How To Make Keto Green Smoothie

What is better to start the day than a fresh green smoothie recipe? Yes, this green smoothie is keto-approved.

Ingredients

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 with MCT Oil.
  • Unsweetened almond milk or unsweetened coconut milk.

Instructions

Making this keto green smoothie is ridiculously easy.

Combine all the ingredients in the jug of a high-speed blender and blend for about 30 seconds.

Tip: Adjust Thickness

Adjust the thickness of the smoothie with more almond milk. If it’s too thick, add a tablespoon of almond milk and blend again. If it’s too runny, add a couple of ice cubes.

Transfer the smoothie to a tall smoothie glass and decorate it with cocoa nibs.

Taste Changers

If you want to alter the taste of your green smoothie, you can add the following ingredients to the blender:

  • Lemon Juice: for a tangy flavor.
  • Strawberries or Raspberries: for a sweeter, pinkish smoothie.
  • Cucumber: for a boost in freshness.
  • Celery: for an almost spicy taste.
  • Chia Seeds: for an extra boost of antioxidants.
  • Vanilla Extract: for a sweet taste.
  • Melted Coconut Oil: for a boost of fat.

Storage

Unfortunately, you can’t really store this smoothie. If you leave it to settle, the phases will split and it won’t be enjoyable.

Allergy Swaps

You can definitely swap some of the ingredients in this low carb green smoothie.

  • Almond Milk: replace it with unsweetened coconut milk, or unsweetened oat milk. Regular dairy milk is not keto-friendly.
  • Almond Butter: you can use any nut butter like peanut butter, or use sunflower seed butter for a nut-free alternative.
  • Erythritol: any crystal sweetener will do, so you can also use allulose or your favorite keto sweetener.
  • Collagen Powder: you can substitute it with any keto-friendly protein powder.
  • Spinach: you can swap the fresh spinach for fresh curly kale.

    9 Thoughts On Keto Green Smoothie with Collagen Protein Powder

  1. Hello Carine I know you are a keto blog so this is just going to sound silly (and annoying) but I just wanted to let you/others know that you have this smoothie listed under “vegan diet” but the Collagen powder used here is not vegan (nor vegetarian) so you may want to make a note of that.

    Otherwise, I love your recipes and have your vegan, keto eggless bread in the oven right now!!

    Cheers!

    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. 😋

  5. 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
