Roasted Cauliflower MashPin itFollow us 148.4k

Move over cauliflower mash, there’s a better mash in town! This keto roasted veggie cauliflower mash is packed with flavor from roasted cauliflower, caramelized onion, garlic, and thyme plus buttery ghee.

What could be better? This mash goes great with any roasted meats, steak, meatballs, and stews like this Low-Carb Osso Buco or our Instant Pot Red Wine Pork Stew!

You’ll start by slow roasting the veggies, and then give them a whirl in the blender or food processor with a bit of gut-healing bone broth (or chicken stock or vegetable stock if you follow vegetarian keto diet) and more ghee. This mash is rich, comforting, and totally keto friendly. Let us know what you serve it with in the comments below!

I really want to try this I am a huge mashed potato fan! Do you think it would be possible to make this from existing cauliflower rice I have? I am thinking to give it a good roast in the pan together with the other ingredients. Thanks so much!

I think that might be fine. If you use cauli-rice, add some vegetable or chicken stock to soften it and then blend until smooth. Just to clarify, roasting gives the mash a slight caramelised flavour. If you prefer a more neutral cauli-mash (still full of flavour!), this is a good recipe to start with: Cauliflower Mash with Roasted Garlic & Thyme

Perfect, thank you so much 😊

Cauliflower mash can made extra fluffy by cracking an egg into it while being processed

Thank you Olga, that's a great tip!

Recipe says 1/4 cup Ghee plus 2 Tablespoons (for later)...However, in directions it says 1/2 cup Ghee and later the 2 T..? I can never get recipe as shown to print? So tired of copying and pasting....What am I not doing?

It is 1/4 cup (60 ml) - the fraction was mistyped (now fixed) in the instructions but is correct in the video, ingredients and in ml. I'm not sure why you can't print because every recipe on my blog can be printed using the "Print Recipe" or downloaded as PDF using the "Download Recipe" option (see below the list of ingredients). I hope this helps!

Omg this twist on cauliflower mash is just amazing, never having plain caulimash again ...
thanks KetoDietAop xx
