Why use frozen mango in overnight oats?

But why should you use frozen mango in overnight oats? Well for one thing it is cheaper than buying and using fresh fruit in overnight oats and is still just as nutritious.

What are overnight oats?

Overnight oats are basically just your regular breakfast oats that have been soaked overnight in liquid such as milk or vegan milk alternatives such as almond milk or oat milk.

Tip: one of our favorite milk types to use with mango overnight oats is coconut!

By leaving the oats to soak overnight in the liquid, they become soft while still keeping all of their nutritional value while the liquid becomes thicker and creamier in the process.

However the water content of frozen oats will also go into this soaking mixture and affect consistency.

How to use Frozen Fruit in Overnight Oats?

If you are using frozen fruit in overnight oats, then you will need to reduce the liquid content slightly compared to overnight oats with fresh fruit. This is because more fruit juice and water will be released into the mixture with frozen fruit versus fresh fruit.

Alternatively, you can add some chia seeds into the mixture which will help thicken the overnight oats.

Also it is worth noting that frozen mango is firmer than when you make frozen berries overnight oats. Therefore to have the mango fully thawed and softened into the mixture you will need to leave this overnight rather than just a few hours.

Substitutions & Variations

Want to try something different? Here are some options.

  • Yogurt – you can use flavored yogurt, vanilla yogurt or even Greek Yogurt with honey. However flavored yogurts are sweeter so you may need to reduce or eliminate the maple syrup from this recipe. We recommend trying before adding and then adding maple syrup slowly to taste.
  • Vegan – instead of dairy yogurt and milk use vegan alternatives such as almond, coconut or oat to make a delicious vegan alternative.
  • Coconut Flakes – Mango and coconut are a classic combination. For really tropical overnight oats top the mixture with coconut flakes.
  • Berries – if frozen mango isn’t your thing you could add in frozen mangos instead.
  • Fresh Mango – Fresh fruit are equally tasty to frozen and can be substituted into this recipe with a tablespoon more milk to get the right consistency.

You could also add in any of the below ingredients for a flavor variation depending on your palette.

  • Coconut Flakes
  • Honey
  • Nuts
  • Caramel


Store in fridge and consume within 3 days for optimal texture.

If you leave the oats for the full 3 days you may find you need to add an extra tablespoon of yogurt into the mixture to get the right consistency.

These ingredients don’t stand up well to re-freezing.

We recommend leaving these oats overnight for best results, it is in the name after all. While on some of our other overnight oats recipes you can leave the oats for as little as two hours. However as mango is firmer than other fruit like berries, it really does need to be left for longer.

Best Jars for Overnight Oats

8 oz glass mason jars are recommended for this recipe. However any glass container will work.

Alternatively you could also use tupperware to store in the fridge and portion out in the morning however I never think this looks quite as nice as serving in the glass jar.
