Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the chicken breast, wild rice, chicken broth, mushrooms, broccoli, and condensed cream of mushroom soup.
Season with salt and black pepper, then stir all ingredients until well combined.
Transfer the mixture to a baking dish and spread it evenly.
Cover the baking dish with aluminum foil and bake for 60 minutes in the preheated oven.
Remove the foil and bake for an additional 10-15 minutes, or until the rice is cooked and the chicken is tender.
Let it cool for a few minutes before serving.
