Rinse the wild rice under cold water until the water runs clear, removing any debris or dust. In a large pot, bring 6 cups chicken broth to a boil, then add rinsed wild rice and reduce heat to low. Simmer covered for 40-45 minutes until grains are tender but still have a slight bite.
While rice cooks, melt butter in a large skillet over medium heat. Sauté diced onion and celery for 5-7 minutes until softened and fragrant, stirring occasionally to ensure even cooking without browning.
Add sliced mushrooms to the vegetable mixture and cook for another 4-5 minutes until they release their moisture and begin to golden. The mushroom liquid creates the foundation for deep, savory flavor in this wild rice stuffing crowd favorite.
In a large mixing bowl, combine the cooked wild rice, sautéed vegetables, chopped turkey strips, dried cranberries, pecans, bread cubes, thyme, sage, salt, and pepper. Pour beaten eggs over the mixture and fold gently until ingredients distribute evenly throughout, being careful not to crush the wild rice grains.
Transfer the mixture to a buttered 9x13-inch baking dish, spreading evenly. Bake at 350°F for 45-50 minutes until the top becomes golden brown.
About 15 minutes before the end of baking, brush the top with the reserved 1/2 cup chicken broth using a pastry brush. This step ensures the stuffing stays moist and develops a beautiful golden crust without drying out.
Let the baked dish rest for 5 minutes before serving, allowing the structure to set slightly for cleaner portions.
