Description

A creamy and savory roasted cauliflower soup with sharp cheddar cheese and roasted garlic, perfect for cozy days. Serve it with crusty bread for dipping, and garnish with sliced green onions and extra cheddar.


Ingredients

Units Scale
  • 1 large head cauliflower, cut into florets (about 45 cups cauliflower florets)
  • 3 tablespoons olive oil, divided
  • Freshly ground salt and pepper, to taste
  • 1 head garlic
  • 1 medium yellow onion, diced
  • 4 cups vegetable broth (or substitute chicken broth if not vegetarian)*
  • 1/2 teaspoon salt, plus more to taste
  • Freshly ground black pepper, to taste
  • 1 heaping cup shredded sharp cheddar cheese

To garnish:

  • Sliced green onion & extra cheddar on top
  • Croutons or toasted sourdough bread for dipping/serving

Instructions

  1. Preheat the Oven:
    Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
  2. Roast the Vegetables:
    Place the cauliflower florets on the prepared baking sheet. Drizzle with 1-2 tablespoons of olive oil, season with salt and pepper, and toss to coat evenly.
    For the garlic, peel away the outer papery layers, leaving the skins of the individual cloves intact. Cut ¼ inch off the top of the garlic head, exposing the tops of the cloves. Place the garlic on a sheet of foil, drizzle with olive oil, and loosely wrap the foil around it. Place the foil-wrapped garlic on the baking sheet with the cauliflower.
    Roast for 30-35 minutes, flipping the cauliflower halfway through, until the cauliflower is golden brown and caramelized.
  3. Cook the Onion:
    While the cauliflower and garlic are roasting, heat 1 tablespoon of olive oil in a pot over medium heat. Add the diced onion and sauté for 5-8 minutes until the onion becomes translucent.
  4. Blend the Soup:
    Once the cauliflower and garlic are done roasting, add the sautéed onion, roasted cauliflower, roasted garlic (squeezed from the skins), broth, salt, and pepper to a blender. Blend until smooth, about 1 minute. Pour the blended soup back into the pot and place over medium heat.
  5. Finish the Soup:
    Bring the soup to a light simmer, then stir in the shredded cheddar cheese. Continue to simmer for 10-15 minutes, stirring occasionally. Taste and adjust seasonings as needed.
  6. Serve:
    Garnish the soup with sliced green onions and extra cheddar cheese. Serve with crusty toasted sourdough bread or your favorite bread for dipping.

Notes

  • For a creamier soup, you can substitute 1 cup of broth with 1 cup of milk.
  • For a richer texture, add ½ cup of half-and-half or heavy cream in place of ½ cup of broth.
  • If you prefer a thicker soup, reduce the amount of broth to 3 cups.
  • Customize the soup with additional spices or herbs based on your preference.
