Instructions
Preheat the Oven
Preheat the oven to 425°F (220°C). If desired, line a large sheet pan with parchment paper to facilitate easier cleanup.
Roast the Vegetables
Place the cauliflower florets, sliced onion or leek, and optional garlic cloves directly on the prepared sheet pan. Drizzle the vegetables with 3 tablespoons of olive oil and toss until evenly coated.
Spread the vegetables into a single layer to ensure proper roasting. Roast in the preheated oven for approximately 30 minutes, or until the cauliflower florets develop well-browned edges and the vegetables are tender.
Combine with the Stock
Transfer the roasted vegetables to a large saucepan. If garlic cloves were roasted, remove and discard the skins before adding the softened garlic to the pot.
Pour the vegetable stock into the saucepan and bring the mixture to a rolling boil over high heat. Once boiling, immediately turn off the heat.
Purée the Soup
Using an immersion blender, purée the soup directly in the pot until the mixture becomes smooth and creamy.
Alternatively, transfer the soup in batches to a countertop blender and blend carefully until smooth.
Taste the soup and season with salt as needed.
Finish and Serve
In a small bowl, combine the remaining 2 tablespoons olive oil with the smoked paprika, stirring until well blended.
Ladle the hot Roasted Cauliflower Soup into serving bowls and drizzle the paprika oil over the surface of the soup before serving.
Serve immediately while hot.
