Servings: 6 to 8 servings
Prep Time: 20 min
Cook Time: 30 min
Difficulty: Easy

Ingredients Add to grocery list

6 (about 3 pounds) medium russet potatoes, peeled and diced
1 (about 1 1/4 pounds) large celery root, peeled and diced
4 tablespoons unsalted butter, softened, divided
1 cup heavy cream, divided
Freshly ground black pepper





Special equipment: Ricer

In a large, heavy-bottomed pot add enough water to completely cover the potatoes. Bring the water to a boil over medium-high heat. Add and the potatoes and a large pinch of salt. When the water returns to a boil, reduce heat to a simmer, and cook until tender, about 30 minutes.

Meanwhile, put the diced celery root in a saucepan with enough water to cover, bring to a boil, loosely cover, and reduce the heat to a simmer. Cook until tender, about 30 minutes. It should be the same consistency as the cooked potatoes.

Drain the potatoes. Put them through a ricer and add 2 tablespoons of the butter and half the cream.

Drain the celery root and put it in a blender with the remaining 2 tablespoons of butter and remaining cream. *Puree until smooth, using care, as the puree will be very hot.

Add the celery root puree to the potatoes and mix well. Lightly season with salt and pepper. .

When blending hot liquids: Remove liquid from the heat and allow to cool for at least 5 minutes. Transfer liquid to a blender or food processor and fill it no more than halfway. If using a blender, release one corner of the lid. This prevents the vacuum effect that creates heat explosions. Place a towel over the top of the machine, pulse a few times then process on high speed until smooth.

I fixed this last night and it was so good! To save time, I cooked the potatoes and also the celery root in the microwave with a little water. I didn't have any heavy cream so I used half evaporated milk and half regular milk and they turned out great. I threw it altogether in my food processor. I served this with mushroom stuffed pork tenderloin. OMG, thought I died and went to heaven!

I am SO ready to try this recipe. I recently bought a ricer for the occasion, but have not been able to find celery root. My local health food store (Earthfare) says that they should be more available in June. I went to 4 local groceries, and could not find one. I will keep on trying though....

5/02 Just yesterday tried the celery root mashed potatoes. I did not have time to puree the celery root, just mashed them with a potato masher and combined them with the potatoes, even like this, they were very good. I will have to share this recipe with my two sons and families, they always like to try something new, as well. Thank you for all the good recipes, Paula, it has been so much fun.
