Preheat oven to 350°F (175°C). In a 9×9-inch baking dish, whisk the condensed cream of mushroom soup, milk, soy sauce, and ground black pepper until the mixture is glossy.
1 can condensed cream of mushroom soup, 0.75 cup milk, 1 tsp soy sauce, 0.25 tsp ground black pepper
Fold in the green beans, ensuring each piece is coated in the silky smooth sauce.
4 cups green beans
Bake uncovered for 25 minutes, watching the mixture bubble gently around the edges.
Topping
Sprinkle the crispy fried onions evenly over the casserole.
Bake 5 more minutes until the onions turn golden and crackle as they cool.
Notes
Allow the casserole to rest 10 minutes off heat to let the sauce set.Refrigerate leftovers within 2 hours and store for up to 3 days. Freeze the uncooked casserole (without topping) for up to 1 month.Reheat at 350°F for 10–15 minutes until warmed through; add onions and broil 1–2 minutes for extra crunch.
