Need more keto smoothies? Try my keto strawberry smoothie, keto peanut butter smoothie, and keto green smoothie next. I love starting my mornings with a big, bright smoothie. When I need said smoothie to fit my low-carb lifestyle, I opt for my favorite low-carb fruit: blueberries! My blueberry smoothie is light and bright, with blueberry flavor to boot. It has the texture of a milkshake, but it’s packed with vitamins, minerals, and antioxidants. Best of all, it’s ready in seconds (yes, literally seconds!). 

Why I love this recipe

Made with 3 ingredients. All you need are frozen blueberries, milk, and almond butter.  The perfect texture. I’ve noticed blueberry smoothies can be hit or miss. Sometimes, the skins gel up and gives it a chunky, unpleasant texture, but I’ve never had that problem with my recipe.  Easy to customize. Add in other low-carb fruits, swap the milk, or blend mix-ins to completely change the flavor.  So healthy. Blueberries are full of antioxidants and fiber while being low in carbs and calories. The almond butter adds healthy fats, making for a well-rounded drink.

Ingredients needed (and substitutes)

Blueberries. You MUST use frozen blueberries, not fresh. I tested fresh blueberries, and they made for a thin and watery smoothie. Milk. I used unsweetened coconut milk, but any low-carb milk, like almond or soy milk, works.  Almond butter. Adds extra staying power and a richer flavor. Peanut butter or cashew butter can also be substituted.

Arman’s recipe tips

Make it creamier. Swap some of the milk with Greek yogurt or sugar-free condensed milk. For a low calorie alternative, blend ice cubes. Sweeten it. This smoothie relies on the blueberries’ natural sweetness. If you prefer a sweeter smoothie, add a dash of your favorite sweetener (I prefer liquid stevia) until it suits your taste buds.  Use more berries. Add strawberries and raspberries to make a triple berry smoothie.  Add superfoods. Add collagen powder, MCT coconut oil, or chia seeds. Or add protein. Add 1-2 scoops of your favorite protein powder. 

Storage instructions

To store: This smoothie is best enjoyed within one day. However, you can store it in the refrigerator for up to 2 days. Be sure to whisk it well before drinking in case there’s separation.  To freeze: Place the smoothie in an ice cube tray or shallow container and store it in the freezer for up to three months. When ready to enjoy, pour it into the blender and re-blend until smooth and creamy.
