When the thermometer hits 90°F, the last thing I want to do is stand over a hot stove. This chilled cucumber avocado soup is my go-to answer for 'what to eat for dinner on a hot day.' It's cool, creamy, and comes together in a blender with zero heat.

I top it with quick garlic shrimp for protein, but you can skip the shrimp and add white beans for a vegetarian version. It's the kind of dinner that makes you feel like you're at a spa, but it's easy enough for a Tuesday night.
The soup is thick and satisfying, but light enough that you won't feel weighed down. Plus, it's loaded with hydrating cucumber and healthy fats from avocado.
Why You'll Love This Recipe
About the Ingredients
2 large English cucumbers (about 2 lbs / 900g), peeled and chopped
English cucumbers have fewer seeds and a thinner skin. If using regular cucumbers, peel and seed them to avoid bitterness.
2 ripe avocados, pitted and peeled
Use avocados that yield to gentle pressure. If they're too firm, they won't blend as creamy.
1/2 cup (120ml) plain Greek yogurt
Adds tang and creaminess. Use dairy-free yogurt for a vegan version.
2 tablespoons (30ml) fresh lemon juice
Prevents browning and brightens flavors. Lime juice works too.
1 small garlic clove, minced
For the soup. Adjust to taste.
1 teaspoon salt, plus more to taste
Use fine sea salt for even seasoning.
1/2 teaspoon ground cumin
Adds warmth without heat. Smoked paprika is a good sub.
1/4 cup (60ml) olive oil, divided
Extra virgin for flavor. Use 2 tbsp for the soup and 2 tbsp for the shrimp.
1 lb (450g) large shrimp, peeled and deveined
Use fresh or thawed frozen. If you prefer, substitute with cubed chicken or tofu.
2 cloves garlic, minced (for shrimp)
Fresh garlic is best. Garlic powder works in a pinch.
1/4 teaspoon red pepper flakes (optional)
Adds a subtle kick. Omit if you don't like heat.
Fresh dill or chives for garnish
Optional but pretty. Cilantro also works.
Tips & Tricks
- Chill the soup for at least 30 minutes before serving – it lets the flavors meld and makes it extra refreshing.
- If you're short on time, use frozen shrimp and thaw them quickly in a bowl of cold water for 10 minutes.
- Don't over-blend the soup – you want it smooth but not pasty. Pulse until just combined.
- Taste and adjust salt after blending – avocado can absorb a lot of seasoning.
Pro Tips
Step-by-Step Instructions
1. Blend the soup
In a blender, combine chopped cucumber, avocados, Greek yogurt, lemon juice, 1 minced garlic clove, salt, cumin, and 2 tablespoons olive oil. Blend until completely smooth, about 1-2 minutes. If it's too thick, add 2-3 tablespoons cold water.
2. Chill the soup
Transfer the soup to a large bowl, cover, and refrigerate for at least 30 minutes or up to 4 hours. This step is essential for a cold, refreshing soup.
3. Season the shrimp
Pat the shrimp dry with paper towels. In a bowl, toss with the remaining 2 tablespoons olive oil, 2 minced garlic cloves, red pepper flakes (if using), and a pinch of salt.
4. Cook the shrimp
Heat a large skillet over medium-high heat (about 375°F / 190°C). Add the shrimp in a single layer and cook for 2 minutes per side until they turn pink and opaque, and the internal temperature reaches 145°F (63°C). They should feel firm to the touch.
5. Assemble the bowls
Ladle the chilled soup into bowls. Arrange the warm shrimp on top. If you like, add a few ice cubes to the soup to keep it extra cold.
6. Garnish and serve
Sprinkle with fresh dill or chives, a drizzle of olive oil, and a crack of black pepper. Serve immediately.
Delicious Variations
Vegetarian
Skip the shrimp and add 1 cup of cooked white beans (like cannellini) for protein.
Spicy
Add a jalapeño (seeded) to the blender for a green kick.
Herbaceous
Add a handful of fresh basil or mint to the blender for a different flavor profile.
How to Store Chilled Cucumber Avocado Soup with Garlic Shrimp

Frequently Asked Questions
Q: Can I make this soup ahead of time?
Yes, you can make the soup up to 1 day ahead. Store it in the fridge, but add the shrimp right before serving to keep them crisp.
Q: How do I keep the soup from turning brown?
The lemon juice helps prevent browning, and storing it with a piece of plastic wrap directly on the surface will also help. It's best eaten within 2 days.
Q: Can I use frozen avocado?
Yes, thaw it first and pat dry. Frozen avocado can be a bit more watery, so you may need to adjust the consistency with a little less yogurt.

Sour cream or crème fraîche work well. For a dairy-free option, use coconut yogurt or silken tofu.
