Ingredients You’ll Need
- 5 to 6 cups seedless watermelon (cut into 1-2 inch cubes)

How to Make Fresh Watermelon Lemonade
Step 1: Blend the Base
- Add watermelon cubes, water, and granulated sugar to your blender.
- Blend until smooth. I use the smoothie setting twice to get it extra velvety.
For step 2: Strain the Juice
- Pour the mixture through a strainer into a large pitcher or bowl.
- Use a spoon to help press all the juice through, discarding the pulp.
Step 3: Add Citrus and Sweetness
- Stir in the lemon juice, lime juice, and agave nectar (if using).
- Mix until the sweeteners are fully dissolved. Taste and adjust sweetness if needed.
Step 4: Serve
- Pour over ice in glasses.
- Garnish with watermelon slices, mint, and lemon wedges for a pretty presentation.

Flavor Variations
- Strawberry Watermelon Lemonade: Add 1/2 cup strawberries before blending.
- Minty Lemonade: Blend mint leaves right into the mix for extra freshness.
- Sparkling Version: Use sparkling water instead of still for a fizzy finish.
- Frozen Watermelon Smoothie: Freeze watermelon cubes first and blend without ice.
Health Benefits of Watermelon Lemonade
- Watermelon: Rich in lycopene and hydrating electrolytes.
- Lemon & Lime: Loaded with vitamin C and detoxifying benefits.
- Natural Sweeteners: Agave or honey make it a healthier choice than store-bought sodas.
