Easy Roasted Asparagus Soup Recipe

Put that fresh asparagus to good use in this beautiful creamy roasted asparagus soup! Asparagus and garlic are roasted, pureed, and combined with cream and seasonings to create all the silkiness going on up in there. I LOVE IT!

This soup was inspired by my creamed asparagus soup. The two recipes are very similar but this one has the added step of roasting the asparagus, which creates a more robust flavor. I added some extra garlic too.

Asparagus is a delicious and versatile vegetable that is packed with nutrients. It is also a good source of vitamins and minerals, including vitamins A, C, E, and K, as well as folate, fiber, iron, and potassium. Asparagus is also rich in antioxidants. It’s a superfood!

But what matters here is that asparagus is also an excellent addition to any meal and can be used in various ways. One of the best ways to enjoy asparagus is by making soup, IMHO.

What You’ll Need

  • asparagus: ends trimmed

  • chopped fresh parsley: for garnish
  • shredded cheddar cheese: for garnish

How to Make Creamy Roasted Asparagus Soup

  • First, break off the tough ends on the asparagus stalks. Then arrange the asparagus on a foil-lined baking sheet.
  • Smash ten cloves of garlic, add them to the baking sheet with the asparagus, and toss everything together with salt, pepper, and oil.
  • Roast in the oven at 450˚F for 10 to 12 minutes or until the asparagus is tender.
  • Remove from the oven and transfer the asparagus and garlic to a blender.
  • Add the broth and cream to the blender; process until everything is blended and smooth.
  • Transfer the soup to a pot and set it over medium-high heat. If the soup is too thick, add more vegetable broth, about 1/4 cup more at a time or until desired consistency.
  • Whisk in the lemon juice. Taste for salt and pepper, and adjust to your liking.
  • Ladle the soup into bowls, garnish with parsley and shredded cheese, and serve.

Tips and Variations for Successful Soup

  • Sauté or, in this case, roast the aromatics. This develops more complex and delicious flavors, as well as softens the vegetables.
  • Keep liquids at a simmer. Simmering heats food more gently and more evenly.
  • Add salt. This does not mean making the soup salty, but the saltiness of the broth and all other ingredients can vary greatly, so it’s always best to taste for salt, pepper, and other seasonings and adjust to your taste.
  • Add pepper flakes for a spicier kick.
  • Stir in grated parmesan cheese for more flavor.
  • Whisk in fresh lemon juice. Lemon juice brightens and balances the salty and rich flavors of the dish.

What to Serve with Roasted Asparagus Soup

How to Store & Reheat Leftovers

  • To Refrigerate: Once the soup has cooled, store it in an airtight container and keep it in the fridge for up to 4 days.
  • To Freeze: Store the soup in freezer-friendly bags or containers and freeze it for 2 to 3 months. Note that freezing this Asparagus soup may cause the texture of the soup to change.
  • To Reheat: Set the soup over low heat and gently reheat it, occasionally stirring, until it is warmed through. Avoid boiling the soup or reheating it in the microwave, as this can cause the cream to separate and the soup to become grainy.

  1. I was skeptical about adding the lemon juice like a previous person, but the flavor profile is outstanding, although I used heavy cream in place of the half and half. I Would definitely recommend this recipe, and make it again.

  2. I just made this for the first time. It’s a little too thin for my taste and a little bland. I did use coconut cream to make this a little more heart healthy. I think I will try this again. However I will use more cream and less broth, add an onion and some Parmesan as someone else had suggested in the comments. Any suggestions on a spice/herb or two to add more flavor without adding heat?

  3. So I am not a soup fan but love making different soups for my diabetic husband during the cold weather months for lunches. Garlic and asparagus are his favorites. I left out the lemon, used a whole head of garlic, I added a small onion, a can of chick peas for protein and 1/2 a cup of pine nuts to add a bit of substance to the creamy soup. I also sent him with a small bag of shaved parmesan to add to the top after heating it. He loved it! This was the one recipe he did not add any extra seasoning to! Thank you for the base of a keeper of a recipe!

      So yummy! I swapped the cream with unsweetened almond milk to keep it extra healthy. I also added a touch of dried tarragon at the end (would have used fresh, but didn’t have any) Tarragon and asparagus go great together. And a fresh squeeze of lemon 🍋 when you put the soup into your individual serving bowls is key. Otherwise it can taste a little flat.

  4. Any reason why mine has milky chunks in it? The asparagus was not right out of the oven when I blended it…Disappointing..

    1. I know this was long ago, but if you used milk instead of cream, adding it to the hot soup can cause it to curdle. Not dangerous, but not appetizing. Another possibility is that you used cream and overblended, essentially turning it into whipped cream. I make cream soups all the time, and both of these problems can be corrected by adding milk or cream after pureeing, and just slowly warming it through.

  5. I really like this soup – the flavor is spot on. However, even after blending it for 30 seconds or so it still had pieces of asparagus in it. How long do recommend blending it?


  6. I clearly did something wrong! I noticed you said that if you want to thin it down you could add more broth. I am trying to figure out how to thicken the soup. I realize that it would no longer be 6 SmartPoints, but I think I would add 2 tbl spoons of cream cheese to try to thicken this soup. I have a lot of thin soup to eat as my husband told me he would find something else for dinner.

    1. I really wanted to love this recipe, but I just didn’t. I was looking through the comments to see if anyone else felt that way, and what they did to make it better, when I saw your comment. Spot on! I was hesitant and doubtful about adding lemon juice, but this really did the trick! It doesn’t taste lemony, but it really tempered the flavor and I’m soup-er happy (see what I did there ). Thanks for the tip!

      Hi! Yep, you can freeze it. Transfer the cooled soup to a covered airtight container, or you can also use heavy-duty freezer bags. Stir the soup really good when reheating it just so to prevent it from curdling.
