Watermelon Nutrition

Watermelon is not just a thirst-quencher, it’s also rich in vitamin C and vitamin A. Both are powerful antioxidants that help keep our skin glowing and our immune system strong. Watermelon also contains a good amount of lycopene, a potent antioxidant known for its heart health benefits. Moreover, it’s a good source of hydration as it’s made up of 92% water, making it a perfect ingredient for a refreshing smoothie.

Ingredients measured out to make a Watermelon Smoothie: almond milk, lime juice, frozen watermelon, plain Greek yogurt and frozen raspberries.

Ingredients Needed

almond milk – the liquid base for this smoothie. I prefer to use unsweetened almond milk, but as it’s low in calories and doesn’t impact the flavor of the smoothie. Feel free to use water or another non-dairy milk of choice for the liquid base if desired.
frozen watermelon cubes – not only does frozen watermelon add a sweet and refreshing taste, but it also helps to thicken the smoothie. I used Pitaya Foods frozen watermelon pieces, but you can easily cube and freeze fresh watermelon. See my tips below on how to do that!
frozen raspberries – adds some tartness and an extra dose of antioxidants. If you don’t have frozen raspberries on hand feel free to use frozen strawberries instead.
greek yogurt – adds creaminess to the smoothie while also providing protein. I typically use full-fat Greek yogurt but feel free to use your favorite dairy or non-dairy yogurt of choice.
lime juice – adds a burst of tartness that complements the other flavors nicely. If you don’t have lime juice or limes on hand, feel free to use lemon juice!
maple syrup or honey – this is optional, but can be added if you’d prefer more sweetness in this smoothie. Agave syrup, liquid stevia or medjool dates are other options as well.

How to Cube and Freeze Watermelon for Smoothies

Freezing watermelon for smoothies is pretty straightforward:

Cut your watermelon into cubes. Aim for around 1-inch pieces, but don’t worry about being too precise.
Arrange these cubes in a single layer on a baking sheet lined with parchment paper.
Freeze until the pieces are solid, about 2 hours.
Once they’re frozen, you can transfer them to a freezer-safe bag like a Stasher bag or an airtight container. They’ll be good in the freezer for up to three months.
