With just 4 ingredients, transform frozen green beans into a decadent slow cooker casserole

Green bean casserole is truly one of my favorite things in life. I love the tender green beans swimming in all of that sauce. And the crunchy onions on top are really just the salty, savory icing to it all. But when making it from scratch, it can be a bit of a pain. There are so many steps to take, and completing all those steps can take a really long time. Well, sweat over the stove no more. In the recipe below, you can let your slow cooker take over the hard lifting, so you're free to do....whatever you want.

Now, at the end of this recipe, you can just add the onions over the green beans and serve it straight from the slow cooker. But, I find that when done this way, the onions will fall into the green beans as you serve and have a chance of becoming soggy. That's why I either plate the casserole up first and then add the onions or, when I really don't want to do extra work, just serve them on the side at the table. But like any other kind of dish, you do you on this one.
