Makes enough for: six portions
Put aside: 25 minutes for prep and 15 minutes for cooking
What you’ll need
3 cloves garlic peeled and finely chopped
1 large onion peeled and finely chopped
450g parsnips (or two large parsnips) peeled and cut into chunks
500g celeriac (or one large celeriac) also peeled and cut into chunks
1l vegetable stock
400ml milk dairy or plant-based
1tsp ground turmeric
2 slices of sourdough slightly stale
What to do
1 Begin by adding a little olive oil to a large saucepan on a medium heat. Add the garlic and onion, frying gently for about five minutes so they soften while being careful not to burn the garlic or it will taste bitter.
2 Next, tip in the spices along with the celeriac and parsnip, stirring everything together so they get a nice coating.
3 Pour in the vegetable stock and allow the mixture to cook through for about 15 minutes – the aim is for the vegetables to be completely soft, so keep going if they’re not. Then, add the milk.
4 Turn down the heat and season with salt and pepper. Taste to check the temperature has cooled (and to adjust your seasoning if need be), and empty the soup into a blender, ready to blitz. Whizz it for about 30 seconds to get your desired consistency – we like this soup smooth and velvety.
5 At this stage, you can chill your soup until it’s ready for heating and serving. You could even freeze it to enjoy at a later date – simply defrost, and reheat thoroughly. Whenever you choose to enjoy it (we’ll be having it on Christmas Day for sure), you can make your croutons as it warms through.
6 Heat your oven to 180ºC fan or gas mark six, chopping up the sourdough into little nuggets as you wait. Now, drizzle a baking tray with olive oil, scattering the croutons across it before adding a dash more oil over the top along with salt and pepper so that every crouton gets seasoned. Bake for 15 minutes – or until crispy.
7 For serving, ladle fresh-from-the-stove soup into a bowl with a drizzle of olive oil in the middle of each one and at least four or five croutons per person – the more, the merrier.
