There’s nothing better than biting into a juicy watermelon slice (or peach!) during the hot summer days. It is one of the most hydrating fruits, containing 92% water.

It’s also a great source of antioxidants, particularly lycopene, and vitamins A and C. If you’re feeding a baby, be sure to pair plant-based, iron-rich foods with vitamin C to greatly enhance the absorption of iron, THE most essential nutrient for that age.

And if you are looking for a fun way to enjoy this summer fruit, this refreshing watermelon smoothie is the answer! 

After you try it, go and make this peach banana smoothie, apple banana smoothie, and carrot banana smoothie too!

Ingredients

All the ingredients laid out on a white background.
  • Frozen watermelon – Be sure to freeze first.
  • Frozen banana – Adds sweetness and creaminess to the smoothie. Use a ripe banana with plenty of brown spots. Here’s how to freeze bananas.
  • Yogurt – Adds creaminess and a tangy flavor while amping up protein, fat, calcium, and probiotics. You can use plain or Greek yogurt. And if you have any frozen yogurt, this will be a great way to use it up.
  • Riced cauliflower – It’s a great way to add an extra serving of veggies to your and your child’s day! You won’t taste it. You can use store-bought for convenience or if you have a big head, you can easily make cauliflower rice.
  • Hemp seeds – for a boost of protein and health fats

How to Freeze Watermelon

The freezing process is the same as for freezing peaches and banana.

Slice into desired shape and place on a baking try lined with parchment paper to prevent the watermelon from sticking to the pan.

Freeze for several hours until solid then transfer to a freezer-safe to freeze for at least 3 months.

Now you can make this watermelon sorbet or add the frozen watermelon to smoothies, oatmeal, frozen yogurt, popsicles, or enjoy as “ice cubes” in a glass of water or milk!

Substitutions

This is a highly customizable recipe and here are some simple swaps and additions to try:

  • No yogurt? You can use any milk of choice. The smoothie won’t be as creamy though.
  • Dairy-free? you can use any non-dairy yogurt of choice.
  • You can also add other frozen fruits like mango, strawberries, pineapple, etc.
  • No hemp seeds? You can add flax seeds or chia seeds or even a tablespoon of peanut, nut, or seed butter.

Tips for Success

  • Use frozen fruit for thicker and creamier smoothie. It will also make your drink nice and cold!
  • If you prefer a thinner smoothie, add more milk until desired consistency is reached.
  • Feeling hesitant about adding cauliflower? Start with 2 tablespoons and add more to your liking!
  • Although it doesn’t need it, if you desire that extra sweetness, add more fruit or honey (not for babies under 1!).

Serving Suggestions

There are two ways to enjoy this watermelon smoothie.

Watermelon Smoothie Bowl

Thick smoothie served in a bowl with chia seeds.

Blend just enough so that all the fruits get broken down. At this point, the mixture will be pretty thick, like soft serve. Transfer to a bowl and eat right away with a spoon.

To invite even more fun and nutrition, add toppings, like ground nuts and seeds, coconut, etc. I like to add chia seeds to mimic watermelon seeds ;).

If you want the smoothie to be thicker, add 1/3-1/2 cup of rolled oats – another easy and filling breakfast idea for you!

You should also try this carrot cake smoothie bowl!

Watermelon Smoothie

Smoothie in a glass jar with cubed watermelon on the side.

Keep blending until the mixture becomes smooth and pourable. Feel free to add some milk if you desire a thinner consistency.

Serve the smoothie by itself in their favorite straw cup or as a part of a meal!
