Begin by heating a large pot over medium heat. Add chopped onion and minced garlic to the pot, sautéing them for about 5 minutes until they become fragrant and translucent.

Next, introduce cubed purple sweet potatoes to the pot, stirring them to coat with the aromatic mixture. Sauté for an additional 5 minutes.

Pour in the vegetable broth, ensuring you cover the sweet potatoes well, and bring the mixture to a gentle boil.

Once boiling, stir in the shredded red cabbage carefully. Allow the soup to simmer for 15 minutes.

Reduce the heat to low and mix in the creamy coconut milk, along with fresh thyme, salt, and pepper. Stir to combine.

Taste your Mystical Witch Soup and adjust the seasoning as needed.

Ladle the soup into bowls, garnishing each with a sprinkle of black sesame seeds for a touch of elegance.
