Rinse the wild rice and cook in a separate pot according to package directions until tender, then drain and set aside.
In a large heavy-bottomed Dutch oven, melt the butter over medium heat.
Add the onion, celery, and bell pepper to the pot and sauté until softened, approximately 6 to 8 minutes.
Add the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the vegetables and stir constantly for 3 minutes to create a blonde roux.
Slowly whisk in the seafood stock, ensuring no lumps form from the flour.
Bring the liquid to a gentle simmer and stir in the cooked wild rice and Creole seasoning.
Reduce the heat to low and stir in the heavy cream and Worcestershire sauce.
Gently fold in the lump crab meat, being careful not to over-break the large pieces.
Heat the stew through for 5 to 7 minutes without allowing it to reach a hard boil.
Season with salt, black pepper, and hot sauce to preference.
Garnish with fresh parsley and sliced green onions before serving.
