My creamy avocado blueberry smoothie contains only 4 simple and natural ingredients. It is a keto blueberry smoothie recipe - packed with nutrients and dairy-free! I enjoy it as a healthy, light breakfast or as a post-workout snack.

This low carb blueberry smoothie recipe is so refreshing, creamy and naturally sweet. And don't even get me started on how fruity it tastes! It is hard to believe that you can make something this delicious with such few ingredients.
Sugar free friends, I used to drink plenty of smoothies before I started eating low carb. I'd add lots of fruit and ALWAYS a banana to thicken it. Which tasted great, but essentially I was drinking a huge glass of sugar.
The good news is that there is no need to give up fruity smoothies when you are on a low carb or keto diet. You just have to be mindful of WHICH fruit you put in and HOW MUCH. (Hint - blueberries are a great option - and so is avocado!

Ingredients
Let's gather what you need for a HEALTHY keto blueberry smoothie:
- Blueberries: I'm using frozen berries, which help thicken the smoothie.
- Unsweetened almond milk - or use any dairy-free milk of your preference. I like almond milk here because it is especially low in natural sugars.
- Avocado: I added ¼ small avocado. This makes the smoothie super thick and creamy. Avocado is incredibly nutrient-rich. It contains nearly 20 vitamins and minerals, plus healthy fats.
- Vanilla extract: This adds a mellow, warm flavor. It's not entirely essential, but to me the vanilla adds the little extra that makes the smoothie taste special and exciting.

Instructions
There really is only one step: Put all ingredients in a blender jug and blend until smooth!
High-speed blenders will give the smoothest, creamiest result.

Katrin's Top Tip
I love my smoothies cold and thick, that's why I use frozen blueberries. (These are also cheaper to buy than fresh blueberries!)
If you use fresh blueberries, add a few ice cubes to the smoothie.
As an alternative, you can also use frozen chopped avocado. I often buy a larger amount of avocado when they are cheap. Then I cube the flesh and freeze it in bags.
Recipe Variations
MORE SWEETNESS: If you have a sweet tooth, add 1-2 teaspoons of powdered sweetener such as allulose, xylitol or erythritol. Or, add a few drops of stevia.
MORE THICKNESS: For a thicker smoothie, add 1 tablespoon almond butter or peanut butter.
GIVE IT ZING: As an alternative to the vanilla extract, try using a squeeze of lemon or lime! A few leaves of fresh mint work well in this combination.
GET YOUR GREENS: I sometimes add a handful of spinach leaves. Just be aware that this will change the colour and make the smoothie a bit greyish. If you use spinach, add it to the blender first.
Recipe FAQs
Swap out some of the almond milk with greek yogurt or coconut yogurt for a tangy twist. Adding coconut cream would make this smoothie very filling.
Another way to up your fats intake is to add a tablespoon of MCT oil!
You can get the same creamy thickness by using collagen powder or protein powder. For both powders, I'd go with 2 tablespoons.
Use strawberries, raspberries or blackberries instead of blueberries - or a berry mixture.
Heavy whipping cream and cream cheese would definitely taste good in a keto blueberry smoothie. But I'll be honest with you - this would make it less of a healthy smoothie and more of a dessert.
Storage
Any avocado smoothie with blueberries tastes best fresh. Here are my tips if you need to prepare it ahead:
Refrigerator: Store the smoothie in an airtight container for up to 1 day. I just put it in a glass and press cling film directly onto the smoothie surface so that there are no air pockets. Stir before drinking in case the ingredients have separated.
Freezer: Pop it into an ice cube container and freeze for up to 3 months. When you want to drink it, release the smoothie cubes into your high-speed blender and process to the desired consistency.

Weight stalling can have many different reasons. Too much food is definitely one of them! I'm focussing on plenty of green veggies this month to make up for December 🙂
