In this green bean casserole, tender green beans, cheese, and crispy onions are tossed in a delicious creamy sauce and then baked!
Preheat the oven to 350°F.
Bring a medium pot of salted water to a boil. Add the frozen green beans and boil until tender crisp, about 2 to 3 minutes.
In a large bowl, combine green beans with soup, milk, soy sauce, pepper, salt, 1 cup of crispy onions, and cheese if using (see notes). Transfer to a 2-quart baking dish.
Bake uncovered for 30 to 35 minutes or bubbly.
Remove from oven and stir. Top with remaining onions and return to oven for an additional 10 minutes or until golden.
