Green bean casserole, a classic American dish made from green beans, cream of mushroom soup, and french-fried onions, is a staple at many family gatherings and holidays. Its creamy, savory flavor and crunchy texture make it a crowd-pleaser. However, like any food, it has a limited shelf life, and understanding how to store it properly is crucial for maintaining its quality and ensuring food safety. In this article, we will delve into the details of how long green bean casserole keeps, the factors that affect its shelf life, and provide tips on how to store it to maximize its freshness.
Introduction to Green Bean Casserole and Its Storage Needs
Green bean casserole is a perishable item due to its high moisture content and the presence of dairy products, which can support the growth of bacteria and mold. The casserole typically consists of cooked green beans, canned cream of mushroom soup, milk, french-fried onions, and sometimes ground black pepper and salt.
