How Do You Make Green Bean Casserole with Fresh Green Beans?
To make green bean casserole with fresh green beans you simply need to trim the very ends off of the beans first, and then cut them in half. You can also purchase pre-trimmed green beans at your grocery store. Then, you will place them into a large pot of salted, boiling water for about 5 minutes, just until tender. If you like very soft green beans, you can boil them for a couple of extra minutes.
Can Green Bean Casserole be Made Ahead of Time?
Yes! If you’d like to make this casserole in advance, just make as directed and then allow it to cool completely to room temperature. Then, cover the casserole tightly with a layer of plastic wrap, and a layer of foil. Then, you can refrigerate for up to 48 hours. Or, you can freeze for up to 2 weeks.
How do you Make the Best Green Bean Casserole?
