Easy Basic Overnight Oats

GF VG

Here’s everything you need to know about overnight oats — the best basic recipe, the proper ratio, plus 20 different variations. Overnight oats are delicious, so easy to make and perfect for meal prep.   

Do you love oatmeal, but swear it off during the hot summer months because the thought of eating a steamy bowl of oatmeal makes you sweat just thinking about it! I feel ya and I have a solution… overnight oats!

I am a HUGE fan of warm oatmeal (especially baked oatmeal), but overnight oats have held a special place in my heart since I discovered them in 2009. They’re so easy to prepare and the combinations of flavors are truly endless. I love that I can prep everything the night before and wake up to a delicious breakfast. I’ve experimented with so many different flavors, but in this post I want to answer all your overnight oats questions and share my basic recipe.

Ingredients Needed Overnight Oats

  1. Old-fashioned rolled oats – Old-fashioned rolled oats are a must for overnight oats. They soak up the liquid overnight, which gives you a lovely creamy texture. Instant, quick-cooking and steel cut oats don’t work because they don’t absorb the liquid in the same way that rolled oats do.
  2. Milk – You can make overnight oats with any type of milk you prefer. I personally like non-diary options and usually use unsweetened almond milk for my overnight oats.
  3. Yogurt – Yogurt gives overnight oats an extra creamy texture while adding a bit of protein. I personally like using plain Greek yogurt since it’s the highest in protein and lowest in sugar. To make vegan or dairy-free overnight oats you can use a non-dairy yogurt or skip the yogurt all together and use additional milk.
  4. Chia seeds – Chia seeds are optional, but I love them because they add a bit of fiber, protein and omega-3 fatty acids and they help absorb some of the liquid which gives the oats a thicker consistency.
  5. Add-ins + toppings – Here’s where you can get creative. Just like with regular oatmeal, there are some classic add-ins like vanilla extract, ground cinnamon, maple syrup (or honey) and a pinch of sea salt that really elevate the flavor and make overnight oats super tasty.

Overnight Oats Ratio

The base “recipe” for overnight oats is so simple! The hardest part is getting the right ratio of oats to liquid, but if you follow my recipes you’ll be set!

I aim for a 1:1 ratio of rolled oats to milk, plus half as much yogurt. So for 1 cup of oats, I use 1 cup of milk + 1/2 cup of yogurt (or an additional 1/2 cup of milk). For this recipe, I’m skipping the yogurt and using the extra milk. This seems to give the oats the perfect consistency, not too thick, but not soupy. For the liquid, I usually go for non-dairy milk like almond milk, but you can use whatever milk you have on hand and if you really want to experiment you can try using different liquids like fruit juice.

Get Creative!

Like I said, you can mix in different ingredients or add toppings to really take your overnight oats to the next level. Below I’m sharing my basic overnight oats recipe, plus variations for chocolate chip overnight oats, peanut butter overnight oats and berry overnight oats. Of course, this is only the tip of the iceberg… scroll down to the bottom of this post to find links to over 20 different recipes!

And just to get your creative juices flowing… here are some fun mix-ins and toppings to add to your base overnight oats recipe:

  • Fruit – you can’t go wrong with bananas and berries, but almost any fruit will work
  • Nut butter – I use peanut butter and almond butter most often, but any and all nut/seed butters are great including coconut butter
  • Nuts and seeds – almonds, peanuts, pecans, walnuts, sunflower seeds, coconut, hazelnuts, pumpkin seeds… you’re options here are endless
  • Granola – I’m a granola girl and love adding crunchy granola on my overnight oats. If you’re looking for homemade granola recipes, I highly recommend my hemp granola or this coconut granola
  • Protein –  a dollop of Greek yogurt or cottage cheese will add a good amount of protein
  • Chocolate – I’m all about sneaking a little chocolate into my breakfast. I like to use Lily’s chocolate chips because they’re low in sugar and carbs, but any chocolate chips or even a chopped chocolate bar will work

Mix, Soak Overnight and Enjoy!

Once you have all your ingredients mixed together, simply cover and put in the fridge the oats in the fridge to soak overnight. I personally like to use wide mouth 16 oz mason jars for storing my overnight oats but any airtight container will work.

The next morning, grab your overnight oats from the fridge, give the mixture a big stir and top with your favorite toppings. At this point you can simply dig right in as overnight oats are meant to be eaten cold. See my note below if you’re not keen on eating cold oats.

How Long Do Overnight Oats Need to Soak?

Given the name, you’d assume overnight oats need to soak overnight, but you can actually make them in 2-4 hours if you’re in a rush. While it does take some time for the oats to absorb the liquid, they don’t necessarily have to be soaked overnight.

I recommend at least 8 hours for true overnight oats, but there have been mornings where I decide I want overnight oats for breakfast even though I didn’t prep them the night before. When this happens I’ll make them the morning of and let the oats soak for just 2-4 hours. With this quick soak, they’re not as soft as overnight oats that have soaked longer and they’re a bit more liquidy, but they’re still delicious.

How Long Do Overnight Oats Stay Fresh?

When stored in an airtight container in the fridge overnight oats should last for up to 5 days. They will soften more the longer they sit so I find they’re best on days 1-3, but they’re still safe to eat on days 4 and 5. With this said, overnight oats are great for meal prep. Feel free to make a whole batch for the week on Sunday. I like prepping them in wide mouth 16 oz mason jars.

Can You Eat Them Hot?

Short answer, yes! You can definitely warm up overnight oats, but the whole point of overnight oats is to eat them cold like muesli. Even if you think cold oats sound strange, I recommend giving it shot before you write them off. Of course, if you simply can’t do the cold oats you can always heat them up. Just pop the overnights oats in your microwave, cooking in 30 second increments until the oats are warm throughout and enjoy.

Can Overnight Oats Help You Lose Weight?

Let me start by saying, oats are not the key to weight loss, but oatmeal is a great option when you’re trying to eat healthy and lose weight! It is packed with fiber, but I recommend pairing it with protein to prevent blood sugar spikes. I love mixing in protein powder or Greek yogurt right to my overnight oats.

If you’re looking to keep your sugar consumption down you can always omit the maple syrup/honey from the overnight oats recipes or use a sugar alternative like stevia or monk fruit to sweeten the oats. You’ll just have to play around with how much to add based on your preference.

      Hi there! Is one serving about 2cups/16 oz? I like to make a big batch in a large bowl for the family and trying to sort out what a serving size actually is. Thank you!

        One serving is a little over 1 cup (I would say closer to 1 1/4).
