Celeriac soup transforms this humble root vegetable into a silky, creamy bowl of comfort with a delicate earthy flavor and a hint of natural sweetness. The texture is luxurious without feeling heavy, making it just as suitable for a cozy family dinner as it is for serving guests as a starter. A handful of everyday vegetables slowly cooked together creates a surprisingly rich flavor, proving that simple ingredients can produce an elegant meal.
What is Celeriac?
Celeriac, also called celery root, is the edible root of a variety of celery. While it may look unusual with its rough brown skin, the inside is smooth and pale. Its flavor is milder than celery, with gentle nutty and earthy notes that become sweeter after cooking. Once blended into soup, it creates a naturally creamy consistency that doesn’t rely on large amounts of cream.
What You Can Do Better
- Cook the onion, leek, celery, and garlic slowly instead of rushing them. This builds a naturally sweet flavor base.
- Avoid browning the vegetables if you want the soup to keep its light, creamy color.
- Blend until completely smooth for a restaurant-style texture.
- Add the cream only during the final few minutes of cooking to keep it fresh and rich.
- Taste before serving and adjust the seasoning, as celeriac benefits from enough salt and white pepper.
- Serve with homemade croutons or crusty bread for extra texture.

How to Make Celeriac Soup
- Melt the butter in a large heavy pot over medium-low heat.
- Add the onion, leek, celery, and garlic. Cook gently for about 10 minutes until the vegetables become soft and fragrant without turning brown.
- Add the cubed celeriac and potato. Stir well and cook for another 8 to 10 minutes so the vegetables begin to soften.
- Pour in the vegetable stock or water, then add the thyme, bay leaf, white pepper, and salt.
- Bring the soup to a gentle boil, reduce the heat, and simmer for 25 to 30 minutes until the celeriac is completely tender.
- Remove the thyme stems and bay leaf.
- Stir in the heavy cream and simmer for another 2 to 3 minutes.
- Blend the soup with an immersion blender until perfectly smooth. If using a countertop blender, work in small batches and allow the soup to cool slightly first.
- Taste and adjust the seasoning if needed.
- Serve hot with chopped chives, a drizzle of olive oil, crunchy croutons, and warm crusty bread.
