How to make homemade watermelon agua fresca
This is a quick overview of how to make this recipe. Scroll down for the full recipe instructions and ingredient amounts in the recipe card below
- Step 1: Place chopped watermelon in a blender
- Step 2: Add sugar and lime juice and puree until blended
- Step 3: Pour watermelon mixture into glasses and top off with sparkling water
- Step 4: Garnish your glasses with fresh mint sprigs and watermelon slices
Hint: If you are using still water you can add it to the blender with the other ingredients and puree.

Expert recipe tips
- Use ripe watermelon - A sweet, juicy watermelon will give you the best flavor. Select a watermelon that feels heavy for its size and has a yellow spot where it rested on the ground.
- Chill your ingredients - Using cold watermelon, lime, and sparkling water makes for an extra-refreshing cold drink without adding ice.
- Blend well and strain – If you prefer a smoother texture, strain the blended watermelon through a fine mesh sieve to remove excess pulp. However, that pulp is full of flavor so give it a try before straining!
- Seedless Watermelon – If your blender is powerful seeds won’t matter but a seedless watermelon will guarantee that your watermelon agua fresca has a nice texture.
- Garnishes – Garnish your watermelon juice with a sprig of mint, slice of lime or lime wedge
- Adjust the sugar – The amount of added sugar will depend on the sweetness and ripeness of your watermelon. So your watermelon is really sweet, you may want to add less sugar than the recipe calls for. If the watermelon isn’t the sweetest, you may want to add extra sugar.
- Added Watermelon Flavor and Texture - If you want a stronger watermelon flavor, add an extra cup or two of watermelon, without changing the other ingredient amounts. This will give you a stronger fruit flavor and a thicker consistency.
Substitutions
- Lime - If you don’t have lime, fresh lemon juice will add a similar bright citrus flavor.
- Mint - For a slightly different herbal note, swap mint for fresh basil.
- Sparkling water – I love the added bubbles of a sparkling water but if you prefer a milder taste, replace the sparkling water with regular filtered cold water.
- Granulated sugar – Replace granulated sugar with honey, agave syrup, or simple syrup.
Variations
- Honey Sweetened Watermelon Water - If your watermelon isn’t sweet enough, add a drizzle of honey too!
- Spicy Watermelon Water - Add a pinch of cayenne or a few slices of jalapeño for a spicy kick.
- Tajin and Watermelon - Rim the glasses with chili lime seasoning for flavor and color. Watermelon and Tajin seasoning is a delicious combination of flavors.
- Coconut Watermelon Water - Replace the sparkling water with coconut water for an extra boost of electrolytes and flavor.
- Strawberry Watermelon Water – Add a cup of fresh strawberries to your blender when pureeing the watermelon.
- Mint Watermelon Water – Add some fresh mint leaves in the blender with the watermelon and lime juice and blend them together for a fresh mint flavor.
- Raspberry Watermelon Agua Fresca – Add a cup of fresh raspberries to the blender for an extra fruity drink.
- Watermelon Cocktail - You can easily transform this non-alcoholic drink into a happy hour option with a shot of vodka or tequila.
Equipment
- Blender
- Chef Knife
- Measuring cups
- Measuring spoons

Storage
- Refrigeration - Store your watermelon water in an airtight container or pitcher in the refrigerator for up to 2 days. There may be some separation so be sure to stir it before serving.
