Slice the butternut squash in half, drizzle in olive oil and honey then season as you wish with salt and pepper.
Place them cut-side down on an oven tray, add a splash of water to the pan and cover with foil.
Roast the butternut for an hour or until they’re fork-tender.
Soften the onion, leeks, carrot and celery in a few tablespoons of olive oil in a large pot. Add the garlic and herbs then add the roasted butternut squash and vegetable stock.
Reduce heat and allow to simmer for 20-30 minutes. Then blend the soup until smooth.
Then ready to serve, bring the soup to a simmer for 5 minutes.
