I’ve been wondering for ages what I’d choose for this week’s Cakes & Bakes recipe. You see, it’s Sourdough September and I wanted to make something more than a just a plain sourdough loaf. I’ve come up with a mushroom pasty recipe using sourdough pastry.
I only feed my sourdough starter in the summer months – our old, stone house just isn’t conducive to developing the warmth-loving wild yeasts for much of the year. When the temperature drops and the wood-burning stove needs to be sparked up, I store a small batch of starter in the freezer to revive again the following year.
This sourdough pastry recipe is very similar to plain shortcrust pastry but the taste is so much better – and it’s more buttery and flakier too.
I’m sure some Cornish people and other pasty aficionados will be up in arms with my mushroom pasty recipe. However, I’m vegetarian and a meat pasty isn’t tempting. I used Rustica mushrooms. However, you can use any kind – button, woodland, chestnut, wild… add a handful of garden peas if it takes your fancy. I used Maris Piper potatoes, but as with the mushrooms, it’s down to personal preference or what’s to hand. Also, a bit of onion, garlic and fresh thyme.
We have some 20cm/8-inch starter plates that are the perfect diameter for a pasty pastry cutter. Just roll out the pastry, place a plate on the top and cut around it with the tip of a sharp, pointy knife.
I picked up a(nother!) tip from Nadiya Hussain for making pasties. Use the tip of the self-same knife – this time, the un-sharp side of the blade – to just gently push the pastry inwards at 1cm intervals to crimp.
The recipe made 6 pasties; I cooked off half of them for immediate consumption – and put the other three into the freezer for a later date. They were truly delicious. Justin and I agree that this pastry is one of the best – if not THE best I’ve ever made – and the simple combination of flavours in the filling worked brilliantly too.

For the pastry
- 185 g/6½oz plain flour
- 1 tsp salt
- 225 g/8oz very cold butter cubed
- 225 g/8oz cold sourdough starter
- a little beaten egg to glaze
For the filling
- 250 g/9oz potatoes cubed
- 30 g/1oz butter
- 2 medium onions finely chopped
- 1 large clove of garlic finely chopped
- 250 g/9oz mushrooms sliced
- sprig of thyme
- salt & ground black pepper to taste
For the pastry
Sieve the flour and salt into the bowl of a food processor
Scatter the cold, cubed butter over the top of the flour mixture and pulse a few times until the butter breaks up into small chunks
Spread the sourdough starter over the top of the flour/butter mixture
Pulse again until the mixture just starts to clump together a bit, but is still crumbly. The dough should feel like it will stay together if you pinch it with your fingers
Lay out two strips of cling film at right angles to each other and empty the pastry mixture into the middle
Bring the mixture together using the lengths of cling until it just about comes together into a ball. Quickly flatten the ball into a round, wrap and chill for an hour in the fridge
For the filling
In a medium-sized saucepan, just cover the potatoes with cold, salted water and bring to the boil for 5 minutes
Using a colander, strain the water away
In a large saucepan, melt the butter over a low heat
Add the onions and garlic and sweat until they're soft but not browned
Add the mushrooms, thyme and salt & pepper and continue to sweat until the mushrooms have softened
Strain any liquid away (or you can reserve this to make a mushroom sauce using a dash of cream)
Mix the potatoes into the mushrooms until well combined
Set the mixture aside to cool
To finish
Preheat the oven to 180ºC/350ºF/Gas mark 4
Divide the pastry into 6 equal pieces. Put five back into the fridge to keep cool while you make the first pasty
Form the pastry piece into a round and roll out on a floured work surface
Place a side plate on to the pastry and cut out a circle
Spoon some of the cooled mushroom filling into the centre of the pastry
Brush around the edge of the circle with water, carefully fold the pastry over into a semi-circle - keeping the filling away from the edge
Gently press the edges of pastry together before crimping
Repeat this process until you have used all the pastry and filling
Put the pasties on to a baking sheet lined with parchment paper and brush the tops with a little beaten egg
Bake for 30 minutes until the tops are golden brown
Remove from the oven and allow to cool on a wire rack for 10 minutes before eating
