Watermelon gazpacho is the ultimate summer soup when you want something light crisp and bursting with fresh flavor. Sweet watermelon teams up with juicy tomatoes crisp cucumber and fragrant basil for a chilled bowl that cools you down on the hottest days. I love this recipe for outdoor lunches poolside snacks or anytime I want to impress friends with minimal effort.
The first time I served this my friends asked for seconds before they finished their first bowl. It has become a must in my house every time watermelon is in season.

Watermelon has always been my favorite ingredient in this recipe. Growing up I would eat big juicy slices with my grandmother in the shade every July. Now blending it into gazpacho reminds me of those carefree afternoons and brings that same sunny spirit to my table.
Storage Tips
Keep leftover gazpacho in a sealed jar or container in the fridge. It tastes best within two days but is safe to enjoy up to three. Stir or shake well before serving each time since natural separation may occur. If you strained your soup for smoothness it will stay silkier in the refrigerator. I often store extra garnishes separately to keep them crisp.
Ingredient Substitutions
You can swap mint for basil or use both together for a more aromatic touch. If you do not have shallot a quarter of a red onion finely chopped will work although the flavor is a bit stronger. For extra tang try sherry vinegar instead of red wine vinegar. If you prefer spice a pinch of ground cayenne is excellent stirred in before chilling. Gluten free croutons make a crunchy topping for those who miss bread.
Serving Suggestions
This soup is fantastic served in chilled bowls or even small glasses for an appetizer. Pair it with a fresh green salad grilled bread or crispy chickpeas for a meal. For a party serve as shooters with mini skewers of feta watermelon and basil on the side. I have set up big pitchers of this soup for backyard picnics and it always disappears first.

Cultural and Historical Context
Gazpacho is a classic Spanish cold soup known for its brilliant colors and mix of vegetables. The addition of watermelon is a lively twist that transforms a staple from southern Spain into a modern summer favorite. While the traditional recipe highlights tomatoes peppers and garlic, using watermelon dates back only a few decades as cooks began to explore bolder summer flavors.
