How to make your frozen smoothie thicker

Trying to figure out how to make your frozen smoothie thicker? You're in luck! Below we run through the many ways you can make your frozen smoothies thicker. And to be honest, this gives you another excuse to experiment and drink more smoothies during the week!

You love your smoothies (we do too!), but sometimes you just want them to be a little less liquid and slightly more solid.

You know, something that you can really chew on and sink your teeth into.

Something that feels a bit more substantial and keeps you fuller for longer.

Is this you?

If so, read on, we’re going to look at some delicious and nutritious ways to make your frozen smoothie thicker.

How to thicken a smoothie

The basic premise behind thickening a smoothie is to increase the ratio of solids (foods) compared to the liquids.

That makes sense doesn’t it?

And where is a good place to start with thickening up your smoothie, your choice of liquid.

Your choice of liquid

On top of just having less liquid, your choice of liquid can change the texture of your smoothie too.

When compared to water, plant milks are much thicker (and tastier usually too!).

The great thing about them is how easy they are to make and if you’re making them yourself you can control how thick they are.

So you can buy your own plant based milk or, if you’re looking at making your own, we have some steps on how you can here, make your own plant based milk.

If you’re looking for more thickness, it’s all about increasing the amount of the base ingredient to make the plant based milk thicker in the recipe.

The foods you choose

Part two of increasing the ratio is the foods you choose to add to your smoothie.

Choosing foods that are more solid, without as much water are going to help thicken up your smoothie.

For example, including things like cucumber or oranges are going to taste great and provide you with some vitamins and minerals but won’t do much for thickening your smoothie.

You need to find and experiment with the food ingredients we have listed for you below.

Adding more Super Cubes

The easiest way of all we’ve found to thicken smoothies is to add a few more of our favourite Super Cubes smoothie cubes into the concoction.

If it’s looking a bit watery and you haven’t got any more time to prepare ingredients, it’s as easy as popping in another cube to thicken up the mix and also help to boost the nutrient density too.

Chia seeds

Add in chia seeds, stir them in to your smoothie and let them sit.

In 10 minutes they should start to gelatinise, though leaving them for longer will cause them to gelatinise more.

Alternatively, if you can’t be bothered waiting, you can just blend the chia seeds straight in to your smoothie.

Chia seeds are a great source of plant-based omegas and calcium.

Plus, they’re really yummy, and a great conversation starter at the office, “Hey, how are you, are those chia seeds in your teeth by chance? They are, that’s fantastic”.

Nuts, nut butters and seeds

What’s your favourite nut to add into a smoothie?

Here in the Super Cubes office, cashews seem to rule, though we also love our pecan and macadamia nut butters.

Are you a fan of the basics and really can’t go past your peanut butter?

Or a bit nuttier and love your almond, brazil nut and cashew combo?

Sometimes if you’re feeling a bit Hulk-like, you can go for adding in pumpkin seeds.

Whatever the case, adding in your favourite nuts or seeds are a fantastic way to add some thickness, creaminess and loads of flavour to your smoothies.


Go for Greek

If you’re a dairy lover and tolerate it well, you could make a simple swap to thicken your smoothie.

Swap your plant based milk out for some Greek yoghurt.

It contains some probiotics and protein, without compromising on the calcium levels too.

So a very easy way to thicken up your frozen smoothies, although you may have to watch your calories if you’re following a nutrition plan and adding Greek yoghurt constantly.


Forget about that home loan, we want avocado smoothies!

Now, we don’t know many people that don’t love avocado, but there's one person in the Super Cubes office that was lucky enough to grow up with a brother who didn’t eat it, meaning they never had to share.

How lucky is that!

Adding avocado to your frozen smoothie is as easy as popping in some into your blender and blending.

It’s absolutely delicious and creamy by itself, so imagine what is like adding it to your best smoothie recipe!

If you needed some more reasons on why you should add avocado to smoothies, it’s packed with the antioxidant Vitamin E, the carotenoid lutein, full of heart healthy fats and is actually quite a good source of fibre too.

Bundle this all together and it’s potentially an eyesight-saving, heart-strengthening, skin-improving bundle of joy.


Let’s not forget about the humble old banana here.

Keeping a few bananas on hand in your fruit bowl or some ripe ones in your freezer is yet another easy way to thicken your smoothie.

Plus, bananas taste awesome and contain some potassium, which most of us could do with more of. 

Pumpkin or Sweet Potato

To wrap it up, let’s not forget about these carotenoid rich superstars!

On top of this, pumpkin and sweet potatoes also contain some B vitamins, vitamin C, fibre and potassium.

Can you think of anything more nourishing than a sweet potato?

Seriously, can you?

Steam, boil or cook these before blending because if your try to add them in raw, well no, it just doesn’t work.

Thicken your smoothies up

During winter in particular, we know a lot of people are going to be craving a bit more nourishment and filling foods.

Thick smoothies are a fantastic way to satisfy this need, especially when you’re pumping it full of extra ingredients like avocado, sweet potato and nut butters.

Also having frozen smoothies or normal smoothies as a whole during winter makes sense, packing in that extra nutrients to help support your immune system has to be good for you in the end.

Which ingredients stick out for you in the above?

Do you like a thin liquid soup-like smoothie or do you much prefer a solid, dense and thick smoothie?
