Pin It The first time I encountered celery root, I was completely intimidated by its knobby, alien appearance at the farmers market. The farmer convinced me to take one home, promising that beneath that rough exterior lay something magical. He was right. Now this elegant bisque has become my go-to dinner party starter because it transforms such an humble ingredient into something restaurant-worthy.
Last winter, I served this at a small dinner gathering during a snowstorm. My friend Sarah, who claims to hate celery, went back for third helpings before finally asking what was in it. Watching peoples expressions change from curious to delighted is exactly why I love cooking with misunderstood vegetables.
Ingredients
- 2 large celery roots: These ugly beauties are the star, so pick ones that feel heavy and firm
- 1 medium leek: Only use the white and light green parts for the most delicate flavor
- 1 medium onion: Yellow onion works perfectly here for sweetness
- 1 Yukon Gold potato: This is my secret weapon for extra creaminess without adding more dairy
- 2 cloves garlic: Minced fresh adds just the right background warmth
- 4 cups vegetable stock: Use a good quality one you would happily drink on its own
- 1 cup whole milk: Any unsweetened nondairy milk works beautifully too
- 1/2 cup heavy cream: This brings that luxurious restaurant quality finish
- 2 tbsp butter + 1 tbsp olive oil: The combination prevents butter from burning while adding flavor
- 1 bay leaf: Do not skip this, it adds an essential aromatic depth
- 1/4 tsp nutmeg: Freshly grated makes all the difference here
- Salt and white pepper: White pepper keeps the bisque visually pristine
Instructions
- Build your flavor foundation:
- Melt the butter with olive oil in your large pot over medium heat, then add the leek, onion, and garlic. Let them soften slowly until fragrant and translucent, about 3 to 4 minutes.
- Add the heart of the soup:
- Toss in the diced celery root and potato, stirring everything together so the vegetables get coated in all those flavorful aromatics.
- Simmer to tenderness:
- Pour in the vegetable stock, drop in the bay leaf, and bring everything to a gentle simmer. Cover the pot and let it cook for 25 to 30 minutes until a knife slides through the vegetables effortlessly.
- Blend and finish:
- Fish out the bay leaf, add the milk and nutmeg, then puree with your immersion blender until completely smooth. Stir in the cream, reheat gently without boiling, and season with salt and white pepper to taste.
Pin It This recipe became a household staple during a particularly cold February when I was recovering from surgery and couldnt stand for long. My partner would make huge batches, and wed eat it for days with different garnishes, never once getting tired of its gentle warmth.
Making It Your Own
Sometimes I add a peeled apple along with the vegetables for subtle sweetness, especially in fall. The celery roots earthiness pairs surprisingly well with fruit, and guests always try to guess the secret ingredient.
Serving Suggestions
Warm your bowls in the oven before ladling in the soup, it makes such a difference. I love serving this with homemade croutons fried in a little butter and herbs, or simply with thick slices of crusty sourdough for dipping.
Storage And Make Ahead
This bisque actually improves overnight as the flavors have time to marry and deepen. Store it in an airtight container in the refrigerator for up to 4 days.
- Gently reheat over low heat, never let it boil or the cream might separate
- Add a splash more stock or milk when reheating if it has thickened too much
- Freeze without the cream for up to 3 months, stir in cream after thawing
Pin It Theres something deeply satisfying about serving such an elegant soup that started with such an unassuming ingredient. Hope it brings as much warmth to your table as it has to mine.
Recipe Questions & Answers
- → What does celery root bisque taste like?
Celery root offers a delicate, subtle flavor reminiscent of celery but milder and slightly nutty. When pureed into a bisque, it creates a silky, sophisticated soup with gentle sweetness and aromatic depth from leeks, onions, and garlic.

Absolutely. This bisque actually benefits from resting overnight as flavors meld together. Prepare up to 2 days in advance, refrigerate, and reheat gently before serving. Add the cream and final seasonings when reheating.

Use an immersion blender directly in the pot for convenience, or transfer batches to a high-speed blender. Blend thoroughly until completely smooth, then pass through a fine-mesh sieve for extra refinement if desired.
