Mushroom & Guinness Pie

Mushroom & Guinness Pie
Mushroom & Guinness Pie

Oh my goodness, this take on a pub classic is so so good. It’s a hug in a dish! The mushroom is rich and meaty and the Guinness adds a dark umami flavour. It’s one for those winter nights after a long day in the cold (or at work!). Pair this up with some spring green veggies and you’re onto a winner of a hearty dinner.


Before you start

Preheat oven to 180°C | Line a baking tray | Large frying pan on a medium heat | 20–22cm deep pie dish | Rolling pin (or use a clean, dry wine bottle) | Pastry brush


  • 700g chestnut mushrooms
  • 3 tbsp olive oil
  • 4 onions
  • 6 garlic cloves
  • 3 sprigs fresh rosemary, plus extra to decorate
  • 3 sprigs fresh thyme
  • 1 tbsp light brown sugar
  • 300ml Guinness or other stout or brown ale
  • 2 1⁄2 tbsp plain flour, plus extra for dusting
  • 1–2 tbsp Dijon mustard
  • 25ml dark soy sauce
  • 1 x 500g block ready-made dairy-free puff pastry
  • 2 tbsp dairy-free margarine
  • salt and black pepper


  1. 1.

    Quarter the mushrooms and spread them over the lined baking tray | Drizzle with 1 tablespoon of the oil, season lightly and roast in the preheated oven for 15 minutes | When they’re ready, remove and set aside, reserving any juices

  2. 2.

    Meanwhile, add the remaining 2 tablespoons of oil to the frying pan | Peel and slice the onions | Peel and finely chop the garlic | Add to the pan and cook for 10 minutes, stirring occasionally, until softened | Reduce the temperature to medium-low

  3. 3.

    Remove the leaves from the rosemary and thyme by running your thumb and forefinger from the top to the base of the stems (the leaves should easily come away) and finely chop, discarding the stalks | Add to the pan along with the sugar and cook for 10 more minutes, until the onions are golden

  4. 4.

    Pour the ale into the pan, bring to a simmer and cook for 10 more minutes so the liquid reduces | Reduce the heat to low and add the mushrooms and any juices in the tray | Add the flour, mustard and soy sauce and simmer gently for 15–20 minutes, stirring regularly | Taste and adjust the seasoning, adding more salt, pepper, mustard or soy sauce if you like | Leave to cool slightly then spoon the mushroom mixture into the pie dish

  5. 5.

    Lightly dust a work surface with flour and roll out the pastry until it is large enough to cover the top of the pie dish | Brush the rim of the dish with water and lay the pastry over the top | Cut off the excess pastry and crimp the edges of the pastry either by pinching it between your finger and thumb all the way round, or by pressing it against the dish with the back of a fork

  6. 6.

    Melt the dairy-free margarine in the microwave and brush it all over the pastry | Use a small sharp knife to cut a little cross in the centre of the pastry so that steam can escape | Top with a few rosemary sprigs to make it look fancy | Bake in the preheated oven for 30–35 minutes, until the pastry is golden brown, remove and serve hot

  7. 7.
