Want to know how to make a smoothie thicker? Maybe you’ve blended all your ingredients together but things are looking a bit liquidy. Or you love the thick consistency of smoothie bowls and want to make something spoonable instead of drinkable. 

In this article – we share 10 ways to make your smoothie thicker so you can enjoy the perfect consistency with zero fuss.

What Makes a Smoothie Thick?

Creating a thick smoothie is about balancing the ratio of ingredients perfectly. It sounds simple but is actually surprisingly tricky. Different fruits and vegetables have varying levels of water content so it can be hard to judge the right amounts.

A thick smoothie requires plenty of your base ingredient – banana, mango, avocado, or anything similarly dense. You’ll also need to use minimal liquid – enough to bind everything together but not so much that it goes watery.

How To Make a Smoothie Thicker

There are lots of ways to thicken a smoothie, even with limited ingredients. Some of them are about the preparation whereas others can help you rescue a thin, liquidy situation. Here are 10 ways to make your smoothie thicker…

  1. Limit the liquid
  2. Don’t blend it for long 
  3. Add more of the base 
  4. Thicken with oats
  5. Include chia seeds
  6. Add protein powder
  7. Blitz some avocado
  8. Use frozen fruit
  9. Add nut butter
  10. Leave it to separate 

Whether you’re looking to thicken up your smoothie bowl, protein shake, or classic fruit smoothie, these tips will help. Let’s look at each of them in more detail…

#1 – Limit the Liquid

For a really thick fruit smoothie, add your liquid a little at a time. This will prevent you from accidentally adding too much and making it watery. 

#2 – Don’t Blend It For Long

The longer you blend it, the more the ingredients are broken down into smaller parts, resulting in a thinner consistency. Blending it for a few short bursts will help you achieve a thicker smoothie.

#3 – Add More Of The Base Ingredient

If you find yourself with a liquidy (that’s a word right?) smoothie after you’ve blended it, try adding more of your base ingredient. This should thicken it up in no time.

#4 – Thicken With Oats

Adding oats will also thicken your smoothie and make it more filling too. It’ll also add some slow-release carbs to keep your energy levels up. Traditional porridge oats or instant oats are fine.

#5 – Include Chia Seeds

Chia seeds have a magical* thickening property so are a fantastic add-in to any smoothie. In fact, they can absorb up to 10x their weight in liquid to form a gel! Plus, they’re packed with fibre, calcium, and omega-3 fatty acids too.

*The nutritionist in me feels compelled to clarify that it’s probably more scientific than magical.

#6 – Add Protein Powder

Adding protein powder can also make your smoothie a bit thicker. Some brands of powder have a thickening agent which helps them to form delicious workout shakes. Plus, protein powder can add an extra layer of flavour (call us boring but we think vanilla rules).

#7 – Blitz Some Avocado

Avocado is super-dense so will instantly thicken a smoothie. It also has a pretty neutral taste so won’t overpower the flavour of other ingredients.

#8 – Use Frozen Fruit

Frozen fruit creates thicker smoothies than fresh produce. You can buy ready-made frozen fruit packs from most supermarkets so there’s no need to make your own. We usually have a stash of banana, pineapple and berries in the freezer at all times (frozen banana thickens up smoothies particularly well).

#9 – Add Nut Butter

Peanut butter is our go-to for thickening purposes. You know the way PB glues your mouth together? Well, it can perform the same miracle for your smoothies. Feel free to experiment with other flavours of nut butter too.

#10 – Leave It To Separate

Our last tip involves a bit of patience. You’ll need to leave the smoothie for a while so that it separates. Then pour away the liquid that settles on top and give it a very quick blitz to mix it all again thoroughly.

Following these tips will ensure you enjoy super-thick and filling smoothies no matter what ingredients you have to hand.
