    As far as vegan soup recipes go…this one should be on your radar…

    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!  You end up with a healthy comforting bowl of cauliflower soup with top notch flavour!!

    There’s no coconut milk, plant milk or cashews, just partially blending the soup creates such an amazing texture none of the cream options are needed! 

    Lovely for lunch or a lite dinner. Great family meal! Perfect cozy soup for fall, winter or anytime really! My daughter says she wants my potato leek soup next - ahh! wow one at a time sweetie ❤️ lol

    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...

      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.
