What Are Overnight Oats?

For those unfamiliar with it, overnight oats are basically just a type of oatmeal porridge, but cold.

In this case, you don’t heat the milk and the oats; instead, you simply mix them together (with optional flavorings) and place it in the refrigerator the night before, allowing the oats to absorb the milk overnight.

You can then make multiple portions at once, ensuring you have a delicious breakfast ready in the fridge for two mornings. Very convenient!

Recipe Ingredients

The beauty of overnight oats is that you probably already have most of these ingredients in your pantry. No fancy equipment, no complicated steps; just wholesome goodness in a jar. While simple, always check the recipe card below for full details.

ripe bananas – you’ll need 2 medium bananas, mashed or pureed. They provide natural sweetness so no sugar is needed
Greek yogurt – I use 10% fat for extra creaminess, but any yogurt works
milk – any type of milk works. It form the basis for porridge with the oats and therefore also for overnight oats
rolled oats – old fashioned rolled oats work perfectly. If you eat gluten-free, make sure there is a ‘gluten-free certified’ label on the packaging of your oats
chia seeds – these add a lovely pudding-like texture. Another option is to add 4 tablespoons of rolled oats or 3 tablespoons of shredded coconut
vanilla extract – adds depth and warmth to the flavor. ½ tsp ground cinnamon can be used instead
blueberries – from the freezer or fresh, both work well

BAKING TIP: Divide the overnight oats between two bowls, glasses, or containers. A mason jar is ideal for this type of breakfast. Serve the blueberries just before eating.

How To Make Blueberry Banana Overnight Oats

Making these overnight oats couldn’t be easier. Start by mashing or blending the bananas until smooth, and then mix them with the rest of the ingredients (except the blueberries).

Divide between your choice of two bowls (covered), jars, or airtight containers. Refrigerate overnight.

When ready to serve, top with the blueberries and enjoy!

Storing Overnight Oats

You can store your prepared overnight oats in the refrigerator for up to 2 days. The texture will continue to thicken over time, so if you prefer a looser consistency, just stir in a splash of milk before eating.

Can I freeze these blueberry banana overnight oats?

Yes, though the texture may change slightly upon thawing. If you want to freeze them, store in freezer-safe containers for up to 1 month. Thaw overnight in the refrigerator and stir well before serving. Add fresh blueberries after thawing.

More Breakfast Recipes With Banana

These overnight oats reminded me a lot of my Easy Banana Bread Recipe. That’s because I ‘sweetened’ the overnight oats by mashing bananas into them, just like I’ve done for various other tasty breakfast recipes you can try today.

Do I need to use fresh blueberries?

Not at all! Frozen blueberries work perfectly. If you forget to thaw them overnight, just run them under warm water for a minute or microwave them briefly. Any red fruit works wonderfully as a topping.

Why is banana great for overnight oats?

Banana is a brilliant way to add natural sweetness to breakfast recipes without adding any sugar. It keeps the recipe healthy and delicious. A total win-win!

Can I skip the chia seeds?

Yes, you can replace them with 4 tablespoons of extra rolled oats or 3 tablespoons of shredded coconut. Both work wonderfully and will still give you a satisfying texture.

My overnight oats are too thick. What can I do?

If you prefer a less firm consistency, simply stir in a splash of milk before serving. You can also reduce the amount of oats or chia seeds next time, or increase the milk slightly and reduce the thick yogurt.

How do I change the flavoring of these overnight oats?

Basically, this breakfast recipe doesn’t have a very pronounced flavor, except for the banana and the vanilla extract. I always make my own vanilla extract; it’s delicious. The vanilla extract can be substituted for other flavorings such as cinnamon, cardamom, citrus zest, or cocoa powder. It is a matter of testing and experimenting to see what you like best.
