How to Cook Celeriac


Celeriac is SO easy to cook

Celeriac, like all root vegetables, is the ultimate in comfort food.

You cook celeriac as you would any of the popular root vegetables, roast them, mash them, simmer in a stew or blend them for soups.

I love celeriac with potato, either mashed, or baked in a casserole. Celeriac makes great wedgies too!

Here's my oven baked recipe, for creamy celeriac and potato casserole with cheese.

Where do you start with a Celeriac?

If you've just met a celeriac for the first time, you will be forgiven for scratching your head and wondering just where to start on this odd looking bulbous vegetable.

It may not be the prettiest vegetable, but it's simple to cook and tastes like a mixture of celery and parsley. It can be eaten raw as long as you peel off the thick skin.

Prepare the Celeriac

I've certainly grown better looking vegetables but you can't judge a book by its cover or a veggie by its skin.

I've spotted this in the supermarket but always ignored it because I didn't know how to cook it. Now I do. I will try some this week.

Your celeriac lens is not being fully appreciated right now, so I'm giving it a little love and featuring it on my celeriac lens. We celeriac fans must stick together!

Lynne Schroeder from Blue Mountains Australia on March 06, 2011:

Have been meaning to try it - might just have to now.

Great lens! I'm ashamed to say I never heard of Celeriac until now.

Gordon N Hamilton from Wishaw, Lanarkshire, United Kingdom on March 06, 2011:

Great lens and fabulous recipes, Susanna. You have convinced me. Believe it or not, I see celeriac in the supermarket all the time but not only have I never cooked it, I've never even tasted it. Definitely going to give it a go.

anonymous on March 06, 2011:

Great lens, Susanna! I've never heard of this. Sounds yummy!

Nancy Tate Hellams from Pendleton, SC on March 06, 2011:

Wow, you sure did a super job on this one and I learned so much. I do remember reading a lens or two about Celeriac but have never tried it and this recipe makes Cooking with Celeriac something that I think I would like. Your Celeriac and Potato Gratin Recipe sounds yummy. I can't even imagine what Celeriac must taste like so guess I will have to give it a try. Thanks for the heads up!
