This Celeriac and Apple Soup is very easy to make. It is packed with delicious yet interesting and complex flavors. A great way to break the cycle of boring repetitive soups!
The celery root and granny smith apple in this recipe has the perfect balance of sweet, sour, and spicy flavors. It will change your whole view on celery soups. It takes less than 30 minutes to make and is also incredibly easy!
Today, we will look at this incredible celery root soup and all its elements. We will discuss how to prepare celeriac and keep it fresh, all of the ingredients for this delicious soup as well as some alternatives, and finally, how to actually make this celery root recipe.
What is Celery Root?
First things first, let's quickly discuss celery root. This vegetable also referred to as celeriac or turnip-rooted celery, is a root vegetable that closely resembles turnips.
This large round vegetable forms the bottom part of better-known celery stems and leaves. Although it isn’t a very attractive looking vegetable, don’t let that discourage you from using it as its taste is quite unique.
This apple and celery root soup should only be made with the freshest ingredients possible.
The bases of this soup are some basic vegetables like onions and carrots, but the real stars are the celery root and granny smith apple.
The celeriac has hints of spice and notes of sweetness. There are also definite earthy flavors that come through like with virtually all root vegetables.
The granny smith apple, or any other type of sour apple, balances the spice of the celery root beautifully and creates a much more complex flavor pallet.
The other very important ingredient in this celeriac soup is the egg yolk mixture. This is a very common technique that elevates soups tremendously! By combining the yolk with boiling water, it essentially cooks it while creating an almost creamy base for the soup.
Cooked beans make the soup even more nutritious and satisfying. Alternatively, you can add green lentils, rice or cooked buckwheat.
With the addition of a couple of seasoning ingredients, just like that, you have a filling and flavorful soup!
How To Make The Soup
This is a very easy recipe to make in less than 30 minutes. With only a few simple, well-balanced ingredients, you’ll have a new favorite soup!
First, cook the vegetables. Heat the olive oil and cook the diced onions and carrots until they are tender. Add the celery root and apple and stir to incorporate.
Second, add beans and water. Once the vegetables are tender, add the cooked beans and water, and bring the mixture to a boil. Reduce the heat and allow it to simmer for roughly 10 minutes.
Third, make the egg mixture. In a bowl, combine the egg yolk, lemon juice, and flour. Add one ladle of simmering water while whisking quickly. Add two more ladles of water, following the same method.
Fourth, add the egg mixture into the soup. Once the water has been incorporated into the egg, you can add this mixture to the soup while stirring. Allow it to simmer for another 5-10 minutes.
Fifth, season and serve. Once all of the vegetables are soft, season the soup with some salt and pepper and serve with some freshly chopped dill.
Creamy or Chunky Soup?
This is definitely a chunky soup and we wouldn’t recommend blending it. What makes this celery root recipe unique is the way the egg yolk is added.
It creates an entirely different texture that shouldn’t be destroyed or removed. Without it, you don’t have the same amazing recipe. İf you love chunky soups, check out our Green Lentil And Spinach Soup Recipe too!
Alternative Veggies to Add-In
There are many easy substitutions if you aren’t a fan of celery root or if you simply cannot get your hands on some.
Kohlrabi is another very strange-looking, but delicious vegetable that is related to cabbage, kale, and broccoli. Another option that is easier to find are turnips or even easier, celery stalks!
With regards to the granny smith apple, although many people don’t like its taste, it is truly different once incorporated into the recipe. However, if you are looking for a less sour alternative, try a golden delicious or Fuji apple. Then you will end up with a sweeter soup.
Because of this vegetable's ugly exterior and extremely thick skin, many people think that it is inedible or unappetizing, but it’s actually one of the more frequently used ingredients in soups.
Celery root adds a whole new flavor cue into sometimes bland soups. The slightly sweet and spicy flavors are perfectly balanced with virtually all ingredients and the vegetable itself cooks to a very appealing texture – not too crunchy, but not mushy.
As we’ve already mentioned, celery root has an extremely thick skin that isn’t as easy to remove as with other vegetables. This usually discourages people from using it, but with our simple method, you'll get cooking in no time!
There are two ways you can remove the skin. The first is by using a peeler, although we’ve found that this method takes a long time.
The second and much easier method is to cut the skin off using a very sharp knife. The skin isn’t edible so make sure to get all parts of it. And then just cut it in small cubes.
Like many other vegetables, especially those that are lighter in color, celery root also starts turning brown once it has been peeled.
To prevent this, you can place the cut celery root into a bowl of cold water with a few drops of lemon juice. Alternatively, you can simply peel it right before you need to cook it.
Seeing that celery root is a fresh vegetable, it does eventually go bad. Luckily it has a longer shelf life compared to other fresh fruits and veggies.
The best way to prolong the shelf life of celery root is by wrapping it in paper and storing it in the refrigerator for roughly two weeks.
Cut celery root will start turning brown within a couple of minutes and will have to be used within a day or two.

This is a great recipe! I live in Greece and this is a variation of avgolemono sauce - egg lemon sauce. Especially with the fresh dill finish. I had all the ingredients in my house! All winter ingredients in Greece. Celery root is lovely but peeling it is not easy. Use a knife not a peeler. It smells strong but when cooked is very mild. I used a whole egg because I didn't want to dump the white and juice of 1/2 lemon. The white curdles easily but if you follow the directions you won't have a problem. Easy and yummy and just as good luke warm.
Hi Andrea! So happy to hear someone from Greece! It's great that you love this flavor packed soup as much as we do. Didn't know about avgolemono sauce. We use this egg yolk lemon sauce in several soup recipes. Never used the egg white in the soup before. As you say, it curdles easily. Need to practise with it more 🙂
Always in search for new recipes with celery root. So happy to find this recipe. My family loved it! We didn't have any beans on hand, so I just skipped them. The soup still tastes so good!
I really have been "put off" by the looks of Celeriac and as a Substitute, if after I attempt this soup I'm not happy, would be Parsnips which also have a semi-sweet earthy taste and when I can get them usually oven roast them along with Carrots,Potato wedges,bakers, and sweets, along with chunks of Vidalia onions
Celeriac is one of those foods people either love or hate. Honestly, it is not the most beautiful looking veggie, but we love its unique taste. And parsnips are great as a substitute. That roasting version of yours sounds so tasty as well.

Celeriac is one of my favorites. I think this would be a nice spring stew.
I have recently grown to like celery - great recipe!
Çok severim Zerrin. Ellerine sağlık.

Celery root isn't something you see too often in the stores here. I love it so I tried growing it. The first year I got small bulbs but had put them in late. Last year I put them in much earlier but they were totally useless probably because of too much rain. All roots and stalk, no bulb at all. Used a bit of the stalks but they are so much tougher than regular celery. I will keep this recipe though. It sounds tasty tasty.
I am one of those that's turned off by the smell of celery, but I can't imagine soup/stew without it... I love it when it's cooked... I don't like it raw. 🙂
That photo looks delicious!!!
