This low-carb keto mixed berry smoothie is light, refreshing, and perfect for a low-carb breakfast or a mid-day snack. Plus, it is gluten-free, dairy-free, paleo, and vegan!
Similar to my other recipes with berries, such as this Blackberry Cobbler and Low-Carb Dump Cake, this keto berry smoothie is packed with protein, healthy fat, and antioxidants. And all while being keto, paleo, and dairy-free!
It's great for breakfast, a mid-day snack, or even served with coconut whipped cream for a light but refreshing dessert.
It's a rich and creamy sweet smoothie that tastes just like it came straight from a smoothie shop!

Frequently asked questions
To keep the smoothie low-carb, yes, I recommend unsweetened non-dairy milk. Cows milk usually contains high amounts of sugar (12 net carbs per cup!) making it unfit for a keto-friendly diet. I recommend using unsweetened almond, cashew, or coconut milk.
I like to use a powdered allulose/monk fruit blend because it blends beautifully and tastes just like sugar! However, since allulose and monk fruit dissolve so well, the granulated variety can also be used. I don't recommend erythritol-based blends because they don't completely dissolve and can leave an aftertaste. If using pure allulose, you will need to add a little bit extra as it's not quite as sweet. Liquid vanilla stevia can also be used but can be an acquired taste.
While berries aren't considered super low-carb, they're lower in carbs than many fruits. This means they can be consumed in small amounts (such as in this smoothie!) and still fit into a keto diet without going over your daily carb count.
Not only does avocado add healthy fats, but it makes the smoothie thick and creamy with no avocado taste detected!
Yes! While nothing quite compares to using avocado, you can replace it with coconut cream or add ice to help thicken things up.
Ingredients
For the ingredients you'll need:
- Frozen Berries - The carbs in frozen berries can vary. Be sure to choose one low in carbs. The one I use has 4.5 net carbs per ½ cup.
- Unsweetened Non-Dairy Milk (vanilla or plain) - Be sure to use unsweetened, non-dairy milk because traditional cow's milk is higher in carbs. I prefer to use vanilla unsweetened almond milk.
- Avocado - Adds healthy fats and makes the keto smoothie thick and creamy. But don't worry, you can't taste the avocado!
- Handful Of Spinach (optional) - Added nutrients.
- Cinnamon - Flavor.
- Sugar-Free Sweetener - Added to taste, I prefer a powdered monk/fruit allulose blend because it tastes just like sugar and dissolves beautifully - and no one wants a gritty smoothie!
- Pure Vanilla (not shown) - If possible, use pure vanilla, not the imitation variety.
Or here is a new variation I'm currently loving:
- Keto Vanilla Protein Powder - I recently discovered this keto vanilla protein powder, and I'm in love ❤️ If you choose this option, omit the collagen peptides and only add the pure vanilla and sweetener if needed.
Instructions
To make the berry smoothie, place all the ingredients into the jar of a blender, placing the liquid ingredients closest to the blade.
Blend on high until smooth. Taste and adjust the sweetener and serve with whipped cream and berries, if desired.
Serving suggestions
My favorite way to serve this is with unsweetened whipped cream garnished with low-carb berries and maybe a sprinkle of ground cinnamon.
Or, if you're dairy-free, top it with coconut whipped cream!
This keto smoothie is great for breakfast, a mid-day snack, or even a light dessert 😋
Storage instructions
While it can make this ahead of time, it is best fresh. Be aware that the avocado may brown a bit, so you may want to add a splash of lemon or lime juice to help reduce this.
Also, the smoothie will be thinner because the berries will no longer be frozen.
- Store: If you have any leftovers, pour them into an airtight container (ideally to the top to prevent oxidation and browning) or a freezer-safe baggie with the air pushed out. Store in the refrigerator for up to 2-3 days. If it separates, give it a quick blend before enjoying it.
- Freeze: Freeze for up to 2 months in a freezer-safe container or ice cube tray. If using an ice cube tray, freeze in the tray, then pop them out and store them in a freezer-safe container.
Substitutions and variations
- Replace the mixed berries with ⅓ cup frozen blueberries for a keto blueberry smoothie. If using ⅓ cup of blueberries instead of mixed berries, here is the nutrition info: Calories: 94 Protein: 2 Fat: 6 Carbs: 10 Fiber: 4 Net Carbs: 6
- For a keto strawberry smoothie, replace the mixed berries with frozen strawberries. If using frozen strawberries instead of mixed berries, the nutrition info is as follows: Calories: 89 Protein: 2 Fat: 6 Carbs: 9 Fiber: 4 Net Carbs: 5
- While fresh berries can be used in this keto smoothie recipe, I recommend frozen for the best texture.
- If you choose a keto-friendly vanilla protein powder, omit the vanilla and sweetener, then add as needed. Also, protein powders vary in taste. Be sure to use one that you like!
Top Tips
- When picking out avocados, they should be firm with a slight give. Also, look for avocados that still have the stem attached. If the stem is missing, it's more likely the avocados have brown spots on the inside.
- If the avocado is overripe and has brown spots inside, don't use it! It will leave a terrible aftertaste and ruin your smoothie!
- Berry mixes can vary a lot. Some have more carbs than others, so be sure to choose one with low carbs. The one I use has 4.5 net carbs per ½ cup. You can replace the berry mix with frozen strawberries or frozen blueberries.

Can you use frozen Avocado?
Cassidy says
Hi Shannon, sorry it took so long to get back to you! I've never tried frozen avocado, but I'd imagine it would work with a little extra liquid 👍
XO,
Cassidy

I think this may be one of the best tasting smoothies I have made even though it is low carb. Most low carb smoothies taste low carb, but this one does not! The avocado gives it the perfect creamy texture. Thank you for such a tasty recipe!
