Ingredients

Scale

Soup Ingredients

  • 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 shredded cheddar cheese
  • 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 to prepare for roasting the vegetables.
  2. Roast the Vegetables: Place cauliflower florets on the baking sheet, drizzle with 1-2 tablespoons olive oil, and season with salt and pepper. Toss to coat evenly. Prepare the garlic by peeling outer layers, keeping individual clove skins, then cut ¼ inch off the top to expose cloves. Drizzle garlic with olive oil, wrap with foil and place on the baking sheet with cauliflower. Roast for 30-35 minutes, flipping the cauliflower halfway through, until golden brown and caramelized.
  3. Cook the Onion: While roasting, heat 1 tablespoon olive oil in a pot over medium heat. Add diced onion and sauté for 5-8 minutes until translucent and soft.
  4. Blend the Soup: Once roasting is complete, squeeze the roasted garlic cloves out of their skins. In a blender, combine the roasted cauliflower, garlic cloves, sautéed onion, broth, salt, and pepper. Blend until smooth, approximately 1 minute. Pour the blended mixture back into the pot and heat over medium heat.
  5. Finish the Soup: Bring soup to a light simmer and stir in the shredded cheddar cheese. Continue simmering for 10-15 minutes, stirring occasionally until cheese is melted and soup thickens slightly. Adjust seasoning to taste.
  6. Serve: Ladle soup into bowls and garnish with sliced green onions and extra cheddar cheese. Serve with croutons or toasted sourdough bread on the side for dipping.

Notes

  • For a creamier soup, substitute 1 cup of broth with 1 cup of milk.
  • For a richer texture, add ½ cup of half-and-half or heavy cream instead of ½ cup broth.
  • To make the soup thicker, reduce broth to 3 cups.
  • Customize the soup by adding your favorite herbs or spices like thyme, paprika, or cayenne for extra flavor.
