Ingredients

Main Ingredients

  • 1 large head cauliflower, cut into florets (about 4-5 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 sub chicken broth if not vegetarian)
  • ½ 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 serving

Instructions

  1. Preheat the Oven: Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper to prepare for roasting.
  2. Roast Cauliflower and Garlic: Toss the cauliflower florets with 1-2 tablespoons of olive oil, salt, and pepper, then spread them on the baking sheet. Prepare the garlic by peeling off outer papery layers but leaving individual clove skins intact; cut ¼ inch off the top to expose cloves, drizzle with olive oil, wrap loosely in foil, and place on the sheet. Roast cauliflower and garlic for 30-35 minutes, flipping cauliflower halfway through, until golden and caramelized.
  3. Sauté 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 fragrant.
  4. Blend the Soup: Allow the roasted garlic to cool enough to handle, then squeeze out the softened cloves. In a large blender, combine the sautéed onion, roasted cauliflower, roasted garlic, vegetable broth, salt, and pepper. Blend until completely smooth, about 1 minute. Pour the blended mixture back into the pot over medium heat.
  5. Simmer and Add Cheese: Bring the soup to a gentle simmer and stir in the shredded sharp cheddar cheese. Continue simmering for 10-15 minutes until the cheese melts fully and the soup thickens slightly. Taste and adjust seasoning with additional salt and pepper as needed.
  6. Serve and Garnish: Ladle the soup into bowls and garnish with sliced green onions and extra shredded cheddar cheese. Serve alongside croutons or toasted sourdough for dipping.

Notes

  • For a creamier texture, substitute 1 cup of broth with 1 cup of milk, or replace ½ cup of broth with ½ cup half and half or heavy cream for a richer flavor.
  • If you prefer a thicker soup, reduce the broth amount to 3 cups instead of 4 cups.
  • Adjust the seasoning at the end of cooking to balance salt and pepper to taste.
  • Serve with crusty bread or croutons to add texture and extra comfort.
  • This soup is naturally gluten-free and vegetarian, but can be made non-vegetarian by using chicken broth instead of vegetable broth.
