Hello lovelies,

as soon as it gets cooler outside, a pot of soup is on our stove at least once a week. This cauliflower fennel soup is my favorite at the moment. Fennel and onion are sweated with fennel seeds and a touch of honey, then the cauliflower simmers in vegetable stock until soft, and finally everything is blended smooth with a little cream. Crispy croutons made from bread and tofu go on top.

Fennel in soup is a tradition in my kitchen, I have been making my sweet potato fennel soup with orange for years. The new soup is milder and even creamier, because the cauliflower turns wonderfully velvety when blended.

Fennel, mild and aromatic

Raw fennel tastes clearly of aniseed, but when cooked it becomes surprisingly mild and slightly sweet. The fennel seeds boost the flavor a little without making the soup taste of licorice. I pick the delicate fronds off the bulb before cutting it and keep them for garnishing.

For me the croutons are the best part of this soup. I fry bread cubes and tofu cubes together in butter until golden and season them with salt, pepper, fennel seeds and a few chili flakes. The tofu makes the topping more filling, and the kids always fish out the crispy pieces first.

If you prefer fennel as a main dish, my fennel risotto with pears is a lovely idea for fall. There the bulb meets sweet pears, and the risotto turns out just as creamy as this soup.

The soup is wonderful to make ahead. I often cook it on Sunday and reheat it during the week, and only fry the croutons fresh.

And if you want to use up even more cauliflower, try my cauliflower potato soup for soup lovers. I wish you a cozy soup night.

Yours, Verena

TIPS

Verena's notes

Tip from my kitchen: in the photos I drizzled a spoonful of cream over the soup in a swirl before serving, so simply keep 2 Tbsp back for that. Press the tofu well before cubing it, then it turns crispy faster in the pan. Toasted pumpkin seeds also taste great as a topping instead of bread. For a vegan soup I replace the honey with maple syrup, the cream with oat or soy cream and the butter with olive oil.

INSTRUCTIONS

Prepare the vegetables

  1. Peel and chop the onion. Peel the garlic and chop it finely or press it.
  2. Wash the fennel, pick off the delicate fronds and set them aside for garnishing. Remove the hard core and cut the bulb into cubes.
  3. Wash the cauliflower, remove the green leaves and the stalk and divide the head into florets.

Cook the soup

  1. Heat the olive oil in a large pot over medium heat. Sweat the onion, fennel and garlic for 5 to 7 minutes without letting them brown.
  2. Add the fennel seeds, salt, honey and pepper, stir everything and cook for another 1 to 2 minutes so the flavors can develop.
  3. Add the cauliflower florets to the pot and pour in the vegetable stock until everything is covered.
  4. Bring the soup to a boil, reduce the heat and simmer for 20 to 25 minutes until the cauliflower is soft.

Blend

  1. Take the pot off the heat and add the cream.
  2. Blend the soup with an immersion blender right in the pot or in a countertop blender until completely smooth. For a chunkier soup, blend only briefly.
  3. Reheat the soup without letting it boil again and season with salt and pepper.

Fry the croutons

  1. Cut the bread and the tofu into small cubes.
  2. Heat the butter in a pan and fry the bread and tofu cubes over medium heat, turning them now and then, until golden brown and crispy.
  3. Season with salt, pepper, fennel seeds and chili flakes if you like.

Serve

  1. Ladle the soup into bowls, scatter the croutons on top, garnish with fennel fronds and serve right away.

Frequently asked questions

  • Yes, with three small changes. Replace the honey with maple syrup, the cream with oat or soy cream and the butter for the croutons with olive oil or plant-based butter. Make sure the bread is made without milk or egg.

  • No. Raw fennel tastes clearly of aniseed, but when cooked it turns mild and slightly sweet. The fennel seeds add a gentle spice. If you don't like aniseed at all, use only half the seeds or leave them out.

  • Yes, the soup freezes well and keeps for about 3 months. It is best to freeze it without the cream and stir the cream in when you reheat it. Fry the croutons fresh, because frozen ones turn soft.

  • In a tightly closed container it keeps for about 3 days. Reheat it gently and don't let it boil hard again, so the cream doesn't split. Store the topping separately so it stays crispy.

  • Firm plain tofu works best. Press it well with a kitchen towel before cutting, then it gets crispy faster in the pan. Smoked tofu gives the croutons a smoky note, in that case I go a little easier on the salt.
