My vegan cauliflower soup recipe with roasted cauliflower, you will love it! it’s so creamy, super easy and tastes amazing!! It has a lovely hearty chowder consistency without the addition of potatoes and you’ll be hard pressed to believe it’s vegan!
You’ll be amazed that by just roasting the cauliflower, adding a few simple healthy whole food ingredients, carrots, celery, onions, spices, nutritional yeast and my secret flavour ingredient for vegetable stock- better than bouillon vegetable base!

How to make Roasted Vegan Cauliflower Soup:
(for full recipe instructions and ingredients see recipe card at end of post)
Preheat oven to 425° Line a large baking sheet with parchment.
Slice the head of cauliflower down the middle lengthwise and cut out the core. Pull off the florets and cut into slices. Add to the baking sheet. Drizzle over the oil and a pinch of salt and pepper. Toss everything together (I use my hands) and spread evenly on the sheet pan.
Bake for 35 minutes tossing halfway through cooking. When cool enough to handle give it all a rough chop


When the cauliflower is almost finished baking start the soup: Set your soup pot or Dutch Oven over medium heat. Add the onions, carrots, celery and garlic, oil and pinch of salt and pepper. Saute for 5 minutes or so until veggies are softening.
Now add the water, bouillon, nutritional yeast, salt, spices and roasted cauliflower (reserve lemon juice until the end of cooking) Bring to a boil on high heat. Cover reduce to a simmer and cook for 10 minutes or so until the veggies are tender.
Remove 4 big ladles of soup (4-5 cups) and puree in blender. Pour back into soup. Season with salt and pepper, stir in the lemon juice. If soup is too thick add a splash or two of vegetable broth. Enjoy!
Serve with my no knead artisan bread for a tasty lunch or lite dinner!

Really good! Love the roasted cauliflower taste. I blended a can of chickpeas in at the end to give a touch of protein.

This simple soup is worth a try. It very much needs an acidic element, so if you skip the lemon juice, add something else. It's not just a "if you want to" thing. I skipped it bc I don't have any. The result was that the flavors were unbalanced. I realized later that the problem was that it was too heavy on the umami; and I LOVE umami.
I put the soup in the fridge overnight, assuming it would taste better the next day. I reheated it, and added tomato powder and seasonings with citrus peel. Bingo! Balanced.
The simple ingredients, ease, and freezability mean this one is going in the rotation. I see myself adding other veg, like kale, white potatoes, corn...

Giselle says
This soup was FABULOUSLY GOOD! It was so savory. I made it just like the recipe said, no modifications. My husband raved about it. Thank you for sharing it!
Kelsey says
This is DELICIOUS!!! This recipe is so flavorful and soothing. I added one can of white beans for some protein and it blended up perfectly with the other ingredients. Thank you - I’ll be looking out for more soups!!
Linda says
Absolutely delicious! I added chickpeas for a little more protein and jalepeno for a little kick!
DebbieB says
Just finished making this and it is so good. I made it in my Instant Pot and it turned out great. Cooked for 5 minutes with 10 minutes natural release. I thought it might get mushy but it didn't and I used my immersion blender to blend it up a bit and still some slightly chunky cauliflower. A keeper! Thanks much for the recipe!

So delicious! It tastes decadent and rich but the ingredient list is very healthy. A bit of work up front chopping but totally worth it and I'm excited for leftovers this week.
