Healthy oatmeal smoothie
This breakfast smoothie with oats is such a great way to start your morning. It’s naturally sweetened with banana, has no added sugar and contains plenty of nutrients. First, oatmeal is packed with fiber, particularly beta-glucan, which helps lower cholesterol, supports your digestion, and provides energy without spiking your blood sugar. This recipe also uses banana, which is high in vitamins and minerals, peanut butter and nondairy milk. Plus, it’s easily customizable to your diet, whether you’re looking for a high-protein, dairy-free, vegan, or gluten-free alternative.
Ingredients
Here’s what you’ll need for the perfect oatmeal smoothie, along with some substitution options and details. You can find the precise measurements in the recipe card at the bottom.
- Rolled oats. The key ingredient, they thicken the smoothie and add fiber. Use gluten-free oats if necessary, or replace with quick oats. Avoid steel-cut oats, they won’t blend.
- Banana. It adds natural sweetness and creaminess; as it blends better I recommend a frozen banana. You can swap it for other frozen fruits such as blueberries, strawberries or mango, but your oatmeal shake won’t get as creamy.
- Milk of choice. I used unsweetened almond milk to keep calories low, but any type of milk works, including cow milk or plant-based options like soy or oat milk.
- Peanut butter. Creamy peanut butter without sugar or oil is recommended, it gives a rich flavor and a creamier texture. If you desire, replace with almond butter, cashew butter, or sunflower seed butter for nut-free options.
- Cinnamon & vanilla extract. Optional but recommended, they will add a delicious flavor that perfectly matches with oats, banana and peanut butter.
- Pinch of salt. This is key to balance the flavors and enhance sweetness.
How to make oatmeal smoothie
Step 1 – Combine all ingredients. Add frozen banana, rolled oats, peanut butter, milk and a pinch of salt to a high speed blender. For more flavor, add vanilla extract and ground cinnamon. Toss in a couple of ice cubes, if the banana you are using is not frozen.
Step 1 – Blend. Blend on high speed until smooth and creamy, there should be no chunks of banana or ice left. Pour into a glass and enjoy, simple or topped with a sprinkle of oats and cinnamon.
Recipe variations
- High-protein. Add 1 scoop (30 grams) of vanilla or chocolate protein powder and blend with more milk if your protein oatmeal smoothie gets too thick. You’ll get the perfect post-workout breakfast or snack.
- Low-calorie. Use unsweetened almond milk, skip the peanut butter or swap it for PB2. If making this oatmeal smoothie for weight loss, I suggest adding a scoop of protein powder to stay full for longer.
- Dairy-free & vegan. Make sure you use plant based milk alternatives such as almond or soy milk; all other ingredients are already dairy-free.
- Gluten-free. Although they are a gluten-free food, most oats usually contain some gluten. Be sure you check on the package that yours are certified gluten-free.
- Mix-ins. Add 1 tablespoon of cocoa powder and a few dark chocolate chips for a chocolate flavor. Or add other ingredients such as blueberries, coffee powder, crumbled oatmeal cookies and 1/2 an apple for an apple banana smoothie with oats.
Success tips
- Use frozen banana for a thicker smoothie. A frozen banana enhances creaminess and has a sweeter flavor. Additionally, it also makes the smoothie more refreshing, perfect for hot days or as a post-workout.
- Add sweetness to your likings. If your banana is ripe enough, you may not need additional sweeteners at all. But for a sweeter oatmeal shake you can add some maple syrup, honey or pitted dates.
- Adjust texture as you go. If you prefer a thinner smoothie, add more milk or a splash of water. For a creamier and more filling meal, use more oats or try blending in Greek yogurt.
- Customize with your favorite mix-ins. Experiment with different flavors by adding flaxseeds, chia seeds, hemp hearts, cocoa powder, or even a handful of spinach. To make it higher in protein, add a scoop of protein powder (vanilla is bomb!).
Storage directions
This quick oatmeal smoothie recipe can be prepared right in the morning, or you can make it ahead of time if meal prepping. To store, refrigerate the smoothie – or any leftover – in an airtight jar for 1 to 2 days maximum. Shake well with a splash of milk before drinking. To maintain freshness, you can also add a squeeze of lemon juice right before storing.
For longer storage, you can freeze it for up to 2 months in a freezer-safe container or pour it into an ice cube tray. When ready to enjoy, thaw it in the fridge overnight or blend the frozen cubes with a splash of milk to bring back its creamy texture.
Frequently asked questions
Absolutely! Raw oats are completely safe to eat without needing to be soaked or cooked before making the smoothie. But if you prefer a smoother texture, I suggest soaking them in water for about 10 minutes in advance.
Yes, you can make smoothie with quick oats. As they get blended, there is no big difference in texture compared to rolled oats. However, since quick oats are more processed, they absorb liquid faster and can make your drink slightly thicker. If the consistency is too thick, simply add a bit more milk.
You can swap it for other fruits such as frozen blueberries, strawberries, mango, or a diced apple. But keep in mind that your smoothie won’t get as creamy as the one with banana.
