Servings: 2 small slushes


  • 2 cups seedless watermelon (frozen)
  • 1 heaping cup strawberries (fresh or frozen)
  • 2 Tbsp. fresh lime juice (about 1 juicy lime)
  • Optional: 1-2 tsp. coconut sugar or agave to sweeten, fresh mint or basil, ice cubes


  • Cube watermelon and place in freezer for at least an hour or two.*
  • When ready to make, rinse and hull the strawberries.
  • Place frozen watermelon, strawberries, and fresh lime juice in blender.
  • Blend until slushy and serve immediately.


*Freezing watermelon: I set the melon cubes on a baking sheet (or shallow non-glass bowl) to freeze. They fully freeze after about 2-3 hours and become very hard. If you freeze them in a bowl, the cubes will be stuck together (and often to the bowl!) so just let thaw for 15-20 minutes before using.
If freezing a big batch, it’s sometimes easier to freeze them in a single file on a baking sheet first, then once they fully freeze to place them in a storage container for longer-term.
If your blender isn’t very strong, only freeze the watermelon for about 60-90 minutes or let thaw a bit before blending.
Try this with lemon juice instead of lime (or a combo!)
If using fresh strawberries, you may want a few ice cubes to keep it extra “slushy”, or you could freeze your hulled strawberries with the watermelon if you’d like.
Depending on how sweet your watermelon & strawberries are, you may need some extra sweetener to taste – agave, coconut sugar, etc.
