Why You’ll Love This Watermelon Slushie

Get ready for a tropical getaway in a glass! Nothing beats sun-ripened watermelons during their peak season. Juicy, light, and refreshing, they can provide you with your daily dose of sweetness (and fiber!) while keeping you cool in the summer heat.

This is the perfect refreshing sip while sitting by the pool, after working in the garden to harvest summer produce, or to share a dye-free and no-sugar-added treat with the neighborhood kids! Homemade slushies are so quick and easy to make because they only take three ingredients. Watch out, because both children and adults will want a glass of this wonderful fruity flavor with its brilliant red hue.  

What’s the Difference Between a Slushie and a Smoothie?

The main difference between a smoothie and a slushy drink is that a smoothie is thicker and has the consistency of a milkshake. A smoothie is a blended beverage made with yogurt or milk, fruits, and juices. A slushy, like the kind from 7-11, is ice-based and made with frozen fruit or fruit and ice. Sometimes a bit of fruit juice is also added to thin it out. Both are equally delicious! Some of our fave smoothies to make during summer are this mango orange smoothie and kale pineapple smoothie. This apple cider slushie recipe is also so tasty!

The Ingredient Notes

This refreshing frozen fruit drink is surprisingly simple to make. You will only be needing a few simple ingredients and a blender.

What Could I Add to this Watermelon Slushie?

  • Sweeteners:  Watermelon slushies can be enjoyed without added sweetener, because the fruit is naturally sweet. However, depending on how sweet your watermelon is, and to satisfy your craving for some extra sweetness, you could add maple syrup or agave.
  • Basil: If you don’t like mint (or want to switch it up!), you can replace it with basil. It has a sweet-savory taste and mellower flavor than mint.  
  • Lime: Adds a zesty flavor to the sweet watermelon! Squeeze a small bit of fresh lime juice and add it to your watermelon slushies for an added boost of vitamin C.

How to Make a Watermelon Slushie

Although the prep time for watermelon slushies is only 15 minutes, freezing the fruit takes time and should be done ahead of time.  Here are the steps:

Step 1: First, remove the rind and cut the watermelon into cubes.

Step 2: Next, freeze the cubed watermelon for at least 2 hours on a baking sheet. You may lay them out separately before freezing to make them easier to blend.

Step 3: Then, in a high-powered blender, combine the frozen fruit and mint and blend on high until it forms a slushie. If the blender locks up, the watermelon is still too frozen to blend. To help the blender crush the frozen fruit quickly, try thawing it for a minute or two or add 2 tablespoons of water if the mixture is too thick. Finally, enjoy this refreshing drink right away, before it melts.

FAQs

Can I make this Watermelon Slushie ahead of time?

The water and fruit will separate if left to rest for too long, so I recommend enjoying your watermelon slush right away after blending.it 
Tip:  A quick swirl in the blender with a handful of ice cubes can always revitalize it.

How long can we keep frozen watermelon?

Frozen watermelon cubes will last in the freezer for around 6 months if stored in freezer-safe bags or containers.
Tip:  Individual servings of frozen watermelon can be kept in the freezer. This way, you won’t have to thaw the entire batch, which could compromise the quality of the remaining fruits.  

What Other Fruit Could I Add to a Watermelon Slushie?

Watermelon goes well with a variety of fruits, like strawberries, bananas, and other tropical fruits such as mango and pineapple. Strawberry is the most complementary of these fruits, as it is subtle and not overpowering. A watermelon strawberry slushie lets the watermelon stand out more than any other fruit. We kept this recipe simple so you may be creative and imaginative with whatever fruit you have on hand.
Tip:  Adding more frozen fruit can thicken your slushie. You can add water or fruit juice to thin it out.
