The temperatures jumped up quickly here in Richmond, so I’ve been reaching for smoothies on the regular. While I usually go for a banana and peanut butter combination, the warmer temperatures had me craving something lighter and hydrating. This watermelon mojito smoothie hits the spot!

The frozen watermelon chunks are a perfect base for this smoothie. The frozen strawberries add sweetness and the coconut water has electrolytes to keep you hydrated on hot days. The lime adds a bit of tang and the mint takes the cooling sensation to the next level.

Watermelon is also full of lycopene and vitamin C which are anti-inflammatory antioxidants. Thanks to its high water content, it’s actually pretty low in calories. That means it’s nutrient-dense and it tastes amazing, which is a win win!

How to Freeze Watermelon

  • Cut watermelon into 1-inch chunks and remove seeds, if needed.
  • Store it in an airtight container or freezer bag.
  • For even faster smoothies, store one cup of strawberries and one cup of watermelon chunks in small freezer bags so you can make single servings of this smoothie when you’re in a rush!

Tips & Substitution Ideas

  • When picking out frozen strawberries, be sure to check the ingredients list. Some frozen brands add sugar, but strawberries are plenty sweet on their own! Make sure you get strawberries with no added sweetener.
  • This smoothie was so refreshing on a hot afternoon and it also makes a great cocktail base! Add 4oz of rum and divide into two glasses to make tasty cocktails!
  • If you don’t have coconut water, you can use water or almond milk instead. You may want to reduce the amoount of liquid, so you don’t water down the flavor of the drink. I recommend starting with 1/2 cup and add more if necessary to blend.

If you’re looking for other fun ways to hydrate, try making a mocktail or a glass of orangeade!
