This keto smoothie recipe tastes great and provides healthy fats, lots of protein and necessary fiber, all in one glass. Better yet, the recipe comes together in less than 5 minutes and it’s sugar free! It’s a great healthy and filling breakfast or snack!
Ingredients to make this Green Keto Smoothie
- Avocado — peeled and pitted. I like using Hass avocados as they’re more flavorful. Avocados are such a great addition as they are high in healthy fats, fibre, full of vitamins and nutrients.
- Spinach or your favorite leafy greens — be sure to wash the smoothies beforehand, even if they’re advertised as pre-washed. Do not skip this ingredient if you want that boost in nutrients and fiber. Spinach is full of antioxidants as well as vitamins. Spinach is full of antioxidants as well as vitamins and nutrients as well.
- Unsweetened coconut milk or coconut water –I think this are the two best liquids to use in a green smoothie recipe. You can use any dairy free milk you prefer.
- Sugar-free vanilla protein powder — check out the recipe card down below for a link to my favourite one. You can also use a protein powder that contains monk fruit if you prefer.
- Peanut butter powder —I really love and highly recommend PB2. You can also add some flaxseed if you have it on hand.
- Freshly squeezed lemon juice — I don’t recommend using bottled lemon juice as there are preservatives.
- Optional berries – Since berries are lower in carbs, add some freeze or fresh strawberry or blueberries if you prefer.
- Top your smoothie with fresh mint and some blueberries.

Tips to keep this Keto smoothie fresh
The best time to consume this smoothie is directly after making it. Everything is still fresh, cold, and well combined.
However, if you want to drink it later, a protein green smoothie can be stored in the refrigerator for 24 hours. Store it in an airtight container, not your blender. Fill the container to the very top to keep any air out. Otherwise, the smoothie can pick up odors from nearby foods.
The colour of the smoothie might change as avocado oxidizes but it shouldn’t affect the flavour.
If your smoothie is very thick, you can serve it with in a smoothie bowl.
Use a very high-speed blender to blend all the ingredients well.
Keto Smoothie Shake
- Perfect Keto – This one is my favorite cause it’s gluten-free, dairy-free and it uses clean ingredients. There is not junk fillers.
- Vega Sport Premium Protein – This one is dairy-free, vegan and vegetarian too. It’s Keto friendly too because 1 scoop has only 5g of carbs.
- Vega Protein & Greens Vanilla – This is vegan too and there is no soy. The flavour is good too. This is keto friendly too because it 1 scoop has only 4g of carb.
- Soy protein powder will help to build bone mass and is particularly helpful in older adults.
Be sure to check for unsweetened protein powder as you don’t want to add artificial sweeteners and other fillers to the smoothies.
Fresh or frozen ingredients?
You can use fresh or frozen avocados and spinach for this green smoothie. It is definitely more budget-friendly and time-efficient to use frozen ingredients as you don’t have to wait for the avocado to ripen and risk the spinach goes bad before the avocado ripens!
There’s no need to thaw the frozen ingredients before blending them, like in my Mango Green Smoothie or Easy Apple Smoothie Recipe. Some frozen fruit like berries are good to add in your smoothie. I love mild sweetness of the berries and they are low-carb friendly.
It’ll definitely keep your smoothie cool and make the smoothie thicker, making it the perfect refreshing summer drink.
