Cucumber Smoothie


This cucumber smoothie is a creamy and refreshing take on a green smoothie.

Enjoy this frothy green smoothie made of cucumbers and avocado without having to use a banana or milk. This cucumber smoothie will provide hydration and keep you satisfied without using dairy or sugar.

This cucumber smoothie makes the perfect breakfast or mid-day sip when you need a little bit of tranquility or to quench your thirst. Since it has cucumber in it, you know you are getting a mild flavor with lots of hydration. I love using cucumbers in other surprising recipes where you wouldn’t think to add it – like my keto apple pie or my cucumber lime margarita.

This delicious frothy smoothie is creamy and slightly sweet and we didn’t have to use an high sugar fruit like bananas or pineapple to sweeten it or making it smooth. Instead we pair this with avocado to get that same creamy texture and mix it in with nut milk and a bit of keto sweetener. If you love smoothies in the morning, this smoothie recipe will keep you satisfied and moving all morning long.

Key ingredients

  • Ice – Ice will help create a slushy consistency and help keep your smoothie cold.
  • Cucumber – Cucumber’s are high in water so this is a hydrating smooth. It is also filled with fiber to help promote regularity.
  • Avocado – Avocado is used for creaminess. Most cucumber smoothie recipes include a banana for sweetness and to get that smooth, creamy texture. Bananas have a lot of sugar so they really aren’t as healthy as most would think.
  • Nut milk – Any nut milk will work (macadamia nut milk, almond milk, coconut milk, even cashew milk).
  • Sweetener – This is an optional ingredient but does help with the flavor. I like to use a sugar-free honey which is honey flavored allulose syrup.

    Flavor variations and add-ins

    • Strawberry Cucumber Smoothie – Add in 1/4 cup sliced strawberries or even raspberries. You can even omit the additional sweetener if you are adding a sweet low carb fruit like berries.
    • Cucumber Mint Smoothie – A few sprigs of mint leaves to this cucumber smoothie recipe will add a different refreshing flavor and may help with digestion.
    • Cucumber Lime Smoothie – Add in a few tablespoons of fresh lime juice for a thirst quenching twist on this hydrating smoothie recipe. Don’t have lime juice? Try lemon juice instead.


    Try adding in these for a different texture or flavor:

    • Yogurt – Look for a low carb or sugar free yogurt. Plain Greek yogurt can also be used. This will add a slight tang and increase the creaminess of the smoothie.
    • Protein powder – Make it a complete meal for breakfast by adding a scoop or two of protein powder. Unflavored or vanilla flavored protein powder works best in this recipe.
    • Spinach – For a little extra to your green smoothie, add in a handful of spinach leaves to create a spinach smoothie.
    • Kale – For more nutrition, add a few kale leaves for a healthy smoothie.
    • Almond butter – Need a little extra protein and fat? Add a tablespoon or two of almond butter or your favorite nut butter.
    • Chia seeds – A few teaspoons of chia seeds will help thicken your cucumber smoothies and keep you satisfied all morning.
    • Ginger – Adds a little spice and kick to your smoothie. Plus ginger helps with digestion.

    1. I tried this yesterday morning. It was very good. I am going to try the alternative as well – ginger and yogurt instead of avocado. Thanks!!
