A refreshing, ultra-light bowl that tastes like summer in a spoon—minus the guilt.
Last August, when the humidity in Charleston had me practically swimming to the mailbox, I craved something cool and restorative that wouldn’t sabotage swimsuit season. I opened the fridge, spotted a forgotten English cucumber and the last fronds of a dill plant I’d sworn I’d keep alive (spoiler: I didn’t), and this soup was born. One creamy, dreamy spoonful later, my husband—devoted grilled-cheese evangelist—announced, “I could eat this every single day.” We’ve since served it at baby showers, book clubs, and even as a palate-cleanser between barbecue courses. It’s elegant enough for crystal stemware yet low-cal enough that you can return for seconds without mentally recalibrating your calorie tracker. If you need a make-ahead appetizer that looks effortless, tastes luxurious, and keeps everyone’s macros happy, bookmark this one.

Ingredients You'll Need
Great cucumber soup lives or dies by produce quality. Seek firm, unwaxed English cucumbers—those shrink-wrapped beauties have thinner skins and fewer seeds, so you skip peeling and excess water. If you can only find regular cucumbers, peel and halve them lengthwise, then drag a teaspoon down the center to scrape out seeds; your soup will still rock, just drain the chopped pieces in a sieve for ten minutes.
Fresh dill is non-negotiable. Dried dill tastes like dusty lawn clippings here. Look for fronds that are perky, not limp, and store them upright in a jar with an inch of water like a bouquet, loosely covered with the produce bag. It’ll last a week instead of three days.
For the creamy component, I use 0 % Greek yogurt. Full-fat is luscious but triples calories. If you’re dairy-free, substitute an unsweetened coconut yogurt with a squeeze of lemon to balance sweetness. Oat milk keeps the flavor neutral; almond milk can read bitter in chilled soups.
White balsamic vinegar is my secret—it’s milder than regular balsamic, so you get brightness without brown streaks. Champagne vinegar or rice vinegar work too. Avoid plain white distilled; it’s harsh.
Finally, a pinch of sugar amplifies cucumber’s natural sweetness and rounds acidity. Omit if you’re strictly no-sugar; the soup will still refresh, just taste a touch sharper.
How to Make Low Calorie Creamy Cucumber And Dill Soup
Prep the Cucumbers
Rinse and trim ends. Dice into ½-inch cubes—small enough to purée quickly yet large enough to measure accurately. You need 4 packed cups (about 550 g). Toss into a bowl with ½ tsp kosher salt, stir, and let stand 15 min. The salt draws out excess water, concentrating flavor and preventing a watery soup.
Chill Your Blender
Rinse the carafe with ice water, then pour it out. A cold blender helps the soup stay vivid green and prevents yogurt separation.
Blend Base Ingredients
Add half the cucumbers, 1 cup Greek yogurt, ¾ cup oat milk, 2 Tbsp chopped dill, 1 Tbsp white balsamic, ½ garlic clove, 1 tsp sugar, and ¼ tsp white pepper. Start on low, then ramp to high for 60 seconds until satin-smooth.
Add Remaining Cucumber
Toss in the rest of the cucumbers and pulse 4–5 times. This keeps tiny flecks for texture; think gazpacho vibes.
Strain (Optional but Velvet-Smooth)
For restaurant silkiness, pass through a fine-mesh sieve, pressing with the back of a ladle. Taste and adjust salt or vinegar.
Chill Thoroughly
Transfer to a glass pitcher, press plastic wrap directly onto surface to prevent oxidation, and refrigerate at least 2 hours. Overnight is flavor prime time.
Serve with Flair
Pour into chilled bowls, garnish with a dill sprig, a drizzle of yogurt thinned with milk, and paper-thin cucumber slices fanned like poker cards.
Expert Tips
Speed-Chill Hack
Divide soup among metal cocktail shakers and nestle in an ice bucket; drops to 40 °F in 20 min flat.
Prevent Separation
Blend in ⅛ tsp xanthan gum; your yogurt will stay emulsified for 5 days.
Dinner-Party Upgrade
Float a teaspoon of chilled vodka on each portion—turns soup into a sophisticated shooter.
Pack It for Work
Fill a thermos, top with frozen grape halves—they act as edible ice cubes and infuse subtle sweetness.
Keep It Green
Add a handful of baby spinach before blending; chlorophyll locks in color without altering flavor.
Texture Control
Reserve ¼ cup diced cucumber, toss with lime zest, and sprinkle on top for pops of crunch.
Variations to Try
- Avocado-Cucumber: Swap half the yogurt for 1 ripe avocado; adds healthy fat and extra silk.
- Spicy Korean: Blend in 1 tsp gochujang and finish with toasted sesame seeds and julienned perilla leaves.
- Protein Boost: Stir 1 cup cooked quinoa into finished soup; bumps protein to 12 g per serving.
- Mint-Pea Remix: Replace half the cucumber with frozen peas and dill with mint; serve with a swipe of ricotta on the bowl rim.
- Seafood Starter: Top each bowl with 3 chilled poached shrimp and a whisper of Old Bay.
Storage Tips
Store soup in the coldest part of the fridge, 32–35 °F, in glass jars filled to the neck. It keeps 4 days optimally, though flavor peaks at 48 hours. Stir before serving; minor whey separation is normal. For longer storage, freeze in 1-cup Souper-Cubes or silicone muffin trays. Once solid, pop out and vacuum-seal; keeps 3 months. Thaw overnight in the fridge, then re-blitz with a squeeze of lemon to wake up flavors.
If you plan to serve at a patio party, nest the serving bowl inside a larger bowl of crushed ice and stir occasionally; stays safely below 40 °F for 3 hours.
