Refreshing Banana & Watermelon Smoothie Recipe for Summer

If you want a smoothie that’s both light and filling, this banana watermelon combination is a winner. Watermelon adds a fresh, juicy sweetness that pairs beautifully with the banana’s creamy, mellow flavor. If you haven’t tried the pairing before, this smoothie is an easy and delicious place to start.

Unlike all-fruit smoothies, this recipe includes a generous ½ cup of plain Greek yogurt, which contributes to a richer texture and makes the drink more satisfying. A small amount of milk helps thin and smooth the blend without diluting the flavor.

Next time you have extra watermelon or a banana that’s getting ripe, try this smoothie—it’s an easy way to use up ingredients and enjoy a bright, fruity drink.

Ingredient notes

  • Banana: Use a fresh, non-frozen ripe banana for the best texture.
  • Frozen watermelon: Freezing the watermelon yields a thicker, colder smoothie without needing ice. See the Recipe FAQs for freezing tips.
  • Greek yogurt: Use plain Greek yogurt—nonfat, low-fat, or full-fat all work. Flavored yogurt can be used if you want extra sweetness.
  • Honey: Optional—add to taste if you prefer a sweeter smoothie.

2. Remove the lid and add the frozen watermelon chunks. Replace the lid and blend, starting on low and increasing speed as the watermelon breaks down. A blender tamper is helpful for thick blends and frozen fruit.

3. Taste and add more honey if desired. Pour and enjoy immediately.

Tips and tricks

  • Measure watermelon by weight for consistent results—volume measurements can vary depending on piece size.
  • Cut watermelon into bite-sized pieces before freezing so it blends more easily.
  • A blender tamper helps incorporate thick ingredients without adding extra liquid.
  • If you don’t have a tamper and the blender struggles, add a small splash of milk to help the blades catch.
  • This recipe yields roughly 16 ounces (473 ml). If you need more, blend in batches so the blender has room to work.

Substitutions and additions

  • Use flavored Greek yogurt for extra sweetness, or stick with plain yogurt and add honey if desired.
  • If you don’t have Greek yogurt, regular yogurt will work though the smoothie will be slightly thinner.
  • Replace honey with agave syrup if you prefer a different liquid sweetener.
  • Add about ¼ cup of other fruits—raspberries, blackberries, or strawberries—for a flavor twist without changing the texture too much.
  • Use coconut milk instead of regular milk for a tropical flavor.

Recipe FAQs

Are watermelon and banana good together?

Yes. The creamy, mild banana balances watermelon’s bright, refreshing taste. This smoothie highlights that complementary pairing and is an easy way to try the combination.

Can I use fresh watermelon for this smoothie?

Frozen watermelon yields the best texture without adding ice, producing a thicker, colder smoothie. Using fresh watermelon with frozen banana is also tasty but results in a thinner texture. Both approaches work—choose based on your texture preference.

How do I freeze watermelon for smoothies?

To avoid large clumps, spread bite-sized watermelon pieces on a tray to freeze individually, then transfer to a zip-top bag. If freezer space is limited, measure the portions needed, place them flat in a bag, separate pieces as best you can, and freeze flat. A few pieces may stick together, but the method is convenient and works well.
