How To Make Cauliflower Smoothie

Don’t worry you won’t taste the cauliflower in this smoothie recipe. The trick is to use frozen raw cauliflower; uncooked cauliflower that has been frozen has no flavors.


Frozen cauliflower, when blended with other sweet ingredients, is absolutely tasteless. All you will enjoy is the added nutrients from cauliflower, fiber, and creaminess.

Ingredients for the Cauliflower Smoothie in small bowls and cups with labels.

  • Nut Butter – This adds healthy fats and creaminess to the smoothie while masking the cauliflower taste. Use any flavor like peanut butter, almond butter, or cashew butter.
  • Frozen Cauliflower Rice – I buy ready-made frozen cauliflower rice, or you can pulse the raw cauliflower florets into rice in a food processor. Then, freeze cauliflower rice and use it in the smoothie recipe. Don’t use cooked or steamed cauliflower in this recipe. It won’t add the same creamy texture. The cauliflower must be raw and frozen for best results and neutral flavors.
  • Ice Cubes
  • Almond Milk or coconut milk
  • Greek Yogurt or plant-based yogurt if you cant have dairy.
  • Sugar-Free Maple Syrup or any liquid sweetener you love, like honey, maple syrup, or agave syrup.
  • Vanilla Extract
  • Cinnamon
  • Protein Powder – This is optional, but it adds proteins and thickens the cauliflower smoothie recipe.


Step-by-step instructions on how to make Cauliflower Smoothie
  1. Add all the ingredients in any order in a high-speed blender and blend on high speed until creamy and smooth.
  2. Taste and adjust. If you feel the cauliflower flavor is too much, that’s fine. Simply add more vanilla extract or sweetener to cover it.
    If too liquid, blend in more ice cubes for a frothier texture.


Serve the smoothie in a glass decorated with a drizzle of extra peanut butter. Add a drizzle of natural peanut butter on top of the smoothie just before serving.
