This watermelon agua fresca (or agua de sandia in Spanish) is a bright and refreshing Mexican drink made with only 3 ingredients – watermelon, water, and a touch of sugar!
Made from a blended mixture of ripe watermelon, water, and a little bit of sugar, watermelon agua fresca (also known as agua de sandia or watermelon water) is one of the most refreshing summer drinks you’ll ever have!
It’s best served chilled and over ice and can be garnished with some mint leaves and lime wedges for a little extra brightness.
Watermelon and other flavors of agua frescas have been a part of my childhood for as long as I can remember. I used to try all the different types at my church’s summer carnival every year, and it was one of my favorite summer drinks! It’s perfect for the family, made with minimal ingredients, and is a great way to use your summer fruit.
Watermelon Agua Fresca Ingredients
This watermelon agua fresca recipe is made from 3 simple ingredients you likely have in your kitchen:
- Watermelon: A ripe seedless watermelon is preferred since we’ll be blending it up.
- Water: Simple, clean, cold water.
- Granulated sugar: To sweeten the drink just a bit. This is completely optional depending on the sweetness of the watermelon. Start with very little, then adjust the amount as you go. You could also use a different sweetener if you prefer.
How To Make Watermelon Agua Fresca
Blend: Blend the watermelon, water, and sugar until your desired texture.
Taste: Take a sip and taste, then add more sugar if needed. You can also strain it at this point if you prefer your agua fresca without any pulp.
Serve: Serve the watermelon agua fresca over ice with a lime wedge and mint!
- If you prefer your agua fresca without any pulp, you can strain the blended mixture to remove any extra solids. I personally like the pulp, but everyone has different preferences, so you do you!
- This agua fresca makes a great base for a summer cocktail. Just mix in your favorite liquor of choice and enjoy it by the pool.
- Agua de sandia can be kept in the fridge for 3 days. If you can’t finish it in time, pour any leftovers into ice cube trays and freeze it for up to 3 months!
- If you omit the sugar in this recipe, you can even make ice cubes to give to your pets!
