How do you fix a separated smoothie?


Smoothies are a delicious and nutritious blended drink made from fruits, vegetables, dairy products, and other ingredients. They are a great way to pack nutrients into an on-the-go breakfast or snack. However, sometimes smoothies can separate and become unappetizing. Separation occurs when the blended solids and liquids start to divide from each other. This can happen for several reasons, leaving you with an unpalatable sludge on top and thin liquid on the bottom. Luckily, there are some easy tricks to fix a separated smoothie and recombine it into something delicious again!

Why Do Smoothies Separate?

There are a few main culprits that cause smoothies to separate:

Using Too Much Liquid

One of the most common reasons for separation is adding too much liquid to your smoothie. Fruit and veggies contain natural water content, so you may not need as much extra liquid as you think. Too much almond milk, juice, water, etc. can prevent the ingredients from blending properly and bonding together. Use just enough to achieve the desired consistency.

Letting It Sit Too Long

Another cause of separation is letting your blended smoothie sit for too long. Gravity naturally pulls denser particles downward over time. If you make your smoothie in advance, the solids and liquids will start migrating apart. For best results, drink your smoothie immediately after blending.

Ingredients Don’t Bind Well

Certain ingredients are more prone to separating than others. Leafy greens, chia seeds, and flaxseed often settle out of smoothies. Proteins like yogurt, peanut butter, and protein powder can also separate out. Using too many of these ingredients without enough fruits and veggies to bind it can lead to a split smoothie.

Not Blending Thoroughly

If you don’t blend your smoothie long enough, the ingredients won’t fully break down and emulsify together. This makes it easier for separation to occur. Blend for at least 60-90 seconds to fully puree all ingredients into one cohesive liquid. Small bits of produce or “chunks” make separation more likely.

Cause of Separation How to Prevent
Too much liquid Only add as much liquid as needed for blending
Letting sit too long Drink smoothie immediately after making
Ingredients don’t bind Limit greens, seeds, proteins; use more fruits/veggies
Not blending enough Blend for at least 60-90 seconds

How to Fix a Separated Smoothie

Don’t dump that separated smoothie just yet! With a few simple tricks, you can easily re-blend a smoothie back into a delicious treat. Here are some tips for salvaging a separated smoothie:

Stir and Shake

If your smoothie only has mild separation, stirring or shaking the mixture can help recombine it. Use a spoon to stir vigorously from the bottom up until evenly mixed. You can also put the lid back on your blender bottle or jar and shake hard for 30 seconds or so. This simple fix works if the separation is minimal.

Blend Again

Pour the smoothie back into your blender and blend for another 30-60 seconds. The additional high-speed blending will whisk the separated layers back together. You may need to use a spatula to redistribute the solids that settled on the bottom for even blending.

Add Ice Cubes

Adding 2-3 ice cubes to your separated smoothie can help re-blend it. The chunks of ice will disrupt the layers, acting as a churning agent when blended again. This trick works especially well for smoothies that separated due to being too watery or juice-based.

Introduce Binders

If your smoothie is still too thin or watery after trying the above fixes, you can add extra ingredients to act as binders. 1 banana, 1 avocado, 1-2 tbsp nut butter, or 1-2 tbsp oats or chia seeds are all great options. They will add creaminess and texture to help your smoothie re-emulsify when blended again.

Dilute and Drink

If you can’t get your smoothie to recombine, don’t waste it! Scoop out the thick separated solids and enjoy them as-is or in a parfait cup. Then simply dilute the remaining liquids with a bit more nut milk or juice for a drinkable isolated beverage. Get the most out of your separated smoothie!

Separation Fix When to Use
Stirring/shaking Mild separation only
Re-blending Moderate separation
Adding ice Watery/juice-based separation
Binder ingredients Smoothie too thin after re-blending
Diluting/drinking liquids Can’t get smoothie to recombine

Tips to Prevent Smoothie Separation

Now that you know how to fix a separated smoothie, here are some handy tips to help prevent it in the first place:

  • Don’t overfill. Leave at least 1-2 inches of empty space in your blender cup or jar for proper blending room.
  • Liquid to solid ratio. Stick to around 3-4 cups fresh produce to 1 cup liquid as a guide.
  • Blend long enough. Make sure your smoothie is fully pureed with no chunks.
  • Chill ingredients. Blending chilled ingredients helps them emulsify and bind together.
  • Add binders. A banana, avocado, nut butter, or chia seeds help with texture.
  • Don’t use watery fruits. Stick to thicker fruits and veggies vs. juicy watery kinds.
  • Drink ASAP. Try your best to enjoy your smoothie immediately after blending.
  • Give it a shake. If you can’t drink it right away, shake the jar every so often.
  • Store properly. Pour smoothie into an airtight jar vs. open cup if storing.

Putting a little extra thought into your smoothie prep and ratios can prevent those annoying separation issues. But now you know what to do if it still happens anyway!

What About Using a Stabilizer?

Some people use ingredients like guar gum or xanthan gum to help stabilize and thicken blended drinks including smoothies. A tiny amount can help bind the ingredients together and prevent separation.

However, these industrial stabilizers come with some downsides:

  • Can create an unpleasant, slimy mouthfeel
  • Difficult to blend in smoothly
  • Can inhibit digestion if using too much
  • Not part of a natural, wholesome diet

For most people, following proper smoothie ratios and blending techniques negates the need for added stabilizers. But if you find your smoothies are chronically separating and other fixes aren’t working, a small amount of guar or xanthan gum may help. Start with just 1/8-1/4 tsp and increase slowly as needed.

When to Throw It Out

While you can salvage and re-blend mildly separated smoothies, at a certain point they may be beyond saving. If you notice any of the following, it’s best to cut your losses and start over:

  • Curdled look with clear whey separated out
  • Grayish watery liquid or foam at the top
  • Extremely thin, watery consistency
  • Grainy texture after re-blending
  • Noticeable changes in color or smell
  • It’s been more than 6-8 hours since blending

As a good rule of thumb, if your separated smoothie looks or smells bad, don’t risk drinking it. Toss it out. Not worth getting sick over!


While smoothie separation can be annoying and unappetizing, it doesn’t mean your blenderful is a total loss. With a few tricks like stirring, adding binders, re-blending, and diluting, you can often salvage at least part of a separated smoothie. Follow proper blending ratios, chill ingredients, and drink ASAP for best results. But even if some separation still occurs, now you know how to fix it! Just be sure to toss batches that look or smell rancid rather than risk getting sick.
