What Are Overnight Oats?

Overnight oats are made by using a combination of whole rolled oats, milk and yogurt. When you leave the oats chilled in the fridge overnight, the oats get a chance to absorb the liquid. This creates a soft, chewy, and creamy texture that’s very filling and eaten cold with a spoon.

Overnight oats are so easy to meal prep in advance and store in the fridge. They last a long time if you assemble them properly (I go through that in detail below). Plus, they’re full of healthy nutritious ingredients including protein and fiber that will help to increase your energy.

If you’ve ever seen overnight oats at local markets or coffee shops, they usually sell for $8-$10. But if you make them at home, they will only cost you about $1-$2. I don’t know about you, but I love a good budget-friendly breakfast!

Health Benefits Of Overnight Oats

Whole rolled oats contain fiber, protein, magnesium, potassium and omega-3 fatty acids. And soaking them overnight allows for the oats to absorb the liquid, making them easier to digest (source). Choosing healthy ingredients like plain greek yogurt (high in protein), fruit, nuts and seeds will also add nutritional benefits.

What I personally love about overnight oats is that they help to avoid a poorer food choice first thing in the morning. When you prepare them at night, you have breakfast ready to go. And if they’re in a sealed mason jar, they’re so easy to grab as you head out the door. You won’t be tempted to grab a sugary snack mid-morning because you’ll feel fuller longer, all thanks to the fiber and protein in this breakfast. So if you’re used to eating sugary cereal, or a pastry, then substituting for overnight oats is a good upgrade.

What Ingredients Do You Need For Overnight Oats Recipe?

To get the healthiest overnight oats that will provide you with more energy and avoid that mid-morning sugar crash, here are some recommendations:

  • OATS – Whole rolled oats will definitely give you the best results. I don’t recommend using instant oats because of their lower nutritional quality.
  • YOGURT – For the healthiest results, use plain yogurt (flavored yogurt will always have added sugar). You can use regular yogurt, greek yogurt, skyr yogurt, or a dairy-free option like cashew yogurt. Each kind of yogurt will give a little different consistency to the overnight oats. In general, the thicker the type of yogurt, the thicker the overnight oats will be.
  • MILK – You can use any kind of milk you prefer. I used regular milk for this recipe, but you can also use a dairy-free alternative like almond milk, cashew milk, soy milk, oat milk or hemp milk.
  • SWEETENER – I’m a big maple syrup fan, which is what I used in these recipes. However, not everyone feels the same way. You can also use honey, stevia, or 1/4 of mashed banana to sweeten your oats.
  • FLAVOR ADDITIONS – There are so many flavor additions you can try. Chocolate, peanut butter and jelly, pumpkin spice, banana raspberry and apple cinnamon recipes are all included below. Just keep reading to see how to make each of these delicious flavors.

NOTE: If you don’t like yogurt, I have a dairy free overnight oats recipe at the bottom of this post using chia seeds.

4 steps to making overnight oats. Add oats to white bowl, mix in yogurt, milk, and sweetener.

How Do You Make Overnight Oats?

This is the base recipe that we’ll be using for all of our flavors:

The overnight oats ratio is: 1/2 cup rolled oats + 1/2 cup milk + 1/3 cup yogurt + 1 Tbsp sweeter + pinch of salt = the best overnight oats

Making overnight oats is really simple and can be done in four easy steps:

  1. MIX INGREDIENTS – First, mix all the base ingredients together in a bowl. These are the rolled oats, milk, yogurt, sweetener and pinch of salt. Add in any flavor additions.
  2. POUR INTO A MASON JAR – Pour the oat mixture into an airtight container, my favorite option is an 8 oz mason jar like I use in the photos. This is not mandatory, you can use any container you have as long as you seal it with a lid or cover with plastic wrap.
  3. CHILL OVERNIGHT – Place the overnight oats in the fridge overnight to let the oats fully absorb all the liquid.
  4. SERVE WITH TOPPINGS – In the morning, add your favorite toppings including, berries, sliced banana, shredded coconut, raisins, apple slices, dark chocolate chips, nut butter and anything else you like!

