This strawberry watermelon smoothie hides a full cup of spinach behind juicy watermelon and frozen strawberries. You probably won’t taste the greens at all, only a cool, fruity, naturally sweet drink with a little ginger warmth.
It works because watermelon leads the flavor. Its mild sweetness covers the spinach, and a two-step blend leaves no leafy bits behind. Next time someone at your table side-eyes anything green, hand them this one.
Table of Contents
Why You Should Blend It
- Watermelon flavor. Its juicy, mild sweetness sits up front, so the spinach stays in the background.
- The blend order matters. First, blend the spinach with the water and watermelon. That way, every leaf breaks down before the strawberries go in.
- Ginger adds warmth. One inch of fresh ginger gives the smoothie a bright, zippy finish.
- Low calorie. This smoothie has 81 calories, 3 grams of fiber, 2 grams of protein and 13 grams of sugar. All the sweetness comes from fruit, with no added sugar.
- It’s vegan, gluten-free and dairy-free.
Strawberry Watermelon Smoothie Ingredients
Here’s a quick breakdown of why I use certain ingredients in my recipe.
- Spinach: Baby spinach tastes milder than mature leaves, and it blends silky smooth with watermelon and water.
- Watermelon: It supplies most of the liquid and sweetness, so the smoothie needs very little added water.
- Frozen strawberries: They chill and thicken the smoothie without ice, and their berry flavor leads.
- Fresh ginger: One inch adds warmth and a zippy finish that keeps the flavor lively.
- Protein powder (optional): One serving makes this smoothie filling enough to count as a meal.

How to Make Strawberry Watermelon Smoothie
- Blend the greens first. Add the spinach, water and watermelon to your blender. Blend until no leafy chunks remain.
- Add the strawberries and ginger. Drop in the frozen strawberries and fresh ginger. Then blend again until smooth.
- Pour and enjoy. Serve it in a glass right away while it’s cold.
With a standard blender, blend a little longer so the strawberry seeds and spinach bits disappear. For the silkiest result, use one of my favorite smoothie blenders.
Substitutions and Variations
- Greens: swap the spinach for another leafy green you like. Milder greens keep the flavor fruity.
- Liquid: swap the water for coconut water if you like a light, tropical taste. The nutrition numbers use water.
- Strawberries: fresh strawberries work, too. In that case, freeze your watermelon cubes to keep the smoothie cold.
- Ginger: use a smaller piece for a milder smoothie, or skip it for a plain berry-melon flavor.
- Protein: add one serving of protein powder for a more filling breakfast.
- No greens: prefer a plain melon version? Try my Watermelon Smoothie.
Make-Ahead, Storage and Freezing
- Spinach: freeze spinach so it never wilts and stays ready to blend.
- Watermelon: cube it, freeze the pieces on a parchment-lined sheet, then store them in a freezer-safe bag. Add a splash of extra water when you blend them.
- Leftovers: this smoothie tastes best right after blending. If you have extra, store it in a sealed jar in the fridge for up to 24 hours. Stir or re-blend before drinking.

Recipe Notes
- Greens Swap: Use baby spinach for the mildest flavor, or swap in another mild leafy green you like.

- Liquid Swap: Coconut water works in place of the water for a light, tropical taste. The nutrition numbers use water.
- Storing: Best fresh, but it keeps in a sealed jar in the fridge for up to 24 hours. The watermelon separates, so shake well before drinking.

Common Questions
You probably won’t. Watermelon and strawberries lead the flavor, and ginger adds warmth. Blending the spinach with the watermelon first also removes leafy bits. If you notice a green note, use a milder green or a little less spinach.
Use frozen strawberries and keep the added water to ½ cup, since watermelon already adds liquid. You can also freeze your watermelon cubes. Then add a splash of extra water only if the blender needs it.
Cut the watermelon into cubes and freeze them in one layer on a parchment-lined baking sheet. Once frozen, move them to a freezer-safe bag. Watermelon is mostly water, so you may need a little extra water when blending.
Berries are my go-to pairing with watermelon. Strawberries, blueberries and cherries all work well. Açaí and lime also pair nicely with melon.
Yes, in parts. Freeze the spinach, watermelon and strawberries ahead, then blend when you’re ready. A blended smoothie keeps in the fridge for up to 24 hours. Stir or re-blend it before you drink.
Yes. As written, this strawberry watermelon smoothie is vegan, gluten-free and dairy-free. If you add protein powder, check its label first.

Strawberries are my favorite. My watermelon was sweet so that made it even better. Never thought of adding ginger. Nice twist. I added a strawberry vegan protein powder and splash or orange juice too it.
I enjoyed the watermelon flavor with a hint of tart from my berries and the zing from the ginger. Due to travelling, I made this early on day one, froze it for a few hours, then set it out over night to thaw. (I’ve found if left to thaw in the fridge, it takes about 24 hours for a frozen smoothie to become drinkable slush again.). Probably because of this, it was more watery than slushy, which is not my favorite. Can’t wait to try it again fresh.
I really liked this one. But to be honest I did two substitutions. I used blueberries and grapes instead of the watermelon and strawberries. I used what I already had. I always make my smoothie with protein powder as a meal replacement.
I did not love this one. I ended up dumping the last 1/4 of it. For some reason, it was very chunky; an issue I’ve never had with smoothies in the past. I think it was the ginger. In the past, I’ve used ginger powder instead of ginger root, and never had an issue with texture. If I make this again, I’ll substitute out the ginger root for powder.
This smoothie is refreshing, not too sweet, and a little spicy for sure. I love ginger and spicy smoothies, but you could probably reduce the amount of ginger if you don’t tend to add ginger to smoothies already.
This smoothie is awesome ! I didn’t have all the ingredients. So i’ve swap the spinach for kale and the watermelon for cantaloupe. Loves the great ginger and mint taste. I will definitely do it again with all the original ingredients.
I bet it tasted really good with those substitutions. I may have to make your version!
