Ingredients

1 (10.5 oz) can cream of mushroom soup

¾ cup whole milk

½ teaspoon soy sauce

¼ teaspoon black pepper

2 (14.5 oz) cans green beans, drained (any style – French cut recommended)

1½ cups French’s crispy fried onions, divided

Instructions

Preheat oven to 350°F.

In a large bowl, whisk together cream of mushroom soup, milk, soy sauce, and black pepper until smooth.

Stir in drained green beans and ½ cup of the crispy fried onions until fully combined.

Pour mixture into a baking dish and bake for 30 minutes.

Remove from oven, stir gently, then top with remaining 1 cup of fried onions.

Return to oven and bake an additional 5–10 minutes, until onions are golden brown and crisp.

Serve hot.

Notes

Can be made ahead and frozen: Assemble without final onion topping, wrap tightly, and freeze up to 2 weeks. Thaw overnight in the fridge before baking.

Use fresh or frozen green beans if preferred—blanch and drain well before mixing.

Add ¼ tsp garlic powder or a pinch of nutmeg for added depth of flavor.
