Creamy parsnip and fennel soup is January in a bowl — sweet parsnips, anise-scented fennel, leeks softened in olive oil, all blitzed silky with your choice of milk. The reserved fennel fronds on top are not an afterthought; they're the freshest note in the pot. Fifty minutes, eight bowls.
When the winter chill sets in, there’s nothing quite like a bowl of warm, comforting soup. This Creamy Parsnip and Fennel Soup is my absolute go-to. The natural sweetness of parsnips and the subtle, anise-like flavor of fennel are perfectly balanced by the savory depth of leeks and garlic. It’s an elegant, velvety soup that feels incredibly luxurious, yet it’s surprisingly simple to make. It’s guaranteed to be a star at your next holiday gathering or a welcome treat on a quiet, cozy night in.
Ingredients
• 1 Tbsp / 15 ml extra virgin olive oil
• 2 leeks, white and light green parts only, rinsed, halved, and thinly sliced
• 1 large fennel bulb, chopped, fronds reserved for garnish
• 2 medium parsnips, peeled and chopped
• 2 cloves garlic, chopped
• ¾ tsp / 3.75 ml (0.1 fl oz) sea salt
• ¼ tsp / 1.25 ml (0 fl oz) white pepper
• ¼ tsp / 1.25 ml (0 fl oz) herbes de Provence
• ¼ tsp / 1.25 ml (0 fl oz) ground fennel seed
• 2 cups / 480 ml low-sodium vegetable broth
• 1 cup / 240 ml milk of choice (dairy or unsweetened plant-based)
• ¼ cup / 60 ml (2 fl oz) plain yogurt (dairy or plant-based)
• ½ Tbsp / 7.5 ml (0.3 fl oz) fresh lemon juice
Instructions
1. Heat olive oil in a large, heavy-bottomed soup pot over medium heat. Add the sliced leeks and chopped fennel. Sauté for about 8 minutes, until softened and just beginning to brown.
2. Stir in the chopped parsnips, garlic, sea salt, white pepper, herbes de Provence, and ground fennel seed. Cook for one minute until fragrant.
3. Pour in the vegetable broth and 1½ cups / 360 ml (12.2 fl oz) of water. Increase the heat to bring the mixture to a boil.
4. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 25 to 30 minutes, or until all the vegetables are very tender.
5. Remove the pot from the heat. Stir in the milk and yogurt.
6. Carefully blend the soup until completely smooth and creamy, either with an immersion blender directly in the pot or by transferring it in batches to a standard blender.
7. Return the soup to the pot if necessary. Stir in the fresh lemon juice to brighten the flavors.
8. Ladle the soup into bowls, garnish with the reserved fennel fronds, and serve immediately.
