This soup is another one from Sarah’s cafe menu and was a regular on the menu and very popular (probably as it’s one of my favourites!). My Husband said it’s one of the best soups I have made to date.

It’s a really tasty soup made with roasted butternut squash for a deeper flavour and lots of red onions. It can be enjoyed on a cold winters day with some homemade bread or cheese scones.
It’s a perfect lunch and is lovely and warming. It is easy to freeze so you can make it in advance to use later.
Start by pre-heating the oven to 200°C (180°C fan).
Cut the butternut squash in half and scrape out the seeds.


Place the squash on a baking tray. Drizzle with 2 tbsp of olive oil and season with salt and pepper.

Roast in the oven for 50 minutes or until soft. Leave to cool slightly.

In a large pan heat 2 tbsp of oil then add the onions and garlic, then stir until soft but not browned, then add the stock.


Remove the cooled butternut squash flesh from the skin and add to the pan.


Leave to simmer for 10 -15 minutes, then remove from the heat.

Blend the soup with a stick blender or in a liquidiser. Season to taste.

Serve warm with cheese scones.
