One great thing about summer is fresh watermelon, right? Although it doesn’t matter how many times my kids tell me they WANT a watermelon, we always have some left. Instead of throwing it out, I’ve started cubing it up and freezing it for a variety of simple drinks and smoothies. Lasts a long time in the freezer, and comes in handy for cocktails, mocktails, smoothies, and other recipes!

So this Watermelon Smoothie really is more of a smoothie rather than a mocktail or cocktail, although you could serve it as those as well. If Watermelon isn’t your thing, you might like this Mango Pineapple Smoothie! And check out this long list of other tasty smoothie recipes.
How to Freeze Watermelon
If you’ve never frozen watermelon, don’t worry, I’ve got you covered. Buy a seedless watermelon for best results. Cut it up into small to medium cubes. Try to cut into similar sized cubes. Place the watermelon cubes in a single layer on a silicone mat lined baking sheet (you could try using wax paper but the watermelon may stick). Place the baking sheet in the freezer for a few hours, then put the frozen watermelon cubes into a resealable plastic bag getting out as much air as possible.
Watermelon Smoothie Ingredients
- Frozen (seedless) watermelon cubes
- Coconut milk (or your favorite substitute such as milk)
- Plain unsweetened Greek yogurt (or sweetened if you prefer)
- Lime juice
How to Make a Watermelon Smoothie
- Place all the ingredients in a strong blender and process until smooth.
- Add more or less sweetener depending on personal taste.
- Add more liquid as needed to get blender to process or scrape down sides inside of blender (turn off blender before doing this…) if needed.
- Pour into glass and serve immediately!

Quick Tips for Best Results
- Make sure all your ingredients are as cold as possible.
- Use frozen watermelon rather than fresh. If you must use fresh watermelon, you may want to add a little ice to your smoothie to thicken it and get it nice and frozen. And get a seedless watermelon if you can.
- Use a strong blender that can easily process the frozen watermelon and other ingredients.
- Thicker yogurts will help make this smoothie thick and rich.
- Add a little honey (or sweetener of choice) at a time until the desired sweetness. Personal choice how sweet you want it or skip the sweetener all together for a healthier option.
- Be sure to process the smoothie in the blender until smooth. Depending on your blender, you may need to remove the blender pitcher or cup from the base, shake it or stir, then place back on the base and continue processing until smooth. You can add a little more liquid (such as the coconut milk) as needed for the blender to finish processing the smoothie.
Watermelon Smoothie FAQ
How should I store this Watermelon Smoothie?
I suggest drinking this smoothie right away. If you have to store it ahead of time, I’d suggest pouring the finished smoothie into an ice cube tray and freeze. Then you can pull out the smoothie cubes and place in a cup to defrost when you want.
Substitutions for the lime juice?
You can try using your favorite citrus juice such as lemon juice or orange juice.
Can I use low-fat yogurt?
You can use any type or flavor of yogurt you’d like. Although, I would suggest you pick out one that you like the taste of otherwise you may not like the smoothie. Thicker, creamier yogurts such as Greek yogurts will result in a thicker smoothie so you may need to adjust your ingredients if you use a different type.
What else can I add to this smoothie recipe?
You can definitely try adding some of your other favorite fruit such as banana, mango, strawberries, pineapple, and/or blueberries. Or try turning it into a green smoothie with a little spinach, kale, and/or cucumber. You can also try adding your favorite spices or herbs such as fresh mint leaves.
What can I use instead of honey?
You can try using your favorite sweetener of choice, or omit altogether for a healthy (or healthier…) option.
Can I use fresh watermelon instead of frozen?
I haven’t tried it, but you could. The consistency of the smoothie will be runnier and less frozen though. You may want to add a little ice to help the consistency.
