Ingredients for Campbells Green Bean Casserole

To make this beloved side dish, you’ll need just a few simple ingredients:

• 1 can (10.5 oz) Campbell’s Condensed Cream of Mushroom Soup
• ½ cup milk
• 1 teaspoon soy sauce
• 4 cups cut green beans (fresh, canned, or frozen)
• 1⅓ cups crispy French fried onions, divided
• ¼ teaspoon black pepper, or to taste

What Kind of Green Beans Should You Use?

You have three great options:

• Canned: Drain 2 (14.5 oz) cans. Easiest and fastest.
• Frozen: Use one 16 oz bag. Thaw before adding.
• Fresh: About 1½ lbs, trimmed and blanched in boiling water for 2 minutes.

I personally love fresh green beans for the texture, but canned is perfect for last-minute prep.

How to Make Campbells Green Bean Casserole (Step-by-Step)

1. Prep the Dish

• Preheat your oven to 350°F.
• Spray a 9×9-inch casserole dish with nonstick cooking spray.
• If using fresh green beans, blanch them quickly in boiling water, then drain.

2. Mix the Sauce

• In a medium mixing bowl, combine the cream of mushroom soup, milk, and soy sauce.
• Stir well until smooth and no lumps remain.

3. Combine Everything

• Add the green beans to the sauce.
• Stir in 2/3 cup of crispy fried onions and the pepper.
• Mix thoroughly so every bean is coated.

4. Bake It

In the Oven:

1. Pour the mixture into your prepared baking dish.
2. Bake for 25 minutes at 350°F.
3. Stir gently, then sprinkle the remaining onions over the top.
4. Return to the oven and bake for another 5 minutes, or until golden and bubbly.

In the Air Fryer:

1. Add the mixture to a heat-safe dish that fits in your air fryer.
2. Air fry at 350°F for 10 minutes.
3. Stir, then top with remaining onions.
4. Air fry for another 2 minutes to crisp them up.

The air fryer is great if your oven is packed on a busy holiday.

Recipe Tips from My Kitchen

• Want more flavor? Add a dash of garlic powder or onion powder.
• Extra creamy? Stir in ½ cup of shredded cheddar or Swiss cheese.
• No soy sauce? Swap in Worcestershire for a deeper savory flavor.
• Make it ahead: Assemble (without onions on top) and refrigerate. Add onions and bake just before serving.
• Feeding a crowd? Double the recipe and use a 9×13-inch pan.

Reader-Favorite Variations

• Green bean casserole with frozen green beans — still crisp, easy to prep.
• Green bean casserole with fresh green beans — more bite and color.
• Campbell’s green bean casserole without mushroom soup — sub in cream of chicken or cream of celery.
• Cheesy twist — add a layer of cheese under the final onion topping.

My sister swears by the cheddar version. We had a “casserole-off” last year and both disappeared in minutes.
