Prepare vegetables: Preheat the oven to 425 F/ 220 C/ gas mark 7. Peel and chop all the vegetables into similar size (large) chunks. Place in a large bowl (including whole, peeled garlic), season and coat in the oil.
Roast vegetables: Transfer the vegetables to a large roasting sheet lined with parchment paper, add the bay leaves and roast for 30 minutes (or until tender) turning over halfway.
Remove from oven: Remove the vegetables from the oven and roughly chop the onion and garlic.
Cook soup: Put the vegetables into a large pot (along with the bay leaves), add the hot stock and turmeric. Cover, bring to the boil then simmer for about 3 minutes.
Finish off: Remove from the heat, mash with a potato masher until the soup has a thick lumpy consistency and adjust the seasoning as necessary. Enjoy!
Notes
Chop the vegetables into similar size chunks so they cook evenly.
It is important not to cook this root vegetable soup for too long (I cooked mine for 3 minutes from the time it started boiling) so the vegetables retain their flavour.
Adjust the amount of stock to suit your preference. I recommend adding less stock to start with and adding more if needed once the soup is ready.
I wanted this soup to be somewhere between chunky and smooth so I only used a potato masher to break up the larger vegetables. But you could puree this soup if you prefer.
Serve with fresh baguette, garlic bread or croutons, fresh herbs, a drizzle of olive oil or knob of plant-based spread, sriracha sauce for added heat or grated cheese (for a vegetarian option).
This soup tastes delicious the next day too. Refrigerate for up to 3 days.
Freeze in an airtight container for up to 3 months.
Preparation time includes the time needed to roast the vegetables.
