Watermelon Agua Fresca
A refreshing Mexican-style watermelon drink made by blending fresh watermelon with water and lime. Lightly sweet, naturally pink and ready in 5 minutes.
Agua fresca means fresh water in Spanish, and it is one of the most refreshing drinks you can make. Fruit is blended with water, strained and brightened with lime, and that is it.
Watermelon is the classic choice because it is so juicy and naturally sweet. Most of the time it needs little or no sugar at all.
Serve it over plenty of ice with a sprig of mint. It is perfect for hot days, parties and alongside tacos or burritos.

Ingredient Notes
Watermelon: A ripe watermelon feels heavy for its size and has a creamy yellow spot where it rested on the ground. Seedless watermelon saves time.
Sweetener: Taste before adding any. A very sweet melon needs none.

How to Make Watermelon Agua Fresca
Blend
Blend the watermelon, water and lime juice on high for 30 to 60 seconds, until completely smooth.
Strain
Pour through a fine mesh strainer into a pitcher, pressing gently with a spoon. Skip this step if you like a thicker, pulpy drink.
Sweeten
Taste and stir in sugar or honey only if needed, until dissolved.
Serve
Pour over ice and garnish with mint and lime slices. Stir before pouring, as it separates as it sits.
Tips for the Best Results
- Chill the watermelon first for the coldest drink with less ice.
- Blend a few mint leaves with the fruit for extra freshness.
- Freeze some in an ice cube tray so ice does not water it down.
- A pinch of salt makes the watermelon taste even sweeter.
Common Mistakes to Avoid
| Mistake | How to fix it |
|---|---|
| Over-sweetening | Taste first; ripe watermelon is often sweet enough. |
| Using underripe melon | Pale, bland melon makes a watery drink. Choose a heavy, deeply colored one. |
| Letting it sit unstirred | The juice separates naturally; stir before serving. |
Substitutions
- Watermelon: Cantaloupe, strawberries, pineapple or mango.
- Water: Sparkling water, added after straining, for a fizzy version.
- Lime juice: Lemon juice.
What to Serve With It
- Copycat Chipotle chicken burrito
- Ground beef tacos
- Easy homemade guacamole
- Crispy air fryer shrimp
Storage and Reheating
Fridge: Refrigerate in a covered pitcher for up to 2 days. Stir before serving.
