Recipe Information
Ingredients
- 1 pound fresh green beans
- 4 tablespoons unsalted butter
- 8 ounces white mushrooms, finely chopped
- 1 medium yellow onion, finely chopped
- 2 cloves garlic, minced
- 3 tablespoons all-purpose flour
- 1.5 cups chicken or vegetable broth
- 0.5 cups heavy cream
- 1 teaspoon soy sauce
- 0.5 teaspoons ground black pepper
- 1 teaspoon salt
- 1.5 cups crispy fried onions (store-bought or homemade)
Instructions
Preheat your oven to 375°F (190°C).
Bring a large pot of salted water to a boil. Add the green beans and blanch them for 4-5 minutes until bright green and slightly softened. Drain and transfer to an ice bath to stop the cooking. Once cool, drain thoroughly and set aside.
In a large skillet over medium heat, melt 2 tablespoons of butter. Add the mushrooms, onion, and garlic. Cook for 8-10 minutes, stirring frequently, until the onions are soft and the mushrooms have released their moisture.
Stir in the remaining 2 tablespoons of butter until melted. Sprinkle the flour over the vegetable mixture and cook for 1-2 minutes, stirring constantly to combine.
Slowly whisk in the chicken or vegetable broth and bring the mixture to a simmer. Stir in the heavy cream, soy sauce, salt, and black pepper. Cook for 3-4 minutes, stirring frequently, until the sauce thickens.
Remove the skillet from heat and fold in the blanched green beans, ensuring they’re well coated with the sauce.
Transfer the green bean mixture to a 9x13-inch baking dish. Spread it out evenly.
Scatter the crispy fried onions over the top in an even layer.
Bake in the preheated oven for 15-20 minutes, or until the casserole is bubbling around the edges and the onion topping is golden brown.
Remove from the oven and let it cool for 5 minutes before serving. Enjoy!
