1. Prepare all vegetables by slicing fennel bulbs, peeling and dicing cucumber, and roughly chopping the onion. Reserve some pretty fennel fronds for garnish.
2. Add fennel, cucumber, onion, vegetable broth, yogurt, and lemon juice to a high-powered blender.
3. Blend on high speed for 1-2 minutes until completely smooth and creamy. The mixture might look foamy at first—this is normal.
4. Taste and season with salt and white pepper, starting conservatively since you can always add more.
5. Pour soup into a covered container and refrigerate for at least 1 hour, though 2-3 hours is even better for flavor development.
6. Before serving, stir well and taste for seasoning adjustments. Add more lemon juice if needed for brightness.
7. Serve in chilled bowls (pop them in the freezer for 10 minutes beforehand) and garnish with fresh dill and fennel fronds.
