This easy and simple mashed celeriac recipe is healthy and delicious and a great alternative side dish to mashed potatoes.
Is celeriac keto? Celery root (aka celeriac) is not technically keto, but it's got half the carbs as other root vegetables, like potatoes, so walks the line.
Mashed celery root does not have the smooth consistency of mashed potatoes. Celeriac mash is a little chunkier and not as fluffy, but still delicious. Plus it's always great to have a lot of variety in our diets.
Garnish this celery mash recipe with sliced green leaves that are growing out of the root stalk of the celeriac or with fresh parsley.

What is Celeriac?
Celeriac is the brown "knobby" root of a variety of celery. Technically celeriac and celery root are the same plant, but one is grown specifically for the root (celeriac) and one is grown specifically for the stalks (regular celery).
Choose a firm celeriac bulb with fewer knobs (they contain so much dirt sometimes) and hopefully get one with green stalks.
Green stalks on celeriac indicate how fresh it is by how firm they are. If the stalks are wilted it will be older and more fibrous. Thus it will need to be cooked longer.
How To Peel Celeriac
It's hard to peel celery root with a vegetable peeler so use a knife if that's easier.
Celery root turns brown fast once it's cut. Submerge chunks in water immediately in water and add a little vinegar or lemon juice if you've got it.
Is Celeriac Keto?
Celeriac (celery root) is lower in carb than potatoes but not as low in carbs as a cauliflower mash.
Likewise, it is a root vegetable so not technically all keto. Like carrots, you can have them on a keto diet, but do not want to eat them in large quantities or regularly.

Variations on Celeriac Mash
Don't like sour cream? Cool - use broth, heavy whipping cream, milk, or just leave it out.
Vegans use your favorite equivalent non-dairy substitutes for butter and heavy cream.
Like fresh herbs with your celery mash? Thyme is delicious as well as rosemary or sage.
Like spices? Me too! Take this easy celery mash recipe up a notch and add your favorite. I love a little bit of curry.

Mashed Celeriac (Celery Root) FAQS
Celery root is often called Celeriac or celery knob.
Celeriac tastes a bit like celery but also a bit more nutty, a little earthy, and a wee bit sweet.
Check out my easy oven roasted celeriac. Celery root is also popular in soups as chunks or purees or raw and thinly sliced or grated in salads.
Yup! Focus on the leaves as a garnish. The stalks may be fairly fibrous but would be a great addition for flavor to stocks. The stalks could also be eaten in soups if chopped small and cooked long enough to become soft.
