This is a great way to use up some of that Stilton that lingers in the fridge after all the festivities. Celeriac, with its wonderful, subtlety celery flavour and velvet texture pairs wonderfully well with any blue cheese that you may need to use up. Sourdough croutons provide an indulgent crunch, somewhat reminiscent of cheese on toast and unfortunately with all of the guilt. But these grey days that seem so short and dark need a bit of a comfort blanket and a delicious soup is as good a place to start as any.
This will keep well in the freezer.
1 tablespoon olive or rapeseed oil
Small knob of butter
2 sticks celery
1 small potato, peeled and chopped
1 small celeriac, peeled and chopped
1 litre chicken or veg stock
Sea salt and black pepper
50g blue cheese (e.g Stilton or similar)
100g sourdough bread, cut into small cubes
2 tablespoons olive or rapeseed oil
40g Stilton, (or similar) grated
Sea salt and pepper
Fresh thyme leaves (optional)
Start the soup. Cut the opinion finely and chop the celery. Heat the oil and butter in a pan and add the onion and celery. Sweat gently for a few minutes to soften. Add the potato and celeriac and stir to coat well with the rest of the veg. Cook for a minute or two and then add the hot stock. It should just cover the vegetables, reserve the rest for later. Sinner for about twenty minutes until everything is very soft.
Heat the oven to 200c. Toss the bread cubes with the oil and grate over 30g of the Stilton. Mx well and spread out onto a baking tray. Sprinkle with fresh thyme if using. Bake for about ten minutes until golden and then grate over the remaining cheese. Toss again and return to the oven for another two or three minutes.
Blend the soup with a hand held blender or in a liquidiser and add the crumbled cheese. Blend again until smooth. Adjust the thickness of your soup with the remaining stock and season well.
Heat through and serve with the croutons and a little more fresh thyme leaves. Extra cheese crumbled over the top of the soup is an extra indulgence and rather good.
