Ingredients for Roasted Cauliflower Soup Recipe
- 1 large head cauliflower, cut into florets
- 2 tablespoons olive oil
- 1 medium yellow onion, chopped
- 3 garlic cloves, minced
- 4 cups low-sodium vegetable broth
- ½ cup heavy cream
- 1 medium potato, peeled and diced
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon smoked paprika
- ½ teaspoon dried thyme
- 1 tablespoon fresh lemon juice
- 2 tablespoons fresh parsley, chopped
- 2 tablespoons grated Parmesan cheese, optional
Instruction for Roasted Cauliflower Soup Recipe
1. Prepare the Cauliflower
Preheat your oven to 425°F. Place cauliflower florets on a lined baking sheet. Drizzle with olive oil, then add salt, pepper, and smoked paprika.
2. Roast the Cauliflower
Spread the cauliflower into one even layer. Roast for 25 to 30 minutes. Turn the florets halfway through cooking for even browning and better roasted flavor.
3. Cook the Aromatics
Heat a large pot over medium heat. Add a little olive oil, followed by chopped onion. Cook for five minutes until soft. Add garlic and thyme, then cook for another minute.
4. Add the Soup Ingredients
Add the roasted cauliflower to the pot. Add diced potato and vegetable broth. Stir everything together. Bring the mixture to a gentle boil, then reduce the heat.
5. Simmer Until Tender
Cover the pot loosely and simmer for about 12 to 15 minutes. The potato should become very tender. This helps everything blend into a smooth and creamy soup.
6. Blend the Soup
Turn off the heat and carefully blend the soup using an immersion blender. Blend until smooth and creamy. Work slowly to prevent hot soup from splashing.
7. Add the Cream
Stir in the heavy cream and lemon juice. Return the pot to low heat. Warm the soup gently for two to three minutes without boiling it.
8. Taste and Serve
Taste the soup and adjust the seasoning if needed. Ladle it into bowls while warm. Garnish with parsley and Parmesan cheese before serving.