How Long Do Overnight Oats Have To Sit?

Having the patience to wait for overnight oats is hard. I’ve tested these recipes after 30 minutes, 1 hour, 2 hours, 4 hours, and overnight.

I can honestly say that you need a minimum of 4 hours for the overnight oats to fully soak up the liquids and do their job. If you wait overnight they will be at their best consistency.

Oats after only 1 hour will taste sloppy and kind of gross. So even though it can be tough to wait overnight, it’s worth it.

Do I Eat Overnight Oats Cold?

Yes! Just pull them out of the fridge, grab a spoon and give a quick stir. Then dig in. The oats do not need to be heated. This might seem a little strange at first, but after you get used to it, you’ll love eating them cold!

Tips For Making The Best Overnight Oats

  • Prep ingredients the night before – Overnight oats are really easy to assemble. But you want to give the oats some time to fully soak up the milk and plain yogurt, the best time to do that is the night before.
  • Eat overnight oats cold – Most people prefer to eat their overnight oats cold – this is what makes them an easy on-the-go breakfast. This might take a bit of getting used to. So if you think that eating cold oats is just too weird, you can warm them up in the microwave. I go over that in the FAQs section.
  • Add your favorite toppings. Some toppings I recommend trying are berries, bananas, apples, oranges, nuts, hemp seeds, sunflower seeds, pumpkin seeds, sunbutter (it’s nut free), shredded coconut, raisins, and anything else you feel like experimenting with.
  • When you’re ready to eat, stir it up and enjoy. Overnight oats are pretty straightforward to eat. Take a spoon and stir them up – then take a bite. They’re wonderfully satisfying and delicious.
  • Make your overnight oats enjoyable for your own tastes. Once you try out a few recipes and learn what you like, start playing around with different combinations. Be sure to share them in the comments at the end of the post for others to see! These overnight oats are easily adaptable – try different fruits, nuts or seeds, don’t be afraid to swap any ingredients out. Or if you want to add some superfoods like chia seeds or hemp seeds, go for it.

That’s it! When you know these simple tips and tricks, you can easily make your own creations. To get you started, below are six delicious overnight oat recipes to try at home. Feel free to swap out ingredients for a different one if there’s something you like better. Like I said earlier, these oats recipes are really forgiving – it doesn’t matter what you use, they’ll still taste great.

Best Overnight Oats Recipes

Now let’s get on to the delicious flavor combinations you can make using overnight oats. Here are six recipes to get you started, along with 15 more recipes linked below.

Vanilla overnight oats are a classic simple flavor. This is the base recipe that we’ll be using for all additional flavors. This flavor tastes really great on its own with some fresh berries on top.

To make your overnight oats, simply combine all ingredients in a bowl and pour into a mason jar. Let sit in the fridge overnight, then add your favorite toppings in the morning before you eat.

Save this recipe for when you’ve got a chocolate craving! To make this chocolate pudding, you can use cacao powder. Cacao powder is healthier than cocoa powder. Yes, they look the same but they’re actually not. Cacao powder is a good source of iron, protein, magnesium, potassium and fiber.

If you’re looking for it at the grocery store, you can usually find it in the “health foods” section. You can also purchase cacao powder online.

I topped these overnight oats with shredded coconut and a few 70% dark chocolate chips, but you could also use fresh berries, nuts and seeds.

This is the classic peanut butter and jelly combo but in overnight oats! Peanut butter is added to the oat base and also drizzled on top.

I prefer to use a sugar-free strawberry jam so that I’m not adding any unnecessary sugar to the meal. You can add a dollop to the oats in the morning, and mix in just before serving. Top these oats with your favorite nuts and seeds.

The pumpkin spiced overnight oats are a classic Fall flavor. I really love this one – the vanilla oat base is mixed with pumpkin puree and pumpkin spice to create a delicious treat.

The secret to this flavor is mashed banana. It adds sweetness and a texture to the oats that can’t be beat. Top it with more sliced banana and fresh raspberries just before serving.

