Roasted Cauliflower Soup
Description
Roasted Cauliflower Soup starts with oven roasting diced cauliflower tossed in olive oil until browned, which imparts a mild caramelized flavor and tender texture. Separately, bacon is cooked until crisp and set aside, then onions are sautéed in the residual bacon fat, enhancing the soup's savory base. The roasted cauliflower, chicken broth, fresh thyme, salt, pepper, and nutmeg are combined and cooked together to marry flavors, then cooled slightly before puréeing until smooth. The soup is returned to the pot, then finished with whole milk, heavy cream, and freshly grated Parmesan cheese, creating a creamy consistency with a subtle cheesy richness.
The flavor balance arises from the roasted cauliflower’s mild sweetness and earthiness, contrasted by the smoky saltiness of bacon and the aromatic fresh thyme. The texture after blending is smooth and velvety, suitable as a starter or light main dish. The recipe allows for vegetarian adaptations by substituting vegetable broth for chicken broth and using vegan bacon alternatives, though additional olive oil is suggested to compensate for the loss of bacon fat flavor. Parmesan contributes little lactose, making it accessible to some lactose intolerant individuals.
Serving suggestions include garnishing with crisp bacon bits, thyme sprigs, and extra Parmesan to add texture and layered flavors. The soup can be prepared a day ahead and refrigerated, and leftovers can be frozen for up to three months. When reheating, warm over low heat to preserve texture and prevent curdling. This recipe offers a satisfying way to enjoy cauliflower with both richness and freshness from herbs.
