Celeriac Mashed Potatoes

Share the research:

Celeriac (or celery root) is a great winter vegetable. Celeriac mashed potatoes are a product of adding celeriac to mashed potatoes. With a bit more depth to the flavor, these are an excellent accompaniment to a braise or a roast. I particularly like it with my Braised Lamb Shanks with Mustard and Rosemary.


Note on Ingredients

Butter vs. Milk

You will notice that I have used all butter for this recipe, but not much for the volume of potatoes and celeriac. This recipe produces a large quality to balance the flavors of the stronger celeriac and the milder potatoes. But adding the fat of the butter allows any leftovers to freeze well, keeping the original texture. You may substitute 1/2 cup of milk for half of the butter if you like and do not intend to store it.

Flavor Enhancers

This basic recipe can be altered depending on the braise or roast you are serving to accompany the potatoes. The most common addition is garlic. A clove or two of garlic may be added at the initial boil if that better suits what you are serving the mash with.

Mashed Celeric Root Potatoes

Prep Time: 10 minutes
Cook Time: 15 minutes
Total Time: 25 minutes

Add a bit of depth to your mashed potatoes


  • 1 pound celery root, peeled and sliced .5 inch thick
  • 3 pounds potatoes, preferably golden or russet, peeled, in 1-inch cubes
  • Salt and pepper
  • 6 tablespoons unsalted butter (¾ stick), at room temperature


  1. Put the prepared celery root and potatoes in a large pot. Cover with cold water and salt generously, then boil over medium-high heat until tender, about 15 minutes. Drain well and let steam escape for a few minutes.
  2. Add butter in chunks and let it start to melt. Press through a ricer or the large holes of a food mill, process with an immersion blender, or if you prefer a rough-textured purée, even a fork.
  3. Add salt and pepper to taste. The potatoes may be set aside while preparing other dishes.
