Creamy Cauliflower and Aged Cheddar Soup

A velvety, rich cauliflower soup that gets its depth from slow-roasting the cauliflower first and finishing with sharp aged cheddar. Deceptively simple and incredibly flavorful.

Ingredients

  • 1 large head cauliflower (about 2.5 lbs), cut into florets
  • 1 large onion, diced
  • 4 cloves garlic, minced
  • 4 cups vegetable broth
  • 1 cup whole milk
  • 1.5 cups sharp aged cheddar, grated
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1/2 teaspoon dry mustard powder
  • 1/4 teaspoon white pepper
  • 1/4 teaspoon nutmeg
  • Salt to taste
  • Chives and extra cheddar for garnish

Instructions

  1. 1

    Preheat oven to 425°F. Toss half the cauliflower florets with olive oil and salt on a sheet pan. Roast for 25-30 minutes until deep golden and caramelized. This roasted portion adds a nutty, sweet depth.

  2. 2

    In a large pot, melt butter over medium heat. Sauté onion until very soft, about 8 minutes. Add garlic and cook 1 minute.

  3. 3

    Add the raw cauliflower (the other half) to the pot along with vegetable broth. Bring to a boil, then simmer for 15 minutes until tender.

  4. 4

    Add the roasted cauliflower to the pot. Using an immersion blender, blend until completely smooth. Add milk and blend again.

  5. 5

    Stir in mustard powder, white pepper, and nutmeg. Over low heat, add cheddar in two batches, stirring until fully melted. Do not boil after adding cheese.

  6. 6

    Season with salt. If too thick, add more broth or milk.

  7. 7

    Serve topped with a small mound of grated cheddar and a snip of fresh chives.
