Is overnight soaked oats healthy?

Rolled oats have so many great health benefits as they contain high-quality protein, vitamins, minerals, and antioxidants. They can lower cholesterol levels and can improve blood sugar control. It will also help in digestion and make you feel full longer! And since the main ingredient of overnight oats are…oats (duh!), you can get all these nutritional benefits by eating overnight oats!

I would however go easy on the toppings, especially in this Oreo overnight oats. I think we can all agree that Oreos are not the healthiest food so don’t go overboard there!

If you want a super healthy overnight oats recipe, try this Frozen Fruit Overnight Oats where I use mixed berries for the toppings instead of Oreos! Or check out my fiber-packed Flax Seed Pudding (3 Tasty Variations!), which also happens to be super popular on YouTube!

Are overnight oats as healthy as oatmeal?

Ingredients-wise, they are the same so technically, yes, overnight oats are as healthy as oatmeal. However, of course this depends on what you add as the toppings. If we assume that you only use oats and milk as the base, then overnight oats are indeed as healthy as oatmeal.

Ingredients

Just 3 ingredients are all you need to make this Oreo/cookies and cream overnight oats.

labelld rolled oats, milk, and oreo in small white bowls
  • Rolled oats: Packed with fiber, vitamins, and minerals. The good old-fashioned rolled oats have all the good stuff!
  • Plant-based milk: Makes for that creamy texture in these overnight oats. I used oat milk but any kind of plant-based milk will work. Think of almond milk, coconut milk, rice milk, soy milk, etc!
  • Oreo: The classic biscuits that everybody loves!

Step-by-step Instructions

Crush: Crush 2 of the Oreos into smaller pieces. I like to break 1 Oreo into 4-8 parts, each about 2 cm in length. You can just do it by hand, or chop it using a knife.

Mix: Mix in the rolled oats and 2 Oreo biscuits, then add the milk.

Chill: Let it sit in the fridge for at least 2 hours, or overnight.

Serve: Before serving, add 1 more crushed Oreo as a topping and enjoy these cookies and cream overnight oats!

Toppings Suggestions

The Oreo cookies/biscuits already serve as toppings but if you want more, below are some tasty options!

  • nuts (almonds, hazelnuts, macadamia, whatever nuts you have on hand!)
  • plant-based yogurt
  • seeds (sunflower seeds, pumpkin seeds, hemp seeds, chia seeds, flax seeds)
  • cacao nibs
  • Nutella (make your own Nutella by following my Vegan Nutella recipe here!)
  • even more Oreos!

To serve, you can either eat it cold or warm. If you want it warm, just microwave it for about 30 seconds until it is warm enough for your liking! Be sure to only add the crushed Oreo biscuits as toppings after microwaving so that they won’t get soggy!

Storage, Meal Prep, and Freezing Instructions

Storage: Store this in the fridge for up to 5 days.

Meal prep: You can make this recipe ahead of time for up to 5 days.

However, if you want them fresh, I recommend portioning out the dry ingredients (the rolled oats and the crushed Oreos) in small jars. Then only pour the milk the night before you want to consume them.

Freezing: You can freeze this recipe for up to 3 months! To thaw, let it sit in the fridge overnight. Be sure to reserve some of the crushed Oreos to be added later on as toppings so they don’t get soggy!

I recommend freezing it right after you mix all the ingredients together (but before chilling). This way, the oats will only soak up the milk when it is being thawed. However, you can also freeze it even after it has been left in the fridge overnight. The oats will be a bit softer but it is still delicious!

FAQs

Can I use quick-cooking or instant oats instead of old fashioned rolled oats?

No, the texture will be different. With quick-cooking/quick or instant oats, they will turn out mushy.

If you only have quick-cooking oats on hand (or if you really want/need to use them up), you can try to only let them sit in the fridge for 1-2 hours. This way, the texture will still be different but they won’t get mushy and they still remain tasty. Note that I have not tried this trick using instant oats.

Can I also add chia seeds?

Yes, you can! Note that chia seeds will absorb moisture so I advise adding 3 parts plant-based milk to 1 part chia seeds to compensate (i.e. add 3 Tablespoons plant-based milk for every 1 Tablespoon of chia seeds).

What kind of container should I use?

My favorite container to use are small mason jars but feel free to use any other small containers you have on hand. I like to reuse glass jars from peanut butter, jams, apple sauce, et cetera so I recommend saving them instead of throwing them away!

If you are making a bigger batch, you can opt to store them in a bigger container, and only portion them out before they get served.

How long are overnight oats good for?

They can be kept in the fridge for up to 5 days, or in the freezer for up to 3 months!

Notes

Ingredients Notes:
