Ingredients

  • 1 large head cauliflower, cut into florets (about 4-5 cups)
  • 3 tablespoons olive oil, divided
  • Freshly ground salt and pepper
  • 1 head garlic
  • 1 medium yellow onion, diced
  • 4 cups vegetable broth (or chicken broth if not vegetarian)
  • ½ teaspoon salt, plus more to taste
  • Freshly ground black pepper
  • 1 heaping cup shredded sharp cheddar cheese
  • To garnish: sliced green onion and extra cheddar cheese
  • Croutons or toasted sourdough bread for serving

Instructions

  1. Step 1: Preheat the oven to 400 degrees F and line a baking sheet with parchment paper. Place cauliflower florets on the sheet, drizzle with 1-2 tablespoons olive oil, season generously with salt and pepper, and toss to coat.
  2. Step 2: Prepare the garlic by peeling off the outer papery layers of the whole head, leaving the skins on individual cloves. Cut ¼ inch off the top to expose the cloves. Drizzle with olive oil, wrap loosely in foil, and place on the baking sheet with the cauliflower.
  3. Step 3: Roast cauliflower and garlic in the oven for 30-35 minutes, flipping halfway through, until golden and caramelized.
  4. Step 4: While roasting, heat 1 tablespoon olive oil in a pot over medium heat. Add diced onion and sauté for 5-8 minutes until translucent.
  5. Step 5: Once roasted, let the garlic cool enough to handle and squeeze the soft roasted garlic out of the skins.
  6. Step 6: In a blender, combine the sautéed onion, roasted cauliflower, roasted garlic, broth, ½ teaspoon salt, and pepper. Blend until smooth, about 1 minute.
  7. Step 7: Pour the blended soup back into the pot and heat over medium until it reaches a light simmer.
  8. Step 8: Stir in the shredded cheddar cheese and simmer for 10-15 minutes, adjusting seasoning as needed.
  9. Step 9: Serve garnished with sliced green onion and extra cheddar. Enjoy with croutons or toasted sourdough bread.

Tips & Variations

  • For a creamier texture, add a splash of heavy cream or milk before serving.
  • Try swapping sharp cheddar for smoked gouda or fontina for a different cheese flavor.
  • Roast the cauliflower and garlic together for deeper, combined flavors but be careful not to burn the garlic.
  • Use homemade broth for an extra depth of flavor.

Storage

Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring occasionally. If the soup thickens too much upon cooling, add a splash of broth or water to loosen it when reheating.

How to Serve

The image shows three white cups filled with a creamy beige soup, each sprinkled with slices of green onions and a little black pepper on top. The soup looks thick and smooth with a bit of melted cheese visible in one cup. A woman's hand is dipping a piece of golden-brown crusty bread into the soup, and the bread is covered with gooey melted cheese stretching from the cup. The cups sit on a white marbled surface with some small green onion slices scattered around. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

Scale

Vegetables

  • 1 large head cauliflower, cut into florets (about 45 cups)
  • 1 head garlic
  • 1 medium yellow onion, diced

Liquids and Broth

  • 4 cups vegetable broth (or chicken broth if not vegetarian)

Oils and Seasonings

  • 3 tablespoons olive oil, divided
  • ½ teaspoon salt, plus more to taste
  • Freshly ground salt and pepper to taste
  • Freshly ground black pepper to taste

Dairy

  • 1 heaping cup shredded sharp cheddar cheese

Garnishes and Serving

  • Sliced green onion
  • Extra shredded sharp cheddar cheese for topping
  • Croutons or toasted sourdough bread for dipping/serving

Instructions

  1. Prepare for Roasting: Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper. This ensures even cooking and easy cleanup.
  2. Roast Cauliflower and Garlic: Place cauliflower florets on the lined baking sheet. Drizzle with 1-2 tablespoons olive oil, season generously with salt and pepper, and toss to combine. Prepare the garlic by peeling off the outer papery layers, leaving individual clove skins intact, then slice ¼ inch off the tops to expose the cloves. Drizzle olive oil on the garlic head, wrap it loosely in foil, and place it alongside the cauliflower. Roast both for 30-35 minutes, flipping the cauliflower halfway through, until golden and caramelized.
  3. Sauté Onion: While the cauliflower roasts, heat 1 tablespoon olive oil in a pot over medium heat. Add the diced onion and sauté for 5-8 minutes until translucent and fragrant.
  4. Blend Soup Ingredients: Once the cauliflower and garlic are done roasting, allow the garlic to cool enough to handle. Squeeze out the softened roasted garlic cloves from their skins. In a large blender, combine the sautéed onion, roasted cauliflower, roasted garlic, vegetable broth, salt, and pepper. Blend until smooth, about 1 minute, then pour the mixture back into the pot.
  5. Simmer and Add Cheese: Heat the blended soup over medium heat until it reaches a light simmer. Stir in the shredded sharp cheddar cheese and continue to simmer gently for 10-15 minutes. Taste and adjust seasonings as needed.
  6. Garnish and Serve: Ladle the soup into bowls, garnish with sliced green onions and extra shredded cheddar cheese. Serve warm accompanied by crusty toasted sourdough bread or croutons for dipping.

Notes

  • You can substitute chicken broth for vegetable broth if not following a vegetarian diet.
  • Toasting the bread enhances the dipping experience and adds texture contrast.
  • For a smoother texture, strain the soup through a fine mesh sieve if desired after blending.
  • Use sharp cheddar for best flavor impact, but mild or medium cheddar can be substituted.
  • Leftovers keep well refrigerated for up to 3 days and reheat gently on the stovetop or microwave.
