There is nothing more satisfying than a delicious, hydrating drink to refresh and rejuvenate you on a hot day! Watermelon smoothies offer a cool, fruity flavor and deliver a nourishing blend of nutrients to keep you feeling your best. This two-ingredient recipe is a harmonious blend of juicy watermelon and sweet honeydew melon. Each revitalizing sip features a natural sweetness and hydration that will recharge your energy and satisfy your taste buds.
This easy watermelon smoothie recipe is a great way to use watermelon with a slightly grainy or fibrous texture, rather than the crisp and juicy texture we love for eating. Instead of throwing out watermelon with a less-than-ideal texture, freeze it and make an extra refreshing frozen watermelon smoothie! Reducing food waste while creating an irresistible summer drink is a win-win!

Ingredients
Watermelon: Choose a ripe watermelon with a firm, even texture and a deep, vibrant color. It should feel heavy for its size and have a slightly hollow sound when tapped. Select a seedless watermelon for convenience or deseed a seeded watermelon.
Melon: Opt for a honeydew melon or canteloupe that is firm but slightly soft to the touch at the stem end and has a sweet, fruity aroma. Honeydew offers a smooth, milder sweet flavor, while cantaloupe provides a rich, more robust sweetness. Alternatively, use another type of melon, such as Juan Canary or Galia melon, if desired.
How to Make a Watermelon Smoothie
- Combine ingredients. Add the cubed watermelon and melon to a high-speed blender.
- Blend. Cover and blend until smooth. Serve!
Recipe Pro-Tips
- Use a high-speed blender. A high-speed blender ensures the watermelon shake has a smooth, even consistency. If you don’t have one, blend the ingredients in small batches and consider straining the liquid if needed before serving.
- Use frozen fruit for a thicker texture. Freeze the watermelon and melon cubes before blending for a frostier, creamier texture without needing ice.
- Add a garnish. Garnish your glass with a slice of watermelon, melon, or lime for a visually appealing presentation. Or sprinkle a few pieces on the healthy watermelon smoothie for added texture and flavor.
- Serve chilled. For the best watermelon smoothie experience, serve in a chilled glass. You can also serve with frozen fruit, which act as flavorful ice cubes that enhance the flavor as they melt.
Recipe Variations
Below are optional variations you can make to this watermelon shake recipe to make it your own:
- Vanilla Vegan Yogurt: Add ½ cup of vanilla vegan yogurt for an extra creamy texture and a subtle vanilla flavor. It enhances the smoothie’s richness and adds a slight tanginess.
- Lime Juice: Add the juice of ½ fresh lime for a refreshing, tangy kick. It brightens up the fruit flavors and adds a zesty contrast.
- Orange Juice: Add ¼-½ cup of fresh orange juice for a burst of citrusy sweetness and a boost of vitamin C. Adjust the amount based on your preference for sweetness and tartness.
- Mint: A handful of fresh mint leaves (about 6-8 leaves) adds a refreshing, tangy kick to watermelon smoothie recipes. Blend it with the fruit and garnish with extra leaves for a decorative touch. Basil is delicious too!!
- Frozen Strawberries: Add ½-1 cup of frozen strawberries for a tasty strawberry watermelon smoothie. Or use frozen blueberries, raspberries, or a mix to give the smoothie a fruity tartness and extra thickness. This also helps keep the smoothie cold without needing ice.
- Greens: Incorporate 1 cup of fresh spinach or 1 tablespoon of your favorite greens powder for an added nutritional boost.
- Protein Powder: Mix in 1 scoop of your favorite plant-based vanilla or unflavored protein powder to increase the smoothie’s protein content. This makes the smoothie more filling.
- Chia Seeds: Add 1 tablespoon of chia seeds to the smoothie to increase the protein and fiber content. This also contributes to hydration and makes a more filling drink.
- Sweetener: Add agave or maple syrup to taste to enhance the smoothie’s sweetness.
