Sauté the Veggies: Heat 2 tablespoon of butter or olive oil in a large stockpot over medium-high heat. Add the diced onion and sauté for 5 minutes, stirring occasionally, until soft and translucent. Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant, stirring occasionally.
Add Base Ingredients: Add the vegetable stock, wild rice, mushrooms, carrots, celery, sweet potato, bay leaf, and Old Bay seasoning to the pot. Stir gently to combine.
Simmer: Bring the soup to a simmer. Reduce the heat to medium-low, cover the pot, and let it simmer for 30 to 40 minutes. Stir occasionally and cook until the rice is tender.
Add Final Ingredients: Pour in the coconut milk and add the kale. Stir gently to combine. Taste the soup and season with fine sea salt and freshly cracked black pepper. Adjust with more Old Bay seasoning if desired.
Serve:Ladle the soup into bowls, serve warm, and enjoy!
