There’s nothing more satisfying on a warm day than a cool, fruity smoothie. This two-ingredient watermelon smoothie blends juicy watermelon with honeydew or cantaloupe for a naturally sweet, hydrating beverage that’s quick to make and easy to customize. It’s a great way to enjoy fruit that may be slightly grainy or soft for eating fresh—simply freeze the cubes and blend for an icy, slushy texture that reduces food waste and boosts refreshment.

Ingredients

Watermelon: Choose a ripe watermelon with bright color and a firm feel. Seedless is convenient, but seeded watermelon can be deseeded. If the texture is a bit grainy for eating, it works perfectly for blending or freezing.

Melon: Use honeydew for a mild sweetness or cantaloupe for a richer flavor. Look for fruit that yields slightly at the stem end and smells fragrant. Other melons like Juan Canary or Galia also work well.

How to Make a Watermelon Smoothie

• Combine ingredients. Add cubed watermelon and cubed honeydew or cantaloupe to a high-speed blender.
• Blend. Cover and blend until smooth. Pour into glasses and serve immediately.

Recipe Pro-Tips

• Use a high-speed blender. It creates a silky, even texture. If your blender is less powerful, blend in batches and strain if you prefer a smoother drink.
• Freeze the fruit for thickness. Freezing the melon cubes gives a creamier, frostier smoothie without diluting it with ice.
• Garnish for presentation. Add a small wedge of watermelon, a sprig of mint or basil, or a lime wheel to the rim of the glass.
• Serve chilled. For best flavor and texture, serve in chilled glasses or with frozen fruit that doubles as flavored ice.

Recipe Variations

Customize this simple smoothie with any of the following additions to enhance flavor or nutrition:

• Vanilla vegan yogurt: ½ cup adds creaminess and a hint of vanilla.
• Lime juice: Juice of ½ a lime brightens the flavors.
• Orange juice: ¼–½ cup adds citrus sweetness and vitamin C.
• Fresh herbs: 6–8 mint or basil leaves blended in give a refreshing herbal note.
• Frozen berries: ½–1 cup frozen strawberries, blueberries, or raspberries make the smoothie thicker and add tartness.
• Greens: Add 1 cup spinach or a scoop of greens powder for extra nutrients.
• Protein: 1 scoop plant-based protein powder makes it more filling.
• Chia seeds: 1 tablespoon boosts fiber and helps with hydration.
• Sweetener: Add agave or maple syrup to taste if you prefer a sweeter drink.

Serving Suggestions

This refreshing smoothie works well for breakfast, as a mid-day refresher, a post-workout hydrator, or paired with light dishes for brunch. Consider serving it alongside salads, veggie sticks with hummus, or chia puddings for a balanced spread.

• Pair with a light summer salad or fresh fruit.
• Serve as part of a brunch or picnic menu.
• Enjoy after a workout for a hydrating, nutrient-rich boost.

Storage Directions

Smoothies made with fresh watermelon are best enjoyed immediately to preserve their texture and flavor. If necessary, store in an airtight container in the refrigerator for up to 24 hours; shake or stir before serving, as separation may occur.
