A grown up version of the classic green bean casserole!

1 lb green beans, cut into 1-2 inch pieces
1 small onion, cut into thin rings and separated
2 Tablespoons all purpose flour
Kosher salt and freshly ground pepper
2 1/2 Tablespoons olive oil
8oz button mushrooms, sliced
1 cup 1 percent milk

Boil, steam or roast green beans until tender. Set aside.

In a bowl, toss the onion with 1 tablespoon of the flour and ¼ teaspoon salt. Heat 1½ tablespoons of the oil in a large skillet over medium-high heat. Cook the onion, stirring, until golden brown, 1 to 2 minutes; transfer to a plate.

Wipe out the skillet and heat the remaining tablespoon of oil over medium-high heat. Cook mushrooms, stirring, until tender, 5 to 6 minutes.

Reduce heat to medium. Sprinkle the remaining tablespoon of flour over the mushrooms and cook, stirring, for 1 minute. Add the milk and ¼ teaspoon each salt and pepper. Simmer, stirring, until mixture begins to thicken, 1 to 2 minutes. Add green beans and cook until heated through, 3 to 4 minutes. Top with the onions.
