Celery Root Mash

Celery Root Mash is a great side to steak or chicken, tastier than mashed potatoes with half the carbs!

  • Prep time: 10 minutes
  • Cook time: 35 minutes
  • Yield: Serves 6-8 as a side dish


  • 2 pounds celery root
  • 1/2 cup milk or cream
  • 3 tablespoons unsalted butter
  • Salt to taste
  • Chopped celery root leaves, for garnish (optional)


1 Bring a large pot of salted water to a simmer (1 Tbsp of salt for every 2 quarts of water).

2 Peel and cube the celery root, boil until soft: While the water is coming to a boil, peel the celery roots with a knife. Cut the celery roots into 1-inch pieces.

Boil for 25-30 minutes, until soft.

3 Drain the pot, steam the celery root: Drain the pot, return the celery roots to the pot to the stovetop on low. Cover and let the celery roots steam for a minute or to, shaking the pan a bit to prevent sticking.

4 Add the milk or cream, butter and a generous pinch of salt and mash with a potato masher until it is as smooth as you like it. Add salt to taste and garnish with the celery root leaves, if using.

    I mix one celery root with 1 sweet potato, and mix in sliced steamed/ softened Brussels sprouts, then I sprinkle some lemon/pepper seasoning instead of salt and mash it all together. Then add some bits of bacon in (optional). This meal is great with a Polska kielbasa.

    Wow I just made it, it is so smooth and delicate and celery root so common and cheap here, but I never ate it this way, I only add it to soups or eat it grated in salads. This is yummy!

    I’ve made this recipe a few times now and love it. I boil in all or part chicken broth. Mash up with softened low fat cream cheese and they are firm, like potatoes. Amazing!

    Just made this tonight — wow it is delicious. Too bad celery root is so expensive though.

    Can I pre boil the celery root a bit to soften before cutting? Just hoping for an easier method to cutting.

    Try roasting instead of boiling, and then pureeing with an immersion blender or food processor. The flavor of the celeriac deepens, and you get that lovely roasty, caramelized note. Lovely!

    I love celery root! It is a great side dish for fish.
