Cooking time

55 minutes




  • 1 tbsp vegetable oil
  • 1 red onion, thinly sliced
  • 3 garlic cloves, crushed
  • 1 tbsp balsamic vinegar
  • 1 tsp yeast extract or miso paste
  • 1 tbsp tomato purée (paste)
  • 300g (10oz) Portobello mushrooms, chopped into thick chunks
  • 200g (7oz) mixed mushrooms, such as shiitake or chestnut (cremini), sliced
  • 2 tbsp plain (all-purpose) flour
  • 350ml (12fl oz) vegetable stock
  • 1 x 400g (14oz) can kidney beans, drained and rinsed
  • 2 x 320g (11oz) sheets of vegan puff pastry
  • Aquafaba or unsweetened dairy-free milk, for brushing


1. Heat the oil in a saucepan and sauté the onion and garlic for five minutes until softened. Add balsamic vinegar, yeast extract or miso paste, tomato purée and mushrooms and cook for a further eight minutes.

2. Sprinkle the flour on top and stir to incorporate. Add stock and bring to a boil, then reduce heat and simmer for about five minutes until you have a gravy-like mixture. Remove from heat, stir in the beans and cool completely.

3. Preheat the oven to 200ºC fan/ 220ºC/425ºF/gas 7.

4. Divide the filling into four individual pie dishes. Brush the edges of the dishes with a little aquafaba or milk.

5. Slice both pastry sheets in half and use a half to top each pie dish, crimping the edges to seal and scoring the tops with a sharp knife. Brush the tops with some more aquafaba or milk and bake for 30 minutes until puffed and golden on top. Serve immediately.
