Equipment

  • Large pot for boiling water
  • Colander for draining the beans
  • Medium-sized saucepan for making the mushroom sauce
  • Baking dish for assembling and baking the casserole
  • Mixing bowls for combining ingredients
  • Whisk for stirring and blending the sauce
  • Knife and cutting board for chopping onions and mushrooms
  • Oven for baking the casserole
  • Aluminum foil for covering the casserole while baking

Ingredients

  • 1 1/2 pounds fresh green beans, ends trimmed and halved
  • 2 tablespoons unsalted butter
  • 12 ounces cremini mushrooms, thinly sliced
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 2 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • 1 cup chicken broth
  • 1 cup heavy cream
  • 1 cup crispy fried onions

Instructions

  • Preheat your oven to 375°F (190°C).
  • Heat a generous amount of salted water in a large pot until it begins to boil. Add the green beans and cook for about 5 minutes, until they are bright green and tender-crisp. Drain the beans and immediately plunge them into a bowl of ice water to stop the cooking process. Set aside.
  • In a saucepan of medium size, allow the butter to melt over medium heat. Add the sliced mushrooms, salt, and black pepper. Cook for about 5 minutes, until the mushrooms release their liquid and start to brown.
  • Add the minced garlic to the mushrooms and cook for an additional 1 minute.
  • Dust the mushroom mixture with flour and stir thoroughly to evenly coat. Cook for 1 minute, stirring constantly.
  • Slowly pour in the chicken broth, whisking constantly to prevent any lumps from forming. Add the heavy cream and continue whisking until the mixture is smooth and thickened about 5 minutes.
  • Drain the green beans and transfer them to a large mixing bowl. Pour the mushroom sauce over the beans and stir gently to combine.
  • Move the green bean mixture into a baking dish that has been greased. Spread the crispy fried onions evenly over the top of the casserole.
  • Place aluminum foil over the dish and bake for a duration of 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the onions are golden brown and the casserole is bubbling.
  • Remove the casserole from the oven and let it cool for a few minutes before serving.
