Description

Roasted Cauliflower Soup is a smooth, creamy, and deeply flavorful dish with a fluffy curry cream topping. It’s the perfect cozy meal for fall or winter, and easy enough for weeknight dinners.


Ingredients

Scale

For the Soup:

2 large heads of cauliflower (about 4 lbs), cut into 1-inch florets

9 tbsp extra-virgin olive oil, divided

Kosher salt, to taste

1 medium yellow onion, thinly sliced

1 celery stalk, thinly sliced

3 garlic cloves, smashed

1 large sprig fresh sage

4 cups chicken or vegetable broth

3/4 cup heavy cream

Freshly ground black pepper, to taste

For the Curry Cream:

1/2 cup heavy cream

1/2 cup sour cream

2 tsp curry powder

Kosher salt, to taste


Instructions

  • Preheat and Prep: Heat your oven to 500°F (260°C) with racks in the upper and lower thirds. Spread cauliflower florets across two rimmed baking sheets. Drizzle with 6 tablespoons of olive oil, season with salt, and toss to coat. Arrange in a single layer.
  • Roast the Cauliflower: Roast for 25 minutes, flipping halfway and switching tray positions, until golden brown and caramelized.
  • Sauté the Aromatics: In a large saucepan, heat the remaining 3 tablespoons of olive oil over medium-high. Add onion, celery, and garlic. Season lightly with salt and cook until softened, about 6 minutes.
  • Simmer the Soup: Add roasted cauliflower to the pot along with the sage and broth. Bring to a simmer, then reduce heat and cook until everything is very soft, about 20 minutes. Remove the sage.
  • Blend Until Smooth: Transfer to a blender (in batches if needed) and blend until smooth and creamy. Alternatively, use an immersion blender.
  • Add Cream and Adjust: Return soup to the pot, stir in heavy cream, and thin with more broth or water until it reaches your preferred consistency. Season with salt and pepper.
  • Make the Curry Cream: Whisk together the heavy cream, sour cream, curry powder, and salt until soft peaks form.
  • Serve: Ladle hot soup into bowls and top with a generous spoonful of curry cream.

Notes

For dairy-free, use coconut cream and plant-based sour cream.

Use a high-speed blender for best texture.

Curry cream can be made up to 3 hours in advance.

Soup base stores well in the fridge for up to 5 days or in the freezer (without cream) for 3 months.
