step by step visual instructions for how to make cauliflower creamed spinach casserole

Step 1: Allow the cauliflower to boil for at least 10 minutes. (Photo 1)

Tip: If you’d like, you can also steam the cauliflower.

Step 2: While that cauliflower boils, sauté the onion in some butter until soft, and add the spinach. Sauté until the spinach is warmed through (if frozen), and wilted (if fresh). (Photo 2 & 3)

Step 3: As soon as the cauliflower is soft, use a slotted spoon to scoop them into your food processor and blitz it with the cream and butter. (Photo 4 & 5)

Step 4: Scrape the mashed cauliflower mix back into the back, with the spinach and onion. Stir everything together with the cheese. (Photo 6)

Step 5: Add more cheese on top, pop it under the broiler until golden and bubble, and done! Scoop it onto your plate and enjoy! (Photo 7 & 8)

This is a perfect healthy (keto and low-carb) side dish since for pretty much anything, but it goes especially well with a nice piece of steak.

It’s also pretty easy to transform this recipe in a vegan creamed spinach recipe – just omit the cheese, butter and cream. I’ve tried it that way and it definitely still packs a punch in the flavor department.

Cauliflower is over-cooked when it falls apart, so be sure to only cook it until the pieces are crisp-tender.

  • 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 making it now. Realise the clove of garlic is left out from the method. I’m gonna assume it goes with the onions. Yes? 🙂
