Ingredients
  

Casserole Base
  • 4 cups green beans fresh, canned (drained), or frozen (thawed)
  • 1 can cream of mushroom soup 10.5 oz, or homemade sauce
  • 1/2 cup milk
  • 1 tsp soy sauce for depth of flavor
  • 1/4 tsp black pepper to taste

Equipment

  • Casserole dish
  • Mixing bowl
  • Oven

Method
 

  1. Preheat oven to 350°F (175°C).
  2. In a mixing bowl, combine green beans, cream of mushroom soup, milk, soy sauce, black pepper, and half of the fried onions. Stir until evenly coated.
  3. Transfer the mixture to a greased casserole dish.
  4. Bake uncovered for 25 minutes until bubbling.
  5. Stir gently, then sprinkle the remaining fried onions (and cheese, if using) over the top.
  6. Return to the oven for 10 minutes until onions are golden and crispy.
  7. Let sit for 5 minutes before serving.

Notes

You can substitute French fried onions with buttered panko breadcrumbs, crispy shallots, or crushed crackers. For fresh beans, blanch 3–4 minutes before baking. Rinse canned beans to reduce sodium if preferred.
