Ingredients Equipment Method Notes

Ingredients
  

  • 4 can (14.5 oz) cut green beans drained
  • 2 can (10.5 oz) condensed cream of mushroom soup
  • 1 cup milk
  • 1 tsp soy sauce
  • 0.25 tsp ground black pepper
  • 1.33 cup French fried onions divided

Equipment

  • 1 9x13-inch baking dish

Method
 

  1. Heat the oven to 350°F.
  2. Lightly grease a 9x13-inch baking dish.
  3. In a large bowl, stir together the cream of mushroom soup, milk, soy sauce, and black pepper.
  4. Fold in the green beans and 2/3 cup French fried onions.
  5. Spread the mixture in the prepared baking dish.
  6. Bake for 25 minutes, until hot and bubbling around the edges.
  7. Sprinkle the remaining 2/3 cup French fried onions evenly over the casserole.
  8. Bake for 5 minutes, until the onions are lightly golden.
  9. Let the casserole rest for 5 minutes before serving.

Notes

For a more even topping, spread the final layer of French fried onions evenly across the casserole. Refrigerate leftovers for 3–4 days; freezing is not recommended because the onions can lose their crispness. For a gluten-free version, use gluten-free cream of mushroom soup, French fried onions, and tamari.
