Four-ingredient Strawberry Banana Oats Smoothie

You heard right, this creamy, thick, delicious, and healthy banana strawberry oats smoothie is made with just simple kitchen ingredients that you already have on hand. So you will need only:

Strawberries: I recommend buying fresh strawberries from the store or from the garden. But if you buy the ripest fresh strawberries and let them cool in the fridge, then use them for the best flavor in your smoothie!

Banana: Use a ripe banana to get more flavor, but you can use a frozen banana like frozen strawberries. (Did you know that bananas are a prebiotic fiber food that helps digestion and your gut health?)

Milk: Use your favorite type of milk, but I use almond milk in this smoothie recipe, or you can use regular milk. But if you need a dairy-free alternative, use plant based milk like almond milk or soy or pea milk.

Oats : Use rolled oats for a healthy version. But you can use regular oats too. It makes the smoothie thick and creamy, has rich in soluble fiber.

Ice: Makes the smoothie thicker, creamier, smoother, and colder, of course! I like to use 4 ice cubes in this smoothie. But you can use it as per your desired consistency, and add more or less ice. (optional)

Sweetener: Use any sweetener, such as honey, maple syrup, or sugar, or you can use dates for a natural sweetener. But honestly, ripe bananas are sweet enough, so simply omit the sweetener. (optional)

Vanilla Extract is totally optional, but it improves the taste.

Optional add ins: Feel free to add chia seeds and/or hemp seeds for extra nutrition of healthy fats, fiber, and omega-3s.

Want to bring a little variety in taste?

Yes, you can!

Adding Berries: Feel free to add frozen raspberries, blueberries, or mixed berries instead of the frozen strawberries. They are high in protein and high in fiber to help your gut health. This will make this smoothie more flavorful, delicious and taste like a jam of berries. I love personally, adding raspberries in this smoothie makes me feel crazy.

Want Green: Adding kale or spinach makes this smoothie green in color. Also, this is so much healthier too.

Make it dairy-free: Add your favorite plant-based milk (almond milk or coconut milk etc) and also add vegan yogurt to it.

Want to add more natural nutritional boosters?

Sure, you can! Adding these healthy ingredients makes this strawberry banana smoothie flavorful, high in protein and rich in fiber. Let’s take a look at what I suggest:

Avocado: To add healthy fats, fiber, and potassium to your smoothie, just add ripe avocado to create a thick, creamy smoothie. Usually, 1/4 or 1/2 of an avocado will be sufficient for the smoothie drink and it will also help keep you full because of these healthy fats.

Flaxseed: Usually, one tablespoon is enough for the smoothie. This is one of my best healthy ingredients that has fiber and minerals to add to a smoothie, works as a little booster. Also, it helps increase milk supply for newborn mothers.

Veggies: If you want a green smoothie, adding green veggies can make the smoothie healthier. Try adding a cup or two of raw or cooked spinach or kale or use some frozen cauliflower for another boost of veggies.

Protein: Adding protein to a smoothie makes it so much higher in protein. Adding 1/2 cup of Greek yogurt or 1 scoop of your favorite protein powder, like unflavored whey or pea protein or vanilla protein powder also be a good option.

N.B.: If you want to add more ingredients, then you will need more milk to balance the consistency. No worries! Just add a little at a time and blend until the smoothie is creamy and smooth, but make sure it remains thick.

Consistency: I like both thick creamy and thinner like consistency smoothie, depending on my mood. But you can make your own consistency by adding milk or frozen strawberries and a banana. Adding more milk makes the smoothie thinner, and adding frozen fruits makes it creamier and thicker.

Use any milk: Feel free to use any kind of milk, whatever you like. You can make this high protein strawberry banana oatmeal smoothie dairy-free and vegan by adding homemade yogurt or dairy-free coconut yogurt. But if you love dairy-free milk, use almond milk, soy milk, cashew milk, coconut milk, or any kind of store-bought dairy-free milk as well. I love to use regular milk on it because it boosts protein.

Don’t add ice: Ice cubes make the recipe cold, but they water down the taste, make it feel watery in every bite, and reduce the flavor of the smoothie.

Can you make this smoothie ahead of time?

Yes, you can. In fact, you just make this high protein strawberry banana oatmeal smoothie recipe ahead of time, typically lasting in the freezer for 2–5 days in an airtight container.

Also, you can store the strawberries and bananas in the freezer, so they last longer (up to 3–6 months for best quality).
