Hello lovelies,

this creamy kohlrabi and parsnip soup is one of my favourite starters for a festive menu. Mild kohlrabi and slightly sweet parsnips, together with potatoes, make a wonderfully velvety, blended soup – and a hint of orange brings it all to life.

The finishing touch is the topping of crispy roasted purple potatoes with rosemary and orange zest. It gives the creamy soup a lovely contrast and makes it a real eye-catcher too. A crisp element on a smooth soup is a trick I use all winter, and it is the same logic behind my vegetarian kohlrabi schnitzel with a sesame crust, where panko and sesame do the crunching. My kids especially loved exactly this topping.

This soup is part of my vegan Christmas menu and belongs to Part 2 – Carrot soup with saffron, where I share two festive soups as a starter. Parsnips carry a bowl just as well on their own, and my parsnip soup with white beans is the version I blend when I want that same sweetness ready in about 30 minutes.

TIPS

Verena's notes

Tip from my kitchen: blend the soup really smooth so it turns nice and velvety. The orange juice and zest add a fresh note – season carefully at the end so the orange only complements the mild kohlrabi and parsnip flavours. I always scatter the crispy roasted purple potatoes over the soup on the plate, so they stay lovely and crunchy.

GOOD TO KNOW

Frequently asked questions

  • Yes, the soup is perfect for making ahead. You can cook it a day in advance, chill it and gently reheat it before serving. The roasted purple potatoes are best prepared fresh so they stay crispy.

  • No, the kohlrabi leaves are optional. If you have nice fresh leaves they add a fine, slightly cabbage-like note to the soup. Without them the soup works just as well and turns out a little milder.

  • Yes, the blended soup freezes well in portions. Simply thaw it overnight and warm it gently. Add the topping fresh so it stays crispy.

  • If you cannot find purple potatoes, regular waxy potatoes work fine too. Alternatively, crispy croutons or roasted pumpkin seeds make a wonderful topping for the creamy soup.
