Lots of no added sugar smoothie recipes use bananas for sweetness and creaminess. However, it’s easy to make a thick and creamy smoothie for low-carb diets. Today, you’ll learn how to make a blueberry smoothie keto.
I’ve used a combination of nut butter and cottage cheese to make this summer drink. A touch of stevia extract provides sweetness with no sugar. I know this combo seems weird, but please don’t judge until you try it.
Seriously, this might be my very favorite smoothie recipe out there. (Do me a favor and don’t tell the other smoothies, ok? I don't want them to get jealous. Haha)
Blueberries are actually a little higher in net carbs than some other berry options. To bring the carb count down, I’m using a combination of strawberries and blueberries. No worries though, this does not dilute the rich blueberry flavor and color at all.

📋 What are the calories, net carbs, and protein?
One serving of this low carb blueberry smoothie provides 189 calories, 9.2 grams net carbs, and 10.7 grams protein.
Why make this keto blueberry smoothie? Here are a few of my reasons:
- Vitamin C: One serving of this smoothie is an excellent source of vitamin C, an essential nutrient that supports your immune system. It’s also rich in vitamin K and potassium, nutrients that are beneficial for heart health.
- Phytonutrients: Berries are rich in colored pigments called anthocyanins that are linked to a reduced risk of certain nutrition-related chronic diseases. (As if we needed another excuse to enjoy delicious berries!)
- Fits your macros: If you are on a low carb diet, this smoothie should be a good fit for your macros. It’s very low in carbs, contains moderate protein, and is high fat.
- Gluten free: Those with celiac disease and NCGS can enjoy this blueberry low carb smoothie with no worries. It's gluten free, keto, and sugar free!
- Sweet, but not overly sweet: Many adopt the keto diet to try to get healthy and help tame their sweet tooth. This smoothie has just a little sweetness from the stevia extract. Feel free to add more or less as your tastebuds dictate.
- Frozen fruit: This smoothie recipe uses frozen berries, which tend to be less expensive than fresh berries. If berries are not in season in your area, using frozen fruits can save you a lot of money!
- Easy: This keto blueberry smoothie is low effort and high reward. It’s the sort of recipe that even people who hate cooking can love!
What do you need to make this blueberry smoothie keto recipe? Just a handful of ingredients that you can find in most major grocery stores:
- Cottage cheese
- Frozen blueberries
- Frozen strawberries
- Ice cubes
- Cold water
- Creamy almond butter
- Stevia extract
Using double cream cottage cheese makes this recipe both low carb and LCHF (low carb, high fat). Plus, the double cream (6%) cottage cheese is so, so delicious. If you like cottage cheese, I think you’ll find it’s pretty out of this world in the taste department.
I used frozen wild blueberries in this recipe because they tend to be smaller than farmed blueberries. This means they’ll break down a little quicker in the food processor. It’s fine to use bigger blueberries if that’s all you can find.
Creamy almond butter is my favorite nut butter to use here. Feel free to use crunchy almond butter for more texture in your smoothie. Peanut butter can also be used as a lower cost alternative, though it lends a stronger flavor to the smoothie.
If you don’t like nutmeg, you can skip it or use cinnamon instead. That said, I love, love, love the nutmeg here, and recommend leaving it in.
One more optional thing I like for this LCHF blueberry smoothie is some fresh blueberries. I sprinkle them on the shake and pretend they are boba. Hahaha (There’s only a few of them, so the impact on the net carb count is minimal.)
The main thing you need to make this keto blueberry smoothie is a food processor or a high-powered blender. A regular blender may not be strong enough to completely puree the ingredients.
A fun and completely optional thing to have are large-width straws. (These are also called boba straws and are the straws used for bubble tea.) This smoothie is too thick to drink using a regular straw. It’s almost thick enough to make a smoothie bowl!
🔪 How to Make Keto Blueberry Smoothie
Let’s learn how to make keto blueberry smoothies! This could not be easier.
First off, if your frozen strawberries are large, chop them up a little smaller. This will make it easier to break them down in the food processor.
Next, simply throw all of your ingredients into the food processor and blend until smooth. If some ingredients are sticking to the sides, stop the processor and scrape the sides down with a spatula. Then continue to blend.
It’s especially important to get this smoothie smooth, so you don’t end up with globs of cottage cheese or almond butter. You’re done when it’s a uniform rich violet color.
Pour your finished keto smoothies with blueberries into glasses and add wide straws. Add some fresh blueberries on top to garnish, if you wish. Drink up!
Leftover blueberry keto shake can be frozen in popsicle molds. That way, you can enjoy a sweet and creamy keto popsicle whenever the mood strikes you!

Regular dairy milk is rich in naturally occurring milk sugar (lactose), and is not the best choice for a keto diet. In lactose-free milk, the milk sugar is broken down into smaller pieces (glucose and galactose). The sugars are not removed from the milk, so lactose-free milk is still relatively high in carbohydrates.
💭 Expert Tips from a Dietitian
This is a level 2 recipe (transition and weight maintenance). This is a high-energy snack, providing enough protein and fat that a double serving could serve as a low carb breakfast. If you have a fat loss goal, I would not typically recommend drinking your calories. However, this particular low-carb smoothie has a lot of staying power from the protein and fiber-rich whole fruits.
I felt soooo satiated by two servings of this smoothie. I can’t normally say that about beverages, keto or not! I’m completely convinced that keto smoothies for weight loss can be a thing.
The cottage cheese is integral to this recipe, providing most of the filling protein. Swap the 6% cottage cheese for low-fat cottage cheese if you are looking for a lower calorie smoothie. Lowering the fat in a recipe will (generally) also lower the calories.
If you have a fat loss goal, you might want to try slipping some cottage cheese into your other smoothie recipes. Anoint yourself the king or queen of the cottage cheese smoothie for weight loss. You’ll enjoy the benefits of high-quality protein, calcium, and other essential nutrients from your secret smoothie ingredient.
Be sure to watch the video and see how quickly you can whip this one up! Woo hoo, (almost) instant gratification!
Yes, both cottage cheese and blueberries are keto friendly options. My favorite cottage cheese has 3 grams of net carbs per ½ cup (Good Culture’s Double Cream Classic Cottage Cheese). More on the blueberries in the next section!
You can have blueberries on keto. ¼ cup of wild, frozen blueberries has only 3 grams of net carbs (per Cronometer). They can fit well into most low carb diets.
Some fruits that are great choices for keto include avocado, strawberries, raspberries, and blackberries. Lemons and limes can also be used. Don’t forget that many keto-friendly vegetables are botanically considered fruits (e.g., zucchini, bell peppers, cucumbers, etc.).
