Soupe de Fenouil
This silky fennel and potato soup is delicate, creamy, and lightly perfumed with anise notes from fennel and fresh tarragon. Creme fraiche adds gentle tang and richness, while potato gives the soup a velvety body without making it heavy.

- 2 cloves (10 g)garlic cloves, sliced

Instructions
- 1
Prepare all the vegetables first so the soup cooks quickly: thinly slice the fennel and onion, slice the garlic, and dice the potatoes into small 1-2 cm pieces for even cooking. Chop the tarragon.
- 2
Heat the olive oil in a medium saucepan over medium heat. Add the fennel and onion with half the salt, and cook for 5-6 minutes, stirring often, until softened but not browned. Add the garlic for the last 30 seconds; keeping the vegetables pale gives the soup its delicate flavor and color.

Add the diced potatoes, vegetable broth, remaining salt, and black pepper. Bring to a boil, then reduce to a lively simmer and cook for 12-14 minutes, until the potatoes and fennel are completely tender and a knife slides in easily.

Take the pan off the heat and blend the soup until completely smooth using a stick blender, or carefully transfer to a blender in batches. Stir in the creme fraiche and lemon juice, then blend again briefly for a silky finish. If the soup seems too thick, loosen it with a splash of hot water.
- 5
Return the soup to low heat for 1-2 minutes just to warm through; do not boil after adding the creme fraiche or it can lose its fresh taste. Stir in most of the tarragon, reserving a little for garnish. Taste and adjust seasoning if needed.

Ladle into warm bowls, top with the remaining tarragon, and serve immediately.

Notes
- •For an extra-silky texture, pass the blended soup through a fine sieve, though this is optional for a beginner-friendly version.
- •Choose firm waxy or all-purpose potatoes; they cook quickly and give body without becoming gluey.
- •A small drizzle of olive oil or an extra spoon of creme fraiche on top makes the soup feel more bistro-style.
- •Serve with toasted bread or a simple green salad for a light meal.
