Cream of Cauliflower Soup is oil-free, nut-free, plant-milk-free, and soy-free. Savory and delicious, creamy cauliflower soup is packed with vegetables and clearly tastes so good you'll think you're cheating with every delicious bite.
Preheat oven to 400 degrees; line a cookie sheet with parchment paper or a silicone mat.
After chopping and washing the cauliflower, make a single layer of cauliflower on the cookie sheet.
Generously season with garlic powder and onion powder.
Roast for 40 minutes until lightly brown on top.
While cauliflower roasts, saute garlic, leeks, and shallots together in a soup pot.
Add 4 cups organic vegetable broth and stir; reduce heat to medium.
Add chopped potatoes and return heat to medium-high. The potatoes need to cook through.
Add rosemary and nutritional yeast.
Bring to a boil and stir; cover and cook, reducing heat to simmer until the potatoes are soft (30 minutes).
Using a high-speed blender, combine small portions of broth/potato shallot mixture and roasted cauliflower in the blender until smooth. It will be thick but blended without any chunks.
Now return the thick mixture to the soup pot.
Using the remaining 4 cups of organic vegetable broth, add small amounts of broth and stir; the soup will thin out and brighten in color.
