Ingredients You Need for Campbell’s Green Bean Casserole
- 1 can (10.5 oz) Campbell’s Condensed Cream of Mushroom Soup
- ¾ cup whole milk
- 1 teaspoon soy sauce
- ¼ teaspoon black pepper
- 4 cups cooked cut green beans (or two 14.5 oz cans, drained)

- ¼ teaspoon onion powder
Step-by-Step Guide to Making Campbell’s Green Bean Casserole
1. Preheat Your Oven
Set your oven to 350°F (175°C). Give it time to fully preheat before the dish goes in. A properly heated oven makes a big difference in how evenly this casserole cooks and how golden that topping gets.
2. Mix the Creamy Base
In a large mixing bowl, combine the Campbell’s Cream of Mushroom Soup, milk, soy sauce, garlic powder, onion powder, and black pepper. Stir everything together until it becomes a smooth, well-blended sauce. This creamy base is the heart of the whole recipe.
3. Add the Green Beans
Add your cooked or drained canned green beans directly into the soup mixture. Gently stir them in so every bean gets coated in that rich, savory sauce. Try not to break the beans too much — you want them to hold their shape after baking.
4. Stir in the First Round of Onions
Add ⅔ cup of the crispy fried onions into the green bean mixture. Fold them in gently. This step adds layers of crunch and flavor throughout the dish — not just on top. It’s one of those little tricks that makes a big difference.
5. Transfer to Your Baking Dish
Pour the entire mixture into a greased 1.5 to 2-quart baking dish. Spread it out evenly with a spatula. Make sure the green beans are distributed throughout so every serving has a good balance of beans, sauce, and onions.
6. Bake Uncovered
Place the dish in the preheated oven and bake uncovered for 25 minutes. You’ll know it’s ready when the sauce is hot and bubbling around the edges. The smell alone will tell you it’s doing something wonderful in there.
7. Add the Crispy Onion Topping
Remove the dish from the oven carefully. Sprinkle the remaining ⅔ cup of crispy fried onions evenly over the top. This creates that signature golden, crunchy crown that people fight over at the dinner table.
8. Return to Oven and Finish Baking
Put the dish back in the oven for another 5 minutes. This final step crisps up the onion topping beautifully. Keep a close eye on it so the onions don’t burn — golden brown is the goal, not dark brown.
9. Let It Rest and Serve
Remove from the oven and let it sit for about 5 minutes before serving. This helps the sauce settle and thicken slightly. Serve warm directly from the baking dish and watch it disappear within minutes.
Expert Tips & Variations
- Use fresh or frozen green beans for a more vibrant color and firmer texture compared to canned.
- Add shredded cheddar cheese on top before the final 5 minutes of baking for a cheesy twist.
- Make it ahead of time by preparing everything except the onion topping, refrigerating overnight, and adding the topping just before baking.
- Double the recipe easily — just use a larger 9×13-inch baking dish and add an extra 5 to 8 minutes of baking time.
- Use cream of chicken soup instead of mushroom for a slightly different but equally delicious flavor profile.
- Add crispy bacon bits to the mixture for a smoky, savory upgrade that everyone will love.
- Try it with mushrooms — sauté fresh sliced mushrooms with butter and garlic and stir them into the mix for extra depth.
- Go gluten-free by using a gluten-free cream of mushroom soup and gluten-free fried onions.
History or Fun Fact About the Dish
Here’s a fun piece of food history for you. The original green bean casserole recipe was created in 1955 by Dorcas Reilly, a home economist working in Campbell’s test kitchen in Camden, New Jersey. The goal was simple — create a quick, easy dish using pantry staples that most American families already had at home.
The recipe called for just six ingredients and took less than an hour from start to finish. It was an instant hit. Campbell’s began printing it on soup can labels, and from there, it spread across America like wildfire.
Today, it’s estimated that over 20 million families make this casserole every Thanksgiving. Campbell’s reportedly sells around 40 percent of its annual cream of mushroom soup production in the weeks leading up to the holiday. Dorcas Reilly’s original recipe card is now housed at the National Inventors Hall of Fame — a truly remarkable honor for a humble casserole.
Pairings & Complementary Recipes
This green bean casserole is a natural partner for so many main dishes and sides. Here are some ideas to build a complete, satisfying meal around it.
