Recipe FAQs

What fruit mixes well with watermelon?

Watermelon pairs well with strawberries and bananas, like in this recipe, or with other tropical fruits like mango and pineapple.

What can I do with a lot of watermelon?

If you have a lot of fresh or frozen watermelon to use up, there are plenty of ways! Make a fruit salad, grill the watermelon on skewers, make a watermelon salsa, or freeze into watermelon icicles.

How do you know if watermelon is ripe?

An easy way to tell if a watermelon is ripe is by using the ‘thump test’. ‘Thump’ the rind of the watermelon with your hand and it will have a deep hollow sound when ripe. An unripe watermelon will have a higher pitched sound.

Look for a creamy yellow spot on the fruit. A yellow ground spot indicates that the watermelon has had enough time to ripen on the vine.

Can you make this without banana?

While you technically can make this smoothie without these ingredients, it will change the texture and flavor. You would need to add more frozen watermelon, but since watermelon is mostly water, it won’t be as creamy as with the added banana.


While you can pop leftover smoothies in the fridge, the texture will change quite a bit. I recommend freezing leftover smoothies and then letting them thaw slightly before enjoying again. Give it a stir and you should be good to go.

Helpful Tips

  • Fresh vs Frozen Watermelon – You can use fresh watermelon in place of the frozen, but only start with ½ cup of milk as the mixture will be more loose and watery. 
  • Freezing Watermelon – To freeze your own fruit. Cube or slice into desired size. Place fruit on a parchment lined sheet pan or tray in a single layer and freeze until solid, about 1-2 hours. Remove from the tray and place frozen fruit into a resealable plastic storage bag. Remove as much air as possible and store in the freezer. Use within 3 months.
  • Optional – Add Sweetener – This recipe is best when made with in season, sweet watermelon. If your melon is not very sweet, you can add some sugar or sugar substitute or some extra banana to help sweeten it up.
