This banana watermelon smoothie is super refreshing - a perfect summer treat for a quick breakfast or snack on the go. And it's also satisfyingly creamy, thanks to Greek yogurt and a splash of milk. You can make this easy watermelon and banana smoothie with only 5 minutes and 5 basic ingredients!
If you are looking for a refreshing, yet satisfying smoothie, this banana watermelon smoothie is just what you need. And in fact, watermelon banana has become my new favorite flavor combo! The watermelon adds a fresh, sweet and fruity flavor, which complements the creamy mild flavor of the banana. If you've never tried this combo before - go for it - it's so delicious!
This watermelon and banana smoothie is also great because it's a bit more filling than a typical all-fruit smoothie, thanks to a generous ½ cup serving of Greek yogurt. The Greek yogurt, along with a splash of milk, help to provide that creamy texture that is so enticing.
So next time you find yourself with too much watermelon (and/or a banana that's getting a little too ripe!) you know what to make!
- Banana: unlike my kiwi banana smoothie and banana peach smoothie recipes that call for frozen banana, this banana watermelon smoothie uses a regular, non-frozen banana.
- Frozen watermelon: instead of using frozen banana, I found the best texture was achieved through freezing the watermelon instead. I talk more about how I prepped the watermelon in the Recipe FAQs section below.
- Greek yogurt: you will need plain Greek yogurt, and can use any type - nonfat, low fat, or full fat. (Unless you prefer to use flavored yogurt, which will also work!)
- Honey: the honey is optional, to add a little extra sweetness.
Step by step photos
1. The first step to making the banana watermelon smoothie is to add all the ingredients, except the frozen watermelon chunks, to the blender. Then, add the lid and blend the ingredients until smooth.
2. Then, remove the lid and add in the chunks of frozen watermelon. Replace the lid and blend until smooth. I found it's easiest to start the blender on low. Then, increase the speed as the watermelon begins to break down.
I am also using a tamper tool here, which allows you to stir the ingredients while the blender is going. This is great for thick smoothies or incorporating harder ingredients like frozen fruit and ice.
3. If you like, you can taste the smoothie and blend in a little more honey if you think it needs it. Then, just pour out the smoothie and enjoy it right away!
Tips and tricks
- Measuring the watermelon by volume can lead to differing results. This is because there will be some variance on the size of the pieces, and how tightly you are able to fit the watermelon pieces into the measuring cup. For best results, measure the watermelon by weight if you have access to a kitchen scale.
- To help the frozen watermelon blend better, make sure to cut it into bite-sized chunks, rather than large pieces, before freezing.
- Using a blender tamper tool is also a great way to help thick smoothies blend without having to add in extra liquid. This is a stick that goes through the blender lid down into the pitcher, that is used to stir the ingredients while they blend.
- If you don't have a tamper tool, you can add in a small amount of extra milk if the blender needs help to start breaking down the frozen watermelon.
- This watermelon and banana smoothie recipe will make approximately 16 ounces (473 ml). If you need more than that, work in batches, rather than adding double ingredients to the blender. That way, you will be sure to have enough room in the pitcher to blend all the ingredients properly.
Substitutions and additions
- While this watermelon and banana smoothie recipe uses plain, unsweetened Greek yogurt, if you like a little extra sweetness, you can opt for a flavored Greek yogurt instead (in addition to or instead of the honey).
- If you don't have Greek yogurt, you can substitute regular yogurt, but the texture of the smoothie will be slightly thinner.
- The honey in this smoothie is optional. If you don't have or don't like honey, but still want some extra sweetness, you can use agave syrup instead.
- Feel free to add in some extra fruit to change up the flavor; either fresh or frozen raspberries, blackberries, or strawberries would be delicious! I would keep any add-ins to only about ¼ cup, so as not to alter the texture of the smoothie too much.
- Instead of regular milk, you can try coconut milk for a more tropical flavor!
Yes! Watermelon banana is an excellent flavor combination. The creaminess and more mild flavor of the banana complements the fruity and refreshing flavor of the watermelon. If you've never tried watermelon and banana together before, this banana watermelon smoothie is a great place to start!
After testing every possible combination, I found that I could get the best texture and flavor for this watermelon and banana smoothie by using frozen watermelon and fresh banana. By freezing the watermelon, you can pack as much watermelon flavor in the smoothie as possible without risking a runny smoothie, and without having to add ice as a thickener (which also waters down the flavor!).
However, the smoothie I made using fresh watermelon and frozen banana was of course delicious, just with a thinner texture. So, if that doesn't bother you, feel free to switch it up and use fresh watermelon and frozen banana, it will still taste incredible!
Freezing watermelon for smoothies is a great way to preserve extra watermelon that may otherwise go bad. To prevent watermelon from sticking together, you can freeze it on a tray first, and then place the frozen chunks in a zip top bag. Check out this article with full instructions on freezing watermelon.
However, to be honest I am quite lazy and usually very low on freezer space, so fitting a whole tray in the freezer is a no-go for me. If you are the same, you can do my lazy method:
(1) Pre-measure the amount of watermelon chunks you need for each smoothie (for accuracy do this by weight if possible!) and add them to a quart zip top bag; (2) Spread the chunks out flat in the bag and separate them as best you can; then (3) lay the bag down flat in the freezer. I had a couple of the chunks stick together this way, but overall this method worked great for me!

Banana Watermelon Smoothie
This is a quick and easy smoothie using frozen watermelon chunks and fresh banana, plus Greek yogurt and milk for creaminess. This is a great recipe for when you have too much watermelon on your hands!

- 1 ½ cups (220 g) frozen watermelon chunks
- 1 medium ripe banana (not frozen)
- ½ cup (115 g) plain Greek yogurt - see note 1
- ¼ cup (59 ml) milk
- 1 - 2 tablespoons (20 - 40 g) honey, or to taste (optional)
- Add the banana, Greek yogurt, milk, and honey (if using) to the pitcher of a blender. Place the lid on the blender and blend until smooth.
- If the frozen watermelon chunks have stuck together, break them apart as best you can, then add them to the blender with the other ingredients. Replace the lid and blend just until smooth, starting on low speed and increasing the speed as the ingredients begin to combine. If needed, you can add in an additional small splash of milk to help the ingredients start to incorporate. Or, better yet, use a tamper tool to help combine the ingredients during blending.
- Taste the smoothie and blend in additional honey, if desired. Serve the smoothie immediately.
You can use any type of Greek yogurt you prefer, either nonfat, low fat, or full fat. If you like a little extra sweetness, you can opt for a flavored Greek yogurt instead of plain. If you don't have Greek yogurt, you can substitute regular yogurt, but the texture of the smoothie will be slightly thinner.
