Watermelon Gazpacho is a chilled summer soup made with sweet watermelon, ripe tomatoes, crisp cucumber, red bell pepper, lime, and a touch of jalapeno. It has a smooth, refreshing texture with a balance of fruity sweetness, bright acidity, mild savory flavor, and gentle heat.
This no-cook soup takes only a few minutes to blend, but it needs at least 2 hours of chilling for the flavors to settle. Reserving some finely diced watermelon and cucumber for garnish adds fresh crunch to each bowl.
Why This Recipe Works
- Seedless watermelon supplies enough natural liquid to create a smooth soup without added water.
- Ripe tomatoes add savory depth and acidity, keeping the gazpacho from tasting like a blended fruit drink.
- Cucumber and bell pepper provide freshness and body without making the soup heavy.
- Lime juice and sherry vinegar balance the watermelon’s sweetness with two complementary types of acidity.
- Chilling the soup for at least 2 hours softens the raw onion and garlic flavors and produces a more cohesive taste.
Equipment Needed
- High-speed blender with at least a 64-ounce (1.9 L) capacity
- Large mixing bowl
- Chef’s knife and cutting board
- Fine-mesh strainer, optional
- Airtight container with at least an 8-cup (1.9 L) capacity
Ingredients List
For the Gazpacho
- 6 cups (900 g) seedless watermelon, cut into 1-inch (2.5 cm) cubes, divided
- 1 pound (450 g) ripe tomatoes, cored and roughly chopped
- 1 medium English cucumber, about 8 ounces (225 g), peeled and divided
- 1 medium red bell pepper, about 5 ounces (140 g), seeded and roughly chopped
- 1/4 small red onion, about 1 1/2 ounces (40 g), roughly chopped
- 1/2 small jalapeno pepper, seeded and roughly chopped
- 1 small garlic clove, peeled
- 3 tablespoons (45 ml) fresh lime juice
- 1 tablespoon (15 ml) sherry vinegar
- 2 tablespoons (30 ml) extra-virgin olive oil
- 1 teaspoon fine salt
- 1/4 teaspoon ground black pepper
Optional Garnishes
- 2 tablespoons (8 g) chopped fresh mint, optional
- 1 tablespoon (15 ml) extra-virgin olive oil, optional, for drizzling
- Thinly sliced jalapeno, optional, for serving
Ingredient Notes and Substitutions
- Watermelon: Choose seedless watermelon that is deeply colored, juicy, and sweet but still firm. Overripe watermelon can make the soup foamy or watery. Yellow watermelon can be substituted in the same quantity, though the soup will have a lighter color.
- Tomatoes: Ripe tomatoes give the gazpacho savory flavor and balance the sweetness of the fruit. Roma, vine-ripened, or heirloom tomatoes all work. Pale or firm tomatoes may produce a bland soup that needs additional salt and vinegar.
- English cucumber: English cucumber has thin skin and small seeds, creating a smooth, clean flavor. Persian cucumbers can replace it in the same weight. Standard cucumbers should be peeled and seeded before blending because mature seeds may add excess water.
- Sherry vinegar: Sherry vinegar adds mellow acidity and a subtle nutty flavor. Red wine vinegar can replace it in the same quantity, but the finished soup will taste sharper. Balsamic vinegar is not recommended because its sweetness and dark color can overpower the watermelon.
- Jalapeno: Jalapeno adds mild heat and fresh pepper flavor. Remove all seeds and pale membranes for a gentler soup, or omit it entirely. Serrano pepper can be substituted, but it is usually hotter, so begin with a smaller amount.
Step-by-Step Instructions
Step 1: Reserve the garnish ingredients
Set aside 1 cup (150 g) of the watermelon. Finely dice it and place it in a covered container. Cut off approximately one-quarter of the peeled cucumber, finely dice it, and refrigerate it with the watermelon for serving.
Step 2: Prepare the vegetables
Roughly chop the remaining cucumber, tomatoes, bell pepper, red onion, jalapeno, and garlic. Keep the pieces small enough to fit comfortably beneath the blender lid.
Step 3: Load the blender
Add the remaining 5 cups (750 g) watermelon, chopped tomatoes, remaining cucumber, bell pepper, red onion, jalapeno, and garlic to a high-speed blender. If the blender is crowded, process the ingredients in two batches and combine them afterward.
Step 4: Blend the vegetables and fruit
Begin blending on low speed, then increase to high. Blend for 1 to 2 minutes, until the mixture looks smooth and no visible vegetable pieces remain.
Step 5: Add the seasonings
Add the lime juice, sherry vinegar, olive oil, salt, and black pepper. Blend on high for another 30 to 45 seconds. The gazpacho should look smooth, lightly creamy, and pourable.
Step 6: Check the consistency
If the soup appears unusually thick, blend in 1 to 2 tablespoons (15 to 30 ml) of cold water. Add water only when necessary because watermelon and tomatoes naturally release plenty of liquid.
Step 7: Strain if desired
For an extra-smooth texture, pour the soup through a fine-mesh strainer into a large bowl. Press gently with a spatula, then discard the remaining seeds and skins. Skip this step for a more rustic gazpacho.
Step 8: Taste and adjust
Taste the soup before chilling. It should taste slightly more acidic and seasoned than the desired finished result because cold temperatures soften flavor. Add a small splash of lime juice or a pinch of salt only if needed.
Step 9: Chill thoroughly
Transfer the gazpacho to an airtight container and refrigerate for at least 2 hours. The soup should be completely cold, and the raw onion and garlic flavors should taste softer after chilling.
Step 10: Stir before serving
Stir the chilled gazpacho well because slight separation is normal. Taste once more and adjust the salt, lime juice, or vinegar if necessary.
Step 11: Garnish the bowls
Ladle the soup into six chilled bowls or glasses. Top each serving with the reserved diced watermelon and cucumber.
Step 12: Finish and serve
Garnish with mint, a light drizzle of olive oil, and thinly sliced jalapeno as desired. Serve immediately while thoroughly chilled.
Storage, Freezing, and Make-Ahead Instructions
- Store Watermelon Gazpacho in an airtight container in the refrigerator for up to 3 days. Stir it thoroughly before serving because the vegetable juices and olive oil may separate during storage.
- Keep the diced watermelon, cucumber, mint, and jalapeno garnishes in separate covered containers. Add them only when serving so they retain their fresh texture.
- The gazpacho can be prepared 1 day ahead. Its flavor will become more blended as it chills, although the watermelon may release additional liquid. Stir well and adjust the seasoning before serving.
- Freezing is not recommended because thawed watermelon and cucumber develop a watery, grainy texture, and the soup may separate.
FAQ
Can I make Watermelon Gazpacho ahead of time?
Yes. Prepare the soup up to 1 day before serving and refrigerate it in an airtight container. Store the diced garnishes separately and add them just before serving.
Why does my watermelon gazpacho taste too sweet?
The watermelon may be especially ripe, or the tomatoes may lack acidity. Add more lime juice or sherry vinegar 1 teaspoon at a time, along with a small pinch of salt, until the flavors taste balanced.
Can I make this gazpacho without tomatoes?
The tomatoes can be omitted, but the soup will taste fruitier and less savory. Replace them with an additional cucumber and increase the vinegar slightly to balance the extra sweetness.
How can I make the soup less spicy?
Omit the jalapeno or use only a thin slice without seeds or membranes. The remaining ingredients will still produce a flavorful, refreshing soup.
Can I use frozen watermelon?
Fresh watermelon is recommended. Frozen watermelon can make the blended soup slushy and may release excess liquid as it thaws, producing a thinner texture.
