Ingredients
- 4 cups fresh green beans, trimmed and cut
- 1 can cream of mushroom soup
- 1/2 cup milk
- 1 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt
- 1 cup shredded cheddar cheese
- 1 1/2 cups crispy fried onions
- 1 tablespoon butter
Step By Step Instructions

- Preheat your oven to 375 F. Lightly grease a medium baking dish so the casserole does not stick.
- Bring a pot of water to a boil. Add the green beans and cook for about 5 minutes until just tender. Drain well and set aside.
- In a large bowl, mix the cream of mushroom soup, milk, garlic powder, salt, and black pepper until smooth.
- Add the cooked green beans and half of the shredded cheese to the bowl. Stir gently so everything is coated in the creamy mixture.
- Pour the mixture into the prepared baking dish and spread it into an even layer.
- Sprinkle the remaining shredded cheese over the top.
- Bake for 20 minutes until the casserole is hot and bubbly around the edges.
- Remove the dish from the oven and sprinkle the crispy fried onions across the top.
- Return the casserole to the oven and bake for another 5 to 8 minutes until the onions are golden and crunchy.
Common Mistakes To Avoid
- Overcooking the beans. If the beans are boiled too long, they can become mushy during baking. Cook them just until tender.
- Adding onions too early. Crispy onions can burn if baked too long. Always add them near the end.
- Too much liquid. Extra milk can make the casserole watery. Stick to the listed amount.
- Skipping seasoning. Even simple easy casserole dishes need salt and seasoning for full flavor.
Tips For Success

- Use fresh green beans for the best texture and color.
- If using canned beans, drain them very well to avoid extra moisture.
