Why you’ll love this recipe:

My Blueberry Overnight Oats not only taste incredible, but they are one of the easiest recipes to prepare. It takes just a few minutes of preparation the night before – simply mix your ingredients together in a bowl or jars and pop them into the fridge.

In the morning, when you’re ready to serve, top the oats with Greek yoghurt and lots of fresh blueberries.

You will love these Blueberry Overnight Oats because:

They require minimal preparation – the ingredients base for the oats are mixed together and placed in the refrigerator!
The quantities can easily be adjusted to your needs – the written recipe serves two, but can easily be halved or doubled!
They are ideal for meal prep. Lasting for three days in the fridge, you can make a start on your breakfast preparation for the week ahead.
Overnight oats are so versatile – we top our oats with Greek yoghurt and fresh blueberries, but you could also use coconut yoghurt, a swirl of blueberry chia jam and chopped nuts.

Ingredients in this recipe:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

Blueberries – fresh or frozen blueberries can be used here. If using frozen blueberries, allow them to defrost in the fridge overnight before topping the oats.

Old Fashioned Rolled Oats – the best oats for this recipe. Although steel-cut oats and quick-cooking oats can be used in overnight oats recipes, they may require a different ratio of liquid.

Milk – I like to use almond or oat milk, but soy milk works just fine as does dairy milk – use a milk of your preference.

Chia seeds – helps give the oats a nice thick texture, and also add some extra fibre. Black or white chia seeds are fine to use in this recipe.

Maple syrup – for a hint of extra sweetness. You could also use honey.

Vanilla – use a good quality vanilla extract that is naturally produced from the vanilla bean and not synthetically flavoured.

Lemon zest – adds freshness and brightness to the overnight oats.

Greek yoghurt – when serving, we like to top the oats with Greek yoghurt. You could also use coconut yoghurt, or skip the yoghurt altogether if you prefer.

Refrigerate your overnight oats mixture for at least 6 hours. I make mine just before bed and they are perfect in the morning!

There are different rules regarding this, depending on where you live in the world. For Australian residents, Coeliac Australia provides a great resource on this topic. Always be sure to read the labels and consult with a health professional if you are unsure.

Variations and substitutions:

Blueberries – I have used fresh blueberries, but frozen ones work perfectly so this recipe can be enjoyed all year round. Defrost your berries in the fridge overnight.

Banana – some mashed banana is a delicious addition.

Serving suggestions:

Mashed raspberries, like our Raspberry Overnight Oats.
