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.

Common Recipe Questions

Mint is a refreshing substitute, or try a blend of both for greater aromatic complexity.

Is straining the soup necessary?

Straining through a fine mesh sieve will create a smoother texture but is optional if you prefer rustic body.

Can this soup be frozen?

It's best enjoyed fresh, but you can freeze in portions and blend again after thawing for restored smoothness.

Try a tiny pinch of cayenne or a splash of lime juice for extra brightness and slight heat.
