Roasted Cauliflower And Asparagus Soup Recipe – creamy and delicious, this soup is so easy to make and loaded with healthy ingredients. No milk or cream used!


You guys know, with grilling season, I’ve been obsessed with grilled meat and veggies lately. But at least once a week, I do need to make some soup.

My soup recipes are pretty simple – I use a lot of fresh veggies, I usually use vegetable stock, I rarely use cream, they take between 30 minutes to 1 hour to cook and I rarely use a slow cooker.


The combination of cauliflower and asparagus is perfect for spring and summer. And these two vegetables pair perfectly in a soup.

Why roast the vegetables? Flavor… Roasting brings out a lot more flavor than steaming or boiling them.

Growing up, I loved eating cauliflower. I often ate it raw. My grandmother made awesome pickled cauliflower salad, recipe fro which I need to post.

But we never made soup with it. We made salads, stews, or ate it raw. Ever since I started using it in soups, it has turned into one of my favorite vegetables.

But today is all about this Cauliflower And Asparagus Soup.


 This Cauliflower Asparagus Soup is creamy, flavorful and perfect for the times, when you just want to try something different with your favorite vegetables.

  6. I am on an elimination diet and cannot have dairy.  Do you think omitting the Parmesan cheese will affect the soup badly? 


    1. Hi Sandy, I think it should be fine! You can add nutritional yeast as a topping if you’d like, it is dairy free. Let me know!
