This easy watermelon smoothie recipe is made with 5 simple Ingredients that you likely already have on hand! If you can’t find frozen watermelon in your local grocery store’s freezer aisle, I highly recommend freezing extra so you can enjoy this little slice of heaven any time of the year. 

A few tips before we jump in!

  • Use frozen fruit if possible for a creamy texture
  • If using fresh watermelon, look for seedless watermelon and freeze beforehand
  • Double the recipe and freeze for a quick and easy grab-and-go meal prepped breakfast smoothie

How to Make a Watermelon Smoothie

What You’ll Need

  • Watermelon, cubed and frozen
  • Banana, frozen
  • Greek yogurt ( I like 2-5% for extra creaminess!)
  • ½ cup milk of choice ( I used unsweetened vanilla oat milk but any will do)
  • Juice of ½ lime

Add all ingredients into a blender and blend on high until smooth. That’s it, that’s all! Pour into a glass and enjoy immediately, or freeze it for later! 

Ingredient Substitutions & Additions

  • Milk substitutes: I used unsweetened vanilla oat milk but any milk will do, including traditional dairy milk.
  • Yogurt substitutes: For a vegan version, swap the yogurt for your favorite dairy free yogurt like coconut yogurt or almond yogurt. While this particular watermelon smoothie is made with yogurt, you can also leave it out altogether. It won’t be as thick and creamy without the yogurt, but will be equally refreshing!
  • Protein Powder: The Greek yogurt in this smoothie is a great source of protein (over 20 grams!) but if you’d like even more protein, or wish to make the recipe vegan, feel free to add your favorite protein powder (obviously a plant-based option if going the vegan route!) 
  • Fruit/Vegetable substitutes: 
    • Sub half of the banana for ½ cup of frozen strawberries for a Watermelon Strawberry Banana Smoothie.
    • Add ½ cup or ⅓ of an English Cucumber for a dose of veggies in a delicious watermelon cucumber smoothie. Banana is optional in this version.
    • Other fruit that would work well with this combo: mango, pineapple, or other melon like cantaloupe or honeydew melon.
  • Add 1-2 tbsp of seeds like hemp, chia or flax for an extra does of fiber and plant-based fats and antioxidants.

How to Meal Prep this Watermelon Banana Smoothie

Even though this is the ultimate easy watermelon smoothie recipe, I’m a huge advocate of making the most of your time and making extra to enjoy later whenever you can, — instant meal, zero clean up, more free time for you! 

Meal Prep Instructions

  1. Multiply the recipe by however many meals you’d like it to last. Ex: if you’d like to have 6 servings on hand, triple the recipe.
  2. Blend up the smoothie as you would when preparing it to drink fresh.
  3. Pour the smoothie into a silicon line muffin tin and freeze until solid. Once frozen, remove the little smoothie pucks from the silicone liners and place them in a reusable storage bag like this one.
  4. Store in the freezer for up to 3 months.

How to Make from Frozen

There are two different ways you can enjoy your meal prepped smoothie from frozen:

  1. Remove from the freezer and place in a jar with a lid to thaw overnight. Before drinking, give it a good shake to mix and ingredients that have settled and enjoy!
  1. Remove from the freezer and place in a microwave safe cup. Thaw on the defrost setting until thawed enough to mix. Mix with a fork, or shake it up in a jar with a lid and enjoy!
