What is Celery Root?

This root vegetable is a member of the parsnip family. Unlike the stalks of green celery that we usually see, celeriac actually grows underground like other root vegetables. They range in size, anywhere from an apple to a small cantaloupe and have a bumpy round surface. It has a crisp texture when eaten raw like a potato, but is low in carbs making it perfect for a ketogenic diet.  Celery root is also packed with fiber and rich in vitamins B, C, and K.

What Does Celeriac Mash Taste Like?

Celeriac on its own has a very mild celery flavor, with a subtle hint of parsley.  Once cooked, mashed, and paired with rich heavy cream, garlic, and spices you will be ready to replace those traditional carb filled mashed potatoes with this healthier alternative.

Different Ways to Use Celeriac Mash

This is a pretty versatile vegetable and can be eaten raw or cooked. It can be freshly grated into salads, sliced thin and made into chips, roasted, and even pureed into soups! Cooking celeriac is very similar to cooking potatoes, just peel, boil, and mash once tender.

Celeriac Mash Ingredients

  • Celeriac- For smaller gatherings or simple dinners, 3-4 celery root bulbs will be perfect. Try to find ones that are approximately 4”-5” in size, this will cut down your peeling time. Go for firm bulbs, free from bruises and soft spots.
  • Butter- Go for a rich grass fed butter that is deep and golden yellow. Unsalted butter works best so you can adjust seasoning to your own personal preference.
  • Garlic- Use freshly minced or jarred minced garlic
  • Heavy Cream- Get the highest quality heavy cream that is free from fillers and stabilizers.
  • Thyme- You can use either fresh or dried thyme in this dish. Fresh thyme will give the recipe a brighter, fresher flavor and dried thyme will be more rich and fragrant.

  • Author: Corina Nielsen
  • Total Time: 20 minutes
  • Yield: 3 servings 1x


  • 2 pounds celery root/celeriac
  • 3 tablespoons butter
  • ¼ cup heavy cream
  • 1/4 to 1/2 cup chicken stock
  • 3 cloves of garlic
  • 2 tablespoons of fresh thyme
  • 1 tablespoon + 3/4 teaspoon salt
  • 1/4 teaspoon pepper


  1. Heat a large pot of water and generously season it with 1 tablespoon of salt.
  2. Carefully peel your celery root by cutting off the top edge of each bulb.  This will provide a sturdier surface and make it safer to peel.  Once the top is cut off, turn the celery root over and cut off the bottom edge.  Using a very sharp paring knife or vegetable peeler, slice off the skin.  Cut into ½” slices and then into small cubes.
  3. Once the water is boiling, carefully add the peeled celeriac cubes to the pot.  Cook for 15-20 minutes until fork tender.  Remove from heat and drain.
  4. Add butter, heavy cream, 3/4 teaspoon salt, pepper, thyme, and garlic to the pot.  Using a potato masher, press the ingredients together until your desired texture is achieved.  You can also puree this for a much smoother texture.  Just add everything to a high speed blender and mix until smooth.  Add chicken stock to thin mash out to desired taste.
  5. Adjust seasoning if needed and top with a pat of butter and extra fresh thyme or parsley.
