➡️ What are the benefits of strawberry and blackberry smoothies?
Smoothies are such a healthy way to start the day! They are quick and easy, but also, you can get a few portions of fruits right from the beginning of the day. This smoothie gets a ton the health benefits from berries, bananas, rolled oats and chia seeds:
- Berries: berries are packed with antioxidants, which limit oxidative stress in your body to help you fight diseases.
- Bananas: bananas are very rich in potassium, antioxidants and vitamins! Plus, bananas are naturally very sweet and will make your smoothie sweet without any added sugar!
- Rolled oats: oats are high in fiber and rich in many essential vitamins and minerals, making your smoothies thicker and more substantial. We love this smoothie as a full meal for breakfast, it is filling enough thanks to the added oats!
- Chia seeds: these tiny seeds are a superfood and particularly rich in fiber, omega-3 healthy fatty acids and high-quality plant-based protein. Chia seeds also absorb liquid easily making your smoothie thicker.
🗒 Ingredient list (+ substitutions)

- Frozen bananas: I highly recommend using frozen bananas as opposed to fresh bananas. They make smoothies so heavenly creamy and rich, that we even use them to make vegan chocolate milkshakes without ice cream! Simply buy more when grocery shopping, let them ripen on the counter and then peel them. Place them on a parchment paper-covered baking sheet and freeze for a few hours before transferring them to a large bag or container for longer storage.
- Fresh or frozen blackberries and strawberries: use fresh when in season, or freeze them the day before for an extra chilled smoothie.
- Rolled oats: choose old-fashioned rolled oats if you can, although quick oats are fine too. Oats add lots of nutrition and make the smoothie thicker and more filling.
- Plant-based milk: I like oat milk from Oatly for making smoothies, but any kind works well, such as almond milk or soy milk. Choose unflavored and unsweetened.
- Chia or hemp seeds: add healthy fats, extra fiber and protein too and it helps thicken the smoothie. Flax seeds would work too.
- Cinnamon: for flavoring, you can also use vanilla extract, a dash of cacao powder or simply omit it.

💡 Tips
- I highly recommend using frozen fruits if possible. If you only have fresh berries, then you might want to start with less milk and add more as needed, since the smoothie will already be juicier. In any cases, you will need a frozen banana to reach a super creamy smoothie.
- Soaking the oats in the milk even for a few minutes will help create a smoothie texture that is smooth and creamy without a grainy feeling. Try not to skip that step!
- Avoid adding ice cubes whenever possible as this will dilute the flavors.
- This smoothie is naturally quite sweet, so I bet you won't need any added sweetener. If your fruits are on the sour side, especially the blackberries, then add a splash of maple syrup or a softened Medjool date.

🍴 Serving suggestion
Serve right away while still cold and frozen with a straw and top with fresh fruits and chia/hemp seeds.
If serving as a healthy dessert or mid-day snack, then garnish with coconut whipped cream.
You could also serve it as a smoothie bowl (check out this healthy strawberry banana smoothie breakfast bowl for inspiration and more details!). In that case, start with less milk to make it thicker. Pour in a bowl and top with granola, a drizzle of nut/seed butter, chia or hemp seeds and fresh fruits. Dig in with a spoon!
❓ FAQs
Smoothies are best when enjoyed right away. If you do have more than you can drink, then keep covered in the fridge for up to 24 hours. To serve, blend again quickly with a few ice cubes just to refresh it.
You can measure the frozen fruits, rolled oats and seeds ahead of time and store individual portions in your freezer in a small container. That way, you only have to throw the ingredients in the blender and add the milk.
You can boost the protein content by adding a scoop of plant-based protein powder, a tablespoon of peanut or almond butter or simply more seeds.
In my case, this makes for one larger portion, as it is often the only thing I eat in the morning. But it can also make for 2 smaller portions, especially if serving for kids or with toasts.
