Creamy Roasted Cauliflower Soup Recipe
Introduction
This creamy roasted cauliflower soup is a comforting and flavorful dish perfect for any season. Roasting the cauliflower brings out a rich, nutty sweetness that blends beautifully with sautéed aromatics and a touch of cream for a silky finish.

Ingredients
- 1 large head of cauliflower (cut into florets)
- 2 tablespoons olive oil
- 1 medium onion (chopped)
- 2 cloves garlic (minced)
- 4 cups vegetable broth (or chicken broth)
- 1 cup heavy cream (or coconut milk for a dairy-free option)
- Salt and pepper (to taste)
- 1 teaspoon smoked paprika (optional)
- Fresh chives or parsley (for garnish)
Instructions
- Step 1: Preheat your oven to 425°F (220°C). Toss the cauliflower florets with olive oil, salt, and pepper on a baking sheet, spreading them in a single layer. Roast for 25-30 minutes until golden brown and tender, stirring halfway through.
- Step 2: In a large pot, heat a little olive oil over medium heat. Add the chopped onion and sauté for about 5 minutes until softened. Add the minced garlic and cook for an additional 1-2 minutes until fragrant.
- Step 3: Add the roasted cauliflower to the pot with the onion and garlic. Pour in the vegetable broth and bring to a simmer. Let it simmer for 10 minutes to meld the flavors.
- Step 4: Blend the soup until smooth using an immersion blender or transfer in batches to a countertop blender. Return the soup to the pot if needed, stir in the heavy cream or coconut milk, and heat through without boiling.
- Step 5: Taste and adjust seasoning with salt, pepper, and smoked paprika if using. Serve hot, garnished with fresh chives or parsley.
Tips & Variations
- For a dairy-free version, substitute heavy cream with full-fat coconut milk for a rich, creamy texture.
- Adding smoked paprika enhances depth, but you can omit it for a milder flavor.
- Use homemade or low-sodium broth to control the saltiness of the soup.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat to prevent curdling. This soup can also be frozen for up to 2 months; thaw in the fridge overnight before reheating.

- 1 medium onion (chopped)
- 2 cloves garlic (minced)
- 4 cups vegetable broth (or chicken broth)
Dairy
- 1 cup heavy cream (or coconut milk for a dairy-free option)
Garnish
- Fresh chives or parsley (for garnish)
Instructions
- Preheat and roast cauliflower: Preheat your oven to 425°F (220°C). On a baking sheet, toss the cauliflower florets with olive oil, salt, and pepper, spreading them in a single layer. Roast for 25-30 minutes until golden brown and tender, stirring once halfway through.

Notes

- Smoked paprika adds a subtle smoky flavor but can be omitted if preferred.
