Cauliflower Soup

No ratings yet
I learned the hard way that steaming cauliflower leaves it with a sulfurous edge that clashes with creamy soups. Roasting it first caramelizes the natural sugars, creating a nutty depth that blends into something far richer than anything boiled. This method eliminates the "vegetable water" taste and gives you a velvety texture without relying on heavy cream.

Ingredients
  

Roast the cauliflower
  • 1 head cauliflower cut into florets
  • 2 tbsp olive oil for roasting
  • salt and freshly ground black pepper to taste
Sauté aromatics
  • 1 medium yellow onion diced
  • 1 tbsp olive oil remaining
  • 2 cloves garlic minced
Combine and simmer
  • 4 cups vegetable broth
  • 1 tsp smoked paprika
  • 1/2 tsp dried thyme
Finish and serve
  • 1/2 cup heavy cream or half-and-half optional for richness
  • salt and freshly ground black pepper to taste adjusted after blending
  • Fresh chives chopped for garnish

Method
 

  1. Roast the cauliflower: Preheat your oven to 400°F (200°C). Toss the cauliflower florets with 2 tablespoons of olive oil, salt, and pepper on a large baking sheet. Spread them out in a single layer so they roast rather than steam. Roast for 25-30 minutes until tender and deeply browned at the edges.
  2. Sauté aromatics: While the cauliflower roasts, heat the remaining 1 tablespoon of olive oil in a large pot or Dutch oven over medium heat. Add the diced onion and cook for 5-7 minutes until softened and translucent. Add the garlic and cook for another minute until fragrant.
  3. Combine and simmer: Carefully add the roasted cauliflower (and any juices from the pan) into the pot with the onions. Pour in the vegetable broth, smoked paprika, and thyme. Bring to a boil, then reduce heat to low and simmer for 10 minutes to let flavors meld.
  4. Blend until smooth: Remove the pot from heat. Use an immersion blender to puree the soup directly in the pot until completely smooth. If you don't have an immersion blender, carefully transfer half to a standard blender, blend until smooth, and return it to the pot. Note: Always vent blenders when blending hot liquids.
  5. Finish and serve: Stir in the heavy cream if using. Taste and adjust seasoning with more salt or pepper as needed. Ladle into bowls and garnish with fresh chives before serving immediately.

Notes

I keep this in my regular rotation because it comes together while I chop other things for dinner. The secret is deglazing the roasting pan with broth to catch every browned bit; that fond is pure flavor gold. It’s sturdy enough to hold up against a crusty loaf but light enough to not weigh you down.
