Creamy Roasted Parsnip Soup with Thyme

It doesn’t get much cozier than a steaming bowl of Parship Soup. This creamy parsnip soup has a velvety texture and showcases the sweet, woody flavor of parsnips, rounded out with leeks, garlic and fresh thyme. It’s simple to prepare, adaptable for vegan or dairy-free diets, and freezes beautifully for meal prep or busy weeknights.

The first time I tried parsnips I was hooked. I had overlooked them for years, but their unique sweet-earthy flavor and silky texture won me over immediately. I often use parsnips roasted with other root vegetables or mashed as a purée, and this parsnip soup lets them shine as the main ingredient.

Parsnips pair exceptionally well with mild alliums like leeks, plus garlic and a sprig of thyme for aromatics. A small amount of cream enriches the soup, but you can swap in coconut milk to make a dairy-free, vegan version without losing the luxurious mouthfeel.

Recipe ingredients

This recipe uses a short list of straightforward ingredients. Quantities and full directions are in the recipe card below.

Ingredient notes

• Parsnips: The star of the dish. They bring a sweet, woody, slightly nutty flavor and become very smooth when cooked. You’ll need about 3 pounds.
• Leeks: Use the white and light green parts for a mild, sweet onion note. Three large leeks (about 3 cups sliced) work well. If unavailable, a yellow or white onion is an acceptable substitute.
• Celery: Adds subtle savory depth. I skipped carrots here to keep the soup from turning orange.
• Garlic and nutmeg: Four cloves of garlic complement the parsnips, and a pinch of nutmeg adds a warm, background note. If you don’t have nutmeg, curry powder or cumin can be used instead.
• Vegetable stock: The recipe calls for 7 cups. You can use 4 cups of stock plus 3 cups water if preferred. Add extra liquid (1–2 cups) to thin the soup to your desired consistency.
• Thyme and bay leaf: Fresh thyme is ideal for brightness; use about 1 sprig or 2 tablespoons chopped. Substitute 1½ teaspoons dried thyme if needed.
• Heavy cream or coconut milk: Half a cup of heavy cream adds richness, but coconut milk makes a great dairy-free swap or you can omit it for a lighter soup.

How to make parsnip soup

Making this parsnip soup is straightforward. The basic steps are to sauté the aromatics, simmer the parsnips until tender, then purée the mixture to a silky smooth consistency.

Pro tip: Prep the parsnips, leeks and celery up to a few days in advance to speed up weeknight preparation.

1. Heat 2 tablespoons olive oil in a large pot over medium heat. Add the leeks and celery and cook until softened, about 5 minutes. Add the parsnips and cook 2 minutes; stir in the garlic and nutmeg and cook another 30 seconds. If the leeks begin to brown, lower the heat.
2. Pour in 7 cups vegetable stock, add a bay leaf and a sprig of thyme, then bring to a boil. Reduce heat, simmer 15–20 minutes or until parsnips are tender.
3. Remove the bay leaf and thyme sprig. Purée the soup until smooth using an immersion blender, or transfer in batches to a blender or food processor and return to the pot. Add 1–2 cups more stock or water if you prefer a thinner consistency.
4. Stir in ½ cup heavy cream (or coconut milk for a vegan option). Season with salt and pepper to taste. Serve warm, garnished with fresh thyme if desired.
