Holiday times are simultaneously my favorite and my least favorite time of the year. I love challenging myself for new nontraditional side dishes like cast iron spinach and also lean heavily on old family favorites like Watergate Salad and Ambrosia salad. I think one of the biggest issues for me when it comes to baking and cooking is limited space. This is why crock pots and slow cookers are so important to the holiday eating season.

Once the turkey is in, the oven seems to be filled for a good part of the day, so I always line my counter with slow cookers and my stove with skillets and do what I can.

Because green bean casserole CANNOT be skipped at Thanksgiving time, this is a simple and easy slow cooker green bean casserole that should help if your oven is already full. This recipe will taste like your old favorite but can be put on early in the morning and done when your other sides are done. Plus, slow cookers keep food warm and everyone loves that. 

If you are wanting to skip the soup and do a really truly homemade green bean casserole, you cannot go wrong with this recipe instead: From Scratch Green Beans (without canned soup) – Its my very favorite way to make green beans.
