Step‑by‑Step Instructions for Creamy Roasted Cauliflower and Asiago Soup
Step 1: Prepare Garnishes
Preheat your oven to 400°F (200°C) for Parmesan tuiles. On a baking sheet lined with parchment paper, arrange small mounds of grated Parmesan cheese, spacing them apart. Additionally, lay prosciutto slices on another sheet to bake until crispy, about 10-15 minutes. Once done, set both garnishes aside while you prepare the soup.
Step 2: Roast Cauliflower
Now, lower the oven temperature to 375°F (190°C) for roasting the cauliflower. Toss the fresh cauliflower florets in a generous drizzle of extra virgin olive oil and sprinkle with kosher salt. Spread them out on a baking sheet and roast for 40 minutes, until they’re tender and beautifully caramelized, turning them halfway through for even roasting.
Step 3: Sauté Onions
In a large pot over medium heat, melt unsalted butter. Add diced onions and sauté them for about 5-7 minutes, stirring frequently, until they turn translucent. Near the end of this process, introduce black pepper and dried thyme, allowing their fragrant aromas to permeate the kitchen as you continue sautéing for an additional minute.
Step 4: Cook Soup Base
Once your onions are ready, combine the roasted cauliflower, sautéed onions, vegetable stock, minced garlic, and ground coriander in the pot. Bring this mixture to a gentle boil over medium-high heat. After it reaches a boil, reduce the heat and let it simmer uncovered for 20 minutes, allowing the flavors to meld beautifully.
Step 5: Blend Soup
Using a high-powered blender or an immersion blender, carefully blend the soup until it reaches a velvety smooth consistency. If using a traditional blender, wait for the soup to cool slightly before blending in batches for safety. Return the blended soup to the pot, and stir in heavy cream and grated asiago cheese, heating gently over low until the cheese melts.
Step 6: Finalize and Serve
Taste and adjust seasoning, adding more salt or pepper if needed. Ladle the creamy roasted cauliflower and asiago soup into warm bowls and garnish with crispy prosciutto, Parmesan tuiles, and fresh thyme leaves for added flair. Serve immediately and enjoy the comforting richness on those chilly evenings.

Creamy Roasted Cauliflower and Asiago Soup Recipe FAQs
What type of cauliflower should I use?
