Topped with more roasted vegetables for texture, it’s both filling yet light. Some of my other favorite creamy soups are Leek and Potato Soup, Cream of Asparagus Soup, and Carrot Ginger Soup.

My aunt shared this recipe with me, which she adapted from the Savory magazine she picked up at my local supermarket. At first thought I wasn’t sure how I felt about Brussels sprouts in a soup, but my first spoonful I was in love with the taste! The roasted flavor really comes through in every bite, perfect to warm up on this cold, snowy day.

  1. It’s delicious! I did also add garlic. I also used some flavor God garlic and herb salt and some Adobo but other than that, I followed the recipe and it was absolutely delicious!

  2. If you put the hot liquid in the blender, won’t it blow the lid off? I’ve read never do that so how do I get around it!

  3. I knew this soup was going to be bland. I had a plan since the beginning. I added two cloves of garlic when I roasted the vegetables. I cooked a very small potato with the broth. Instead of salt I added a knorr chicken bouillon, 1/8 teaspoon of ground thyme and 1/8 teaspoon of garlic. And finally I added 1/4 cup of heavy cream. Oh, yes. I am going to make this soup many more times. Absolutely delicious with my changes. Avoid adding the charred leaves. Delicious!!!

  4. OMG! This was so, so good!!! I’ll make it all the time. Really nice way to get those veggies in. I added whole cloves of garlic on the sheet pan with the veggies because I love roasted garlic. 

  5. I pair this with a well salted and peppered perfectly cooked steak.  The soup is almost a purée.  Soooo delicious.  I eat about 4oz of the steak and a massive bowl of soup with roasted veg on top.  Has become my go to indulgent meal.  Guests love it.  Trick is to purée until it’s super smooth and add a little water.   Dip the steak in the thick soup and enjoy.   

  6. So yummy! I made this as directed but added cayenne and red pepper because I like a little spice. I think I will make it again this Fall but add garlic like some reviewers have done and roast extra veggies to top the soup with. Delicious as is but there is definitely room to build up for folks that like more complex flavors.

  7. This recipe is TERRIFIC!! I’ve made it many times, and it’s a hit each and every time. Easy, healthy, and luscious! It’s one of my favorite soups.

  8. Hearty and ridiculously healthy. The cruciferous taste is very strong so I wouldn’t serve it to guests unless I knew they were really into cruciferous… like me! I added garlic and pepper to the vegetables when roasting them and added marjoram, thyme, and summer savory after they were puréed. I didn’t hold out any large pieces and puréed all of it in the pot with a stick blender.
