Much like my mango smoothie without banana and mango cucumber smoothie, this recipe makes the most of this delicious sweet fruit! The addition of some pantry staples makes it perfect as a mango breakfast smoothie, and it has a lovely creamy, fruity taste and texture.

We make this mango oatmeal smoothie without yogurt or banana, and use affordable freezer and pantry staples. Grab your ingredients and let's get blending!

⭐ Why this recipe is so good

Mango breakfast smoothie. Adding oats and flax makes the smoothie a little more hearty so, just like my cottage cheese smoothie, it can be a light breakfast option or snack idea.

Quick and easy. We use all easy to find ingredients, and blend it up in a few minutes.

🥭 Ingredients

individually labelled rolled oats, non-dairy milk, frozen mango, maple syrup, vanilla extract and milled flaxseed.

All the ingredients and their quantities are set out in the recipe card below.

Some notes on a few of them:

  • Mango - I suggest to use frozen mango chunks as they will give you a thick and creamy taste and texture. Plus they tend to be more affordable than fresh mango and can be used year-round!
  • Oats - You can use rolled oats, that we blitz for a few seconds, or finer quick-cook oats if you prefer. If you wish, you can pre-soak the oats, although I don't tend to do so for ease of timings. Use certified gluten free oats, if required.
  • Flax - I like to add a good pinch of milled flaxseed for the nutty taste.

📖 Swaps and variations

Swap flax for chia seeds. I love the nutty flavor that the milled ground flaxseed gives, but you can swap for chia seeds if you prefer.

🥤 How to make mango oat smoothies

Making this mango oatmeal smoothie is very simple, uses easy to find affordable ingredients and all you need is a high powered blender.

All the instructions are in the recipe card below, but these step by step photos should help guide you.

Step 1: Combine ingredients

Add the oats to your blender cup, and blend for a few seconds so they break down. Pour in the non-dairy milk, and add the frozen mango, milled flax, maple syrup and vanilla extract (if using) (image 1).

Step 2: Blend your mango oat smoothie!

Blend your smoothie, adjusting with more milk to thin, or ice to thicken, to your preference (image 2).

💭 Recipe tips and notes

Use frozen mango chunks. As well as being easy to keep in the freezer for your smoothie needs(!), they will give you a creamy thick mango oat smoothie. Fresh mango doesn't have the same consistency when blended up.

Blend the oats. It's best to blend up some rolled oats first, before adding the other ingredients. You can also use quick-cook oats which are finer in texture.

Use gluten free oats, if required. Check your ingredients labels if you have this dietary requirement.

📋 Frequently asked questions

Can you use fresh mango to make smoothies?

You can use fresh mango to make smoothies, but it will have a thinner consistency than using frozen mango and you will likely need to add more ice cubes.

What does mango score on the SIGHI list?

Mango scores 1 on the SIGHI list, with a ? as a liberator and a note, 'To be debated. Is often well tolerated'. As with all the low histamine recipes here on the blog, please only try ingredients you know you tolerate well.

Does the smoothie keep in the refrigerator?

While the smoothie will keep for up to day in the refrigerator, it will start to separate over time. I suggest my low histamine readers blend and enjoy at the time, rather than storing in the fridge to reduce histamine formation (see the food storage tips on SIGHI).

Ingredients
 
 

  • ¼ cup rolled oats gluten free, if required
  • 1.5 cups frozen mango chunks

  • 1 teaspoon maple syrup
  • ¼ teaspoon vanilla extract optional

Instructions
 

  • Add the rolled oats to your blender cup and blitz to a fine powder.
  • Pour the non-dairy milk into the blender cup, then add the frozen mango, flax or chia seeds, maple syrup and vanilla extract, if using. Blend to a thick smoothie.

Notes

  • Adjust the amount of non-dairy milk used to preference. Some of us like a thick smoothie, others thinner in consistency.

Hi, I’m Claire. After a diagnosis of MCAS I began to follow a low histamine diet, which has helped me manage my symptoms. Here I hope to show that a restrictive diet can still be full of flavourful meals, and help you enjoy being creative in the kitchen.
