This chilled cucumber avocado soup is a fresh, cooling dish designed for warm-weather meals when something light and refreshing is especially welcome.
The combination of crisp English cucumber and creamy Hass avocado creates a smooth, velvety texture without making the soup feel heavy.
Fresh lime zest and juice bring bright citrus flavor that balances the richness of the avocado and yogurt or sour cream.
Fresh herbs add another layer of flavor, with cilantro, basil, or mint offering a fragrant herbal note.
Chopped scallions contribute a gentle savory sharpness, while chicken or vegetable broth gives the blended ingredients a cohesive soup-like consistency.
Greek yogurt or sour cream can be added for extra creaminess and tang, although it remains optional.
The preparation is wonderfully straightforward: the cucumber and avocado are roughly chopped, blended with the fresh herbs and scallions, then puréed with broth, yogurt, lime zest, and lime juice until completely smooth.
A few hours of chilling allows the flavors to come together while making the soup properly cold and refreshing.
For serving, optional quartered cherry tomatoes and a drizzle of extra virgin olive oil provide a simple finishing touch and a little contrast against the silky green soup.
With its vibrant ingredients, creamy texture, citrusy freshness, and make-ahead convenience, this soup works beautifully as an appetizer, light lunch, side dish, or refreshing summer course.
Chilled Cucumber Avocado Soup
Ingredients
Equipment
Method
- Prepare the Cucumber: Cut the peeled cucumbers in half lengthwise, scoop out and discard the seeds with a spoon, then cut the cucumber into roughly 1-inch chunks.
- Prepare the Avocado: Peel and pit the avocados, then cut the flesh into roughly 1-inch chunks.
- Roughly Blend the Produce: Place the cucumber, avocado, chopped fresh herbs, and scallions in a food processor or blender and pulse until the mixture is roughly chopped.
- Add the Remaining Ingredients: Pour in the broth and add the Greek yogurt or sour cream, if using, along with the lime zest and lime juice.
- Purée Until Smooth: Continue blending until the mixture becomes smooth and creamy, with the ingredients fully incorporated.
- Season the Soup: Add kosher salt and fresh pepper to taste, using approximately 1/4–1/2 teaspoon salt and 1/4 teaspoon pepper as the source suggests.
- Chill Thoroughly: Refrigerate the blended soup for 4–6 hours so it is thoroughly chilled before serving.
- Prepare the Garnish: If using the optional garnish, quarter the cherry tomatoes and drizzle them with extra virgin olive oil.
- Garnish and Serve: Add the prepared tomatoes and olive oil to the chilled soup just before serving.
Notes
- Chill the soup for 4–6 hours as specified so it is properly cold and refreshing when served.
- Use fully ripe Hass avocados for the smoothest texture and easiest blending.
- The cucumber seeds are removed before blending to maintain the intended texture of the soup.
- Greek yogurt or sour cream is optional, so the soup can be prepared without it.
- Choose cilantro, basil, mint, or a combination of the listed fresh herbs according to your preferred flavor.
- Season the blended soup gradually with kosher salt and fresh pepper, adjusting to taste.
- Add the optional tomatoes and olive oil immediately before serving for the freshest garnish.
Chef’s Secret
For the smoothest chilled soup, pay attention to the blending sequence rather than adding everything at once.
Start by pulsing the cucumber, avocado, herbs, and scallions until they are roughly chopped.
This gives the blender or food processor an easier starting point before the liquid ingredients are added.
Once the broth, yogurt or sour cream, lime zest, and lime juice are incorporated, continue puréeing until the mixture is completely smooth.
The cucumber and avocado should form a cohesive, creamy texture rather than remain visibly chunky.
After seasoning, give the soup the full 4–6 hours of chilling time specified in the recipe so the finished dish is thoroughly cold and ready to serve.
Serving Suggestions
Serve the soup chilled as a refreshing appetizer, light lunch, or side dish. For a simple finish, top each serving with the optional quartered cherry tomatoes and a drizzle of extra virgin olive oil.
The fresh tomato adds a contrasting color and texture to the smooth green soup.
A small amount of the chopped fresh herbs used in the soup can also complement the presentation.
Serve it alongside a light salad or simple bread for a more complete meal, keeping the accompaniments fresh and uncomplicated so the cucumber, avocado, lime, and herbs remain the focus.
