Creating Creamy Green Bean Casserole is simple with the following steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Green Beans: In a large pot of boiling water, cook the green beans for 5-7 minutes until tender-crisp. Drain and set aside.
3. Mix Sauce: In a medium bowl, combine the cream of mushroom soup, milk, soy sauce, garlic powder, onion powder, salt, and pepper. Mix well until smooth.
4. Combine Ingredients: In a large mixing bowl, combine the green beans, half of the cheese, and the sauce mixture. Stir until the green beans are evenly coated.
5. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading it evenly.
6. Top with Cheese: Sprinkle the remaining cheese over the top of the casserole.
7. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the cheese is bubbly and golden.
8. Add Crispy Onions: Remove the casserole from the oven and sprinkle the crispy fried onions on top. Return to the oven for an additional 5-10 minutes for a crispy finish.
9. Cool Slightly: Allow the casserole to cool for 5-10 minutes before serving.
