Green Bean Casserole with Gruyere & Panko – an Alternative to the Traditional Green Bean Casserole Dish, made with a Cream of Mushroom Soup

If you grew up eating traditional green bean casserole with cream of mushroom soup and fried onions, this recipe might be a bit surprising for you. It doesn’t contain any canned mushroom soup, nor fried onions.

Personally, I didn’t grow up eating the traditional American casserole, and for some reason, the combination of beans with canned mushroom soup just doesn’t work for me. And don’t get me wrong, I love beans and I love mushrooms, but the combo just isn’t my thing. Maybe it’s the canned Cream of Mushroom Soup itself that I’m not a huge fan of. Perhaps if I hade made from scratch then I might like it…I don’t know.

With that said, I love green beans and I wanted to make a casserole that would have a European flair and be super delicious. I’m hoping that this will give some folks who, like me, aren’t fans of the inclusion of canned mushroom soup, a perfect holiday alternative.

Parboil your beans: trim and cut the beans and place them into boiling hot, well-salted water, for approximately 3-4 minutes. Drain and set aside.
Prepare your bechamel sauce: add butter to the skillet and melt it down on medium heat. Add flour and mix it well. Gradually start adding milk, until all is incorporated and the sauce is smooth.
Make the cheesy sauce: once your bechamel sauce is done, remove it from the heat. Shred your Grueryre cheese and add it to the sauce; mix well, until the cheese is melted and fully incorporated into the sauce. Season the sauce with freshly grated nutmeg, salt, and fresh pepper.
Make toasted breadcrumbs: add another pat of butter to a separate skillet and let it melt on medium-high heat. Add Panko breadcrumbs and then toss them with butter. Let them cook for a couple of minutes; often mixing, until crunchy. Once done, set the pan aside.
Prepare your casserole: Preheat your oven to 375ºF. Using a casserole dish (9″x 13″ will work), add a little sauce to the bottom of the dish. Then add beans. Pour the remaining sauce on top of the beans. Top it with toasted breadcrumbs and more Gruyere cheese. Place into the oven and bake for 25 minutes. Remove, let it cool slightly. Garnish with fresh herbs (chives or parsley) and serve.
