- Preheat your oven to 350°F (175°C). Slice off the top of the whole head of garlic and drizzle with olive oil. Wrap in foil and roast for about 30 minutes until soft.
- Clean the leeks by discarding the dark green tops and rinse thoroughly. Peel and dice the sweet potato into 1/2-inch chunks.
- In a large pot, heat olive oil over medium heat. Add leeks and sauté for about 8-10 minutes until soft and translucent.
- Stir in curry powder, chili powder, turmeric, and cardamom. Cook for 2-3 minutes to bloom the spices.

- Squeeze the roasted garlic cloves into the soup and blend until smooth with an immersion blender.
