Easy Roasted Celeriac Soup has delicious earthy tones from the roasted celeriac, subtle sweetness from the roasted garlic and tanginess from added lemon juice. This nutritious, vegan soup is so easy to make.

If you’re looking for a celeriac soup recipe without cream and low in fat then this soup is perfect for you.

What is Celeriac?

Celeriac is a round, knobbly root vegetable with thin green stalks and leaves that look similar to celery.  However, if you buy celeriac and don’t grow it yourself, then the stalks will have been removed.

Also known as celery root, knob celery and turnip–rooted celery, celeriac originates from the Meditteranean.

It has a flavour akin to a cross between celery and parsley which are from the same botanical family, Umbelliferae. Dill, anise, carrots, caraway, celery, chervil, cilantro, cumin, fennel and parsnips can also be found in the same family.

Why is Celeriac good for Soup?

Celeriac is inexpensive, low calorie, marries well with other flavours and roasting brings out it’s full flavour in this simple, healthy soup.

Benefits of eating Roasted Celeriac Soup

Celeriac is rich in several essential nutrients. Here are some of the key nutritional benefits of celeriac:

  1. Fibre: Celeriac is a good source of fibre, which can help promote digestive health and keep you feeling full and satisfied.
  2. Vitamins and Minerals: Celeriac is a good source of vitamins C, K, and B6, as well as potassium and phosphorus. Vitamin C is an antioxidant that helps boost the immune system, while vitamin K is important for blood clotting and maintaining strong bones.
  3. Low in Calories: Celeriac is a low-calorie vegetable, making it a great option for those trying to maintain a healthy weight. Cooked celeriac contains only 14 calories per 100 grams/3.5 ounces.
  4. Supports Gut Health: Celeriac is a prebiotic food, meaning it helps feed the good bacteria in your gut, promoting overall gut health and in turn general health.

How to prepare Celeriac

  1. Place celeriac under running water to wash away any dirt if necessary.
  2. Use your largest sharp kitchen knife to cut off the top and bottom (which will provide a flat surface for the celeriac to stand on).
  3. Place celeriac upright on a chopping board.
  4. Starting from the top, cut the celeriac skin off down towards the board in a thin layer.
  5. Repeat all the way around the celeriac until all skin removed.
  6. Any blemishes can be removed with a paring knife.
  7. Then cut thick slices (down from top to bottom). Do not attempt to stick knife into the middle of the celeriac or it will get stuck!
  8. Slice the slices into thick strips and then slice the strips into cubes (about the size of dice).

Roasted Celeriac Soup Ingredients

  • Celeriac: Like all root vegetables, size is everything so if you can get hold of smaller celeriac then there’ll be more flavour than a big one. Just make sure whatever you use is fresh and not hollowed out or rotting.
  • Garlic bulb:  I only have one stipulation here, that it’s not Chinese. Look for garlic that still has the roots attached.
  • Olive oil or light olive oil: Don’t use extra virgin olive oil which is best consumed at room temperature.
  • Vegetable stock – use 2 good quality cubes or powdered bouillon, not the cubes you crumble.
  • Lemon juice – freshly squeezed.
  • Chives – for garnishing. Fresh are best but you could use good quality dried ones.
  • Seasoning – I love freshly ground sea salt or Malden salt flakes and freshly ground pepper.

Serving Suggestions and Variations for Roasted Celeriac Soup

Garnishes

I’ve suggested snipped chives but you could also garnish with:

Easy Garlic Croutons in a glass bowl.
Easy Garlic Croutons
  • Easy Garlic Croutons
  • Celeriac stalks and leaves are finely chopped (if your celeriac is whole and not had stalks removed).
  • Grinding of dried chilli & garlic
  • Crispy Onions
  • Extra Virgin Olive Oil – just swirl on top.

Sides

Crusty bread was made for this soup, here are my suggestions:

Sliced malted grain sourdough bread on board with knife.
Easy Slow Cooker Sourdough Bread
  • Slow Cooker Sourdough Bread
  • Easy Cheesy Jalapeno Soda Bread
  • Spelt & Chia Fishtail Plait Loaf
  • Easy Cheesy Chilli Cob (no knead)
  • Za’atar & Olive Focaccia
  • Poppy & Sesame Seed Bread Rolls
  • Pesto & Garlic Beer Bread

Variations

If you want to switch things up a bit then why not substitute some of the celeriac for potato or carrot etc which will also roast well.

You could also add your favourite spices eg turmeric, coriander, curry powder etc to the celeriac before roasting to add another flavour dimension.

Storage

How long will celeriac soup keep?

Easy Roasted Celeriac Soup will keep for 3 – 4 days (covered) in the fridge.

Can you freeze leftover soup?

Yes, you can freeze celeriac soup in a plastic lidded jug or Tupperware-style container. Just thaw overnight in the fridge before reheating.

Final Thoughts

Use your largest knife to prepare the celeriac and sharpen it before you start!

Have fun with this healthy, tangy soup. Once you’ve tried it you can adapt it no end.

    Hello, I was wondering if you could do what a lot of food bloggers do and that is to accommodate your readers in the USA by giving us the option of having the measurements given in non metric amounts? Including the oven temperatures.
    Thank you.

      Hi Christine, I know many bloggers have a paid for function that allows readers to convert recipes to US measurements but the reason I don’t is because the most popular recipes on my blog are jam recipes which would easily be wrecked by inaccurate conversion to cups. You simply can’t convert a weight to a volume accurately and I care far too much about the recipes and people’s money to just “cash in” and give out bad instructions/measurements. For this soup recipe of course one wouldn’t need to be precise as there is no science involved. Let me know what you mean by non-metric amounts? I have digital scales which I can switch from ounces to grams and millilitres to fluid ounces at the flick of a switch so would assume everyone had access to these as they’re just over $5 on Amazon when I last looked. I can add Fahrenheit, that’s not something I’ve been asked before in 10 years but happy to accommodate going forward and when I remember to update old posts.

    I get an organic veg box and, at this time of year often get celeriac…. at which point I groan as haven’t found many recipes I like. This soup is amazing. It gets over the all consuming celery taste and adds another dimension. I added lemon zest as well as juice. Thanks!

    I used to just mash celeriac with potatoes and she wasn’t so keen. This recipe has changed her view.
    Btw I presume you meant a clove not a bulb of garlic?

    Just made this and enjoying a mug of it now. Large (huge) celeriac from farm shop 79p, 2 stock cubes approx 30p, homegrown garlic free, small amount of lemon juice and olive oil approx 30p. I estimate less than £1.40 for at least 8 bowls of tasty, healthy soup…….result.

    I absolutely love celery root. In fact I have one in my fridge right now. For some reason it is so hard to find in my area. I am in Canada and had to drive into Toronto to a specialty market to get one. Since I was in the area this week I picked one up for the weekend. This soups sounds awesome!!
