This lightly creamy asparagus soup is bright with lemon and packed with herbs and veggies. It's the perfect fresh meal for a cool spring night.
On rainy spring afternoons, I hole up in the kitchen and make this asparagus soup recipe. It’s my spring substitute for the butternut squash soup I love making in the fall. When it’s too wet to be outside, I find it soothing and meditative to simmer a pot of asparagus soup on the stove and listen to the rain pattering on the roof.
To me, it’s the perfect spring soup. Fresh basil makes it aromatic and refreshing, peas lend it a subtle sweetness, and blended potato makes it lightly creamy without any heavy cream. Serve it as a starter with dinner, or, like me, enjoy it for lunch with a thick slice of crusty bread.
Asparagus Soup Recipe Ingredients
I like to think of this recipe as an extra-bright, extra-green take on classic cream of asparagus soup. Instead of using nuts or dairy to achieve the smooth texture, I blend in Yukon gold potato, which gives it a delicious, lightly creamy consistency. Here’s what else you’ll need to make it:
- Asparagus, of course! Make sure to snap the woody ends off your bunch of asparagus before making this recipe. You only want the tender asparagus tips and stalks in your soup.
- Peas – They add to the creamy texture and balance the asparagus’s vegetal flavor.
- Scallions and garlic – For sharp, savory depth of flavor.
- Lemon juice and zest – They make the soup nice and bright.
- Dijon mustard – For tang.
- Fresh basil – It gives the soup a vibrant, aromatic finish.
- And salt and pepper – To make all the flavors pop!

How to Make Asparagus Soup
Another thing I love about this asparagus soup? It’s quick and easy to make! Here’s how it goes:
- First, sauté the aromatics. Because we’re using scallions and not heartier onions or shallots, this step is fast. They should soften in just 1 or 2 minutes.
- Next, simmer. Stir in the potatoes, garlic, salt, pepper, and water. Bring to a boil, reduce the heat, and simmer for 12 minutes, or until the potatoes are tender.
- Then, simmer some more! Add the chopped asparagus, and simmer for another 5 minutes. The asparagus should be tender, but still bright green.
- Finally, blend. Allow the soup to cool slightly before stirring in the peas and transferring everything to a blender. Add the lemon zest, juice, and mustard, and blend until the soup is creamy. Last but not least, blend in the basil, and season to taste.
Asparagus Soup Serving Suggestions
I serve this soup straight from the blender, when it’s warm, but not piping hot. That way, the bright flavors stay vibrant and don’t become muddled.
The soup is delicious on its own, but I like it even better with a mix of chopped pine nuts, mint, and red pepper flakes on top. They add the perfect blend of crunch, freshness, and heat. If you prefer, you could top your bowl with homemade croutons for crunch instead.
As I mentioned above, I love eating this asparagus soup with crusty bread for lunch. It also pairs nicely with a sandwich, like my Egg Salad or Chickpea Salad Sandwich, or a salad, like my Carrot Salad, Kale Salad, or Strawberry Salad. Of course, a Simple Green Salad would be a great choice too.
If I’m making this asparagus soup for dinner, I usually serve it as a starter. It’s a refreshing first course for spring pasta recipes like these:

Wow!!!! This soup is incredible! It’s FULL of fresh garden flavors. The basil adds so much. I’m super happy I made the topping too. Love the mint. I will definitely make this again.
I’m so glad you enjoyed it!
I love this recipe and wonder if I can freeze the soup.
Hi Janice, yes, it should freeze well.
I used an immersion blender instead of a stand alone. I also added an extra cup of water. Mine looks more like a green purée then it does a soup. Is this normal? Did I do something wrong?
Hi Gina, it’s a pureed soup, like in the picture.
Too much lemon, ruined the flavor.
lovely soup, thank you, and really like the mint and pine nuts!
This soup is amazing! I left out the dijon mustard but I may try it next time. I also didn’t have any basil on hand but it still turned out great. I will be making this again and again. Thank you so much for this delicious recipe 🙂
Hi Anna, I’m so glad you enjoyed it!
I made this and it was delicious! Instead of pureeing the entire soup, I only pureed half (including most of the potatoes) with all of the basil and added it back into the soup. The flavor was outstanding and the texture of the creamy soup with chopped veggies was perfect.
Hi Sara, I’m so glad you enjoyed the soup!
interesting soup, have never made asparagus soup! Mint flavors are nicely different too, thank you
I’m very surprised about your asparagus soup, you don’t strain it? I have never made it without straining it.
Mine turned out perfectly creamy with nothing to strain out.
