Celeriac, also known as celery root, is not to be mistaken for the more familiar traditional celery. Celeriac is grown for its root and not the stalk. Paired with potatoes and leeks as shown here, or added to stuffing, stir-fries, roasted vegetables, salads, and mashed potatoes, it packs a lovely flavour into any recipe.
A lovely substitute for celeriac is the Jerusalem artichoke. Scrape off its peel with a spoon and coarsely chop. Measure out 6 cups (1.5 L) and cook as you would celeriac.

Make this soup in bigger batches and freeze in single-serve containers. It’s extremely satisfying for a late-night winter meal.
Per serving:
Heat 2 Tbsp (30 mL) oil in large, heavy saucepan. Add leek and celeriac; sauteu0301 just until they begin to soften. Do not brown.
Stir in potatoes, diced apple, garlic, water, stock, bay leaf, and thyme sprig and bring to a boil. Cover and reduce heat to medium-low. Gently simmer for 20 minutes or until potatoes and celeriac are soft.
While soup is simmering, fill large bowl with ice water. Place parsley in strainer and plunge into saucepan of boiling water for about 5 seconds. Drain, reserving 1/2 cup (125 mL) cooking liquid, then place strainer containing parsley into bowl of ice water until cool. Once parsley and reserved liquid have cooled, drain parsley, and coarsely chop.
Place parsley in blender along with 1/2 cup (125 mL) reserved cooking liquid, 2 Tbsp (30 mL) olive oil, lemon zest, and marjoram. Pureu0301e until smooth. Add pinch of salt and freshly ground black pepper to taste. The pureu0301e can be refrigerated and made ahead, if you wish. Simply warm before serving.
When soup ingredients are soft, remove bay leaf and thyme sprig, and discard. Pureu0301e soup using handheld immersion blender or pureu0301e in food processor until silky smooth. Add salt and pepper to taste. Strain bisque through fine-meshed sieve if you wish.
Serve bisque in warmed soup bowls. Dollop each serving with a swirl of warm Parsley Pureu0301e and a grating of fresh nutmeg.
