This asparagus soup tastes rich, yet it’s made without heavy cream – just veggies, broth, and a bit of Parmesan cheese puréed to silky perfection.

One of my favorite soup recipes, this creamy asparagus soup is made without heavy cream—just vegetables, broth, and a bit of Parmesan cheese puréed to silky perfection. It’s perfect for early spring when asparagus is in peak season and there’s still a chill in the air. Serve with a focaccia or a good artisan bread.

How To Make Asparagus Soup

Begin by melting the butter in a large pot. Add the onions and garlic. Cook until soft and translucent, about 8 minutes.

While that’s going, prep the asparagus. Trim off the tips (you’ll use them for a garnish), then cut the remaining spears into 1/2-inch pieces.

Add the chopped asparagus to the pot, along with the chicken broth, salt, and pepper. Bring to a boil.

Cover and simmer for about 30 minutes until the vegetables are very tender. Purée the soup with a hand-held immersion blender until smooth and creamy. Alternatively, you can blend the soup in batches in a blender.

Return the soup to the pot and stir in the fresh lemon juice and grated Parmesan cheese.

Finally, cook the asparagus tips in salted boiling water for a few minutes until tender-crisp.

The best way to preserve the bright green color of the tips and keep them crisp is to shock them in an ice bath, but you can also refresh the tips under cold running water.

Finally, ladle the soup into bowls and top with the asparagus tips, Parmesan cheese, fresh herbs (if using), and freshly ground black pepper.

Asparagus Soup with Lemon and Parmesan

Bowl of asparagus soup with lemon and parmesan.
This asparagus soup tastes rich, yet it's made without heavy cream – just veggies, broth, and a bit of Parmesan cheese puréed to silky perfection.
Servings: 4 to 6
Prep Time: 15 minutes
Cook Time: 40 minutes
Total Time: 55 minutes

Ingredients 

  • 2 bunches asparagus (about 2¼ pounds/1 kg), bottom ends trimmed
  • 3 tablespoons unsalted butter
  • 2 medium yellow onions, chopped
  • 3 cloves garlic, peeled and smashed
  • 6 cups low-sodium chicken broth
  • Salt
  • Freshly ground black pepper
  • 2 tablespoons freshly squeezed lemon juice, from one lemon
  • ½ cup shredded Parmigiano-Reggiano
  • Handful fresh herbs, such as thyme, dill or basil (optional, for garnish)

Instructions

  • Melt the butter in a large pot over medium heat. Add the onions and garlic and cook, stirring frequently, until soft and translucent, about 8 minutes. Do not brown; reduce the heat if necessary.
  • In the meantime, cut the tips off of one bunch of the asparagus and set aside (you'll use those for a garnish). Cut the remaining spears and the other bunch of asparagus into ½-inch (13-mm) pieces.
  • Add the chopped asparagus to the pot (minus the reserved tips), along with the chicken broth, 1 teaspoon salt and ¼ teaspoon pepper. Bring to a boil, then cover and turn the heat down to low. Simmer for about 30 minutes, or until the vegetables are very tender.
  • Meanwhile, bring a small pot of salted water to a boil. Cook the reserved asparagus tips for a few minutes, or until tender-crisp. Drain the tips and then place them in a bowl of ice water to "shock" them—this stops the cooking process and preserves their bright green color. Once the tips are cool, drain them and set aside.
  • Purée the soup with an immersion blender until completely smooth. (Alternatively, use a standard blender to purée the soup in batches, then return the soup to the pot.) Bring the soup back to a simmer and stir in the lemon juice and Parmigiano-Reggiano. Taste and adjust seasoning, if necessary. To thicken the soup, allow it to simmer, uncovered, until the desired consistency is reached.
  • Ladle the soup into bowls, then top each bowl with asparagus tips, Parmigiano-Reggiano, herbs (if using), and freshly ground black pepper.

Notes

Freezer-Friendly Instructions: The soup can be frozen in a tightly sealed container for up to 3 months. Defrost overnight in the refrigerator and then reheat on the stovetop over medium heat until hot. (The soup will freeze best if you add the cheese when reheating.)

    This soup is so simple to make and so delicious. 🙂 Followed the recipe except added a bit more garlic and onions (per my usual).

    Today I had to use up some wonderful fresh asparugus a neighbor gave us. Made this recipe, but cut ingredient amounts down to 1/3 (only had 10 ozs of trimmed asparagus). I purposely went a little light on the lemon. Had a small parmesan rind so did simmer with that. Probably used a bit more onion than called for, and added asparagus tips in with the rest of the asparagus; did not save them for a garnish. The soup was very good. The reduced amount was enough for 2 very generous bowls. So glad I could put the asparagus to good use!

    I over-cooked some asparagus, so I spent twenty minutes turning it into this amazing soup. Everyone raved like it was from a fancy restaurant; it went perfectly with our crab brioche sandwiches. I will absolutely use this fantastic recipe again.

    Made the recipe as given and it was delicious! Thank you!

  • I simmered asparagus stems in broth with onions last night and this morning looked for recipes to salvage it (brought back some painful childhood memories of boiled asparagus…) I did not exactly follow your recipe, but did add in all your extra ingredients except lemon. It took a lot to ultimately eliminate the boiled asparagus flavor and make tasty.

    I really only came to add that I want to try the recipe as written and also experiment with using preserved lemon. Thanks for the direction!

    This soup was delicious
    I did make several adjustments
    I only used one bunch asparagus and added 1 cup of cooked rice before puréing with immersion blender made soup thicker and creamier

    Good morning Jenn,
    I have made many of your wonderful recipes and they all were delicious. Unfortunately I must’ve done something wrong as this didn’t turn out well. I cooked my asparagus for over an hour and the veggies were soft and well done. I used my immersion blender repeatedly and every time I picked it up, there was a lot of “mush” on the bottom of the blender. Then used a large spoon and kept stirring but that didn’t help. I had a bowl of it and the soup was very stringy. Before refrigerating it, I had to use my colander to strain all of the thick “mush” from the soup.
    I wish I knew what went wrong.
    Susan

    • Hi Susan, I’m sorry you had such a problem with this! It sounds like you blended it thoroughly. Did you make any adjustments to the recipe? If not, asparagus can be fibrous, but I wonder if perhaps yours was really fibrous. You did the right thing by using a strainer to get the “mush” from the soup, but sorry it was a disappointment!

    • It sounds like you did something wrong. It did not deserve a 1 star rating. It’s a delicious soup. Please try again with maybe a different blender.

      I re-read the instruction after your comment and realized the many times an instruction is added to snap off the Woody ends. I thought maybe you are new to asparagus and the variance in Woody/fibrous ends. That’s would explain your result. Technique is to bend near end inching up a little til it snaps off.
      Using this recipe for Christmas dinner tomorrow. I already know I’ll love it.
      Grew my own for a few years, big asparagus soup find. This time it gets a standing rib roast to go with it.
