Ingredients

1.5 lb Fresh Green Beans trimmed and cut

Gruyere Bechamel

3 tbsp Butter unsalted
3 tbsp Flour
2.5 cup Milk 2% or whole milk
1 cup Gruyere Cheese shredded
1/4 teaspoon Nutmeg freshly grated
Salt and Pepper to taste

Panko topping

2 tbs Butter unsalted, to toss the breadcrumbs
3/4 cup Panko Breadcrumbs

Instructions

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.
