This purple sweet potato smoothie recipe tastes like a thick and creamy milkshake, but it is made with nourishing ingredients that help keep you full and energized. Naturally sweetened with dates and flavored with cinnamon and vanilla, it basically tastes like dessert. This no-fruit smoothie skips the usual bananas and berries, making it a delicious way to add a vegetable to your breakfast routine.

Smoothies are typically known for sneaking more fruit into your diet, but they can also be a delicious way to enjoy more vegetables. And this one proves that vegetable smoothies definitely do not have to be green. I've been chasing the rainbow with my smoothie creations lately, and this vibrant purple version may be my favorite yet!

If you're searching for a no-fruit smoothie without bananas or other traditional smoothie fruits, this recipe is for you. Purple sweet potato gives it an extra-thick, creamy texture and naturally gorgeous color.

I originally found frozen purple sweet potatoes in the freezer section at Whole Foods, but you can also cook and freeze your own. Any variety of frozen sweet potato will work in this recipe, although the color will change. An orange sweet potato will create an orange smoothie like my Sweet Potato Pie Smoothie, while a white sweet potato will keep it a more neutral color.

If you want to lighten it up, replace half of the frozen sweet potato with frozen riced cauliflower. Cauliflower has a mild, neutral flavor, so it adds volume and creaminess without overpowering the smoothie.

This purple sweet potato recipe also includes almond milk, almond butter and hemp seeds for plant-based protein and healthy fats. Purple sweet potatoes contain vitamin B6, vitamin C, potassium and fiber. They are also rich in anthocyanins, the antioxidant pigments that give them their gorgeous purple color.

Best of all, this smoothie has been a grand-slam hit with my kids. They love its sweet, creamy flavor and, of course, that beautiful purple color.

Have I convinced you to add a vegetable to your morning smoothie? This creamy purple sweet potato smoothie is nourishing, satisfying and decadent enough to taste like dessert.

Description

This creamy Vegan Purple Sweet Potato Smoothie tastes like dessert but is packed with nourishing ingredients to keep you full and energized. Purple sweet potatoes contain vitamin B6, vitamin C, potassium, fiber and are rich in anthocyanins, the pigments that give them their gorgeous color. This no-fruit smoothie skips the usual bananas and berries, making it a delicious way to add a vegetable to your breakfast routine.

Ingredients

Units Scale
  • 1 cup frozen purple sweet potatoes (I buy the store-bought cubed frozen bags)
  • 1 cup unsweetened plant milk, chilled (almond milk, oat milk or cashew milk)
  • 2 tablespoons raw almond butter
  • 3 soft pitted Medjool dates
  • 2 tablespoons rolled oats (GF if desired)
  • 2 tablespoons chia seeds and/or hemp seeds
  • ½ teaspoon pure vanilla extract
  • ½ teaspoon cinnamon
  • ⅛ teaspoon cloves (or nutmeg)
  • 1-2 cups ice cubes (depending on how frosty you like it - I like 2 cups)
  • pinch of salt (don't skip!)
  • garnish options: vegan whipped cream and granola

Instructions

  1. Place all ingredients in a high speed blender and blend until smooth and creamy. You may want to put the dates at the bottom to ensure they get blended in well.
  2. Taste and add more dates for sweetness if desired. You may also want to add more cinnamon or vanilla for added flavor. I like to add extra ice for a frostier smoothie.
  3. Pour into 2-3 glasses. Garnish if desired and enjoy immediately.

      I buy it frozen and I believe it is raw.

        I had the same question! I have some raw purple sweet potato and would love to try this. Googling around makes me think that frozen sweet potato (didn’t know one could buy that!) is cooked or partially cooked before it’s frozen. If anyone tries the recipe with raw frozen sweet potatoes, would love to hear how it turns out!

          This is what I use: https://www.stahlbush.com/product/frozen-sweet-potatoes/ - The Stahlbush Island Farms frozen sweet potatoes which are blanched (lightly cooked) before freezing — they are not raw. Blanching is a standard process used to preserve color, texture, and nutrients while stopping enzyme activity before freezing. This means they’re partially cooked and can be quickly heated or roasted from frozen. I hope that helps. Please let me know if have any follow up questions.
