    Wow, the title sums the soup right up! Just Incredible! Thank you for sharing this recipe. I had to make a few simple substitutions as I didn't have the items on hand (ran out of carrots, so doubled the celery, and only had celery seed) but this was still crazzzzy delicious and wonderfully healthy to boot! Such depth of flavor. This is now definitely in the family soup rotation. Thank you again for sharing this wonderful recipe.

    Okay… this was insanely delicious. I was pleasantly surprised by how much flavor was packed into the soup with just a few ingredients. My immersion blender freaked out on me, so I left the soup almost entirely chunky, but I like more texture in soups so it worked out. 10/10 and I’ve already shared with my family.

    I will definitely be making this soup for supper tonight but wanted to mention that this recipe is not gluten-free. The Better Than Bouillon product no longer claims to be GF as they make this in a facility where wheat is also used. As well, the yeast extract comes from a grain which has gluten.

    This is delicous. Humble ingredients and a great flavor! My only change was to not add the lemon juice at the end. Just a personal preference , I have realized when I don't care for a recipe it's usually the lemon juice in it that is the reason. Other than that it was made per the recipe. I am definitely putting this in my rotation , and cauliflower will be purchased way more often! lol ( I had no idea I liked roasted cauliflower so much!) Thanks so much for sharing!

    Made this last night and my wife and I both loved it. For some reason I was expecting something a bit creamier, but in the end I wasn't disappointed at all. Followed the recipe almost to the letter, with the exception of omitting the lemon juice (didn't need it), and adding the nutritional yeast at the end, just before serving. My understanding is that nutritional yeast should not be cooked.

    Really enjoyed this! Added one diced red potato w an extra 1/2 c water as I knew my growing teen would like that. Used the roasted garlic better than bouillon, 4 1/2 tsp. Will make again!
