This banana watermelon smoothie is wonderfully refreshing — a perfect summer option for a quick breakfast or a portable snack. It’s satisfyingly creamy thanks to Greek yogurt and a splash of milk, and you can make it in about five minutes with just five simple ingredients.

If you want a drink that’s both light and filling, this banana watermelon smoothie hits the mark. Watermelon and banana have become a favorite combination here: the watermelon brings a bright, fruity sweetness while the banana adds a creamy, mellow note. If you haven’t tried them together before, this smoothie is an excellent introduction.
This recipe is a bit more substantial than an all-fruit blend because it includes a generous ½ cup of plain Greek yogurt. The yogurt and a small amount of milk create a smooth, silky texture that feels indulgent without being heavy.
It’s also a great way to use up leftover watermelon or a banana that’s a little too ripe — chop, freeze, and blend for a delicious refresher.
Recipe ingredients

Ingredient notes
- Banana: Use a fresh, ripe (not frozen) banana for the best texture and flavor.
- Frozen watermelon: Freezing the watermelon gives the smoothie body without adding ice, which can water down the flavor. See the FAQs for simple freezing methods.
- Greek yogurt: Plain Greek yogurt works best. Use nonfat, low-fat, or full-fat depending on your preference; flavored yogurt is also an option if you want extra sweetness.
- Honey: Optional — add to taste if you prefer a sweeter smoothie.
Step by step photos
1. Start by adding the banana, Greek yogurt, milk, and honey (if using) to the blender. Secure the lid and blend until smooth.


2. Remove the lid and add the frozen watermelon chunks. Replace the lid and blend starting on low speed and gradually increasing as the fruit breaks down. A tamper tool can help incorporate thicker ingredients without adding more liquid.


3. Taste and add more honey if you like. Pour into a glass and enjoy immediately for the best texture and flavor.

Tips and tricks
- For consistent results, weigh the watermelon if possible. Measuring by volume can vary depending on how the pieces are packed.
- Cut watermelon into bite-sized pieces before freezing so they blend more easily.
- A blender tamper helps mix dense or frozen ingredients without adding more liquid.
- If you don’t have a tamper, add a small splash of milk to help the blender get started.
- This recipe yields about 16 ounces (473 ml). If you need more, blend in batches rather than doubling the recipe in one go to ensure proper blending.
Substitutions and additions
- Swap plain Greek yogurt for a flavored variety if you prefer a sweeter drink.
- If you don’t have Greek yogurt, regular yogurt works but will produce a slightly thinner texture.
- Use agave syrup instead of honey if desired.
- Add up to ¼ cup of other fruit (raspberries, blackberries, or strawberries) for a flavor twist without dramatically changing the texture.
- Replace dairy milk with coconut milk for a tropical note.
Recipe FAQs
Yes. The banana’s creamy, mild flavor pairs nicely with watermelon’s fresh, juicy sweetness. This smoothie showcases how well they complement each other.
Using frozen watermelon and fresh banana gives the best texture without diluting flavor. Fresh watermelon with frozen banana will still taste good but produce a thinner smoothie. Either approach works depending on your preference and what you have on hand.
To freeze: cut watermelon into bite-sized chunks and spread them on a tray until firm, then transfer to a zip-top bag for storage. If you’re short on freezer space, portion the amount you need into a flat zip-top bag, separate pieces as best you can, and freeze flat. This helps prevent large clumps and keeps chunks easier to blend.
