Ingredients
For the Soup
- 1 large head of cauliflower (about 2 pounds, trimmed and chopped)
- 1 tablespoon olive oil
- 1 medium onion (chopped)
- 3 cloves garlic (minced)
- 4 cups vegetable broth (or chicken broth)
- 1 teaspoon ground cumin
- 1 teaspoon salt (to taste)
- 1/2 teaspoon black pepper
- 1/2 cup coconut milk (or heavy cream)
For the Garnish (optional)
- 1 tablespoon fresh parsley (chopped)
- 1/4 cup toasted pumpkin seeds
- 1 tablespoon lemon juice
Equipment Needed
- Large baking sheet (for roasting cauliflower)
- High-speed blender or immersion blender (for smooth soup texture)
- Medium saucepan (for simmering broth)
- Cutting board (for chopping vegetables)
- Chef’s knife (for cutting cauliflower and aromatics)
- Measuring cups and spoons (for precise ingredient measurement)
- Wooden spoon (for stirring soup)
- Fine mesh strainer (optional, for extra smooth consistency)
How to Make Roasted Cauliflower Soup
Prepare the Cauliflower
- Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.
- Cut the cauliflower. Remove the leaves and stem, then break the cauliflower into florets, about 1-2 inches in size.
- Toss florets with oil. In a large bowl, combine the cauliflower florets with 2 tablespoons of olive oil, salt, and pepper until evenly coated.
- Roast the cauliflower. Spread the florets in a single layer on the prepared baking sheet and roast for 25-30 minutes, or until golden brown and tender, stirring halfway through for even cooking.
Prepare the Soup Base
- Cook the aromatics. In a large pot, heat 2 tablespoons of olive oil over medium heat. Add diced onion and minced garlic, cooking for about 5 minutes until the onion is translucent and fragrant.
- Add the broth. Pour in 4 cups (950 ml) of vegetable broth and bring the mixture to a simmer.
- Add roasted cauliflower. Once the broth is simmering, add the roasted cauliflower to the pot. Allow it to simmer for an additional 5 minutes to meld the flavors.
Blend and Serve
- Blend the soup. Using an immersion blender, puree the soup until smooth. If you don’t have one, transfer batches to a countertop blender, but be careful with the hot liquid.
- Adjust seasoning. Taste the soup and add more salt and pepper if needed. For a creamier texture, stir in 1/2 cup (120 ml) of heavy cream or coconut milk.
- Serve hot. Ladle the soup into bowls and garnish with a drizzle of olive oil or a sprinkle of fresh herbs, if desired.
Tips for the Best Roasted Cauliflower Soup
- Choose fresh cauliflower — Look for firm, compact heads with no brown spots for the best flavor and texture.
- Don’t rush the roasting — Roast your cauliflower until it’s golden and slightly caramelized; this adds depth to the soup’s flavor.
- Use vegetable stock — Consider swapping out water for vegetable stock instead. It enhances the soup’s richness without adding calories.
- Add creaminess with cashews — For a vegan option, blend soaked cashews into the soup for a creamy texture instead of heavy cream.
- Spice it up — For a spicy version, add red pepper flakes or a dash of cayenne during cooking to elevate the heat level.
- Make it ahead — This soup stores well in the fridge for up to three days; just reheat gently, adding a splash of water to thin if necessary.
Variations to Try
- Herb-infused version — Stir in fresh herbs like thyme or rosemary towards the end of cooking for an aromatic twist.
- Curried cauliflower soup — Add 1-2 tablespoons of curry powder while sautéing the onions to introduce warm, exotic flavors.
- Cheesy upgrade — Mix in grated Parmesan during blending for a savory, cheesy note that complements the cauliflower.
- Roasted garlic addition — Roast a bulb of garlic along with the cauliflower and blend it into the soup for a mellow, sweet garlic flavor.
