Vegetable or chicken broth

How to Make Creamy Celery, Potato & Mushroom Soup

1. Sauté the Aromatics

Heat olive oil or butter in a large pot over medium heat. Add onion or leek and cook until soft. Stir in celery and mushrooms, cooking until mushrooms release their moisture and begin to brown.

2. Build the Soup

Add garlic and cook briefly until fragrant. Stir in potatoes, bay leaf, salt, and pepper. Pour in broth and bring to a gentle simmer.

3. Simmer Until Tender

Cook until the potatoes are fork-tender and the flavors have fully developed.

4. Blend Until Smooth

Remove the bay leaf. Use an immersion blender or countertop blender to purée the soup until smooth and creamy.

5. Add Cream and Adjust Seasoning

Return soup to low heat, stir in cream, and adjust seasoning as needed. Heat gently without boiling.

Expert Tips for Perfect Texture and Flavor

Brown the mushrooms well: This deepens flavor significantly.
Do not rush blending: A smooth soup defines the final result.
Season gradually: Potatoes absorb salt, so taste and adjust.

Avoid boiling after cream: Gentle heat prevents separation.
