This roasted asparagus soup recipe is creamy, cozy, and bursting with fresh flavor thanks to roasted garlic, a splash of cream, and lemon juice. It’s light, easy to make, and perfect for spring!
Like my roasted tomato soup and creamy mushroom soup, roasting the veggies takes the flavors in this soup to a whole new level. All you need is a crispy air fryer grilled cheese on the side.
When spring rolls in and fresh asparagus is everywhere, I always grab a few extra bundles to make this creamy, cozy roasted asparagus soup. It’s super simple, but full of depth thanks to the magic of roasting! Just asparagus, garlic, a splash of cream, and a few seasonings come together to make something so silky and good.
Why This Roasted Asparagus Soup Recipe Just Works
- Roasting brings out the flavors. This soup is based on my original asparagus soup, but roasting the veggies first takes the flavor to a whole new level. Plus, I throw in some extra garlic because, well… it’s me. 😄
- Use up leftovers. Soups are a wonderful way to use up leftover roasted or grilled asparagus. I always make this asparagus soup when I need to use up those extra stalks sitting in the fridge.
- Versatile. Whether I make it as a light lunch, a dinner party starter, or just to have in the fridge for last-minute meals, this roasted asparagus soup is one of those easy recipes that always surprises people with how flavorful it is.
Gather Your Soup Ingredients
This roasted asparagus soup doesn’t need much, just a few easy fridge ingredients that I’ll cover below. Scroll down to the full, printable recipe card, followed by a step-by-step overview after the post.
- Asparagus – I’ll show you how to roast asparagus to bring out a deeper, richer flavor. Fresh is best; please don’t use asparagus from a jar.
- Garlic – Feel free to use garlic powder if you’re out of fresh garlic. Start with ½ teaspoon and adjust to taste.
- Olive Oil – Helps everything roast up, but you can swap in avocado oil or any neutral cooking oil if needed.
- Vegetable Broth – Chicken broth works, too. I recommend low-sodium broth or stock so you can season the soup to taste.
- Heavy Cream – Makes the soup creamy and luxurious. Half & half works if you want to lighten it up.
- Lemon Juice – Brightens the whole dish and cuts through the richness. I recommend using fresh lemon juice, but bottled works in a pinch.
- Fresh Parsley – Optional, but so worth it. Adds color, texture, and a final pop of freshness. You could also use basil or thyme.
- Shredded Cheddar or Parmesan – Sprinkle a little on top for a cheesy finish.
Recipe Tips and Variations
- Sauté or, in this case, roast the aromatics. This develops more complex and delicious flavors, as well as softens the vegetables. If you don’t want to switch on the oven, consider sautéeing or steaming the asparagus on the stovetop instead.
- Keep the soup at a simmer. Simmering heats the soup more gently and evenly. Boiling can cause the heavy cream in the soup to split.
- 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.
- Easy add-ins. Add pepper flakes for a spicier kick, and 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 soup.
What to Serve with Asparagus Soup
I like to serve my roasted asparagus soup with something light but satisfying, like my baked lemon chicken. Or serve this springtime soup as a starter before our Easter rack of lamb. This creamy soup also goes great with pesto salmon or garlic butter salmon. Serve with a side of crusty, no-knead skillet bread or thick slices of homemade focaccia for dunking.

Notes
- Asparagus: Make sure to snap off the woody ends, or your soup will be stringy and inedible.

- Salt to taste: Taste the soup and adjust the salt to your liking before serving. You may also want to add more pepper and lemon juice.
- Parmesan cheese: For more flavor, whisk in grated parmesan cheese.

How to Make Roasted Asparagus Soup
Roast, blend, heat, and serve! That’s it. Those are the steps. This creamy roasted asparagus soup couldn’t be easier to make, and I’ll walk you through it:
First, Roast the Asparagus
- Prep. First, break off the tough ends on the asparagus stalks. Then arrange the asparagus on a foil-lined baking sheet.
- Roast. 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.
Blend the Soup
- Blend. Remove the asparagus and garlic from the oven and transfer them all to a blender. Add the broth and cream, and process the soup until everything is blended and smooth.
- Heat it. Now, 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 you reach your desired consistency.
- Finish and serve. Lastly, whisk in the lemon juice and taste for salt and pepper, adjusting to your liking. Ladle the asparagus soup into bowls, garnish with parsley and cheese, and serve!
How to Store & Reheat Leftovers
- Refrigerate. Once the soup has cooled, store it in an airtight container and keep it in the fridge for up to 4 days.
- 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.
- Reheat. Set the soup over low heat and gently reheat it, occasionally stirring, until it is warmed through.
Hi! I am wondering if the garlic should be roasted with the asparagus or not. The title is “Roasted Garlic…” but I don’t see instructions for roasting the garlic.
Hi Karen!! I’m sorry, I should have stated that. Yes, it should be roasted together with the asparagus. Toss asparagus and garlic with olive oil, season with salt and pepper, and arrange on prepared baking sheet in one layer. Thank you, Karen!
Can I use my immersion blender to blend the asparagus mix?
Thank you in advance.
Hi Amber!! Yes, absolutely! Hope you enjoy the soup! :))
I have a dairy, nut and soy allergy so I made it with organic unsweetened coconut milk… I also didn’t have enough asparagus so I roasted some zucchini with it to make up the difference . It was delicious and got 2 thumbs up from my husband as well!
How do you think this would taste with almond milk rather than cow’s milk? Looking for a vegan asparagus soup is harder than I expected.
HI! Actually, it tastes really good! I’ve made it with soy milk and almond milk – the taste was still amazing. 🙂
HOLY AMAZING! Ok I will admit I wanted to make a double batch and didn’t have enough asparagus, so I added in frozen peas- but the garlic/green veggie combo is amazing. I also used my immersion blender rather than the blender. Can’t wait to see what my guests think tonight.
Making this tonight–and it smells AMAZING. Thing is, we’re having it as a main course–so we are wondering the number of servings! Can you let us know, please? PS: I made croutons! 😉
Hi Jennifer!! A regular, pre-main-meal serving size of soup is 8 ounces, or a cup, but since it’s the main course, I’d for sure go and get me a cup more. hehe 😀 And it’s still under 200 calories.
Major high-fives on the homemade croutons, though!
Hope you enjoy it! Let me know how it goes!
OH! And the whole thing is about 8 cups. 😀
I love how easy this soup is to make!
This soup is so gorgeous Kate! And that color – wowza!
This soup is so gorgeous I am obsessed! I need to try asparagus like this, it’s genius!
Delicious!!!
Ahhh! This soup has me dreaming of summertime! Want!
