Fresh watermelon, bright strawberries and just a touch of ginger make this strawberry watermelon smoothie the perfect summer refreshment. Enjoy any time of day and bask in the flavors of summer.

Any kind of melon works well in a smoothie; they are super hydrating, and are quite large! Once you learn how to cut melon, you’ll have plenty of leftovers for the likes of a cantaloupe smoothie, the watermelon smoothie below or a honeydew smoothie.

How to make a strawberry watermelon smoothie

I usually follow the 1.5+1+1 rule: 1.5 cups fruit + 1 cup leafy greens + 1 cup liquid for any smoothie I make. Yet watermelon is over 90% water, so when using this fruit in a smoothie, I cut back on the amount of water used. This way, I’ve still got a creamy smoothie in the end, instead of a juice.

If you’re working with a non high-powered blender, be sure to blend long enough to avoid strawberry seeds in your teeth along with leafy spinach chunks. Using the 2 blend method works well to really blend up the spinach, water, and watermelon before adding the remaining ingredients.

If you want to turn this smoothie into a meal, just add in a plant-based protein powder for extra protein as well as healthy fat. You’ll stay full longer and your body will turn that smoothie into long lasting energy to fuel you until lunchtime!

Eating Seasonally

Eating fruit seasonally ensures you get the best price as well as the most nutrient dense produce. It also tastes the best when harvested in season, so that’s incentive enough for me!

Also know that if you choose to buy frozen fruit, it is picked at peak ripeness then flash frozen, retaining the most nutrients. I love using 1 frozen fruit for every smoothie, and frozen strawberries work great in this strawberry watermelon smoothie.

When to buy organic produce

If buying fresh fruits and veggies is new to you, then know that just starting is great! If you aren’t able to get organic, then no sweat. I can’t buy 100% organic produce for my family and that’s okay. Instead, I follow EWG’s guide on the top produce to buy organically.

Every year EWG puts out a ‘dirty dozen‘ list, or the list of fruits and vegetables that should be bought organically to avoid the highest amounts of pesticides. I use this list as my grocery guide and *hint* strawberries always make the list.

For this smoothie, look for organic spinach and strawberries. Your body will thank you!

How do you freeze watermelon for smoothies?

Slice a watermelon into cubes, then freeze on a parchment lined cookie sheet in 1 layer. Once frozen, toss in a freezer safe bag until ready to blend. Since watermelon is mostly water (and used as part of the liquid in this strawberry watermelon smoothie), you’ll need to add some extra water when blending.

What should you not mix in a smoothie?

The sky’s the limit when it comes to green smoothies! Okay, maybe not completely…. yet if you follow my 1.5-1-1 rule (1.5 cups fruit, 1 cup leafy greens, 1 cup liquid) rule of thumb, then you can combine a lot of great fruits and greens for smoothies.

What fruit goes well with watermelon?

Berries are my go-to combo with watermelon. Cherries, strawberries, blueberries as well as açaí and lime all work great with melon.

    I was hopeful, but this one missed the mark for me. It was more like a green juice than a smoothie. There really wasn’t an ingredient to contribute a creamy consistency. The flavor was OK overall.

    1. This smoothie can totally bring the summer vibes all year long. So glad you gave it a blend!

    This is one of my all time fav smoothies. Love it! It’s so refreshing on super hot summer days.

    Refreshing smoothie for an afternoon treat. The ginger was a little strong for my taste so will cut back a little next time.
