Preheat your oven to 350°F (175°C).
Cook the wild rice according to package instructions.
In a large mixing bowl, combine cream of mushroom soup, cream of chicken soup, milk, and black pepper. Mix until smooth.
Add the cooked wild rice, shredded chicken, celery, onion, carrots, and half of the cheese to the bowl. Mix well.
Pour the mixture into a greased 9x13-inch baking dish. Spread evenly.
Top with the remaining cheese and sliced almonds, if using.
Bake for 25-30 minutes, or until bubbly and golden on top.
Let the casserole cool for 5 minutes before serving.
