Roasted Asparagus, Cauliflower, and Mushroom Soup combines yummy vegetables with a lemon tang and basil kick! Nutritious, comforting, and a wonderful way to welcome spring time!
Happy spring!! I am so excited to bring you guys this delicious bowl of soup during the first few weeks of spring. It’s quite perfect for the weather, really. Can’t tell if we’re going to be warm or cool this week, so this soup fits the bill! I have been patiently waiting for asparagus to be ripe and ready. I love it, and I love all the nutrition it brings to the table. Asparagus packs in the anti-oxidants and anti-inflammatory properties making it one of the absolute BEST vegetables for your body!
Want to know what else? It’s even better when it’s IN SEASON. Asparagus is at its peak in April, but I love it all year round.
So this soup…… I’m thrilled with the way it turned out! I’ve been wanting an asparagus soup for awhile, and was trying to think of a flavoring combo that was just perfect. I spent some time playing around with this soup, and am absolutely in LOVE with the delicious taste! The fresh basil really gives it a bold fresh taste, and lemon adds the perfect amount of acid for balance. The cauliflower also gives it a “creamy” like base.
How to make Roasted Asparagus, Mushroom, and Cauliflower Soup:
We’ll gather up our simple ingredients:
- asparagus
- cauliflower
- avocado oil or olive oil
- onion
- mushrooms
- garlic
- vegetable broth or chicken broth
- lemon
- fresh basil
- salt and pepper to taste
I started by roasting cauliflower and asparagus in the oven.
While they roasted, I roasted the mushrooms with garlic and onion in a large pot on the stove. Once the asparagus and cauliflower were finished, I tossed them in the same pot, and covered everything with some vegetable broth.
Once everything boiled, I blended it all together with lemon and basil. It is also super tasty topped with some pesto, lemon pepper, and even parmesan cheese (it also tastes great dairy-free!)
A quick funny story. So I made this for St. Patrick’s Day; we were celebrating green food and all. My kids don’t love asparagus or mushrooms, but they do love pesto. So I made this earlier in the day, and told them we were eating pesto soup for dinner. They loved it!
Had no idea that asparagus was all pureed in there, nor did they ever suspect mushrooms. I topped it with parmesan cheese and some homemade pesto to give it even more of a “pesto” flavor for them. It was super yummy and highly recommended if you have pesto!

Recipe Notes
I used a pretty large bunch of asparagus, but wasn't sure the exact weight. A bundle of asparagus will work!
I don’t know how to navigate the site. Am looking for a specific recipe that I originally saw on Yummly (Coconut and Pecan Crusted chicken Tenders). Can’t find it.
Hi there! Here is the recipe you are looking for: http://www.wholesomelicious.com/coconut-and-pecan-crusted-chicken-tenders/ You can always use the search window and type in the recipe! Or under the recipe tab, then dinner. Hope this helps!
This soup has got all of my favourites in and sounds delicious! Thanks for sharing.
Thanks Lucy! Hope you enjoy it!!
This soup had a unique flavor. My family enjoyed it, including my 6 year old. It was great to branch out and try something new. Good texture and consistency as well. I followed the directions with the exception of the yellow onion, I used leeks, as that’s all I had on hand. Thanks for the recipe!
Great Charlie! Glad you enjoyed it 🙂
I randomly came across the recipe since we had cauliflower & asparagus in the fridge. I didn’t know what to expect but our family loved it. Our kids had a friend over and he asked for seconds!
So glad to hear that!! Thanks for stopping by 😃
I am a pet sitter who has a meal ready for folks when they arrive home. I try to use what they have left that needs to be used. I was searching for asparagus and mushroom soup and found this. Amazingly, I am also making a Sheperds Pie with mash cauliflower top instead of potato. So I have cauliflower – perfect! I’ll let you know how it turns out.
I need to try this, is this something that is good reheated? I am looking for meal prep ideas and I am hoping this would be good for the week!
Yes, it tastes great re-heated!
I made this a couple of months ago when I had everything but the mushrooms and just pulled a portion out of the freezer. Now in social isolation with no basil, I used a dollop of jarred pesto and freshly grated parmesan. It was fabulous and I send my thanks. Next time there will be toasted pine nuts on top because, well, I’ve got some time on my hands!
Yummm!!! Love that you were able to freeze and have now. And the pesto, parmesan, and pine nuts are all delicious additions!
Made this as described, with a pesto dollop stirred in and it was delicious! Thanks for sharing the recipe.