It goes beautifully alongside a classic roast turkey or honey-glazed ham. The creamy, savory flavors balance the richness of roasted meats perfectly. For a comforting weeknight dinner, pair it with baked chicken thighs or a simple pot roast. The casserole also works wonderfully next to mashed potatoes, buttered dinner rolls, and cranberry sauce for a full holiday spread. If you’re going vegetarian, serve it alongside stuffed bell peppers or a hearty mushroom loaf — it holds its own as a star side dish in that setting too.
Occasion or Event Ideas
One of the best things about this Campbell’s Green Bean Casserole recipe is how versatile it is for different occasions.
It’s practically required at Thanksgiving and Christmas dinners — it’s been a holiday table tradition for decades. But it also works wonderfully at potlucks, church gatherings, and neighborhood cookouts. Bring it to a friend’s house for dinner and you’ll be the most popular guest there.
It’s also a thoughtful dish to bring when someone is recovering from illness or has just had a new baby. Warm, familiar comfort food is always welcome in those moments. And honestly, it’s great enough to make on an ordinary Tuesday night when you just want something cozy and satisfying.
Storage and Reheating Tips
- Refrigerator: Store leftovers in an airtight container for up to 3 to 4 days.
- Freezer: Freeze the casserole (without the onion topping) for up to 2 months. Add fresh toppings when reheating.
- Reheating in the oven: Cover with foil and reheat at 350°F for 15 to 20 minutes until warmed through. Add fresh fried onions on top for the last 5 minutes.
- Reheating in the microwave: Heat individual portions in 60-second intervals, stirring between each, until hot throughout. Add a few crispy onions on top after reheating.
- Do not refreeze once the dish has been thawed and reheated.
- Avoid storing with the onion topping intact — the onions get soggy in the fridge. Add them fresh when you reheat.

Health Benefits
Green beans are the real nutritional hero in this dish. They’re packed with vitamin C, vitamin K, and folate, which support immune function, bone health, and cell growth. Green beans also offer a solid amount of dietary fiber, which supports healthy digestion and helps keep you feeling full for longer.
The cream of mushroom soup adds some protein and minerals like selenium, while mushrooms themselves contain antioxidants that help protect your cells from damage. Milk adds calcium and vitamin D, which are both essential for strong bones.
While this dish is definitely a comfort food and not a low-calorie option, it does contain real vegetables as its base. Compared to many other holiday side dishes loaded with butter and sugar, green bean casserole offers a more balanced nutritional profile. For a lighter version, you can use low-sodium soup, reduced-fat milk, and a smaller amount of fried onions on top without sacrificing too much of the classic flavor.
FAQs About Campbell’s Green Bean Casserole
Can I make Campbell’s Green Bean Casserole the night before? Absolutely! You can prepare the entire mixture, pour it into the baking dish, cover it with plastic wrap or foil, and refrigerate it overnight. Just hold off on adding the crispy onion topping until right before baking. When you’re ready, let the dish sit at room temperature for about 15 minutes, add the onion topping, and bake as directed. This makes it a huge time-saver on busy holiday mornings.
Can I use fresh green beans instead of canned? Yes, and many cooks actually prefer it. Fresh green beans give the casserole a firmer, more vibrant texture. Blanch them first — boil in salted water for about 5 minutes, then immediately transfer them to an ice bath to stop the cooking. Drain well before mixing into the casserole. Frozen green beans also work great and don’t need blanching — just thaw and drain them first.
Why is my green bean casserole watery? Watery casserole usually comes from excess moisture in the green beans. If you’re using canned beans, drain and pat them dry thoroughly before adding them. If using fresh or frozen, make sure to remove as much water as possible after cooking or thawing. Also, be sure you’re baking uncovered so that steam can escape and the sauce can thicken properly during cooking.
How do I keep the onion topping crispy? The key is to add the fried onion topping only in the last 5 minutes of baking — not at the start. If you put them on too early, they absorb moisture and turn soft. Also, make sure your casserole is truly hot and bubbling before you add the topping. A proper temperature helps the onions crisp up quickly and stay crunchy. If reheating leftovers, always add fresh onions after reheating, not before.
Can I double this green bean casserole recipe for a crowd? Easily! Simply double all the ingredients and use a 9×13-inch baking dish instead of the smaller casserole dish. Increase the initial baking time to 30 to 35 minutes before adding the topping, then return to the oven for another 5 to 7 minutes to crisp the onions. Keep an eye on it since larger portions take a bit more time to heat all the way through.
