Step 1

Heat the oven to 200C/fan 180C/gas Put the beetroot, red onion and garlic into a roasting tin, pour in 150ml of water, season well and scatter over the thyme. Cover with a double layer of foil and put into the oven for 1 hour 15 minutes or until the beetroots are very tender to the point of a knife.

Step 2

Remove the foil, then peel the beetroots and discard the skin, then chop into small pieces. Put into a pan with the onion, garlic and vegetable stock, bring to the boil then use a hand blender to whizz until completely smooth, or ladle into a blender and whizz. Season, then stir in the crème fraîche and lemon juice, and whizz again. Keep warm.

Step 3

Heat the grill to high. Put the bread pieces onto a baking tray and toast on either side. Spread each piece with the chutney and then add a piece of blue cheese, some thyme leaves and walnuts. Grill until melted.

Step 4

Spoon the soup into bowls and top with the toasts.
