How this recipe came to be:
Here's what I wrote about this recipe back in 2014 -
The first time I had mashed potatoes with celery root was some years ago when a group of my girlfriends took me to a local Williams-Sonoma store for my birthday.
The store was having a holiday cooking class, and somehow, my girlfriends knew this would be right up my alley. LOL. Go figure!
One of the recipes that WS had demonstrated that fateful day was for mashed potato with celery root, and it's been on my mind ever since.
Thanksgiving without celery? Nonsense!
For me, and maybe for you too, the flavor and aroma of celery is where Thanksgiving begins!
The moment I smell celery, my mind is immediately taken to the Thanksgiving dinner table, even if it's the middle of summer in a heatwave.
Why this unique mashed potato recipe works:
The thing that stuck in my head about this delicious side dish was the way the mashed potatoes tasted just the same as my favorite mashed potatoes tasted, only a whole lot better, thanks to the complimentary taste of the celery root.
Why in the world it took me so long to make mashed celery root potatoes baffles me. But, you can learn from my mistakes and make these potatoes this year. I promise you won't be sorry!
It's a new Thanksgiving tradition that I hope will be passed down from generation to generation in my family, and hopefully yours as well.
If you're nervous about using this gnarly looking root vegetable (also called celeriac or knob celery) for the first time like I was, don't be.
What is celery root and how does it taste?
If you're nervous about using this gnarly looking root vegetable (also called celeriac or knob celery) for the first time like I was, don't be.
Celery root's flavor is mild and mellow with the texture of a potato and celery taste, only not as overbearing and intense.
And, as a bonus, there are no strings attached…celery strings, that is!
How to cut and trim celery root:
How to make mashed celery root potatoes:
- Trim, peel, and chop the celery root into 2" chunks.
- Peel and chop the russet potatoes into 2" chunks.
- Add them both to a large pot and cover with cold water.
