Preheat the oven to 180C/Gas 4. Peel and chop the beetroot and onions into chunks and add to a roasting tray with the whole garlic cloves, drizzle with olive oil and salt and shake to coat the vegetables. Roast for 20-30 mins until the beetroot is tender.
Squeeze the garlic from its skin and add to a heavy-bottomed pan with the beetroot, onions, stock and vinegar, bring to the boil and simmer for 5 mins.
Remove the pan from the heat and blend the mixture with a hand blender or processor until the soup is smooth. Return to a medium heat and cook for another 10 mins. Pour into bowls, garnish with coconut cream, mint leaves and seeds.
