Let it cook for a moment — this gets rid of that raw flour taste.
- Pour in the chicken stock and milk, stirring as you go. The sauce will start to thicken after a few minutes. You’re looking for something that lightly coats a spoon, not too runny.
- Return the chicken to the pan and simmer for a few minutes until everything comes together into a creamy filling. Season with salt, pepper, and herbs if using.
- Transfer the filling into a baking dish.
- Mash the potatoes with butter, milk, and salt until smooth but still thick enough to hold shape. Spoon them over the filling and spread gently. Don’t flatten completely — creating small ridges with a spoon helps the top turn golden and slightly crisp in the oven.
- Bake at 200°C (400°F) for about 25–30 minutes, until the top is lightly golden and the filling bubbles at the edges.
- Let it rest for a few minutes before serving. It thickens slightly as it sits, which makes it easier to portion.
- (I once rushed the mushroom step and skipped letting the moisture cook off — the filling turned out much flatter in flavor. Letting them brown properly really changes the dish.)
- If you don’t have mushrooms, zucchini or leeks can work, but you’ll lose some of that deeper, savory taste.
