Sautee most of the vegetables: Get out a large pot and melt the tablespoon of butter in it over medium-high heat. Then toss in the onion, carrot, and celery, and sautee these ingredients for 5 minutes or until the onions are translucent. Finally toss in the garlic, sage, oregano, and thyme and continue sauteing for another minute.
Add the chicken stock, wild rice, mushrooms, and bay leaf to the pot.
Cook the soup: Stir all of these ingredients together and let it come to a boil. Then reduce the heat to a simmer, cover the pot with a lid, and let the soup cook for about 1 hour or until the rice is tender.
Finnish the soup: Pour in the ¼ cup of cream to the soup and stir everything together. If the soup isn’t as thick and creamy as you’d like then you can add in an additional ¼ cup of cream. The amount of cream is completely up to you and your personal preference. Finally, add salt and pepper to taste, it will probably need a good amount of salt.
Serve the wild rice soup immediately and garnish it with some freshly minced parsley.