This is a delicious recipe that reminds me of apple pie. Cinnamon and apple are added to the oat base for the perfect combo. I like to chop the apple really small so that they don’t take up too much space in the mason jar. They are the perfect crunch when mixed with chewy oats.

Overnight Oats without Dairy

Don’t like yogourt? Lactose intolerant? No problem – these recipe combination can be used to create delicious oat base alternatives. Then just add the flavor additions to create any that you like:

Overnight oats without milk – Instead of milk you can use water. Here’s the recipe combination: 1/2 cup rolled oats + 1/2 cup milk + 1/3 cup plain yogurt and 1 Tbsp sweetener (honey or maple syrup).

Overnight oats without yogurt – If you’re not a fan of yogurt, then you can try the chia seed recipe below.

Overnight oats with chia seeds (Dairy-Free) – Instead of using yogurt, the chia seeds are used to thicken it up. Here’s the recipe combination: 1/2 cup rolled oats + 1/2 cup dairy-free milk (almond, cashew, oat, hemp, soy etc) + 2 tsp of chia seeds. Mix together and add any flavor additions. These will need to chill overnight as well.

On a side note, I really like adding chia seeds to my overnight oats! Chia pudding can sometimes be hard for me to eat because of the consistency of chia seeds. But when you mix them with oats they’re much more pleasant. 1-2 tsp of chia seeds can be added to any of these recipes, even with yogurt added as well.

Overnight Oats FAQs

Can I Eat Overnight Oats After 1 Hour?

Nope. The overnight oats won’t be ready yet. They’ll still be runny and the liquid won’t be properly absorbed into the oats. I recommend a minimum of four hours, but preferably overnight because that’s where you’re going to get the best results.

How Long Do Overnight Oats Last?

The overnight oats will last about a week in the fridge if stored in an airtight container. You can meal prep a batch of oats on Sunday night, store in the fridge and eat for breakfast throughout the week.

Can You Eat Overnight Oats Hot?

Typically overnight oats are eaten cold. But I get that this might seem strange when you’re used to eating them warm. I tested this recipe and yes, you can heat it up for about 1-2 minutes in a microwave-safe container (I recommend pyrex or glass). The oats will be super chewy and the yogurt and milk will have evaporated. It’s not my favorite way to eat overnight oats, but it still works. Truthfully though, there’s no point to making the oats this way when you could just cook them normally and add toppings afterward.

Can You Use Steel Cut Oats?

You can, but they won’t have the same consistency. Steel cut oats take longer to cook in general, they have an outer shell. So they will probably be chewier and may not fully absorb all the liquid. I haven’t tested using steel cut oats yet, but if you do let me know how it goes in the comments!

Can You Use Instant Pack Oats?

Yes you can, but I don’t recommend it. Here’s why… instant pack oats are quite different than the whole grain rolled oat version. They’re usually not the only thing included in the pack either – many have added salt, sugar and preservatives. For more energy and to avoid that mid-morning sugar crash, whole rolled oats are a better option.

How Many Calories Do Overnight Oats Have?

Each overnight oats recipe will vary depending on the toppings added, milk used, yogurt used, etc. But to give you a reference, the base recipe using rolled oats, plain greek yogurt, 2% milk, and honey will make 1-2 servings (depending on how hungry you are) and is a total of 342 calories.

How To Store Overnight Oats

The easiest way that I’ve found to make overnight oats is by using 8 oz mason jars (250 ml). This recipe will sit perfectly in this size of jar. It’s easy to seal and stack in individual-sized portions in the fridge. If you begin to love eating overnight oats regularly, then purchasing a 12 pack of these mason jars for $20 is a great (and affordable) option for storage. I also use these 8 oz mason jars for making homemade salad dressings and chia pudding. They’re really versatile.

Do Overnight Oats Have To Be In A Glass?

No definitely not. You can use any containers that you already have at home. The overnight oats should be covered while in the refrigerator. You can use an airtight container with lid or wrap the top of the container with plastic wrap.
