Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x13-inch baking dish.

Combine buttermilk baking mix, pecans, paprika, salt, poultry seasoning, and sage in a shallow dish.

Dip chicken pieces in evaporated milk then coat generously with the pecan mixture. Place pieces in the prepared baking dish and drizzle with the melted butter.

Bake in the preheated oven until chicken is golden brown and an instant-read thermometer inserted near the bone reads 165 degrees F (74 degrees C), about 1 hour.
