In a large pot (big enough to add the creamy sausage and mushroom mixture to later) over high heat, bring chicken broth to a boil. Stir in wild rice, turn heat down to low/medium-low, cover, and simmer until wild rice is split open and curled. This should take around 45 minutes. Remove from heat and drain any excess liquid. Fluff with a fork and set aside.

Preheat oven to 325° F.

While wild rice is cooking, start frying the sausage. In a very large skillet with tall sides, over medium to medium-high heat, fry the sausage and onion together. Cook for 3 to 4 minutes, breaking up the sausage into bite-size pieces. Add garlic and mushrooms, stirring to combine. Cook until sausage is no longer pink and the onions and mushrooms have completely softened. Add butter, cream, and soy sauce. Add this mixture to the pot of cooked wild rice. Stir thoroughly to combine. Taste test, adding salt and pepper as needed. This dish should have plenty of flavor - don't be afraid to add salt, or even a bit more of the soy sauce. And I LOVE lots of black pepper!

Transfer to a large baking or casserole dish and bake for 30 minutes. Stir and bake for 20 minutes more. Stir and bake for 10 minutes. Sprinkle with parsley and serve hot.
