Ingredients

Use condensed soup, rather than ready-to-serve soup. Check your product labels for allergens.
Cooking Steps
Get the oven and dish ready.
Preheat the oven to 350°F. Have a 1½-quart oven-safe casserole dish ready, with a rack near the center of the oven.
Mix the creamy base.
Combine the soup, milk, soy sauce and pepper in the baking dish. Fold in the cooked green beans and ⅔ cup of the fried onions.
Bake until hot.
Bake for about 25 minutes, until the mixture is hot and bubbling. Stir carefully, then spread the reserved ⅔ cup of onions over the surface.
Finish the topping.
Return the dish to the oven for about 5 minutes, until the onions are golden. Check that the center reaches 165°F with a food thermometer; continue cooking if needed.
Serve it as a side.
Use oven mitts to move the hot dish to a heat-safe surface. Serve alongside the rest of your meal. Cooking time can vary with your oven, dish and starting temperature.
