Start the day (or snack time!) with a simple Green Smoothie that’s designed to taste good and be easy to make—so it’s not too thick, includes accessible ingredients, and is sweet enough to help kids enjoy every sip.


Simple Green Smoothie

We make a lot of smoothies in our house since they are such an easy way to serve up a powerful dose of nutrients in an easy to drink format. I love how easy they are to vary based on what we have on hand and that they are an easy way to serve veggies to kids.

In my opinion, the key to a good green smoothie for kids is balancing the flavors and texture—so in addition to greens, you need some fruit for sweetness and creaminess.

We like to use banana since it adds a nice creamy texture and it usually makes the smoothie sweet enough that you don’t need to add any other additional sweetener. And really, you don’t need to add 27 hard to find ingredients to make a healthy smoothie for kids!

You can also use mango instead of banana if needed.

Ingredients You Need

To make this smoothie for kids, you’ll need the following ingredients, which are super easy to keep on hand in the pantry, fridge, and freezer.

  • Milk: You can use any type of milk you prefer in this smoothie recipe, though my preference is to use plant milk, such as flax or a mixed nut milk with added protein.
  • Banana: You’ll want to slice and freeze your banana ahead of time so it’s ready to go. Frozen banana makes the smoothie super creamy and delicious.
  • Frozen pineapple, strawberries, or mango: Add one other fruit—any of these work well—to the mixture for extra flavor and nutrients.
  • Spinach: You can use fresh or frozen spinach (or kale) in this recipe to add the greens. It works about the same with both of them, though freezing fresh greens can help cut down on the “green” flavor so I try to do that when I can.

Step-by-Step Instructions

Here’s a look at the simple process involved in making this simple smoothie. Scroll down to the bottom of this post for the full information.

  1. Gather your ingredients and place them all into a blender.
  2. Start the blender on low, then gradually turn the speed up and blend on high for about 30 seconds or until it’s completely blended and you see no chunks of green.
  3. Serve!

TIP: Add 1 tablespoon hemp seeds or nut or seed butter for extra healthy fats and protein.

What’s the best way to serve a smoothie to kids?

Try it using a straw cup, a little open cup, or a reusable pouch. Depending on the age and mood of your child, they may find one more suitable than others…which is to say they may play less with one or another. For my kids, we like the reusable pouch or a half full open cup with a straw best.

This green smoothie doesn’t have any added sweeteners, so it’s also a great one to give to babies if you use unsweetened nondairy milk.

What kind of milk is best in smoothies for kids?

Green smoothies are easy to make dairy-free and actually, I find that nondairy milks blend up better than dairy milk, which can separate if it sits for any amount of time after blending. Look for a milk without added sweeteners—it will say “unsweetened” on the label— and let the fruit do the work to minimize added sugars.

I like the newer plant based milks, like the Nut Protein Milk from Silk or Good Karma’s Flax Milk with Protein, which have protein amounts more similar to dairy milk.


How to Store

When made with nut butter and some hemp seeds, which helps hold the ingredients together for a longer period of time, I’ve stored this smoothie in the fridge in an airtight container for 6 hours. My toddler then drank it and was happy. I wouldn’t advice storing it any longer than that and when possible, serve it after storing.

Should you have leftovers, you can aways freeze them into a freezer pop mold and serve as a smoothie popsicle on another day.

Best Tips for Success

  • Use any milk you like, though I find that plant-milks lend the best consistency to smoothies.
  • Use spinach or kale and consider freezing the fresh leaves to cut down on the “green” flavor.
  • Add 1 tablespoon hemp seeds, 1 tablespoon nut or seed butter, or ¼ cup Greek yogurt for extra healthy fats and protein.
  • Blend really, really well.
  • Serve in a small open cup, a straw cup, or a reusable pouch.
  • Find all of my favorite Smoothie Cups to help serve this up easily.

Simple Green Smoothie

Frozen bananas give the smoothie a creamy, naturally sweet base, though you can make this with a fresh banana as long as the other fruit is frozen. It’s easy to add whatever berries or fruit you have on hand, so customize it for your kiddo.

How many stars would you give this recipe?


  1. 5 stars
    I introduced my 2 year-old and 5 year-old to smoothies with this recipe. Both the boys and my husband loved it. My 5 year-old watched the spinach go in and still happily drank it all.
    P.S. This has been my go-to site for at least the past year for various recipes, especially muffins. Thank you!

  2. I’m interested in making smoothies to send to daycare for breakfast. Any ideas on how to pack a smoothie to go?

  3. 5 stars
    How much does it yield? I have been making this spinach apple smoothie for my daughter, but I don’t know what is a good serving size.

  4. 5 stars
    Just made this for lunch for my boys (3-year-old and 16-month-old) who aren’t big lunch eaters. They loved it! Used frozen mango, banana, and spinach. I also added the Greek yogurt and a teaspoon of ground flax seeds. They loved it, and it was super easy for a pregnant mama to put together!

  5. 5 stars
    Very delicious. Love that it contains some greens. And so many variations! Our favourite is a mix of pineapple and mango with coconut milk for a bit of a tropical flavour.

    1. You could leave any added seeds out and make sure to blend it really well so the final texture is very smooth.

  6. 5 stars
    Equally good with frozen spinach and oranges. Made with unsweetened almond milk and added 2 tablespoon of Greek yogurt to kick up the creaminess and a couple of tsp of hemp for added protein.

    1. You can though it may not easily blend at first. Make sure the yogurt goes into the blender first and add a little milk if needed to get it going.

  7. I have a 9 month old and we’re trying to increase her iron intake (how I came across this post). Is this okay to give to her and is it possible to use breastmilk? Thanks!
