Creating the perfect Classic Green Bean Casserole is easy when you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Blanch Beans: Boil water in a large pot. Add the green beans and blanch for about 5 minutes until bright green. Drain and set aside.
3. Mix Filling: In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, and black pepper. Stir until well mixed.
4. Combine Beans: Add the blanched green beans and half of the crispy fried onions to the soup mixture. Stir until the beans are evenly coated.
5. Add Cheese: If using, fold in the shredded cheddar cheese for a richer flavor.
6. Transfer to Dish: Pour the mixture into a greased 2-quart baking dish.
7. Bake: Place in the preheated oven and bake for 25-30 minutes or until the casserole is bubbly and heated through.
8. Add Topping: Remove from the oven, and sprinkle the remaining crispy fried onions on top. Return to the oven for an additional 5 minutes or until the onions are golden brown.
9. Cool Slightly: Allow to cool for about 5 minutes before serving, which will help the layers set a bit.
10. Serve Warm: Enjoy your Classic Green Bean Casserole while it’s warm and inviting!
