Recipe
Green bean casserole is a classic American side dish that has graced holiday tables for generations. This comforting and creamy casserole combines tender green beans with a rich mushroom sauce, all topped with crispy fried onions for a delightful texture contrast.
Originally created by Campbell's Soup Company in 1955, this dish has become a beloved staple in many households. Its simplicity and crowd-pleasing flavor make it a perfect addition to Thanksgiving dinners, potlucks, and family gatherings throughout the year.
- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup milk
- 1 teaspoon soy sauce
- 1/4 teaspoon black pepper
- 4 cups cooked cut green beans
- 1 1/3 cups French's Crispy Fried Onions, divided
- 1/4 cup shredded cheddar cheese (optional)
Preheat the oven to 350°F (175°C). In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, and black pepper. Stir in the green beans and 2/3 cup of the crispy fried onions. Transfer the mixture to a 1 1/2-quart casserole dish.
Bake for 25 minutes, then remove from the oven and top with the remaining fried onions and shredded cheese if using. Return to the oven and bake for an additional 5 minutes, or until the onions are golden brown and crispy.
For the best results, use fresh green beans instead of canned ones. Blanch them in boiling water for 3-5 minutes before adding them to the casserole mixture.
To make this dish ahead of time, prepare the casserole up to the point of baking, cover it tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to serve, remove from the refrigerator 30 minutes before baking and add an extra 5-10 minutes to the initial baking time.
Cooking Steps
You're about to embark on the cooking journey for your Green Bean Casserole, and it's easier than you might think.
First, you'll preheat your oven and mix the beans with soup, creating the base of your casserole.
Then, you'll add the crispy fried onions and bake it all together, resulting in a delicious, hot dish that's ready to be enjoyed by all.
Step 1. Preheat Oven to 350°F

Before diving into the preparation of your green bean casserole, turn on the oven and set it to 350°F (175°C). This step is crucial for ensuring your casserole cooks evenly and achieves that perfect golden-brown crust.
Preheating typically takes about 10-15 minutes, giving you ample time to gather ingredients and start assembling your dish.
While the oven's warming up, here's why 350°F is the ideal temperature for this classic side:
- It's hot enough to cook the casserole thoroughly without burning the top
- It allows the flavors to meld together slowly
- It creates a crispy texture for the French fried onions on top
Step 2. Mix Beans and Soup

Now that your oven is preheating, it's time to mix the main ingredients. You'll need two key components for this classic casserole: green beans and cream of mushroom soup.
Start by draining two 14.5-ounce cans of green beans, or if you're using fresh beans, make sure they're cleaned and trimmed. Pour the beans into a large mixing bowl.
Next, open a 10.5-ounce can of cream of mushroom soup and add it to the bowl with the green beans. This condensed soup will create a rich, creamy base for your casserole. As you mix, you'll notice how the soup coats the beans, ensuring every bite will be full of flavor.
For extra creaminess and flavor, consider these additions:
- 1/4 cup of milk to thin the soup slightly
- 1/2 teaspoon of soy sauce for umami depth
- 1/4 teaspoon of black pepper for a subtle kick
Use a spatula or large spoon to gently fold these ingredients together until they're well combined.
Be careful not to mash the green beans; you want them to retain their shape and texture in the finished dish.
Step 3. Add Crispy Fried Onions

The next step is to incorporate the crispy fried onions, which give the casserole its signature crunch and flavor. You'll want to use about 1 1/3 cups of these golden delights, reserving some for the topping later. Gently fold the onions into the green bean and soup mixture, ensuring they're evenly distributed throughout.
These crispy fried onions aren't just any ordinary ingredient. They're a key component that elevates your casserole from good to great. Here's why they're so important:
- Texture: They provide a satisfying crunch that contrasts beautifully with the creamy soup and tender beans.
- Flavor: Their savory, slightly sweet taste complements the other ingredients perfectly.
- Visual appeal: The golden-brown color adds an appetizing look to your dish.
When adding the onions, be careful not to crush them too much. You want to maintain their crispy texture as much as possible.
Once you've mixed them in, smooth the top of the casserole with a spatula. This will create an even surface for the final layer of onions you'll add later.
Step 4. Bake for 30 Minutes

With your casserole assembled, it's time to bake it to perfection. Preheat your oven to 350°F (175°C) and position the rack in the middle. Place your casserole dish on a baking sheet to catch any potential spills, then slide it into the preheated oven.
Set your timer for 30 minutes and let the magic happen. During this time, the flavors will meld together, and the crispy onions will turn a beautiful golden brown. The cream of mushroom soup will bubble and thicken, coating the green beans in a velvety sauce.
Keep an eye on your casserole as it bakes. If you notice the top browning too quickly, loosely cover it with aluminum foil to prevent burning.
After 30 minutes, check for doneness by inserting a knife into the center. It should come out hot, and the casserole should be bubbling around the edges.
Once it's finished baking, carefully remove the dish from the oven using oven mitts. Let it cool for 5-10 minutes before serving. This resting period allows the casserole to set slightly, making it easier to portion and serve.
Step 5. Serve Hot and Enjoy

Serving time has arrived for your delicious green bean casserole. After removing it from the oven, let it cool for about 5 minutes to allow the sauce to thicken slightly. This brief resting period also ensures you won't burn your tongue on the first bite!
Now, it's time to plate your masterpiece. Here are some serving suggestions:
- Use a large spoon to scoop generous portions onto plates
- Garnish with extra crispy fried onions for added crunch
- Pair with your main course, such as roasted turkey or ham
Remember, green bean casserole is best enjoyed hot. The combination of creamy sauce, tender green beans, and crispy onion topping is at its peak when warm. If you're serving buffet-style, consider using a warming tray to maintain the ideal temperature.
As you savor each bite, you'll appreciate how the flavors have melded during baking. The mushroom soup has transformed into a rich, velvety sauce, while the green beans retain a slight crispness.
Don't be surprised if your guests ask for seconds – this classic dish is known for its comforting, crowd-pleasing appeal!
Final Thoughts
Green bean casserole remains a beloved holiday staple for good reason. It's a dish that perfectly balances comfort and tradition with ease of preparation. As you've seen, making this classic side doesn't require advanced culinary skills, yet it never fails to impress guests and satisfy cravings.
Remember, the beauty of green bean casserole lies in its versatility. Don't be afraid to experiment with different variations or add your own personal touch. You might try using fresh green beans instead of canned, or swapping out the cream of mushroom soup for a homemade sauce. Some cooks even like to add bacon or cheese for extra flavor and richness.
Whether you're preparing this dish for a holiday gathering or a cozy family dinner, it's sure to be a hit. The combination of crisp-tender green beans, creamy sauce, and crunchy fried onions creates a harmonious blend of textures and flavors that's hard to resist.
