Ingredients



For the topping:

2 medium onions, thinly sliced

1/4 cup all-purpose flour

2 tablespoons panko bread crumbs

1 teaspoon kosher salt

Nonstick cooking spray

For beans and sauce:

2 tablespoons plus 1 teaspoon kosher salt, divided

1 pound fresh green beans, rinsed, trimmed and halved

2 tablespoons unsalted butter

12 ounces mushrooms, trimmed and cut into 1/2-inch pieces

1/2 teaspoon freshly ground black pepper

2 cloves garlic, minced

1/4 teaspoon freshly ground nutmeg

2 tablespoons all-purpose flour

1 cup chicken broth

1 cup half-and-half



Directions



Preheat the oven to 475 degrees F.



Combine the onions, flour, panko and salt in a large mixing bowl and
toss to combine. Coat a sheet pan with nonstick cooking spray and
evenly spread the onions on the pan. Place the pan on the middle rack of
the oven and bake until golden brown, approximately 30 minutes. Toss
the onions 2 to 3 times during cooking. Once done, remove from the oven
and set aside until ready to use. Turn the oven down to 400 degrees F.



While the onions are cooking, prepare the beans. Bring a gallon of
water and 2 tablespoons of salt to a boil in an 8-quart saucepan. Add
the beans and blanch for 5 minutes. Drain in a colander and immediately
plunge the beans into a large bowl of ice water to stop the cooking.
Drain and set aside.



Melt the butter in a 12-inch cast iron skillet set over medium-high
heat. Add the mushrooms, 1 teaspoon salt and pepper and cook, stirring
occasionally, until the mushrooms begin to give up some of their liquid,
approximately 4 to 5 minutes. Add the garlic and nutmeg and continue to
cook for another 1 to 2 minutes. Sprinkle the flour over the mixture
and stir to combine. Cook for 1 minute. Add the broth and simmer for 1
minute. Decrease the heat to medium-low and add the half-and-half. Cook
until the mixture thickens, stirring occasionally, approximately 6 to 8
minutes.



Remove from the heat and stir in 1/4 of the onions and all of the
green beans. Top with the remaining onions. Place into the oven and bake
until bubbly, approximately 15 minutes. Remove and serve immediately.
