Keto Cauliflower Mac ‘N Cheese

Easy & One-Pot!

When it comes to this keto mac ‘n cheese calling it easy just doesn’t cut it… it’s suuuper easy! Think one pot and only a handful of pantry staples, making it an ideal weeknight side or meal!

The trick here is to cook the cauliflower in a browned-butter and heavy cream base, rather than boiling it in water first. This way you’ll achieve true creamy and cheesy glory!

Plus, feel free to play around with a few things! For instance, I love doing a sharp cheddar and gruyรจre mix when I’m feeling extra fancy. And adding in some deeply caramelized onions at the end also takes it to a whole other level!

Ultra cheesy and warming-to-boot, this keto cauliflower mac and cheese is bound to become a favorite low carb side (or ahem, comforting main!). 




  1. Break up the cauliflower head into bite-sized florets and set aside. 

  2. Add butter to a Dutch oven or pot over medium/low heat and cook, stirring every so often, until fully browned (4-6 minutes). Add heavy cream, mustard, garlic powder, black pepper, a generous pinch of salt and stir until combined. Add in the cauliflower bites, stir until evenly coated, cover with lid and simmer until softened but still retain a bite (10-15 minutes). Feel free to add a little extra salt now, keeping in mind you'll be adding the cheese still. 

  3. Make an arrowroot or konjac powder slurry (i.e. mix the powder with a couple tablespoons of cold water). Add it to the cauliflower mixture and stir until thickened (I've noticed various brands behave a little different, so just add it little by little to taste). Add in the cheese,  stir until melted and serve right away!

  2. Haley says:

    another unbelievable recipe! If I had one last meal on earth it would be mac and cheese so I was a little skeptical, but shame on me because all your recipes are wonderful. I scarfed this down like nobody’s business, and it was so so easy to put together!! A really price conscious excellent quick meal. Thank you for your amazing ideas!!

    • Paola van der Hulst says:

      Lol! So awesome to hear Haley! Though tbh I was also highly skeptical of this one before whipping it up ๐Ÿ˜‚!

  3. Ryan says:

    Wow!! So good. And super easy!! I used cheddar and cream cheese. I also added chicken. Topped off with hot sauce.
    So amazing!!!

  4. Dorothy says:

    I’ve made this a couple of times now and love it! I make a batch of this for me and a batch of this sauce with pasta for the rest of the family. Everyone loves it and it’s super easy. Thank you!

  5. Ketoheroes says:

    Thanks for this recipe! Itโ€™s literally the first couliflower dish thatโ€™s w actually liked and ate happily!

  6. Cheryl says:

    Thank you for the great recipe! We made this tonight & used Xanthum gum cuz it’s what I had. My kids loved it! Next time I’m gonna add a wee bit of cream cheese ๐Ÿ™‚ I love this site; thank you for your hard work!

  7. Cherie says:

    Wow !!! Thank you so much !!! I made this tonight and it was the best ever. My fussy son was raving. Next time I need to make double !

  8. Marie Miller says:

    Why call this cauliflower Mac & cheese when there is no โ€œMacโ€ in sight? How about cauliflower with cheese sauce?

  9. Hunter says:

    When recipes donโ€™t have a serving size listed are the macros calculated for the entire dish and then you devide by how many servings you want out of the dish?

  10. Robin L Cartwright says:

    I get so aggravated at these recipes that look so yummy but do not give a serving size! When you are looking at a whole pot of whatever it is impossible to “see” what a serving size is when all you give is a 4 servings per recipe!

    • Paola says:

      Instead of getting aggravated with free content Robin (!!) just calculate your own macros according TO YOUR serving size ๐Ÿ˜‰ keep in mind that it’s hard for me to say 1 cup or 1/2 cup (or whatever) with savory recipes (unlike desserts were you can say 1 muffin…) as it will depend A LOT on how you cut your cauliflower etc… xo!

    • Paola says:

      Itโ€™s a low glycemic flour and in small amounts youโ€™ll be fine (youโ€™ll get more carbs from eating a strawberry). But m if thatโ€™s not cool. Thatโ€™s why I suggest konjac- another thickener thatโ€™s a little harder to find but nil carbs

      Ps remember that keto is a metabolic state, not a list of foods ๐Ÿ˜‰

    • Angela Altomare says:

      There are 4.7g of carbs per teaspoon of arrowroot powder, so given that this serves approximately 4 people, that’s a gram or 2 of carbs per person of ‘thickener’. Therefore, it’s really not a game changer.

      • Paola says:

        Itโ€™s even less than that because 1tsp only weighs 3g (so net carbs are something like 2.9)… less than a carb a serving

  11. Alicia says:

    Is xantham gum an acceptable substitute for arrowroot in this recipe?
