If Frozen, thaw hen in the refrigerator for at least a day.
Season hens inside and out with seasoning mix, then stuff with equal amounts butter, veggies, and herbs . Place stuffed birds in a 9x13 inch baking dish, breast side up. Drizzle with 1/4 cup melted butter.
Pop it in the oven and bake for 1 hour or more until nicely browned. Make sure to baste cornish hen with drippings throughout the baking process
