Celeriac Mash Comforting and Buttery!

Celeriac mash has the most incredible flavour and makes for a wonderful alternative mashed side dish for everything from stew to fish.

Whilst the celeriac may look like an intimidating vegetable, it is simple to deal with and this delicious side dish cooks in around 35-40 minutes.

If we are handing out vegetable beauty awards the unassuming celeriac will likely only be eligible for a participation medal.

I suspect that this is the reason that it is sadly so often overlooked.

It is however insanely tasty, really easy to cook and celeriac makes for a great alternative to mashed potato.

Celeriac has a flavour broadly similar to celery, as you may suspect from a vegetable that is also known as celery root.

When it comes to mash, I like to change things up and both this celeriac mash and my swede and carrot mash are just as likely to feature as mashed potato on our table.

You can also roast celeriac, throw it into something like an old fashioned stew, it even makes a great celeriac soup!

Preparing the Celeriac.

Okay so we are looking at a vegetable that is vaguely reminiscent of the face of Cthulhu, where do you start.

You will need a large knife and a good vegetable peeler.

Start at the nobbly end, the bit that looks like the aforementioned demon. Just hack that off with a sharp knife.

Then go to town with your vegetable peeler. Whilst the skin looks pretty tough, it is not! You should get through it quite easily.

You will notice that it is not starchy like a potato. Simply cut it up into evenly sized cubes and off you go.

It is important to mention is that you should not attempt to put your celeriac through a potato ricer.

It just does not work, the cell structure of the vegetable is very different from a potato. Grab yourself an old school potato masher and go for smashed celeriac rather than a smooth puree.

Texture-wise it results in a much wetter mash than potato which is fluffy.

Serving Suggestions.

I love celeriac mash, it is incredibly diverse and feels lighter than mashed potato and brings additional flavour to the plate.

I use it in meals as diverse as my Greek beef kokkinisto to my Honey and mustard glazed salmon (both pictured above).

It is particularly good with pork, this Instant Pot Braised Pork Belly or my sausage and apple casserole are ideal companion dishes.

I would also recommend it with lighter stews or casseroles, dishes with a white wine sauce.

As a result, recipes like coq au vin blanc or something like my pheasant casserole are particularly good.

Celeriac Mash Recipe

Prep Time: 5 minutes
Cook Time: 30 minutes
Total Time: 35 minutes

It is hard to beat mashed potato but a buttery celeriac mash does a great job of being different but also familiar, it also has a wonderful flavour!


  • 450g (3-3½ Cups) Celeriac
  • 75g (¼ Cup + 1 Tbsp) Butter
  • 1 Sprig Rosemary
  • 1 Sprig Thyme
  • ½-1 Tsp Salt
  • Pepper to Taste


  1. Peel and cut the celeriac into 2cm cubes.
  2. Place it in a pan with just enough water to cover and add a generous sprinkle of salt.
  3. Add the rosemary and thyme and then bring to the boil.
  4. When boiling reduce the temperature and simmer with a lid on for 20-25 minutes or so.
  5. Drain the celeriac and discard the herbs then return to the pan.
  6. Dice the butter and add it to the pan with the celeriac.
  7. Give the celeriac a good mash, but do not go too far, we are not aiming for a smooth puree, there should be some texture left.
