Ingredients for Roasted Cauliflower Soup

To create this creamy roasted cauliflower soup, gather the following ingredients:

  • Cauliflower: Use the entire head, including the stem and florets.
  • Potatoes: For a creamy texture without the need for cream.
  • Leek and Onion: To infuse a gentle sweetness into the soup.
  • Garlic: The recipe calls for five cloves, but you can add more for extra garlic flavor.
  • Broth: I’ve used chicken broth, but vegetable broth is a fine alternative.
  • Milk: To provide creaminess and a touch of protein.
  • Mustard: Adding depth of flavor and a hint of spice.
  • Nutmeg: To introduce warmth and fragrance.
  • Cheese: Enhancing creaminess and flavor, either parmesan or cheddar works well.

In addition, you’ll need butter, olive oil, salt, and black pepper. Optional toppings include parsley and red pepper flakes.

Dietary Adaptions

To accommodate various dietary preferences, here are some adaptations:

Make it Gluten-Free: No adjustments are necessary; this recipe is naturally gluten-free. Just verify the label of store-bought chicken broth for gluten content.

Make it Dairy-Free: Replace butter with additional olive oil, substitute milk with unsweetened non-dairy milk like coconut milk, and omit parmesan cheese.
