What Are Overnight Oats?

Overnight oats are made from combining whole grain rolled oats with a liquid, like almond milk, and other tasty ingredients like greek yogurt, chia seeds, nut butter, or fruit. The oats soak overnight in the liquid, soften, and have the perfect creamy texture, similar to stovetop oatmeal.

What You Need to Make Protein Overnight Oats

Old Fashioned Oats: for this recipe we’re using gluten free old-fashioned rolled oats.

Milk: my go-to liquid for overnight oats is almond milk just because I always seem to have it on hand. Of course, you can swap it for another milk of your choice!

Protein Powder: there are so many options when it comes to protein powder which means you can choose your favorite! I love to use plain or vanilla protein powder for these oats but you can switch it up and use whatever flavor you like. 

Greek Yogurt: this helps to give the oats an extra creamy texture as well as pack in a bit more protein.

Chia Seeds: these powerhouse seeds add an extra dose of healthy fats and fiber.

Sweetener: maple syrup or honey both work well to sweeten the oats.

Vanilla Extract: for a bit of vanilla flavor in every bite.

Ways to Customize

  • Add in nut butter – adding a bit of creamy nut butter is a great way to add some extra healthy fat. Almond butter, cashew butter, and peanut butter will all work.
  • Sweeten things up – if you prefer overnight oats on the sweeter side then you can add another tablespoon of sweetener.
  • Keep your oats dairy-free – swap the greek yogurt for your favorite dairy free greek yogurt instead.
  • Add extra fruit – you can mix in fresh chopped strawberries, blueberries, or even mashed bananas into the
  • Switch up the milk – instead of almond milk you can switch things up and use coconut milk or cashew milk. Regular dairy milk would be great too!

My Favorite Healthy Additions

  • Flax Seeds you can add flax seed instead of chia seeds to these oats if you like for healthy fat and fiber.

Topping Ideas

Toppings are one of the best parts of eating overnight oats for me and there are a wide variety of delicious toppings to choose from. You can go with fresh fruit, more nut butter, nuts and seeds, and so much more.

Here are a few of my favorite topping options:

How Long Do Overnight Oats Last?

Your overnight oats should last for 3-5 days in an air-tight container in the fridge. While they will still be good to eat after a few days, know that the texture of the oats may change as they soak up more liquid.

Can You Eat Them Warm?

Yes! While overnight oats are meant to be eaten cold instead of hot, like traditional oatmeal, you can heat them up if you prefer. I recommend giving them a try cold first though to see how you like them. You can set them out on the counter for around 15 minutes before eating to take the chill off.

If you would like to heat them up, you can do so by heating them for 30 seconds at a time in the microwave until warm.
