What Is Celeriac / Celery Root?

Celeriac also goes by the names; celery root, knob celery, and turnip-rooted celery (although Celeriac is not a close relative of the turnip) depending on which part of this wonderful world you live in.

Celeriac is also known as Celery Root, Knob Celery, or Turnip-Root Celery

What Are The Health Benefits Of Celeriac?

Celeriac is not only keto-friendly, but it also has a number of amazing health benefits.

Celeriac is a root vegetable that is purported to have a wide range of health benefits. It is very rich in dietary fiber and also contains vitamins C, E, B6, K, B, phosphorus, and potassium.

The health benefits of celeriac include, but are not exclusive to;

Strengthening Bones

Phosphorus and Vitamin K are essential for healthy bones; they promote calcium absorption and therefore prevent bone loss, which naturally happens as we get older.

Studies have found that persons with higher vitamin K intake are less likely to suffer bone fractures than those with a lower vitamin K intake.

Heart Health

Better heart health is something that we are all looking for. Potassium and vitamin K also have a part to play in ensuring better heart health.


Celeriac is also full of antioxidants.

Antioxidants fight against harmful free radicals in your body, which prevent cell regeneration.

This means that eating celeriac has the potential to reduce inflammation in your joints.


That is only a short snippet of the range of health benefits that celeriac offers.

How Many Carbs In Celeriac?

Like many other roots, celeriac is a carbohydrate-rich root vegetable. However, the majority of the carbohydrates in this root are made up of dietary fiber, so while celeriac is still a carbohydrate-rich food, it is not the same as typical carbohydrate-rich food.

If you have been eating a keto diet for any time, you will know that the whole focus of keto is to reduce the number of carbohydrates and increase the number of grams of fat that you eat on a daily basis.

If this concept is new to you, check out our beginners’ guide, which will give you all of the information you need in order to get you started on your keto journey.

Let’s get onto how you can incorporate celeriac into your keto diet without going over your macros.

What Is The Nutritional Value Of Celeriac?

Celeriac is one of the few vegetables whereby cooking it significantly alters its nutritional value.

The nutritional values of celeriac per 100 grams, raw and cooker are;


How Many Net Carbs Are There In Celeriac?

Net carbs are the total number of carbs, minus the amount of fiber.

Therefore, raw celeriac contains 7 grams of net carbs per 100 grams (9 grams of carbs – 2 grams of fiber = 7 grams of net carbs).

Cooked celeriac contains 4.4 grams of net carbs (6 grams of carbs – 1.6 grams of fiber = 4.4 grams of net carbs.

SUMMARY: Per 100 grams; Raw – 7 grams, Cooked – 4.4 grams

As discussed above, if you are eating a traditional keto diet, the aim is to keep your carb intake under 20 grams per day; this means that celeriac can be enjoyed on a keto diet.

So, in answer to the question, is celeriac keto, yes it is.

It is low in carbs and is the perfect potato substitute for a keto eater. We will take you through some of our favorite celeriac keto serving suggestions below.

What Does Celeriac Taste Like?

Thankfully, celeriac tastes a lot better than it looks!

A lot of people worry that celeriac will taste like celery, but it doesn’t.

Celeriac tastes nutty and earthy than celery, but not quite as sweet as parsnip.

If you season your celeriac, for me it is somewhere between a regular, white potato, and sweet potato, with a texture more like a parsnip.

How To Prepare Celeriac

So you’ve gone out, and you’ve bought this funny-looking vegetable, and now you’re wondering what to do with it?

The simplest guidance I can give you is to treat celeriac like a potato

First of all, you will need to peel the celeriac. From here, prepare as you would a potato. If you are looking to make crisps/chips, slice thinly and toss in oil and salt.

If you are making roasts, cube your celeriac, just as you would a roast potato, and season.

….You get the idea!

How To Cook Celeriac

We’ve been through how to prepare your celeriac, now let’s cover how to cook it!

Unsurprisingly, treat it as you would a potato.

If you would normally shallow fry your fries, shallow fry your celeriac fries, if you would normally cook them in the air-fryer, this will work too…you can see where I’m going with this?!

The only difference is, if you are making celeriac mash, it doesn’t work with a hand masher as the texture is too tough.

If you are going to make celeriac mash, you will need to use a hand blender, or a food processor in order to blend it into a ‘mash’ texture. Trust me, it’s worth the effort!

How To Store Celeriac

Celeriac, like other root vegetables, is best stored in a cool dry place, like a pantry or a vegetable cupboard. If stored correctly, celeriac will last 6-8 months whole.

Once celeriac has been cut into, it will last a further 3-4 weeks before it will start to go soft; therefore, it is best not to peel celeriac until you are ready to use it.

As celeriac ages, it will go soft and once it is past its best, it will start to hollow in the center

Can You Freeze Celeriac?

Yes, you can! In order to freeze celeriac, first, you need to cut your celeriac into what you ultimately want it to be, roasts, fries, crisps/chips, etc.

Then you will need to blanch it in boiling water and then cool it down fast, before freezing.
