01 - Heat the olive oil or butter in a large pot over medium heat. Add the chopped onion and sauté for 3–4 minutes until softened and translucent.
02 - Stir in the minced garlic, sliced carrots, and diced potato if using. Cook for 5 minutes, stirring occasionally, until the vegetables begin to soften.
03 - Add the ground cumin and ground ginger, stirring constantly for 1 minute until fragrant and evenly coating the vegetables.
04 - Pour in the vegetable broth and water. Bring to a boil, then reduce the heat to low, cover the pot, and simmer for 20–25 minutes until the carrots and potatoes are fork-tender.
05 - Remove the pot from heat. Use an immersion blender to purée the soup directly in the pot until silky smooth. Alternatively, carefully transfer the mixture to a stand blender in batches and blend until smooth.
06 - Stir in the heavy cream or coconut cream. Return to low heat if needed and warm through gently. Season with salt and freshly ground black pepper to taste.
07 - Ladle the soup into bowls and garnish with fresh parsley or chives. Serve immediately.
