How to make overnight oats – the perfect healthy breakfast to prep at the start of the week and eat all week long plus our 6 favourite flavour ideas!
Have you ever made overnight oats before? If you are a breakfast person (like me) but mornings are just a blur of trying to get kids ready and get out the door, then you will love overnight oats!
They are the perfect breakfast to make ahead of time and store in the fridge, ready to eat when you are.
I make them in jars that they can be eaten straight out of – less dishes, they can be put in your bag to take in the car and eating breakfast out of a jar seems to be a real novelty for Sadie, who isn’t always a big breakfast eater.
How do you make overnight oats?
Overnight oats are the most simple thing to make! My base recipe for overnight oats includes the following ingredients:
- Rolled oats – I use regular rolled oats. You could also make them with wholegrain oats but I don’t think they will be as creamy.
- Chia seeds – optional but they are a great nutritional boost and also helps make the oats thick and creamy.
- Salt – just a pinch and it makes all the difference to the flavour of the oats!
- Milk – I use regular milk but if you need to you can use coconut, almond or any other plant based milk that you drink.
- Greek yoghurt – I use unsweetened Greek yoghurt as it’s most often what we have. It also adds extra protein and no sugar so it’s a healthier alternative and makes the oats super thick and creamy.
- Maple syrup – just a couple of teaspoons of maple syrup makes these oats so delicious! You don’t have to add maple syrup but I find that the oats are not that exciting without it. Use more or less depending on your taste preference and what other mix ins you are adding.
- Vanilla extract – this is the best way to add a flavour boost and it’s what makes the base recipe delicious without even adding any mix ins!
For all overnight oat recipes, start with the base vanilla recipe and then add the following mix ins
- Tropical Overnight Oats: 1/4 cup pineapple and mango pieces (fresh or frozen) + 2 TBSP dessicated coconut
- Chocolate Peanut Butter Overnight Oats: 2 TBSP cocoa powder + 1 TBSP peanut butter
- Mixed Berry Overnight Oats: 1/2 cup mixed berries (fresh or frozen)
- Banana Chocolate Chip Overnight Oats: 1/2 banana, chopped into pieces or mashed + 1 TBSP chocolate chips
- Coffee Overnight Oats: 1 teaspoon instant coffee powder + 1 TBSP chocolate chips (optional but delicious!)
What are overnight oats?
Overnight oats are almost a cross between porridge or oatmeal and muesli. They are made from mostly oats but are mixed up with milk, yoghurt and a few other goodies and left in the fridge overnight. The oats soak up the milk and you are left with a creamy, delicious breakfast.
Do you eat them hot or cold?
They are intended to be eaten cold, although if you prefered, you could definitely heat them in the microwave or on the stove.
Can I use plant based milk instead of regular?
Absolutely! I use regular milk and yoghurt as that’s what we eat but if you have allergies or intolerances, use whatever milk you drink – coconut, almond, soy or whatever! Same with the yoghurt. Coconut milk would be the perfect milk to use in the tropical flavoured oats!
Can I use honey instead of maple syrup?
Yes but make sure the honey is quite runny so that it mixes in well with the other ingredients.
Can I use frozen fruit?
Yes! I often use frozen mango, pineapple and berries in my overnight oats. That way, it’s even less prep time as you just take the fruit straight out of the freezer bag and put it into the jar!
How long do they last in the fridge for?
I work on keeping them for 5 days. I make several jars on a Sunday night and they are good until Thursday or Friday.
