From all the low-carb and keto side dishes, cauli-mash is what I like to cook on most days. If you want to try something else than the regular keto cauli-mash, add some celeriac (aka celery root) and cream cheese. If you need more sides to go with your ketogenic menu, simply use the filtering options when browsing through my recipes to find your favourites!

Ingredients (makes 6 servings)

  • 1 large cauliflower (700 g/ 1.5 lb / 24.7 oz)
  • 1 small celeriac (200 g/ 7.1 oz)
  • 1/4 cup ghee, butter or lard (55 g/ 1.9 oz)
  • 1 tbsp chopped rosemary or 1 tsp dried rosemary
  • 1 tbsp chopped thyme or 1 tsp dried thyme
  • 1 cup cream cheese, full-fat (240 g/ 8.5 oz)
  • 1/2 tsp salt or more to taste
  • freshly ground black pepper
  • Optional: 4 tbsp butter for topping


  1. Peel and dice the celeriac into about 1-inch pieces. Cut the cauliflower into small florets. Finely chop the rosemary and thyme (if you're using fresh). Celeriac Cauliflower Mash
  2. Heat a large pan greased with ghee over a medium-high heat. Add the chopped herbs to the pan and cook for just about a minute until fragrant. Add the cauliflower and celeriac and season with salt and pepper. Cook uncovered for about 5 minutes over a medium-high heat and mix to prevent burning. Then, lower the heat, cover with a lid and cook for 12-15 minutes or until soft. Celeriac Cauliflower Mash
  3. When the cauliflower and celeriac are browned and soft, take off the heat and place in a blender or use a hand blender. Celeriac Cauliflower Mash
  4. Pulse until smooth. Add the cream cheese and pulse again until well combined.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Looks yummy - I bought celeriac for the first time today and can’t wait to try all the different ways to cook it

Thank you Alison, I hope you enjoy!

I made this last night. Even though I was lazy and steamed the two vegetables, it was still delicious!

Heaven on Earth.

It doesn't say how much a "serving" is. Can you please post this with your recipes?

Sure, good point! 😊 One serving is about 3/4 cup.

I didn't have all the ingredients for this so I made it differently.
I used cauliflower, sautéed scallions, sweet peppers, pink salt and pepper. I was very good. I am so learning a new way to cook.
I had never heard of celeriac before I will have to look for it in the store next time I go, I can try it out with the celeriac in it.

I've tried roasted bell peppers before and they are great for adding flavour to it! 😊
