Green Keto Smoothie


Low carb kale, cucumber, and celery come together with delicious healthy fats like avocado and peanut butter to make this easy Green Keto Smoothie a nutritional powerhouse!

Fruit smoothies get a lot of attention, but if you’re looking for something super healthy and refreshing, green smoothies are the way to go!

Green smoothies are made with vegetables and low-sugar fruits (like avocado), so while they’re just as tasty, they are actually much healthier for your blood sugar levels.

And this green keto smoothie recipe is an excellent way to get some healthy greens and fats into your diet without causing a blood sugar spike!

The peanut butter, avocado, and almond milk add creaminess to the smoothie. They give it a dreamy texture that complements the refreshing, slightly zingy flavour perfectly. It’s also entirely vegan!

This smoothie isn’t “sweet,” but it does have slightly sweet undertones from the peanut butter and almond milk. It’s a wonderful balance that’s perfect for a hot summer day or after a hard workout.

It also only takes a few minutes to put together. All you need to do is combine the ingredients in a blender!

How to make this green keto smoothie recipe 

Even on the busiest of mornings, this easy smoothie recipe can be whipped up in a matter of minutes. And it’s the perfect fuel you need to start your day!

Step 1: Add all of the ingredients to a high-speed blender.

Step 2: Pulse to combine, stopping to scrape down the sides if necessary.

Pour your smoothie into a glass and enjoy!

I recommend garnishing with a little fresh mint for an extra refreshing taste.

Picking your ingredients

This low carb smoothie is best made with unsweetened almond milk. It has very few calories but adds a lot of flavour and creaminess.

You could substitute coconut milk or canned coconut cream for an even creamier smoothie. These will add calories, so they’re ideal if you’re drinking this smoothie as a meal and want it to keep you satisfied for several hours. They also increase the amount of healthy fats!

If you don’t mind using non-vegan ingredients, you could use regular milk instead, but keep in mind that this will increase the carbs.

To increase the amount of protein, feel free to add a scoop of your favorite protein powder! Vanilla or unflavored protein powder (like collagen protein) would work the best. I wouldn’t recommend chocolate protein powder based on the other flavors in this smoothie. Plus, it will turn the mix a strange brown color, and no one wants that!

Tips for your perfect smoothie

A high-speed blender is essential for achieving the desired texture in this recipe!

Blending fibrous vegetables like celery and kale can be time-consuming. When blended until silky smooth, this smoothie is at its best.

As I mentioned, this is not a sweet smoothie. It has a sweet undertone from the almond milk and peanut butter, but the majority of the ingredients are low-sugar vegetables. So if you would like to have a sweeter smoothie, add in a couple of drops of liquid stevia.

Prior to blending, I like to chill all of my ingredients in the refrigerator. When everything is chilled, the smoothie is extra refreshing, especially on a hot day or after a hard workout!

One piece of advice I have is to buy avocados in bulk and freeze them once they have ripened. They’ll keep for a long time, and then you can have one whenever you want a low carb green smoothie!


The key to a green keto smoothie is to include lots of veggies for flavor and color, but to keep the carb count low.

This smoothie has 8.6 grams of total carbs per serving and 3.8 grams of fiber. This means there are 4.6 grams of net carbs. And with the 10.8 grams of healthy fat per serving, this smoothie is great for anyone following a keto diet!

You don’t have to be on the keto diet to enjoy this smoothie. The healthy fats will keep you going for hours, and the low carbs will keep your blood sugar stable.

It’s a tasty, refreshing way to get your veggies and fuel up for the day!


The lemon juice in this recipe helps to preserve the smoothie and prevents it from browning.

Any leftovers can be kept in an airtight container in the refrigerator for up to 3 days. Because this recipe makes two servings, you can eat half right away and save the rest for later!
