Slow Cooker Green Bean Casserole with Crispy Onions

Thanks to fresh green beans, an easy homemade cream sauce and crispy onion topping, this green bean casserole recipe is healthier and more delicious than traditional recipes that use canned soup, beans and onions. Plus, the slow cooker saves you time cooking at the stove. Make sure to use fresh green beans, as frozen green beans will become mushy.
