Roasted garlic cauliflower celery root mash is an easy comfort food side dish—a great substitute for mashed potatoes!
If you like mashed cauliflower, this variation takes it up a notch. The celery root, or celeriac, adds extra creaminess and a mild celery flavor. And the roasted garlic and ghee take it over the top.
This roasted garlic cauliflower celery root mash is an easy paleo side for any meal. And if you roast the garlic the day before, like I did, it’s pretty quick too.
Of course you can roast the garlic while you prep and simmer the cauliflower and celery root. But I like to roast the garlic when I already have the oven on for something else. Or if I have the grill going, I’ll roast the garlic on the grill. It doesn’t take up much space, so it’s easy to throw in with whatever else is cooking. And it’s great to have on hand.
You may have some roasted garlic left over after making the mashed cauliflower and celeriac. I adjust the level of garlic depending on what I’m serving it with. Add more garlic if you want the roasted garlic to be the star of the show. Add less if you want just a hint of garlic. You can use the left over garlic to flavor anything you would normally add garlic to.
This is a perfect dish for Thanksgiving. It’s a great substitute for mashed potatoes—top it with easy paleo gravy.
Use it as a base for crock pot pulled pork. Or make one of my all-time favorite breakfasts—leftover mash topped with fried eggs. This post contains some affiliate links for your convenience. Read my full disclosure policy here.
