Blended Overnight Oats – Healthy Fitness Meals


Creamy, sweet, and super easy – these Blended Overnight Oats are a recipe you’ll love for meal prepping or grab-and-go breakfasts. This high-protein and fiber-rich breakfast is made by blending together oats, Greek yogurt, milk, nut butter, and maple syrup to achieve a silky smooth texture.

If you’ve been a fan of overnight oats, this blended version will be one of your favorite ways to make it. By blitzing everything together, the oats become ultra creamy and smooth which creates a pudding-like texture once chilled. With such a simple base recipe you can customise the flavors in so many ways so you’ll never get bored. You can even blend in flavored protein powder if you want an extra boost of protein. Alternatively, you can add a couple of tablespoons of chia seeds for a thicker texture and increased fiber content.

Before You Get Started

  • You can easily replace the milk and yogurt in this recipe with vegan or non-dairy alternatives if you have a dietary restriction.
  • This recipe is perfect for meal-prepping. You can blend it up on a Sunday in just 5 minutes and have 4 breakfasts ready to go, waiting in the fridge.
  • The texture of these oats is thinner than regular overnight oats. It’s super creamy and akin to a smoothie bowl, in my opinion. If you’d like them to be thicker, stir in 2 tbsp chia seeds.
  • You can boost the protein content of these oats (and add even more flavor) if you blend in 1 scoop of your favorite protein powder.
  • I use lidded jars for storing my blended oats in the fridge so that they don’t absorb any unwanted flavors from other ingredients in the fridge.

Common Questions

How long do overnight oats last in the fridge?

Typically, they should be fine for 3 to 5 days. If you notice that they start to look or smell unpleasant, don’t consume them.

Can I use vegan dairy alternatives in this recipe?

Yes! Plant-based milks and yogurts will work great in this recipe. I like to use unsweetened versions as the recipe already includes maple syrup for sweetness.

Why leave oats overnight?

As the oats sit in the liquid, they absorb it, thickening the mixture slightly and making it really creamy. The oats also soften, which makes the mixture smooth, not grainy.

Can I use other types of oats?

You can use quick oats here; it may result in a slightly thicker end product. Don’t use steel-cut oats as they won’t break down properly and need cooking before you consume them.

Ingredients Needed

Below are the ingredients needed to make these blended rolled oats. You’ll find the full measurements in the recipe box further down the post.

  • Old-fashioned rolled oats: If you do not have rolled oats, you can use quick oats. There are Gluten-free options too. Do not use steel-cut oats.
  • Milk: You can use any kind of milk here. If using plant-based milks, use an unflavored, unsweetened variety.
  • Plain Greek yogurt: Use full-fat if you’re looking for the creamiest texture. Otherwise, low-fat or fat-free also work well. You can use thick vegan yogurt here too, if you’re dairy-free.
  • Maple syrup or honey: I like my oats to be more on the sweet side. If using honey, I tend to opt for one with a light color and flavor so that it doesn’t dominate the other flavors.
  • Nut butter: Use whatever nut butter is your favorite. For the most neutral flavour, I find cashew butter to have the most subtle taste. If you’re allergic to nuts, you can also use sunflower seed butter or tahini here instead.
  • Vanilla extract: This is optional, but I think it adds a great flavor.
  • Toppings: I love sliced fresh fruit on there, but chocolate chips or toasted seeds/nuts are delicious for textural contrast. You can also dust on ground cinnamon, cocoa powder, or matcha powder before serving.

How to Make Blended Overnight Oats

1️⃣ Blend all ingredients together

Add the oats, milk, yogurt, maple syrup/honey, nut butter and vanilla extract to the jug of a blender. Blitz together until smooth.

✏️ If you like the oats to have a bit more texture, you can blend the mixture a bit less to retain some bite.

2️⃣ Divide between jars and chill

Pour into 4 x 10-ounce jars or cups. Place in the fridge overnight.

✏️ If you want to take the oats on the go, screw a tight-fitting lid onto the jars. In the morning all you have to do is add your toppings, re-fit the lid and take it with you.

3️⃣ Top and enjoy

Add toppings to the chilled jar of blended oats then dig in!

✏️ It’s best to add toppings (especially sliced fruits) just before you’re about to eat so they remain fresh and don’t bleed into the oats.
