Hay fever aside, I love all the blooms, the pretty flowers, and the abundance of asparagus that I can find at the market in the springtime. It’s one of my favorite vegetables, and I’ve already been getting my fill.

I use asparagus in my spring vegetable risotto and asparagus goat cheese frittata regularly when it’s in season, but I’d never used it in soup until about a month ago. It was a hit with everyone in the family, so I knew I needed to share it here.

This soup includes just a few simple steps. It starts by blanching the asparagus tips, which are used to garnish the soup (or enjoy whichever way you like).

From there, the stalks are sautéed with the leeks and garlic, then they’re simmered in vegetable stock until tender. The last step is puréeing the soup, then it’s finished with lemon juice and cream.

This creamy asparagus soup is truly spring in a bowl. It’s so fresh and flavorful, and I love how easy it is to make!

Recipe ingredients

Aspragus leek soup recipe ingredients
  • Asparagus. There are 2 bunches of asparagus in this recipe, which are roughly 2 pounds. Be sure to use the freshest asparagus available. It should have a bright green color with tight tips, and the stalks should be heavy with no wilting.
  • Leeks. Leeks are onions with a very mild flavor, and they truly complement the asparagus. They may be substituted with other varieties of onion such as white, yellow, or shallots.
  • Butter. Butter adds a nice depth of flavor to the soup, but it may be substituted with oil for a dairy-free option.
  • Heavy cream. The cream isn’t a must as the soup is delicious without it, but it adds a nice richness and body that I love.
  • Vegetable stock. Sub with chicken stock if desired.
  • Lemon. The lemon is a must in this recipe as it really brightens the flavors!
  • Chives. Chives are used as a garnish to add freshness and flavor, but they may be substituted with freshly chopped parsley or your favorite herbs.

See the recipe card below for the full list of ingredients and quantities.

How to make asparagus leek soup

This leek and asparagus soup may seem fancy and elegant, but it’s extremely easy to make! Nobody really needs to know. 🙂

Pro tip: Choose the freshest asparagus possible for maximum flavor. The stalks should be firm and heavy with no wilting or discoloration.

See the recipe card below for full recipe instructions.

How to make asparagus leek soup collage
  1. Blanch the asparagus tips. This takes just a couple of minutes in boiling water. Immediately shock in ice water to cool.
  2. Sauté the leeks and garlic. I used my Dutch oven to make this soup, but any heavy-bottomed pot will do.
  3. Add the vegetable stock and bring to a boil. Then, add the asparagus stalks (NOT the blanched tips!) and simmer until they’re tender.
  4. Purée the soup. I find this easiest to do with an immersion blender. Once the soup is smooth, add the lemon juice, heavy cream, and season with salt and freshly ground pepper to taste.

Recipe FAQs

What’s the easiest way to trim asparagus?

For this creamy asparagus and leek soup, the woody, fibrous bottoms must be removed, and the tips are also removed and reserved for a soup garnish. Instead of snapping off each end one by one, use my simple hack below to save time!

1. Snap off the woody bottom of one stalk of asparagus at its natural breaking point by holding it in the middle with one hand and snapping the bottom off with the other.

2. Keep the top rubber band on the bunch, then line up the stalk with the snapped bottom with the rest of the bunch. From there, cut the remaining bottoms off at the same point

3. Line up the tips and cut to remove.How to cut asparagus collage

Can you eat the woody ends of asparagus?

The woody ends of asparagus are tough and fibrous, so they’re not really edible.

How long will the soup last? Can it be frozen?

It will keep in the refrigerator for up to 5 days.

Or, freeze the soup for up to 3 months. When ready to use, defrost overnight in the refrigerator then gently reheat over medium heat until warmed through.

Can the soup be made without heavy cream?

Yes, canned coconut milk may be substituted for a vegan and dairy-free option.

Serving suggestions

We love pairing this smooth asparagus and leek soup with some crusty bread for dipping and a simple side salad.

Recipe notes

  • Pro tip: I saved all of the asparagus tips for garnish, but only a few are really needed. Reserve as many as you like, and add the rest to the soup.
  • This asparagus soup is creamy and luxurious even without any cream, so feel free to omit it to make it. The butter may substituted with oil and the cream may be subbed with coconut milk to make this recipe vegan and dairy-free. 
  • Wash the leeks thoroughly to remove any sand hidden in their layers.
