How to Make a Keto Diet Green Smoothie Recipe

Gather eight ingredients, and you’ll be halfway to making a delicious vegan green smoothie recipe with avocado in five minutes or less!

It’s a simple job of tossing the ingredients into the blender and clicking it on. What a quick fix when you need nourishment fast!

You can customize this smoothie any way you like, but I highly recommend trying it as is because, well, it’s delicious!

Avocado – The incredibly versatile avocado is an excellent source of healthy fats, potassium, and lutein. (1) It also gives this smoothie a rich, creamy texture.

Spinach – If you’re looking for a way to add spinach to your diet, blending it in a smoothie is super easy. If needed, substitute for sprouts, kale, or other leafy greens. 

Coconut milk – Along with a high amount of MCTs, (2) coconut milk also contains electrolytes plus anti-inflammatory and anti-viral properties. (3, 4, 5)  This dairy-free milk gives the smoothie a velvety consistency; It can be diluted with water if you want to reduce the overall caloric load. You can also substitute with nut or seed milk, if desired.

Lemon juice – Delivers a sweet tang to this keto green smoothie and keeps the flavor light and interesting. 

Vanilla extract – Doesn’t vanilla extract make everything better? Add a little sweetness in a splash.

Mint – Mint extract or a small handful of mint leaves gives a refreshing mint taste and aroma. 

Liquid sweetener – Use store-bought or Homemade Stevia Extract.

Ice cubes – Add more or less ice to get the texture you love. I like a thinner smoothie and blend 1 cup of water with a handful of ice cubes. 

Have you ever considered freezing leftover tea in ice cube trays and substituting them in recipes like this smoothie? Not only are the ice cubes a fun way of adding flavor, but they are also a shortcut for saving leftovers and stretching ingredient across multiple recipes.

Optional Add-ins

Add a moderate amount of berries like blueberries, strawberries, or raspberries to mix it up.

Cacao nibs give the smoothie a nice crunch and a chocolate flair.

Spirulina is a complete protein that will spike your smoothie with vitamins and minerals.

If you do ok with dairy, use raw milk yogurt as the liquid base instead.

Consider slicing mango or other fruit to get kids to eat healthy foods.

Begin by choosing a perfectly ripe avocado. Test the firmness by applying gentle pressure of your fingertips around the top where the stem was. The fruit should give a little. To me, the avocado makes this just like a milkshake, but it’s completely dairy-free!

Then, open up a can of coconut milk and combine it with the avocado in a blender. If you want a BPA-free option, choose a coconut milk product from a carton instead. Please, read the label carefully and buy one without sugars and chemical preservatives.

Add spinach, either fresh or frozen. Heads up, if you use frozen spinach, it may make your smoothie more runny. If that’s the case, you might not want to add any ice cubes.

Next up, add the lemon juice, vanilla extract, and mint. If you have fresh mint, a handful of the leaves will do. Otherwise, mint extract or frozen mint tea ice cubes will work just fine.

Add all the ingredients to a blender and blend on high until smooth. Taste and adjust as desired. 

Keep in mind that taste testing is important when you are making green smoothies on keto. Get comfortable tweaking the flavor to best fit your liking. 

Finally, pour into a glass and serve immediately. YUM!

Low Carb Green Smoothie FAQ

If you’re new to low-carb meal prep or don’t have much experience with keto smoothies, you might be asking these common queries. Let me help!

How many calories in a green smoothie?

There are 480kcal in this recipe. The combination of coconut milk and avocado makes this one exceptionally rich in calories from healthy fat sources. If you’re interested in a lower calorie option, see the substitution ideas listed above.

How to make a green smoothie taste good?

If you follow a tried and true recipe like this one, you are off to a great start. All the ingredients are perfectly balanced to give you a creamy, refreshing, slightly sweet keto green smoothie.

Can you lose weight drinking green smoothies?

High-fat, low-carb smoothies like this one will satiate you and provide ample fuel for a ketonic metabolism. However, by themselves, they don’t guarantee fat loss. While they can be part of the whole picture, expecting to loose weight just by eating green smoothies is unrealistic.

How long do green smoothies last in the fridge?

Smoothies aren’t the best option for meal prep because they usually don’t save well unless you freeze them. Instead, I recommend drinking the smoothie shortly after making it.

    I’ve been trying to incorporate more smoothies into my diet, and this recipe is definitely more elaborate (and healthier) than my boring frozen fruit, protein powder, and almond milk usual. Fresh, packed with nutrients, and delish!

    This smoothie is amazing! I love how it’s got such a fresh and light flavor. It’s great for when you’re feeling a little under the weather, but also when you have a lot of energy after a good workout. The best part is that it’s super easy to make.
