  • In a large bowl, mix together the cream of mushroom soup, milk, soy sauce, garlic powder, and black pepper. Taste and adjust seasoning with salt if needed.
  • Stir in the green beans and about half of the French fried onions. If adding cheese, mix it in now.
  • Pour the mixture into the prepared dish and spread it evenly.
  • Bake for 20-25 minutes until hot and bubbly around the edges.
  • Remove from the oven and add the remaining French fried onions on top. Bake for an additional 5-10 minutes until the topping is golden brown.

Notes

Make ahead by mixing all but the final onion topping and refrigerating overnight. Bring to room temperature before baking. Can be made in a slow cooker; just adjust the cooking time.
