With just a few simple pantry staples and a short list of fresh ingredients, this fennel soup recipe is easy on the wallet. Here’s what you’ll need for this recipe (see recipe card for details):
- Olive Oil – extra virgin for sautéing the veggies.

Recipe FAQs
What Part of Fennel is Used for Soup?
For this soup recipe, we’re chopping the bulb, the white part of fennel and saving the fronds for garnish.
How to Chop Fennel For Soup:
We’re chopping the fennel bulb into small, bite size pieces. First you’ll slice the fronds off at the top of the fennel bulb, discarding the tough parts of the fronds that attach it to the bulb. Keep the fronds for garnish and smoothies! Remove the brown edged, tough, outer layers of the bulb and chop off the base of the bulb. Slice the bulb into thin pieces, and then cut those pieces crosswise – like an onion.
What Does Fennel Taste Like in Soup?
Cooking fennel softens its otherwise sharp, raw flavors. Since we’re sautéing the fennel, its flavor is transformed into sweet, buttery and complex. It’s quite nice.
Expert Tips
- Make Ahead – this is this kind of soup that’s perfect for the work week. Its flavor improves with a little time.
- Variation – I adapted this soup with fennel recipe from BonAppetit Magazine where they use Mustard Greens in lieu of Kale. When I can find Mustard Greens, I use them in this recipe. They are fabulous! But, they can be hard to find.
- Garlic and Lemon – if you love these two together, you can get away with adding more in this recipe.
