This Strawberry Banana Smoothie is my go-to — quick, creamy, and packed with over 39 grams of protein and 9 grams of fiber. It’s the smoothie I make more than any other, especially when I need something fast that actually keeps me full. My daughter Madison loves it too, so it’s a regular in our rotation. Made with banana, strawberries, ground flax, and your favorite protein powder, it’s naturally sweet, kid-friendly, and easy to customize.
The best part? It comes together in just 5 minutes with a blender and a few simple ingredients — perfect for busy mornings or a quick post-workout snack. You can even prep it ahead to make your routine even easier.

Ingredients You’ll Need and Helpful Tips
Here are the ingredients for this strawberry banana smoothie. See the recipe card below for the exact measurements.
- Low-Fat Milk: Use your favorite type of milk. Fairlife is my go-to, but if you need a dairy-free alternative, I prefer those with higher protein content, such as soy or pea milk.
- Banana: Use ripe, spotty bananas for a sweeter smoothie without adding sugar.
- Strawberries also add sweetness. Fresh or frozen berries will work.
- Ground Flax provides fiber, protein, and many vitamins and minerals, like thiamine and copper.
- Protein Powder: I make this recipe with unflavored whey or pea protein, but vanilla protein powder would also be a good option.
- Vanilla Extract is optional, but it enhances the flavor.
- Ice makes the smoothie thicker, smoother, and colder. If it isn’t at your desired consistency, add more ice.
- Sweetener: I prefer monk fruit since it has zero net carbs and calories. However, any sweetener, such as honey, maple syrup, or sugar, would work. Or simply omit if your bananas are sweet enough.
