• 2 tablespoons olive oil
• ½ teaspoon salt
• ¼ teaspoon black pepper
• For the Soup Base
• 1 tablespoon olive oil or butter
• 1 medium onion, chopped
• 2 garlic cloves, minced
• 1 medium potato, peeled and diced (adds creaminess)
• 4 cups vegetable broth
• 1 cup plant-based milk or regular milk (unsweetened)

How to Make Roasted Cauliflower Soup

Step 1: Roast the Cauliflower

Preheat your oven to 220°C (425°F). Spread the cauliflower florets on a baking tray, drizzle with olive oil, and season with salt and pepper. Roast for 25–30 minutes, tossing once halfway, until golden and slightly charred at the edges.

Step 2: Sauté the Base Vegetables

While the cauliflower is roasting, heat 1 tablespoon olive oil or butter in a large soup pot. Add chopped onion and cook for 4–5 minutes until translucent. Stir in the garlic and diced potato and sauté for another 2 minutes.

Step 3: Add Broth and Simmer

Pour in the vegetable broth. Bring to a boil, then reduce heat to a simmer. Cook for 12–15 minutes, or until the potatoes are tender.

Step 4: Add Roasted Cauliflower

Once roasted, add the cauliflower (reserve a few florets for garnish if desired) to the pot. Stir and cook for 2–3 minutes more to allow flavors to meld.

Step 5: Blend the Soup

Remove the pot from heat. Using an immersion blender, purée the soup until silky smooth. Alternatively, let it cool slightly and blend in batches in a high-speed blender.

Step 6: Add Milk and Adjust Seasoning

Return the soup to low heat and stir in the milk. Heat gently without boiling. Taste and adjust salt, pepper, or even a pinch of nutmeg if you like.

Step 7: Serve

Ladle into bowls and garnish with roasted cauliflower florets, croutons, herbs, or a drizzle of olive oil.

Chef’s Notes

Roast for Depth: Roasting the cauliflower is key — don’t skip this step. It adds depth and sweetness that boiling alone cannot provide.

Creamy Without Cream: Potato helps add body to the soup naturally. You can skip milk altogether or use cashew cream for richness.

Make It Spicy: A sprinkle of red chili flakes or a swirl of sriracha adds a welcome kick.

Meal Prep Friendly: It freezes well in portions. Just thaw and reheat on the stovetop over low heat.
