An easy, prep-ahead side dish for holidays and weeknight dinners!
Preheat oven to 350°F. Spray a 1 ½ -quart baking dish with cooking spray and set aside. Place frozen green beans in a large microwave-safe bowl. Add a splash of water, cover, and microwave just until crisp-tender (about 5 minutes). Drain and return green beans to the bowl.
Add condensed soup, milk, soy sauce, pepper, and ⅔ cup of the fried onions to the bowl with the green beans; stir to combine.
Transfer the green bean mixture to the prepared baking dish.
Bake, uncovered, for 25 minutes. Stir, sprinkle remaining ⅔ cup of fried onions on top, and bake until the filling it hot and bubbly and the topping is lightly browned, about 5 more minutes.
