Equipment
- Large mixing bowl
- 1.5 to 2-quart baking dish
- Measuring cups and spoons
- Wooden spoon or silicone spatula
- Oven mitts
- Aluminum foil optional
- Colander for draining green beans
Ingredients
- 1 can (10.5 oz) Campbell's Condensed Cream of Mushroom Soup
- 3/4 cup whole milk
- 1 teaspoon soy sauce
- 1/4 teaspoon black pepper
- 4 cups cooked cut green beans, or two 14.5 oz cans, drained
- 1 1/3 cups French's crispy fried onions, divided, use 2/3 cup in the mix and 2/3 cup for topping
- 1/2 teaspoon garlic powder
- 1/4 teaspoon onion powder
Instructions
Preheat the Oven
- Preheat your oven to 350°F (175°C). Lightly grease a 1.5 to 2-quart baking dish to prevent sticking. Allow the oven to fully heat so the casserole cooks evenly and develops a perfectly creamy texture.
Prepare the Creamy Base
- In a large mixing bowl, combine the cream of mushroom soup, whole milk, soy sauce, garlic powder, onion powder, and black pepper. Stir thoroughly until the mixture becomes smooth, creamy, and well blended.
Add the Green Beans
- Add the cooked or well-drained canned green beans into the creamy soup mixture. Gently fold them in using a spatula, ensuring every bean is evenly coated while keeping their shape intact.
Mix in the First Onion Layer
- Stir in two-thirds cup of the crispy fried onions into the green bean mixture. Mix gently so the onions distribute evenly, adding flavor and a subtle crunch throughout the casserole before baking.
Assemble the Casserole
- Transfer the prepared mixture into the greased baking dish. Spread it evenly with a spatula, ensuring the beans, sauce, and onions are well distributed so each serving has a balanced texture and flavor.
Bake the Casserole
- Place the baking dish in the preheated oven and bake uncovered for 25 minutes. The casserole is ready when the sauce becomes hot and bubbly around the edges and the aroma fills your kitchen.
Add the Crispy Topping
- Carefully remove the dish from the oven using oven mitts. Sprinkle the remaining two-thirds cup of crispy fried onions evenly over the top, creating the signature golden and crunchy finishing layer.
Finish Baking
- Return the casserole to the oven and bake for an additional 5 minutes. This short baking time crisps the onion topping beautifully while keeping it golden and flavorful without burning.
Rest and Serve
- Remove the casserole from the oven and allow it to rest for about 5 minutes before serving. This brief resting time helps the sauce thicken slightly and makes serving easier and more enjoyable.
Notes
- Use fresh or frozen green beans for better texture and color.
- Add shredded cheddar cheese before the final baking for a cheesy variation.
- Prepare the casserole ahead of time and refrigerate, adding the onion topping just before baking.
- Store leftovers in the refrigerator for up to 4 days and reheat at 350°F until warmed through.
- For freezing, omit the onion topping and add fresh onions when reheating for best crispness.
