Vegan Overnight Oats (Make-Ahead Breakfast!)

This post may contain affiliate links. Please read my disclosure and privacy policy.

Overnight oats are one of the easiest make-ahead breakfasts around. I think they are especially perfect for hot summer months, when you don’t want to turn on your stove, or use your Instant Pot to make a batch of steel cut oats.

What do overnight oats taste like?

They are basically just like regular oatmeal, only cold. For some reason, enjoying cold oats sounded totally unappealing to me at first, but as it turns out, I’m glad I gave them a shot.

Not only are they easier to prepare than making warm oats in the morning, I think I actually prefer them in the summer! Think of it as cold cereal, with a softer, creamier texture.

How to Prepare Overnight Oats

Making overnight oats couldn’t be easier. You simply combine old-fashioned rolled oats and liquid, and let them sit together overnight in the fridge. In this case, I’m keeping the oats dairy-free and vegan by using almond milk, but you can swap it for any other type of milk you like.

You can add in any extras you like for texture and nutrition, including chia seeds, chopped nuts, dried fruit, coconut, and more. (If you practice food combining, try adding pumpkin or sweet potato for a starch-based meal.)

How long do overnight oats last?

If you’re using homemade almond milk, I wouldn’t make more than 3 days’ worth at a time. (Homemade almond milk doesn’t have preservatives, which I think makes it taste better, but it can spoil more quickly.) If you use a store-bought milk, your oats can keep in the fridge for up to 5 days.

Can you make overnight oats made with water?

I tested overnight oats using both almond milk and water, and both “worked” in the sense that the oats became tender overnight. However, the almond milk makes the oats MUCH creamier, and I found that much more enjoyable. Ultimately, the choice is up to you, so feel free to experiment.

Can overnight oats be heated?

If you’d prefer to eat your overnight oats warm, you can certainly heat them up on the stove (or even in a mini crockpot if you can have one at work!). Since they are already tender, you simply need to warm them up, so it shouldn’t take long regardless of the method of heating you use.

However you serve them, I hope you’ll enjoy this easy gluten-free & vegan breakfast idea!

Add-In Ideas


  • If you want to prepare 4 individual servings, you'll need 4 separate jars. (I use these 14-ounce jars with lids)
  • In each jar, add 1/2 cup of rolled oats and 1/2 cup of almond milk. Stir to combine, then add in any other add-ins you like. I love to add 1 teaspoon each of chia seeds and maple syrup to each jar. (Note: Wait to add any fresh fruit until just before serving, so that the fruit doesn't get soggy.)
  • Cover the jars with an airtight lid and place them in the fridge to soak overnight. The oats will absorb the liquid and become tender, ready to serve by morning.
  • To serve, simply grab a jar from the fridge and stir the oats with a spoon. You can add any other toppings you like at this point, such as fresh fruit, nuts, dried fruit, nut butter, and more.

Recipe Notes:

I’ve only tested this recipe using old-fashioned rolled oats, but I assume quick-cooking oats would work as well. I think steel cut oats would be chewier, so I stick to cooking those in my Instant Pot in batches for an alternate make-ahead option.

Reader Feedback: Have you made overnight oats before? I imagine the flavor combinations are endless!

I have overnight oats so much for breakfast, and my toddler loves it too! But i don’t normally put in chia seeds, so I will have to try that!


I’m definitely going to try this with steel cut oats adding sweet potato as a starch meal.


Love overnight oats! My fave is organic oats soaked in coconut-rice milk sweetened with dates and topped with blueberries and peanut butter ๐Ÿ˜๐Ÿ˜๐Ÿ˜

    Michele Quinn

    Wow! Can you supply that recipe? I would love to try that.


I’ve heard (somewhere) to soak the oats overnight in water, drain, and then add your almond milk – what would be the reason for that vs your recipe above? Thanks!

    Megan Gilmore

    Hmm… that sounds like an attempt to reduce phytic acid. I’ve read somewhere that soaking only reduces it by less than 25%, so I’m not sure it’s worth the hassle to drain them in the morning, but I think adding an acid, like lemon juice or raw apple cider vinegar might be an easy way to neutralize it.

      Michele Quinn

      Can I leave out the maple syrup or will that be gross?


Yum, I am looking forward to trying these overnight oats this week!

Lewis Johnson

I love making overnight oats. It’s so good.




I am confused. If you are food combining, how can you mix the oats and fruit?

    Megan Gilmore

    If you practice food combining, you won’t mix the fruit and oats. But, you could eat the fruit 30 minutes beforehand and then the oatmeal if you like! Not all of the recipes on my website are properly combined (since I don’t eat that way all the time), but the recipes in my first two books are clearly labeled and have week-long properly combined meal plans, if you need more specific guidance!

Could you make this with frozen fruit?


I have been reading about preparing overnight oats at room temperature or warmer with something like yogurt or kefir to help with fermentation of the phytic acid. Have you tired this? Do you think it makes much of a difference with digestion?
I love this recipe and want to maximize nutrition! Thank you for all your amazing recipes and wonderful information!
