- 1½ pounds fresh green beans, trimmed
- 3 tablespoons butter
- 8 ounces mushrooms, sliced
- 2 garlic cloves, minced
- 3 tablespoons all-purpose flour
- 1½ cups milk
- ½ cup chicken or vegetable broth
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon onion powder

You can adjust the cheese depending on your preference. Cheddar creates a stronger flavor, mozzarella gives a stretchy texture, and Parmesan adds a savory finish.
How to Make Green Bean Casserole
1. Prepare the Green Beans
If using fresh green beans, wash and trim the ends. Bring a large pot of salted water to a boil and cook the beans for about 4–5 minutes, until they are bright green and slightly tender.
Drain them immediately and transfer them to a bowl of ice water. This stops the cooking process and helps maintain their color and texture.
If you’re using frozen green beans, simply thaw and drain them well. Canned green beans can also be used after draining thoroughly.
2. Make the Creamy Sauce
Preheat your oven to 375°F (190°C).
Melt the butter in a large skillet over medium heat. Add the mushrooms and cook for 5–6 minutes until they soften and release some of their moisture.
Add the minced garlic and cook for another 30 seconds.
Sprinkle the flour over the mushrooms and stir continuously for about 1 minute. Slowly pour in the milk and broth while whisking to prevent lumps.
Season with salt, pepper, and onion powder. Continue cooking for several minutes until the sauce thickens.
Stir in the Parmesan cheese until melted and smooth.
3. Combine Everything
Add the prepared green beans to the skillet and gently toss them with the creamy sauce.
Transfer the mixture to a greased 9×13-inch baking dish. Spread it evenly.
For a cheesy green bean casserole, sprinkle the shredded mozzarella or cheddar evenly over the top.
4. Add the Crispy Topping
Bake the casserole for about 20 minutes.
Remove the dish from the oven and sprinkle the crispy fried onions over the top. Return it to the oven for another 5–10 minutes, until the cheese is melted and the topping is golden and crisp.
Let the casserole rest for a few minutes before serving.
Green Bean Casserole From Scratch
Making green bean casserole from scratch is easier than it may seem. Instead of using canned condensed soup, this recipe creates a simple homemade cream sauce with butter, mushrooms, flour, milk, broth, and Parmesan.
The homemade sauce has a fresh savory flavor and can easily be adjusted. Add extra garlic for more depth, a pinch of nutmeg for warmth, or additional black pepper for a bolder taste.
If you want to make the recipe even more homemade, you can prepare your own crispy onion topping rather than using packaged fried onions.
Tips for the Best Casserole
Don’t overcook the beans: Fresh green beans should remain slightly firm before they go into the oven.
Drain thoroughly: Excess water can make the creamy sauce thin.
Don’t add the onions too early: Adding crispy onions toward the end helps keep them crunchy.
Use freshly grated cheese: It melts more smoothly and creates a better texture.
Let it rest: A few minutes of resting helps the sauce settle before serving.
Healthy Green Bean Casserole
For a healthy green bean casserole, you can make several simple changes without giving up the creamy texture.
Use low-fat milk instead of heavy cream and increase the amount of fresh green beans. You can also reduce the butter and cheese slightly while adding more mushrooms, garlic, and herbs for flavor.
For a lighter topping, use toasted breadcrumbs mixed with a small amount of Parmesan instead of a large amount of fried onions.
These changes can make the casserole feel lighter while keeping it satisfying.
