This 2-ingredient watermelon smoothie is refreshing, hydrating and invigorating and fabulous for breakfast or a post-workout snack.

You might know (I’ve mentioned it before) that I spent a few years as a raw vegan – with a focus on fruit.
During those years one of my favorite breakfasts was a watermelon smoothie. In fact when I was working in a corporate office, I would usually have my breakfast at my desk when I arrived in the mornings and that breakfast was 99 times out of a 100, a super large watermelon smoothie.
It was a bit of a joke in the office – to the extent that when there was a secret santa one year, I was given a massive (and I mean MASSIVE) joke mug saying ‘LARGE’ over the front.
Yes, I went large on the smoothies. Very large!
Now while I am no longer raw vegan and don’t really recommend it either, the watermelon smoothie breakfasts were not a hardship!
In fact, watermelon is one of the most hydrating fruits and yes, my skin was pretty fabulous when I was drinking this every day!
This smoothie is just 2-ingredients, it really couldn’t be simpler, or easier to throw together.
And served super cold, it is one of the most refreshing things you could drink.
I deliberately kept this smoothie simple, the reason being that watermelon doesn’t mix well (digestively speaking) with too many other fruits, AND then there’s the fact that a watermelon smoothie tastes best when it’s more like an easily drinkable juice, rather than a super thick smoothie.
So that’s why I went with lime. Watermelon and lime flavors blend beautifully, with one flavor simply enhancing the other. There’s no clashes in flavor, or contrasts in texture and that’s just perfect for the purposes of this refreshingly delicious smoothie.
Serve It Cold
I didn’t use ice in this smoothie, rather my trick to serving up a deliciously cold watermelon smoothie is to keep the watermelon in the fridge.
I prefer this to using ice, because ice dilutes the flavor.
However, if you haven’t had time to chill your watermelon, then no worries, use some ice. The important thing is that this smoothie be served cold!
You will love this watermelon smoothie, it is:
- Ice-Cold
- Smooth
- Drinkable
- Quick and Easy
- Only 2-Ingredients
- Refreshing and Hydrating
- Absolutely Delicious!
I think the best time to have this is at breakfast! But of course it works anytime of day. It’s just so fabulous for breakfast as it rehydrates you so perfectly and charges you up for the day ahead!

Easy 2-Ingredient Watermelon Smoothie
Ingredients
- 6 and ½ cups (2.2lb/1kg) Watermelon Cubed
- 2 Small Limes Juiced
Instructions
- Keep your watermelon chilled in the fridge and when you’re ready to make this smoothie, chop the watermelon into cubes and add to the blender jug.
- Squeeze the limes and add the juice to the blender jug.
- Blend well and then strain it through a kitchen sieve to remove the rough seeds so that you’re left with a very smooth drink. If you happen to use seedless watermelon you should still strain it so that your smoothie is perfectly smooth.
- Serve immediately.

Notes
- As long as your watermelon has been chilled in the fridge, there is no need to use ice. However, if you haven’t had time to chill your watermelon first, then add some ice, this drink needs to be served nice and cold.
- This drink is best served immediately but can also be stored for 1-2 days in the fridge.
I make this recipe often. So DELISH! I add a heaping teaspoon of Maldon salt and it really really brings out the flavor of both the watermelon and lime without making it salty. If anything it makes it taste sweeter! So yummy!
Love smoothies, I drink water melon smoothies often but haven’t tried with lime yet. Can’t wait until I get some limes and try out the recipe.
nice! perfect recipe.. I love it
I added Tajin to it tasted amazing
Best Recipe I have found yet I’m new at trying to eat healthy and this is so easy
Love this recipe. thanks!
Awesome! Thanks for posting Elizabeth!
Oh my God! So simple, refreshing and delicious. I only added 1/2 pack of natural sweetener, and I’m in love! Thanks for sharing
I’m just loving it?
Yay! ?❤️
I love that it was drinkable like juice versus the thickness of a smoothie. This recipe was a perfect find because I have a lot of watermelon and limes and was not sure how to use them. I put the ingredients in my Nutribullet Rx and it pulverized my watermelon seeds. When I went to strain the seeds, none existed. My spouse and I agree that this concoction is refreshing, great-tasting, and filling.
Yay! So glad you enjoyed it! Thanks for posting! 🙂
You can try making watermelon icecubes. Puree watermelon and pour into icecube trays. Then when making the smoothie, put some of the frozen cubes in to keep it cold.
That’s a great idea, thanks Valerie! 🙂
Would lemon juice work as well?
Lemon isn’t as nice a flavor blend as lime.
I used lemon juice and it worked just fine, tasted really good.
This is so delicious
Yay! So happy to hear you enjoyed it. Thanks for sharing! 🙂
Has anyone tried it with fresh mint out of your garden?
Hi Pamela, I haven’t tried it but I think it could be really nice if you crushed the mint leaves and stirred them in.
Loving watermelon smoothies during summertime, putting a Pinch or two of ground cardamom is amazing! Adds to the flavour:)!
Sounds good! Thanks for sharing Allie! 🙂
Can I use lemon juice instead? I dont like lime.
Sure!
This is amazing
