If you’ve ever been on the fence about green smoothies, I encourage you to try this one. Similar to our keto-friendly Brownie Batter Smoothie it uses frozen veggies instead of the commonly used frozen banana. By freezing all of the vegetables first, the “green” flavour is masked a little, and the texture of the blended frozen vegetables becomes deliciously smooth.

Avocado, coconut cream and cashews add to the creaminess and help balance flavours, while the cinnamon and cacao help to flavour the smoothie – instead of anything too “green”, this smoothie is creamy and chocolatey.

While the smoothie gets some sweetness from the coconut cream, pumpkin and cinnamon, you will need to add some additional sweeteners – I find a blend of erythritol and stevia works best.

Note that this recipe serves one, however I cook up a big pumpkin to freeze, as well as freezing a few cut up zucchini and broccoli so that I always have ingredients ready to throw together to make this. It’s a great way to sneak in a few veggies into a quick, filling and refreshing breakfast or snack in those warmer months.

Please note that you need to freeze the veggies in advance. Once you have all the frozen veggies ready, the smoothie only takes 5 minutes to prepare! Low-carb sweeteners can be used to taste.

Hi Dearna,
Thanks for this great recipe!
Is there any reason to use frozen vegetables here? Can I use the fresh ones?

Hi Michelle, frozen veggies are better as they will make the smoothie much creamier. It's the consistency that will be affected.
