Instagram really is a wealth of ideas and inspiration. I had been seeing delicious filled jars with the hash tag #oiaj, so I may be a little slow but I finally figured out it meant Oats In A Jar. This is a no cook overnight breakfast made of oats primarily in a jar.

There are many variations and quantities meaning you can make it to how you like and get a great result every time.

The core ingredients are: Oats, Milk, Yoghurt, Fruit, Seeds and Nuts. Variations also include adding peanut butter to the inside of the jar, protein powder etc.

The basic concept is that you get an empty jar and fill with oats, milk (you can use soy, almond, skim whatever milk you normally drink), Greek no fat natural yoghurt, Fruit, Acia or Chia seeds (or other seeds), raw nuts.

You then place the lid on the jar and shake well to combine,

Leave in the fridge overnight.

In the morning you wake up to a creamy oat mix you can eat straight from the jar.

This breakfast meal is so convenient that you should never go without breakfast again. You can take with you and have when you get to work, have it after the gym even eat on the bus or train.

If you have made your own OATS IN A JAR please feel free to comment below with you mix.

    I have been doing this for months. Such a great idea. Mine is so simple. Oats, frozen fresh berries (work better than fresh would you believe), and greek yoghurt. About 100g of oats, the same for hoghurt, and as many berries as you like. Yum!

    I make mine with
    1/4 cup oats
    1/2 tbsp chia seeds
    1 tsp brown sugar
    1/4 cup frozen berries
    1/2 cup milk

    In a jar in the fridge overnight
    In the morning I warm the mix slightly and stir through 1tbsp nut butter (usually peanut) and 1tbsp sugar free jam.

    I make a grain free variety – 2 Tbs chia, 2 Tbs LSA, 1 Tbs pepitas, 1 Tbs sunflower seeds, 1 Tbs flaxseed, handful of cashews, 270mls ayam coconut milk. In the morning I add sultanas or fresh/frozen berries or a banana or grated Apple and cinnamon.

    As above comment – what ratio milk/yoghurt/oats please?

      Hi Jo, I never really measure but it is about 1/2 cup quick oats/museli, 1/2 cup yoghurt, 1/2 cup milk you can add frozen berries, seeds, nuts etc.

    I made it last night but mine is still runny and looks nothing like picture. I used 500ml jar, put 1/4th cup oat, rest milk with some fruit, Nutella, nuts etc. put it in fridge. My oats r quick oats…. Any ideas why it didn’t work. Thanks
