I’ve been super busy at uni lately so have been heavily relying on meal prepping at weekends. And sometimes we have those mornings where staying in bed for an extra half an hour seems more appealing than getting up to cook breakfast. I feel you.

With handy recipes like these PB&J overnight oats, you can wake up late and enjoy a nutritious breakfast, because it will be ready and waiting in the fridge for you. Win-win!

What ingredients will I need to make PB&J overnight oats?

Like I said, you’ll need just 7 ingredients to make this healthy vegan breakfast.

We start with oats. I like to use porridge oats for this recipe, but you can use rolled oats if you prefer your oatmeal to have more texture. If you are coeliac, make sure to use certified gluten-free oats in this recipe.

We’ll also need some liquid for the oatmeal – I like to use a mixture of half plant-based milk and half water, but you can use just milk if you like your oats extra creamy. Any plant-based milk would work well here – soy, coconut, cashew – or why not try making your own almond milk?

To make the overnight oats extra flavoursome, I like to add a pinch of salt, some cinnamon, and some maple syrup for natural sweetness.

And of course, these wouldn’t be PB&J oats without some PB and J! You can use any peanut butter of your choosing, whether you are team smooth or chunky. Personally I like a peanut butter which is smooth and preferably 100% peanuts. In terms of the jam, I’m using my homemade berry chia seed jam, which is naturally sweetened and thickened with chia seeds!

Note that to make 3 portions as the recipe serves, you will need 1/2 a batch of my chia jam recipe.

How to make PB&J overnight oats:

Making overnight oatmeal couldn’t be easier. Simply mix all of your ingredients together in a bowl, portion out into jars/glasses, and refrigerate overnight. Job done.

We love an easy recipe like that, don’t we!

Refrigerating the oats overnight allows them to soak up the liquid and become extra creamy. This is essentially a slower version of the process that happens when we cook oatmeal on the stovetop – the heat usually speeds up the rate of absorption!

The final step is to add your toppings in the morning. Aside from peanut butter and homemade jam, I added some fresh raspberries and hemp seeds for extra protein.

Variations on this recipe:

Of course, the classic PB&J is great, but here are a few more ways to switch up your oats:

  • Swap peanut butter for almond butter or homemade pistachio almond butter
  • Try making the chia seed jam with blueberries, strawberries or cherries!
  • Add 2-3 scoops of your favourite plant-based protein powder to this recipe
  • Add chocolate. Because chocolate makes everything better.
