Ingredients Method Notes

Ingredients
  

  • 2 14.5-oz cans cut green beans drained, or 4 cups cooked fresh beans
  • 1 10.5-oz can condensed cream of mushroom soup
  • ¾ cup whole milk
  • 1 tsp soy sauce
  • ¼ tsp garlic powder
  • ¼ tsp black pepper
  • 1⅓ cups French fried onions divided (from a 6-oz container)
  • ½ cup shredded sharp cheddar optional

Method
 

  1. Heat the oven to 350°F. Grease a 1½-quart baking dish.
  2. In the baking dish, stir together the soup, milk, soy sauce, garlic powder and pepper until smooth.
  3. Stir in the green beans and ⅔ cup of the fried onions.
  4. Bake uncovered for 25 minutes, until bubbling at the edges.
  5. Stir, sprinkle with the cheddar (if using) and the remaining ⅔ cup fried onions, and bake 5 minutes more until the onions are golden. Serve hot.

Notes

For fresh beans: trim 1½ lb green beans, cut in 2-inch pieces, boil 5 minutes, then plunge in ice water and drain well. Make ahead: assemble without the onions up to 1 day ahead and stir in the first ⅔ cup just before baking; add 10 minutes to the first bake. Leftovers keep 3 days.
