Green bean casserole from scratch is the ultimate Thanksgiving side dish. Made with mushrooms, butter, fried onions, and a homemade cream sauce.
Serve this along with your Thanksgiving Roast Turkey and Candied Yams!
The great thing about this green bean casserole recipe is that you can make it ahead of time and reheat it up when you want to serve it. I used frozen green beans but feel free to use fresh green beans instead.
Green bean casserole is a dish that consists of green beans, cream of mushroom soup, and french fried onions. Although, I prefer making my own mushroom cream sauce from scratch.
Campbell’s created this dish in 1955 and nowadays it is a staple during the holidays. Classic green bean casserole is just as important as creamy mashed potatoes and sweet potato casserole on Thanksgiving day.
