Easy green bean casserole is a Thanksgiving tradition and a huge family favorite. Making green bean casserole is simple with this one-pot recipe. It’s easy being green and damn delicious.

What Is In Green Bean Casserole

According to Wikipedia “Green bean casserole is a casserole consisting of green beans, cream of mushroom soup, and french fried onions. It is a popular Thanksgiving side dish in the United States, created in 1955 by Campbell’s”. However, that seems really boring. Green bean casserole can be so much more than that. Those ingredients, for one thing, are boring as hell. Why not add some mushrooms, onions, cheese, bacon or other pre-cooked meat. Green bean casserole doesn’t have to be boring. See the bottom of this post for some ingredient ideas on how to spruce up your casserole.

Some of the ingredients in green bean casserole.

Green Bean Casserole Frozen, Canned, Or Fresh

Mom always made green bean casserole with frozen or canned green beans. Considering this vegetable is going into a casserole, this does save a lot of time. Especially when you are preparing a ton of dishes for a holiday meal. While canned and frozen are easy, fresh is best. To prepare the green beans, wash them and then clip off the ends. If the green beans are long, you can cut them into a more uniform size. Saute the green beans for about 3 to 5 minutes before adding to the casserole. If you are adding fresh mushrooms, saute those with the green beans.

Green Bean Casserole Make Ahead Tips

If making ahead for a holiday you can prepare the casserole ahead of time and store it in the refrigerator for up to 3 days. While the oven is heating up you can add the french fried onions. You can do the same if making ahead to take on a campout. Prep the casserole in a Dutch oven liner, over tightly keep in the color until ready to bake. While the coals are preparing, place the liner in a Dutch oven and add the french fried onions. Bake at the same temperature and time you would as in an oven. Consult the Dutch oven coal chart for more information on how many coals you will need to attain the correct temperature.

How Long Is Green Bean Casserole Good For

A general rule of thumb for leftovers without meat is three to five days. If you add meat like bacon it should be fine for that long as well. Bacon is processed. Something like fresh chicken should probably only be kept for up to three days. Do not, I repeat, do not freeze green bean casserole, the beans will not hold out well and it will lose any crispiness from the onions.

How To Make Green Bean Casserole Over A Campfire

I recommend using a Dutch oven to make green bean casserole over a campfire. Refer to the Dutch oven coal chart on this website to find out how many coals to use. I love cooking casseroles over a campfire because it means using a Dutch oven which is a lot of fun. No room in your oven this holiday? Why not cook the green bean casserole in a cast iron dish out on the grill or over a campfire. A good outdoor Dutch oven will make it easy and fun and keep your hubby busy so he’s not messing with your turkey.

Green Bean Casserole Recipes

It is easy to turn campfire green bean casserole into a meal by adding some meat to the dish. Ham, Italian sausage or hamburger all work really well in this dish. Just be sure that the meat is cooked before you add it to the casserole. I like a lot of cheese with my casseroles, so I often increase the amount of cheese listed in the recipe. The pepper flakes can also be eliminated if you prefer not to have the casserole on the spicy side. Here are some other delicious green bean casserole recipe ideas for your holidays this season:
