# Ingredient list:

→ Vegetables

01 - 1 large celery root (about 1.5 lb), peeled and diced
02 - 1 medium Yukon Gold potato, peeled and diced
03 - 1 medium leek, white and light green parts only, sliced
04 - 1 small yellow onion, chopped
05 - 2 garlic cloves, minced

→ Liquids

06 - 4 cups vegetable broth
07 - 1 cup whole milk or unsweetened plant-based milk
08 - 1/2 cup heavy cream or non-dairy cream

→ Fats & Seasoning

09 - 2 tablespoons unsalted butter or olive oil
10 - 1 bay leaf
11 - 1/4 teaspoon ground white pepper
12 - Salt to taste

→ Garnish

13 - Chopped fresh chives or parsley
14 - Cream drizzle, optional

# Cooking steps:

01 - In a large pot, melt butter over medium heat. Add leek, onion, and garlic. Sauté until softened but not browned, approximately 5 minutes.
02 - Add diced celery root and potato to the pot. Continue sautéing for 3 minutes, stirring occasionally.
03 - Pour in vegetable broth and add bay leaf. Bring to a boil, then reduce heat and simmer covered for 25 minutes until vegetables are very tender.
04 - Remove and discard bay leaf. Using an immersion blender, purée soup until completely smooth. Alternatively, transfer in batches to a countertop blender.
05 - Stir in milk and cream. Heat gently over low heat without boiling. Season with salt and white pepper to taste.
06 - Ladle into warm bowls. Garnish with chopped chives, parsley, and a cream drizzle if desired.

# Expert advice:

01 -
  • It tastes restaurant-quality but takes less than an hour, which feels like you're getting away with something.
  • Celery root's delicate flavor means this soup feels refined without being fussy or demanding.
  • Whether you're cooking for guests or just yourself on a quiet evening, it adapts to the mood you're in.
02 -
  • Don't skip peeling the celery root generously—I learned this by serving a slightly grainy bisque once and never making that mistake again.
  • If your soup breaks or separates, you probably boiled it after adding the cream; gentle heat is everything in the final stages.
  • An immersion blender makes this foolproof, but if you use a regular blender, let the soup cool slightly and blend in small batches for safety.
03 -
  • A splash of dry white wine added right after sautéing the vegetables brings an extra layer of sophistication that people will taste but not quite be able to name.
  • If you're making this ahead, refrigerate it without the cream and add the milk and cream just before reheating—this keeps the texture perfectly silky.
  • The soup freezes well for up to three months; just skip the cream until you're reheating it for serving.
