Make green bean casserole with canned, frozen (thawed), or fresh green beans. If using fresh green beans, they work best when blanched beforehand so they fully cook in the oven along with the creamy mushroom sauce. You can prepare this casserole ahead of time by covering it tightly and freezing it until ready to serve.
