Mason jar filled with blueberry mint overnight oats for baby led weaning breakfast

Overnight oats is definitely one of my favourite breakfasts. It also happens to be one of Reuben’s favourites, as well as being perfect for baby led weaning! Overnight oats are super easy to make, only taking around 5 minutes to throw together. It’s no wonder that overnight oats are so popular at the moment!

The Health Benefits of Overnight Oats

Not only are overnight oats a really tasty breakfast for baby led weaning, they are incredibly nutritious for your little one. Overnight oats have the following benefits:

  • They are particularly high in protein compared to other grains.
  • They’re high in fibre.
  • They’re full of antioxidants.
What Will I Need?

In order to measure things accurately for recipes, I would highly recommend investing in measuring cups. Prior to owning a set of measuring cups, I used to use mugs and electric scales, but these never worked as well as I needed them to. Once I swapped to some proper measuring cups my creations improved instantly.

The issue with using normal kitchen mugs in recipes is that they all come in different shapes and sizes. If the recipe you are using includes something like an egg, then the size of the mug of flour will matter a great deal when it comes to the product you will end up with. The following measuring cups are available to purchase through Amazon:

Storage and Prep

Another thing to consider is that overnight oats need to be left in the fridge overnight, hence the name. In order to do this you will need some form of airtight container. Personally, I like to use mason jars, as they look nice, they’re super easy to clean and they do not discolour over time, unlike their plastic counterparts. Click this link, or click the image below, to go to Amazon, where you will find the following mason jars for sale:

One of the amazing things about overnight oats is that they can last for up to 5 days in an airtight container in the fridge. If you were to purchase the above mason jars, for example, you could have your little ones breakfasts organised for nearly the entire week within 5-10 minutes. How is that for time effectiveness!

The Magic Ratio

So, as for this magic ratio. It really couldn’t be any simpler! You just need to mix:

  • 1 Part Rolled Oats
  • 1 Part Milk, or milk substitute (i.e. coconut milk, almond milk etc)
  • 1 Tbsp Chia Seeds (optional)

I have used this recipe time and time again, and it always delivers. It will deliver no matter what ingredients you put in it too, so why not experiment with various flavours of overnight oats using whatever flavours you have around the house!
