This strawberry banana green smoothie is a healthy option for kids and adults. 

Strawberry and banana smoothies are a childhood classic.

While I’m sure we made them at home, I remember I’d almost always get one in the summer when we’d go to the pool. Cool and refreshing, I’m sure it was also packed with added sugars.

This homemade strawberry, banana, and spinach smoothie is the perfect way to get more nutrients into your kiddos (or, let’s be honest, yourself). 

Plus, thanks to the sweetness of the banana and bright red color from the strawberries, your kids will never guess there’s secretly spinach mixed in!

Why you’ll love this recipe

  • Made with just 5 nutritious ingredients.
  • Just the right amount of sweet.
  • Sneaky way to get your kids (or yourself) to eat more leafy greens.
  • Easy to meal-prep!

Are smoothies good for kids?

Smoothies can be a very nutritious breakfast or snack for kids. 

In fact, once your child is able to sip out of a straw or sippy cup, they’re ready to start trying smoothies. 

However, smoothies can quickly go from a healthy option to becoming more of a dessert. To keep your smoothies healthy, try to limit or avoid ingredients like:

  • High-sugar flavored yogurts.
  • Sweetened fruit juices.
  • Sorbets, frozen yogurts, and ice cream.

What makes this healthy smoothie recipe allergen-free?

This healthy strawberry banana green smoothie is also a great option if your child has food allergies as it’s free of the top 8 food allergens.

That means that this smoothie is:

  • Dairy-free
  • Soy-free
  • Wheat-free
  • Nut-free
  • Peanut-free
  • Egg-free
  • Fish-free (although, this one I think is obvious)

It’s also:

  • Gluten-free
  • Vegetarian
  • Vegan

Ingredients Used to Make this Kid-Friendly Green Smoothie Recipe

  • Frozen banana: The key to a really yummy, thick smoothie is using frozen banana slices. I recommend freezing the sliced bananas at least a day ahead of time.
  • Strawberries: Fresh or frozen strawberries will work. You can also sub in raspberries or blueberries depending on what your kid prefers. 
  • Spinach: While optional, I love using smoothies as a way to sneak in leafy greens. Keep reading for tips on how to freeze spinach for smoothies. You could also use kale, but it’ll have a more distinct flavor. 
  • Ripple Kid’s Vanilla: To make these allergen-free, I used Ripple’s Vanilla Kid’s Dairy-Free Plant-Based Milk. While it does have added sugar, it still has 40% less added sugar than flavored milks and just as much protein as regular cow’s milk. You could also use Ripple’s Original Kid’s drink instead. 
  • Ground flax seeds: I like adding a little flax seed for an extra boost of fiber, omega-3’s and essential nutrients. You could also use chia seeds or hemp hearts instead.

How to Make Strawberry Banana Green Smoothie Freezer Packs 

To make this kid-friendly smoothie even easier, I like making smoothie freezer packs. That way, all you have to do is dump the contents of the bag into the blender, pour in milk, and blend. 

Here’s how to make smoothie freezer packs:

  1. Set out one small freezer bag per smoothie that you want to prep. 
  2. In each bag, place ½ a sliced banana, ½ cup sliced strawberries, and ½-1 tablespoon ground flax seeds. Seal the bag and place in the freezer. 
  3. In a blender, add a few handfuls of spinach and a splash of water. Blend until spinach is completely broken down. Pour spinach into an ice cube tray. I like to use this herb freezing tray instead. Freeze. 
  4. When ready to make your smoothie, simply pop one spinach cube from the tray and empty contents of the zip top bag into the blender. Add 1 cup of your plant-based milk and blend away! 

Of course you can also make this strawberry banana green smoothie without the prep work. Simply place ½ a frozen banana, ½ cup of fresh or frozen strawberries, a small handful of spinach, and 1 cup of plant-based milk in your blender. 

Tips for making this recipe

  • If using fresh spinach, you may want to blend it with the milk first to fully break down the spinach before adding the fruit and flax seeds. 
  • Slicing your peeled banana before freezing will help it blend more easily. 
  • If your kid can still taste the spinach, you can pour it back into the blender with more strawberries or banana slices.
