So I feel like you’re either rolling your eyes at me right now or you’re intrigued… A purple sweet potato smoothie with cauliflower?
Yes, we’re going there.
Ever since I tried my first purple sweet potato I’ve been obsessed. Although I didn’t buy them as much as I wanted to because for the longest time I could only find them at Whole Foods, and I don’t frequent Whole Foods as much as other grocers. But now that Fresh Thyme has started carrying them (thank the purple sweet potato gods!) I will most definitely be stocking up every time I stop… which is almost every time I head to teach or take class.
So you may be seeing a lot more purple sweet potato recipes and I hope you’re okay with that!
Another thing I hope you’re okay with is the fact that I added cauliflower into this smoothie. I know, I’m a little late to this trend. Mainly because I have to try things out for myself on my own terms first. And if you haven’t a clue what I am talking about let’s back up the bus.
Why Cauliflower in Smoothies?
Cauliflower is a great smoothie filler loaded with benefits. By adding cauliflower (pre-steamed/frozen) you bump up the nutritional profile in your smoothie without adding a ton of fruit and extra sugar.
Side note: nothing wrong with fruit smoothies! But it’s all about balance 🙂
“Cauliflower is rich in antioxidants and anti-inflammatory compounds which lower oxidative stress and the presence of free-radicals in our body.” (source)
Basically cauliflower is awesome.
Trust me – you really can’t taste it in this smoothie!

what you need
- purple sweet potato (pre-cooked and frozen)

Cauliflower Purple Sweet Potato Smoothie

I used cashew butter here because I like the sweetness that it adds. I also added ginger for some extra flavor and maca powder as a little superfood boost.
Overall I will say this purple sweet potato smoothie is not overly sweet, but it has a nice flavor thanks to the cashew butter and ginger. I just used one Medjool date to sweeten it but you could sub/add honey if you’d like.
Another way to add in a touch more flavor would be to use a vanilla flavored protein powder. I actually threw in some collagen peptides but use your favorite plant-based vegan protein powder if vegan 🙂

This smoothie kept me full for hours thanks to the fiber in the sweet potato and healthy fats from the coconut milk and cashew butter.
Sweet potato smoothies for the win!
