Last winter while staring at a bunch of forgotten celery in my fridge I had an idea. Instead of just tossing it in stock what if it became the star? That moment of kitchen curiosity led to this velvety soup that makes everyone forget they're eating celery. Now when I spot celery in the crisper my family gets excited knowing what's coming.
More Than Just Celery
This soup will change how you think about celery forever. Sweet leeks and onions transform those humble stalks into something magical. My neighbor dropped by while it was simmering and wouldn't leave without the recipe. Even my son who picks celery out of everything asks for seconds of this soup.
Ingredients for Success
- Celery: Use fresh stalks and leaves for maximum flavor.
- Leek: Adds sweetness and depth to the soup.
- Sweet Onion and Garlic: Aromatic essentials that form the flavor base.
- Butter: Real butter enhances richness.
- Flour: Thickens the soup to create a creamy texture.
- Stock: Use chicken or vegetable stock for a flavorful liquid base.
- Heavy Cream: Adds a velvety finish to the soup.
- Dried Thyme: Brings subtle herbaceous notes.
- Optional Garnishes: Celery leaves, a swirl of cream, and crusty bread for serving.
Step-by-Step Instructions
- Build the Base
- Melt butter in a large pot over medium heat. Add chopped celery, leeks, onions, and garlic. Sauté until softened but not browned, about 10 minutes.
- Add Flour and Stock
- Sprinkle in flour, stirring to coat the vegetables. Gradually add stock while whisking, ensuring no lumps form. Bring to a simmer.
- Simmer and Blend
- Simmer for 15–20 minutes until vegetables are very tender. Use an immersion blender or high-speed blender to puree the soup until smooth.
- Finish with Cream
- Stir in heavy cream and a tiny splash of lemon juice. Taste and adjust seasoning with salt and pepper as needed.

Kitchen Secrets
Through many pots of soup I've learned some tricks. Those celery leaves aren't just pretty they pack so much flavor save them for garnish. Keep the heat gentle we don't want any browning that ruins the pretty green color. A tiny splash of lemon at the end makes everything pop. My daughter loves helping stir in the cream watching it swirl into the soup.
Time to Enjoy
We love serving this soup with a little swirl of cream on top and those saved celery leaves sprinkled over. Last week I served it in teacups at my book club and everyone thought it was so fancy. My husband insists on crusty bread for dunking catching every last drop of that velvety goodness.
Save for Later
This soup keeps beautifully in the fridge just warm it gently when you're ready for more. Sometimes I freeze small portions for busy nights when we need some comfort food fast. A splash of fresh cream while reheating brings back that silky texture we love.
Mix It Up
Sometimes I toss in a potato for extra creaminess. My sister makes it dairy free with coconut milk and loves it just as much. Fresh dill makes it taste like spring while a pinch of smoked paprika adds warmth on winter nights. Each pot becomes its own little adventure.
Simple Magic
This soup reminds me that sometimes the simplest ingredients make the most memorable meals. What started as a way to use up celery turned into a family favorite that brings warmth to our table. Watching someone's face light up when they taste it makes all the chopping and stirring worth it.
