  • 2 cups frozen spinach
  • 4 cups cauliflower (we used a small head of cauliflower and cut it into small florets)
  • 1 onion (diced)
  • 1 garlic clove (minced)
  • 1/2 cup mozzarella (shredded – plus a little extra for on top)
  • 2 tbsp heavy cream
  • 1 tbsp butter
  • 1/2 tsp ground nutmeg
  • to taste salt and pepper


  • Turn on your broiler.
  • Bring a medium sized pot of salted water to the boil. Once it boils, add the cauliflower florets and boil for approximately 10 minutes (or until soft).
  • While the cauliflower boils, caramelize the onion in a little bit of butter and oil [butter for flavor, oil to keep it from burning] until soft and translucent and and then add the spinach and nutmeg. Cook until the spinach is warmed through.
  • When the cauliflower is cooked, use a slotted spoon to scoop the florets into a food processor. Add the cream and butter. Blitz the cauliflower until smooth. Taste and then season with salt and pepper.
  • Now mix the cauliflower, spinach/onion and cheese together, taste test and add more salt if needed, and scoop into a cast iron pan or small baking dish.
  • Slide under the broiler until the cheese is golden brown and bubbly.

Tips and Tricks:
1. Adjust the spinach and cauliflower quantities to your own tastes if you’d like: More spinach for a more “substantial” side dish, more cauliflower for a “creamier” dish. We prefer a “creamier” dish.
2. Do not underestimate the power of salt with making a delicious Cauliflower Mash – the water you boil the cauliflower in should be WELL salted – think sea water!

  1. Hi,
    I’m in the process of making this wonderful looking dish. I have a feeling I over bought on the cauliflower. Would you be able to estimate how many cups of boiled cauliflower you put in the food processor? Also, what size baking dish are you using? In the video the dish is rectangular, but I’m guessing it’s not as big as a 9″ X 13″? Thanks for the advice and sharing the recipe!

    1. Hi Kelly! The size of the dish I used was a 10”x6” – I will add this information to the recipe card. We are in the process of updating a lot of our older recipes.

      Also, I think the head of cauliflower we used got us about 2-3 cups of cauliflower. Hope that helps!

  2. Interesting post!! I’ve started LCHF a month ago, and so far I am getting used in this way of eating. I love that I don’t feel bloated all the time, And I’ve never felt so much better like this before. I think I found the best diet for me!! Thank you for this awesome recipes.

  3. Anything besides spinah you would suggest? Kale? Swiss Chard? finely chopped brocolli?

    1. Kale would definitely do great, Swiss chard as well. And who knows, maybe even broccoli…I might give that a try myself!:)

    I am going to do a variation of this as a pasta sauce. And imagine cauliflower/spinach toast like avocado toast.

    I read the recipe and had to make it right away (after midnight) So I used what I had. I boiled the cauliflower, moved it to blender with a slotted spoon.
    It was slow blending so I added a tablespoon of butter. The I decided to just put in the fresh spinach. It gave it a crisp taste. I couldn’t decide if I should use unflavored yogurt or coconut milk. I seasoned it with a onion/garlic/parsley spice mix from Trader Joe’s. I used Oxacan grated cheese because it melts so well.
    Next time I will follow the recipe but I was delighted with my results. I ate half of it for dinner. The rest will be beaten in with some eggs for breakfast.
    This would be a great potluck dish–especially since it can be made vegan so easily.
    This is the first of your recipes I have tried–now I am going to go down the list and try others

    I cook every day but have never tried cooking cauliflower. I skipped over all the recipes for it thinking surely it wouldn’t taste good as a replacement for rice or mashed potatoes. So I saw this recipe and had everything except the cream so decided to try it. I didn’t add the cloves because I only had whole cloves and didn’t feel like processing them. I used 2% milk instead of cream and threw in a little parmesan cheese with the mozzarella. I didn’t see where in the recipe to add the garlic so I put it in when the spinach was almost wilted. I thought it was really good, my husband who resembles a three year old when trying new foods said it was ok. I would make it again but without the nutmeg, to me it gave an odd flavor but maybe that’s because I didn’t use the cloves. I’m for sure a new fan of cauliflower and can’t wait to try it other ways.
