Ingredients

16 ounce package frozen French-cut green beans (or see Variations section below for substitutes)
1 (10.5 ounce) can condensed cream of mushroom soup
¾ cup milk
1 teaspoon less-sodium soy sauce
⅛ teaspoon ground black pepper
1 ⅓ cups crispy fried onions, divided

Instructions

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.

Notes

Make-Ahead Instructions: This dish can be assembled up to 2 days in advance. Just prepare as directed, but leave off the remaining fried onions that go on top at the end. Cover with foil and refrigerate until ready to bake. Allow the dish to sit on the counter at room temperature for at least 30 minutes before baking. Bake according to the recipe instructions, adding a few extra minutes to the cooking time if the casserole is really cold when it goes into the oven.
