Creamy Parsnip & Celery Root Bisque Recipe

This luxurious parsnip and celery root bisque is velvety, comforting, and naturally gluten-free. The earthy sweetness of parsnips blends beautifully with creamy celery root to create a smooth, elegant soup perfect for chilly evenings or a cozy dinner at home.

Did you know?

Historically, parsnips were used as a natural sweetener in Europe because sugar wasn’t yet common. As a result, their natural sweetness made them popular in both desserts and savory dishes. Today, we love them for their earthy, nutty flavor in soups like this bisque.

The first time I discovered celery root, I almost didn’t recognize it at the market — this knobby root hides one of the creamiest, most elegant flavors for soups. Paired with sweet parsnips, it transforms into a cozy bowl that feels magical.

Ingredients

• 2 tablespoons olive oil or unsalted butter
• 1 medium onion, chopped
• 2 cloves garlic, minced
• 1 pound parsnips, peeled and chopped
• 1 pound celery root (celeriac), peeled and chopped
• 1 medium potato, peeled and diced
• 4 cups low-sodium vegetable or chicken broth
• 1 cup unsweetened almond milk or heavy cream
• 1 teaspoon sea salt (to taste)
• ½ teaspoon white pepper (or black pepper)
  

Ingredients Deep Dive

Instructions

Now let’s bring this cozy parsnip and celery root bisque to life.

1. First, heat olive oil or butter in a large pot over medium heat and sauté the onion and garlic until fragrant.
2. Next, add the chopped parsnips, celery root, and potato. Meanwhile, stir for 2–3 minutes so the vegetables coat in the aromatic base.
3. Then, pour in the broth and bring it to a gentle boil. Afterward, reduce the heat to a simmer.
4. While the soup simmers, cook for 25–30 minutes, or until the vegetables become very tender.
5. Once they are tender, carefully blend the soup with an immersion blender until smooth and creamy.
6. Finally, stir in almond milk or cream, season with salt and pepper, and serve hot with fresh herbs.
7. Serve warm and enjoy every comforting spoonful.
