This ultra-creamy Asparagus Leek Soup tastes like spring in a bowl. Smooth and silky, it highlights fresh lemon and chives with just enough cream for a luxurious finish. This vegetarian soup is simple to prepare and full of bright, seasonal flavor.
When asparagus appears at the market each spring, I always stock up. I love using it in risottos, frittatas, and now this soup. The recipe starts by blanching a few asparagus tips to use as a vibrant garnish. The remaining stalks are sautéed with leeks and garlic, simmered in vegetable stock until tender, then puréed until silky. A squeeze of lemon and a splash of cream finish the soup, balancing richness with brightness.
This asparagus and leek soup is fresh, indulgent, and surprisingly easy—perfect for a light lunch or elegant starter. It stores well in the refrigerator for several days and freezes nicely for later use.

How to make asparagus leek soup
This leek and asparagus soup feels fancy but is very straightforward. Use the freshest asparagus you can find for the best flavor.
Pro tip: Pick asparagus with firm stalks and tight tips; avoid wilting or discoloration.
Full step-by-step instructions are in the recipe card below.
- Blanch the asparagus tips. Boil briefly, then shock them in ice water to preserve color and texture. Reserve for garnish.
- Sauté the leeks and garlic. Use a heavy-bottomed pot or Dutch oven and sweat the leeks in butter or oil until softened, then add garlic briefly.
- Add stock and simmer. Pour in the vegetable stock and add the asparagus stalks (not the reserved tips). Simmer until tender.
- Purée and finish. Purée until smooth using an immersion blender or a countertop blender. Stir in lemon juice, cream (or coconut milk), and season with salt and freshly ground pepper. Serve warm, garnished with chopped chives and the reserved tips.
Recipe FAQs
To avoid trimming each stalk individually, snap the woody end off one stalk at its natural breaking point. Keep the top rubber band on the bunch, line up that snapped stalk with the others, and cut the rest at the same point. Trim and reserve tips separately for garnish or add them to the soup.
The woody bottoms are tough and fibrous, so they are typically discarded.
Store the soup in the refrigerator for up to 5 days. Freeze for up to 3 months; thaw overnight in the refrigerator and reheat gently on the stove.
Yes. Substitute canned coconut milk to make a vegan and dairy-free version; the soup will still be creamy and flavorful.
Serving suggestions
This silky asparagus and leek soup is lovely with crusty bread for dipping and a simple salad. A few ideas:
- Serve with homemade focaccia or other crusty bread.
- Pair with a spring salad featuring berries, greens, or farro.
- Use as an appetizer before seasonal mains such as grilled chicken or salmon.
Recipe notes
- Pro tip: You only need a few reserved tips for garnish; add the rest back into the soup if you prefer.
- The soup is luxurious even without cream. Use oil instead of butter and coconut milk instead of cream to make it vegan and dairy-free.

Creamy Asparagus Leek Soup Recipe
Equipment
- 5-1/2 Quart Dutch oven or similar heavy-bottomed pot
- Immersion blender (or blender/food processor)
Ingredients
- 2 pounds asparagus
- 2 tablespoons unsalted butter (or oil for vegan option)
- 2 large leeks, white and light green parts only, halved and sliced
- 4 cloves garlic, minced
- 4 cups vegetable stock (add more if needed)
- 2 tablespoons fresh lemon juice (about 1/2 lemon)
- 1/2 teaspoon kosher salt, or to taste
- 1/4 teaspoon freshly ground black pepper, or to taste
- 1/3 cup heavy cream (or coconut milk for vegan option)
Instructions
Cut and prep the asparagus
- Remove the bottom rubber band from both bunches, leaving the top band in place. Snap the woody end off one stalk to find the natural break point.
- Line up the stalks and cut the bottoms off at that same point. Trim the tips and set them aside for garnish. Cut the stalks into 1–2″ pieces.
Prepare the asparagus soup
- Bring a medium pot of water to a boil. Add the reserved asparagus tips and cook 2–3 minutes until just tender. Transfer to an ice bath to cool, then drain.
- In a large soup pot or Dutch oven, heat the butter over medium. Add the leeks and cook about 5 minutes until softened. Add the garlic and cook 30 seconds more.
- Pour in the vegetable stock and bring to a boil. Add the chopped asparagus stalks and simmer 8–10 minutes until tender.
- Remove from heat and purée with an immersion blender or in batches in a blender. Stir in lemon juice, salt, pepper, and heavy cream (or coconut milk). Adjust seasonings and serve warm, garnished with chopped chives and the blanched tips.
Notes
- Pro tip: Reserve only a few asparagus tips for garnish; add the rest back into the soup if you prefer.
- The soup remains creamy without heavy cream. Substitute oil for butter and coconut milk for cream to make it vegan.
- This recipe keeps up to 5 days in the refrigerator or up to 3 months frozen.
