Why buy a pre-made protein smoothie or shake when you can make one that’s ten times as tasty right at home? Especially when it takes less than 5 minutes and only four simple ingredients to make!

Store-bought smoothies can be pricey. Depending on the brand, they may also include fillers and preservatives.

But when you whip up your own protein shake, you save money AND you know exactly what’s going in it.

For this recipe, I use fresh or frozen strawberries, depending on what’s available. Fresh strawberries have a stronger flavor, but frozen ones give the smoothie a thicker (almost slush-ice) consistency. Both versions taste amazing!

Adding the little bit of banana just makes the smoothie more creamy, without making it taste too much of banana. We still want the strawberries to be the star of the show.

Bananas are also loaded with vitamins and minerals. They’re perfect for a post-workout shake!

I like to include flax seeds to add some healthy fat. You can leave them out if you prefer.

How to make a strawberry banana protein smoothie

Making this recipe is as simple as putting all of the ingredients in a blender and blending! So easy, right? Here are all the details:

Step 1: Put all the ingredients in a blender and blend until fully mixed (I use my Nutribullet).

Step 2: Add water until the smoothie has the desired consistency. Start out with just a little water and then slowly add as much as you like.

Step 3: Serve over ice or use frozen berries to give the smoothie a thicker (almost slush-ice) consistency.

Three simple steps, and you have yourself a perfect shake for a healthy snack or post-workout fuel up!

Getting the right consistency

The trick to making the perfect smoothie is getting the amount of liquid just right. Instead of adding all the water at once, I recommend adding it gradually until you reach the desired consistency.

The reason is that the amount of water in your strawberries and banana can vary. Frozen strawberries will also be different from fresh.

I don’t think anyone wants a watery smoothie. So my best advice is to add the water slowly.

Storage

This smoothie is best served fresh. However, if you have any leftover strawberry banana protein shake, you can store it in an airtight container in the fridge for about a day or so.

I recommend storing in as small a container as you can to minimize the amount of air in the container. This helps to prevent oxidation.

The perfect tasty snack

This protein smoothie is one of my favorite ways to refuel after a good workout. It’s super easy to make, delicious, and has 25 grams of protein for a perfect workout shake.

It’s also a great breakfast shake to start your day, or a wonderful mid-afternoon snack to cool you down on a hot day.

There’s never a bad time to enjoy a healthy, delicious smoothie!

This recipe is for one smoothie.
Since the amount of liquid in fruit can vary, you’ll want to add water gradually until you reach your desired consistency. No one wants an overly-watery smoothie!
