Green bean casserole is a classic Thanksgiving side dish that is a regular at any holiday table. I put a fresh twist on this traditional side that will have even the green bean casserole disapprovers changing their mind. This recipe for sheet pan green bean casserole has roasted green beans that don’t get mushy, a fresh homemade creamy mushroom sauce, and of course gets topped with plenty of everyone’s favorite French-fried onion strings! This updated version of green bean casserole is easy to make, and you are going to love the fresh flavors.

There is absolutely nothing wrong with the classic version of green bean casserole, but if you happen to be someone who doesn’t like canned green beans that don’t have texture, then you will love this sheet pan version. I like to roast the green beans so that they still have vibrant color and good texture because I think it is a nice contrast to the creamy mushroom sauce and crispy onions.

I also am obsessed with the homemade creamy mushroom sauce and it truly blows the canned version out of the water. The flavors are so fresh, and the mushrooms get nice and caramelized so they add such great flavor and texture. The sauce is made with a few simple ingredients and doesn’t require much effort, so in my opinion it’s 100% worth it to make this homemade version. I still use good ole store-bought French-fried onions, because they are delicious and it really cuts down on time!
