How we came up with this recipe

I first created my Baked Oats recipe a while back, and it was so well received that I thought I would share a spin-off that was quicker and easier to prepare. 

I love oats in the morning, and prep-ahead breakfasts are fantastic for families, so I decided to give this one a try.

I have to say, I had lots of fun trying different topping options with this! (See below for some ideas.)

Ingredients for Overnight Oats in a jar

  • Oats – Either jumbo oats or rolled oats is fine
  • Yoghurt – I use low fat Greek  because it’s what we have in the house. Any yoghurt works though (if it’s very thick though, be aware you may need more milk)
  • Milk – Your milk of choice

Two jars with lids on, inside is overnight oats mixtures. The one of the left says 'night before'. The one on the left says 'morning after' to show the comparison.

How to make Overnight Oats

  1. For basic overnight oats, mix the ingredients together and store in the fridge until morning. 
  2. Add your additional toppings either the night before or before you eat.
  3. Stir well before serving.


Here are 5 different ideas that I tried out myself, but go crazy and try whatever takes your fancy! For example, jams, purees, frozen fruit, nuts, spices, seeds, and nut butters work well. 

I do think this recipe benefits from having at least a little sweetness added, such as maple syrup, honey or Nutella (!) But it’s down to personal preference, so you decide.

When to add the toppings

You can add these either the night before OR in the morning, just before you’re ready to eat.

I tend to add them in the morning, as the oats will last up to 3 days without the toppings.

If you want to save time, and plan to eat them after just one night in the fridge, adding the night before is fine.


  • Vegan overnight oats – Make this dairy-free by using a cow’s milk substitute (like almond or oat) and a vegan yoghurt


In the fridge You can store these without toppings for up to 3 days.

In the freezer You can freeze overnight oats! The best way to do this is to make them up in containers (without toppings), then freeze, and thaw overnight in the fridge when you want to eat them.

Top tips

Overnight oats ratio

To make one portion, add 40g of oats, 50g of yoghurt and 100ml of milk. 

Type of container

Any container that you can put a lid or covering on works well. Just be sure it has enough space to allow for the oats to plump up and to add your toppings.

I really like using these Kilner jars as they have a wide top to be able to reach your spoon in easily AND they have liquid measurements on the side so you can just pour milk straight in without measuring in a jug. YESSS!

Which type of oats

In the photo below I’ve used both whole (jumbo oats) and also rolled oats. As you can see, there’s hardly any difference between them after a night in the fridge. 

They look slightly different but the texture when eating them is almost identical. So, simply put, use whichever you have in the cupboard!

Are overnight oats healthy?

Yes! Where do I start with how much goodness is in oats? They’re rich in fibre, protein, antioxidants, vitamins and minerals. 

They help protect against heart disease and diabetes, reduce cholesterol, improve insulin sensitivity, lower blood sugar and help metabolism. They’re also filling, so reduce the likelihood of unhealthy snacking.

What a way to start the day!

Can I heat overnight oats up?

Yes. Just pop into the microwave for 30 seconds at a time, stirring well between bursts of heating.

How long will overnight oats keep in the fridge?

Without the flavours/toppings, they will be fine for 3 days after you make them.

Some people say longer, but I think they do go a bit of a strange texture if left for longer.

Help! My overnight oats are too thick!

The first time you make them is a bit of trial and error, but you’ll get to know the right consistency for you and your own ingredients. 

Add a little more milk and stir well if it’s too thick. Equally, if too runny, next time add less.

Can I make more than one portion at the same time?

Yes! You can make a bigger batch according to the amount of people you’re serving.

Make sure you use a big enough container, like a bowl, and allow plenty of room for expanding oats and toppings.

    Absolutely love these overnight oats. Sometimes I make them the night before and sometimes in the morning. Jaffa cake is definitely my favourite!

  2. 5 stars
    Really great recipe 😍. We have loved trying all the flavours and the apple pie one is my favourite, but my boys like the Nutella ones best, although we found 1tbsp Nutella too much and added less.
    Love all your recipes, I’ve tried lots of them and have never been disappointed. Thank you for making cooking exciting.
