Pour everything into a 9x13 casserole dish, scraping the sides well to get all the casserole ingredients out.
Using a large spoon or spatula, press casserole into dish so everything is tightly packed.
Cover securely with foil (first lengthwise, then widthwise) and bake on the center oven rack at 350 degrees for 60 - 70 minutes until the internal temperature of the casserole is at least 165 degrees Fahrenheit.
(Optional/not pictured) - mix together breadcrumbs and melted butter. Remove foil and sprinkle mixture over casserole. Broil 2 - 3 minutes until bread crumbs are browned (make sure you're using a broiler safe dish and watch closely!).
Allow to rest about 5 - 10 minutes before serving.
