Ingredients

Made with wholesome, easy-to-find ingredients, this blended oats recipe brings together creamy Greek yogurt, ripe banana, and cozy cinnamon for a deliciously satisfying breakfast. The flavors are comforting and familiar- perfect for a quick weekday meal or a nourishing grab-and-go option. Whether you’re new to blended overnight oats or already love them, this blended version is a must-try!

• Rolled oats: A great source of soluble fiber (especially beta-glucan), which supports gut health, balanced blood sugar, and long-lasting fullness. You can use regular or gluten-free oats depending on your preference.

• Almond milk: A light, dairy-free option that keeps the oats smooth and creamy without added saturated fat. Choose an unsweetened version to keep the sugar content low.

• Plain Greek yogurt: Adds a creamy texture and a satisfying protein boost, plus gut-friendly probiotics that support digestion, immune health, and inflammation. You can use full-fat or low-fat depending on your needs. This is a great way to sneak in beneficial bacteria for your microbiome!

• Chia seeds: Tiny but mighty, these seeds are rich in fiber, omega-3 fats, and antioxidants. They help thicken the oats and support blood sugar balance and digestive health. Since the seeds soak overnight, they’re easier to digest!

• Ripe banana: Naturally sweetens the oats while adding potassium, vitamin B6, and prebiotic fiber to fuel good gut bacteria. The riper the banana, the sweeter your oats will taste.

• Vanilla extract: Enhances the natural sweetness and adds a warm, cozy flavor to the mix. You can also use vanilla bean paste for a more intense vanilla note.

• Cinnamon: A little cinnamon is an addition that helps regulate blood sugar and adds comforting flavor. Plus, it pairs perfectly with banana and oats!

How to Make This Perfect Make-Ahead Breakfast

Step One: Add Ingredients to a Blender

Combine the rolled oats, almond milk, Greek yogurt, chia seeds, banana, vanilla extract, and cinnamon in a high-speed blender.

Tip: Use a ripe banana for the best texture and natural sweetness. If your blender struggles with thicker mixtures, add a splash more almond milk.

Step Two: Blend Until Smooth

Blend everything on high for 30–60 seconds, or until the mixture is smooth and creamy with no visible chunks of oats or banana.

Step Three: Pour Into Containers

Divide the blended mixture evenly between two jars or airtight containers. Seal with a lid.

Step Four: Refrigerate Overnight

Place the jars in the refrigerator and let them chill for at least 4 hours, or overnight, to allow the oats and chia seeds to thicken.

Step Five: Add Toppings & Enjoy

In the morning, give the oats a good stir and top with your favorite add-ins, such as fresh berries, nut butter, or granola, for added flavor and texture.

Tips, Variations, + Substitutions

• Blend for 30-60 seconds for a pudding-like texture. You can blend for less time if you prefer a more chewy texture!
• Use any milk you like or have on hand instead of almond milk. This includes oat, soy, cow’s whole milk, or cashew milk. While they will all work great, they may alter the flavor profile slightly.
• Up the protein content even more by mixing in a scoop of vanilla protein powder or collagen powder.
• Use fairly ripe bananas for natural sweetness and better blending. Brown spots are preferred here!
• No banana? Skip the banana and use pure maple syrup or honey as a natural sweetener instead. 
• Add 1–2 tbsp cocoa powder for a chocolate version.
• No rolled oats? Use steel-cut oats, instant oats, or quick oats instead. 
• Dairy-free? Use a plant-based yogurt instead of Greek yogurt. I like this brand because it still contains protein and probiotics.

How to Store It

Store your blended overnight oats in an airtight container or mason jar in the refrigerator for up to 4 days. 

They’re perfect for meal prep. Just grab a jar, stir, and add your favorite toppings on top of the oats before eating. Now you have a delicious breakfast option for almost the entire week!  If the texture thickens too much after a day or two, simply stir in a splash of almond milk to loosen it up.
