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. This soup is filling and great tasting. I added a clove or two of garlic on the sheet pan with the veggies, and a few sprigs of fresh thyme and a bay leaf when sautéing the shallots. I also added in some crumbled turkey bacon at the end. So much flavor and hits the spot every time I make it.

    Will be trying this tonight, but there seems to be something missing between 3 & 4. 4 says “shut the oven.”
    If you were roasting the veggies, wouldn’t it have been shut?

  3. This was delicious. The only thing I added was a few cloves of garlic when I was roasting the vegetables and 1 chopped clove of garlic when sautéing shallots. My soup was green like the photo. I made sure not to roast the vegetables too long and charred the vegetables left behind for garnish. I think fresh ground pepper is a must.

  4. Step 4 says shut the oven but there is nothing before than says anything about opening it. Wondering if I’m missing a step. 

    1. I believe after you finish roasting your veggies she just wants you to turn off the oven but keep a small portion to top the soup warm in the oven while you finish up the soup.

  5. I mean WAIT A MINUTE!! This soup is fantastic! Hard to believe that something so simple (and healthy!) can taste this good! I used 3 tsp. of low sodium Better than Boullion Chicken flavor + water instead of veggie broth. Really, really, really good! Will definitely make again…. tomorrow actually, as it’s already all gone!!

  6. I think I roasted the veggies a little too long (though did the specified time) and used onions instead of shallot. Mine was also brown and very thick. It was tasty. Not sure I like it as a soup but I think it somehow makes an awesome vegetarian gravy.

    So creamy and delicious. Easy to make and addictive. Especially yummy in the winter. The first time I made it my daughter was over and we ate all the servings!

  8. Could you roast the shallots with the cauliflower and brussel sprouts to save time and dishes while keeping flavor? Thanks for your input! And while I’m here, thank you for making such a beautiful site with such reliable, delicious, and inspiring meals. I don’t like to cook but I like to eat well so I am a huge fan of how simple, healthy, and delicious your recipes are!

  9. I made this dish yesterday following the Whole 30 recipe and absolutely loved it!!! Great healthy dish. Thank you.

    Very good. Used onion and garlic since that’s what I had on hand and tasted great! Also blended it all since I was using it for lunches.

  11. I’m wondering why this soup isn’t 0 points. It’s all veggies except for some oil…. I substituted oil and didn’t  use butter.

    Very filling, great flavor and super easy to make.  I “rough chopped” all the veg w/my immersion blender  instead of reserving a few whole pieces, but that’s just me being lazy.  I also added a bit more salt than called for (salted veg before roasting & added more to soup) – but we tend to go heavy on salt.  Color wasn’t really appetizing but it did not deter us at all!

  13. Thank you for this delicious soup! Admittedly, I looked at it sideways thinking it couldn’t possibly be that good, but I am stunned on how tasty it turned out. Like the others, mine turned a brown-green, but it tastes so good I don’t care about the color.

    Made this tonight! I used frozen brussels and regular onion and it was still freaking amazing!!! (Made some cornbread to go with it. YUM!)

  15. My daughter and I made this for dinner tonight. It was good!  I put a half tsp of Parmesan cheese and 2 TBS of croutons on top along with the roasted veggies. We enjoyed it. The additions only changed the SP value by 1 point. 

  16. This soup is delightful! Prep really didn’t take very long, and is worth the healthy, filling result. I used chicken broth rather than vegetable, and used a spice mix (Badia) on the veggies before roasting. It was delicious, with a white cheddar and oatmeal bread grilled cheese on the side.
