What Makes This a Gluten Free Cauliflower Soup?
Many creamy soups rely on flour-based roux or thickeners that contain gluten. However, this Gluten Free Cauliflower Soup skips the flour entirely. Roasting the cauliflower first enhances its natural creaminess, so all you need is a blender to get that smooth texture. Plus, all ingredients—from the broth to the seasonings—are naturally gluten free.
Always double-check your broth or stock label to ensure it doesn’t contain hidden gluten. But beyond that, this recipe is naturally compliant and safe for those avoiding gluten.

4 cups vegetable broth (gluten free)

How to Make Gluten Free Cauliflower Soup Step-by-Step
Step 1: Roast the Cauliflower
Preheat oven to 425°F (220°C). Toss the cauliflower florets with 2 tablespoons of olive oil and a pinch of salt and pepper. Spread evenly on a baking sheet and roast for 25–30 minutes, flipping halfway, until golden brown and caramelized.
Step 2: Sauté the Aromatics
While the cauliflower roasts, heat 1 tablespoon olive oil in a large pot over medium heat. Add chopped onion and cook for 5–7 minutes until soft and translucent. Stir in minced garlic and cook for another 1–2 minutes.
Step 3: Combine and Simmer
Add the roasted cauliflower to the pot along with 4 cups of vegetable broth. Bring to a boil, then reduce to a simmer for 10 minutes. This helps the flavors meld beautifully.
Step 4: Blend Until Creamy
Remove the pot from heat. Carefully transfer the soup to a blender (or use an immersion blender in the pot) and blend until smooth. Add lemon juice and season with salt and pepper to taste.
Step 5: Serve and Garnish
Ladle into bowls and top with your favorite garnishes: fresh herbs, seeds, or even a dollop of coconut yogurt for extra creaminess.
