Parsley soup is a vibrant, velvety soup made from fresh parsley, onion, garlic, and stock, finished with a touch of cream. It’s a surprisingly elegant dish that transforms a humble herb into a rich, comforting bowl with a clean, peppery flavor. This recipe works because it balances the parsley’s brightness with buttery leeks and potato for body, creating a soup that’s both light and satisfying.
Ingredients
- 2 tbsp (30 g) unsalted butter
- 1 medium yellow onion, chopped (about 1 cup / 150 g)
- 1 leek, white and light green parts only, sliced (about 1 cup / 100 g)
- 2 garlic cloves, minced
- 1 medium potato, peeled and diced (about 1 cup / 150 g)
- 4 cups (960 ml) vegetable or chicken stock
- 4 cups (80 g) fresh flat-leaf parsley leaves and tender stems, loosely packed (about 2 large bunches)
- 1/2 cup (120 ml) heavy cream
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper, plus more for serving
- Optional garnish: extra cream, chopped parsley, or a drizzle of olive oil
Instructions
- Melt the butter in a large pot or Dutch oven over medium heat. Add the onion, leek, and a pinch of salt. Cook, stirring occasionally, until softened and translucent, about 5–7 minutes.
- Add the garlic and cook for 1 minute until fragrant.
- Stir in the potato and stock. Bring to a boil, then reduce heat to low, cover, and simmer until the potato is fork-tender, about 15–20 minutes.
- Remove the pot from the heat. Stir in the parsley leaves and stems. Let the soup cool for 5 minutes (this helps preserve the bright green color).
- Using an immersion blender, puree the soup until completely smooth. Alternatively, transfer to a blender in batches, filling it no more than halfway, and blend with the lid slightly ajar to let steam escape. Return the pureed soup to the pot.
- Stir in the heavy cream, salt, and pepper. Warm over low heat for 3–5 minutes, but do not let it boil. Taste and adjust seasoning.
- Ladle into bowls and garnish with a swirl of cream, a sprinkle of black pepper, and fresh parsley if desired. Serve hot.
Tips
- Use flat-leaf parsley – Curly parsley is milder and less flavorful; flat-leaf (Italian) parsley gives a more robust taste and smoother texture.
- Don’t overcook the parsley – Adding it at the end and cooling slightly before blending keeps the soup bright green and fresh-tasting. Overcooking makes it dull and bitter.
- Blend carefully – If using a regular blender, never fill it more than halfway with hot liquid, and hold the lid down with a towel to prevent splatters.
- Adjust thickness – For a thinner soup, add extra stock or water. For a thicker, richer version, reduce the cream or add an extra potato.
Serving Suggestions
Serve this soup as a starter with crusty bread or garlic toast. It also pairs well with a simple green salad and a poached egg on top for a light lunch. For a heartier meal, offer it alongside a grilled cheese sandwich or a slice of quiche.
Variations
- Vegan version: Replace butter with olive oil and swap heavy cream for full-fat coconut milk or a splash of unsweetened oat milk. The flavor will be slightly different but still creamy.
- Add greens: Mix in a handful of spinach or arugula with the parsley for extra color and nutrients.
- Herb twist: Replace half the parsley with fresh basil or cilantro for a different herb profile.
- Spicy kick: Add a pinch of red pepper flakes or a small diced chili with the onion for heat.
Storage and Reheating
Store leftover soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop over low heat, adding a splash of stock or water if it has thickened. You can also microwave individual portions in 30-second bursts, stirring in between. This soup can be frozen for up to 3 months; thaw overnight in the fridge before reheating. Note that the cream may separate slightly after freezing—whisk well while reheating to bring it back together.
Frequently Asked Questions
Can I use dried parsley? Dried parsley won’t work well here—it lacks the fresh, vibrant flavor and will turn the soup powdery. Stick with fresh parsley for the best result.
Why is my soup bitter? Bitterness usually comes from overcooking the parsley or using the thick, tough stems. Use mostly leaves and tender stems, and add the parsley at the end as directed.
Can I make this soup ahead of time? Yes, you can make it a day ahead. Reheat gently and add a little extra cream or stock if needed. The color may fade slightly, but the taste will be fine.
Is this soup gluten-free? Yes, as written it is naturally gluten-free. Just double-check that your stock is gluten-free if you have celiac disease.
Can I use a regular blender instead of an immersion blender? Absolutely. Just let the soup cool for a few minutes, then blend in batches, filling the blender no more than halfway. Vent the lid to allow steam to escape.
What can I use instead of heavy cream? Half-and-half, whole milk, or a dairy-free milk like coconut milk will work. For a richer soup, use crème fraîche or mascarpone.
