Green bean casserole with Worcestershire sauce is a creamy and savory dish made with green beans, cream of mushroom soup, and Worcestershire sauce, and topped with crispy fried onions for a crunchy finish.
Blanch the green beans in boiling water for 3-4 minutes, then transfer them to an ice bath to stop cooking. Drain and set aside.
In a mixing bowl, combine the cream of mushroom soup, milk, Worcestershire sauce, garlic powder, salt, and pepper. Mix until smooth.
Grease a 9×13-inch baking dish with butter. Spread the blanched green beans evenly in the dish. Pour the sauce mixture over the beans and stir gently to coat.
Sprinkle 1 cup of crispy fried onions evenly over the casserole.
Preheat the oven to 350°F (175°C). Bake the casserole for 25-30 minutes, or until bubbling and heated through.
Remove the casserole from the oven and sprinkle the remaining ½ cup of crispy fried onions on top. Return to the oven and bake for an additional 5 minutes, or until the onions are golden and crispy.
