Keto Green Smoothie – an almond milk smoothie recipe

What is better to start the day than a fresh green smoothie? Yes, this green smoothie is keto-approved. It has no banana, no fruits, and only healthy greens! All you need to make a creamy keto green smoothie are:

  • Avocado – ripe with no black spots on the flesh, or it will be bitter. Avocado is a delicious keto vegetable to add healthy fat and creamy texture to smoothies.
  • Spinach – for an extra touch of greens, fulfilling fiber, and almost no carbs.
  • Ice cubes – to make the drink fresh and thicker.
  • Almond butter or peanut butter – it also adds thickness to the drink.
  • Sugar-free crystal sweetener – monk fruit stevia blend or erythritol or xylitol all work well! This adds sweetness to the drink. I also like to use pineapple stevia drops with unsweetened coconut milk. Read what sweeteners are my favorite for a keto diet.
  • Keto vanilla collagen powder or your favorite Keto vanilla protein powder.
  • Unsweetened almond milk or unsweetened coconut milk.

  1. 5 stars
    I love the taste of this keto green smoothie with collagen. I didn’t add any sweetener but instead added 1/2 scoop of vanilla protein which sweetened it enough. So yummy. 😋

  2. I just brought your book clean bakery today it is very good I have been looking for better ways to do baking for a long time. I have also found lots about making breads, doing sourdough starter as I do not want to give up bread . This is so much better than bread you buy at the supermarket that is not my most flavour place as so much food there isn’t good for our health. I live in NZ too have a lovely day regards Phyllis

    • Hi Phyllis, Thank you so much for your lovely comment! Enjoy the cookbook and let me know what is your favorite recipe 🙂 xoxo Carine.

The nutritional data provided on Sweetashoney is to be used as indicative only. The nutrition data is calculated using WP Recipe Maker. Net Carbs is calculated by removing the fiber and some sweeteners from the total Carbohydrates. As an example, a recipe with 10 grams of Carbs per 100 grams that contains 3 grams of erythritol and 5 grams of fiber will have a net carbs content of 2 grams. Some sweeteners are excluded because they are not metabolized. You should always calculate the nutritional data yourself instead of relying on Sweetashoney's data.
