Heat the olive oil in a large pot over medium heat. Once shimmering, add the diced onion. Sauté for about 5 minutes until the onion becomes translucent and soft.

Add the minced garlic and ginger to the pot. Stir constantly for about 1 minute until fragrant. Be careful not to burn the garlic.

Toss in the chopped carrots and cumin. Stir everything together, coating the carrots with the aromatic mixture. Cook for another 2-3 minutes.

Pour in the vegetable broth. Add the salt and black pepper. Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for 20-25 minutes until the carrots are completely tender when pierced with a fork.

Remove the pot from the heat. Using an immersion blender, blend the soup until completely smooth and creamy. Alternatively, transfer the soup in batches to a regular blender.

Stir in the fresh lime juice. Taste and adjust the seasoning if needed.

Ladle the soup into bowls. Serve hot with your favorite garnishes and enjoy immediately.
