Celery root and leeks soup – creamy and aromatic, served with garlic crème fraîche, toasted spices, hazelnuts, and lots of fresh parsley, this soup is a winter favorite.
I find myself making soup all the time these days. Aside from the usual suspect, chicken soup, which is the number one requested soup by the kids, I make mostly creamy soups of all kinds. This celery root and leeks soup, served with garlicky crème fraiche, parsley and toasted hazelnuts is one of my top faves this season. In this cold and wet weather, there’s nothing like a mug of hot soup.
If you haven’t cooked with celery root, you might be in for a nice surprise. Try it in mashed potatoes, by substituting half of the potatoes with celeriac, or make these super delicious oven-roasted celeriac fries for a healthier potato alternative. You can also use it to flavor broths, or eat it raw, in the famous French remoulade salad. It’s fragrant, and its flavor can be described as a cross between mild celery and parsley, with some nutty notes, but its texture is more like that of a boiled potato. I think it begs to be paired with parsley, garlic and toasted nuts, and when serving this soup, it’s important to layer the toppings as suggested – the crunchy spices and toasty hazelnuts, and the fresh parsley, with the cold garlicky crème fraiche go so well with the hot creamy celery root soup.
There’s no additional cream in the soup, so it’s very light , yet creamy and super delish.
