Irresistible Campbell’s Green Bean Casserole Recipe
Introduction
This classic Green Bean Casserole combines tender green beans with a creamy mushroom sauce and a crispy fried onion topping. It’s a comforting side dish perfect for holidays or any family dinner. Using Campbell’s condensed cream of mushroom soup gives it that familiar, nostalgic flavor everyone enjoys.

Ingredients
- 1/2 cup milk (whole milk works best for creaminess)
- 1/4 tsp ground black pepper
- 1 tsp soy sauce (adds depth without overpowering)
- 1 can condensed cream of mushroom soup (Campbell’s recommended)
- 4 cups green beans (fresh, frozen, or canned; thawed if frozen)
- 1 1/3 cups crispy fried onions (French’s brand traditional; divided)
Instructions
- Step 1: Prepare your green beans by trimming and cutting fresh beans into 2-inch pieces and blanching briefly in salted boiling water, or thaw and drain frozen beans, or drain canned beans well. Preheat your oven to 350°F (or set your air fryer to the same temperature). Divide the fried onions into two portions: about 2/3 cup for mixing and 1/3 cup reserved for topping.
- Step 2: In a large bowl, whisk together the condensed cream of mushroom soup, milk, and soy sauce until smooth and well combined. The soy sauce adds umami depth without overpowering the flavor.
- Step 3: Add the prepared green beans, 2/3 cup of fried onions, and ground black pepper to the soup mixture. Gently fold until the green beans are evenly coated and the onions are distributed without breaking them up.
- Step 4: Transfer the mixture to a 9×9-inch baking dish, spreading it evenly. Bake in the preheated oven for 25 minutes (or 10 minutes in an air fryer) until bubbling and heated through.
- Step 5: Remove the casserole, gently stir to redistribute the sauce, then top with the reserved 1/3 cup of fried onions. Return to the oven and bake an additional 5 minutes (or 2 minutes in an air fryer) until the onions are golden and crispy.
Tips & Variations
- For extra flavor, add a handful of shredded cheddar cheese to the sauce before baking.
- Use low-sodium soy sauce if you want to control saltiness.
- Fresh green beans provide the best texture, but frozen or canned can be convenient options.
- Reserve some fried onions for garnish on top to ensure maximum crispiness.
Storage
Store leftover casserole covered in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through to keep the topping crispy. Avoid microwaving to prevent sogginess.

FAQs
Can I make this casserole ahead of time?
Yes, you can assemble the casserole a day before baking. Keep it covered in the fridge and add the topping just before baking to maintain crispiness.
Can I use a different type of mushroom soup?
While Campbell’s condensed cream of mushroom soup is recommended for classic flavor, any creamy mushroom soup can be used depending on your preference.

Description
This irresistible Campbell’s Green Bean Casserole is a classic comfort dish featuring tender green beans enveloped in a creamy mushroom sauce enhanced with soy sauce for umami depth, all topped with crispy fried onions. Perfect for holiday dinners or family meals, this easy casserole delivers a delightful contrast of creamy and crunchy textures.
Ingredients
For the Casserole:
- 1/2 cup milk (whole milk works best for creaminess)
- 1/4 tsp ground black pepper
- 1 tsp soy sauce
- 1 can condensed cream of mushroom soup (Campbell’s recommended)
- 4 cups green beans (fresh, frozen, or canned; thawed if frozen)
For the Topping:
- 1 1/3 cups crispy fried onions (French’s brand recommended; divided into 2/3 cup for mix-in and 1/3 cup for garnish)
Instructions
- Prepare Your Ingredients and Preheat Equipment: If using frozen green beans, thaw completely and drain excess liquid. For fresh green beans, trim, cut into 2-inch pieces, and blanch briefly in salted boiling water before draining. Drain canned beans well. Preheat oven to 350°F or air fryer to the same temperature. Divide fried onions into two portions: 2/3 cup for the casserole and 1/3 cup reserved for topping.
- Build the Creamy Soup Base: In a large bowl, whisk together condensed cream of mushroom soup, milk, and soy sauce until smooth and well combined to add subtle umami flavor without overpowering the dish.
- Combine Green Beans with Sauce and Seasonings: Add drained green beans, 2/3 cup fried onions, and ground black pepper to the soup mixture. Gently fold until green beans are evenly coated and onions are well distributed, taking care not to overmix to keep onions crispy.
- Transfer to Baking Dish and Initial Bake: Pour mixture into a 9×9-inch baking dish and spread evenly. Bake in preheated oven for 25 minutes, or 10 minutes if using an air fryer, until bubbling and heated through.
- Stir and Top with Crispy Onion Garnish: Remove casserole and gently stir. Spread reserved 1/3 cup fried onions evenly over the top. Return to oven and bake an additional 5 minutes (2 minutes in air fryer) until onions are golden and casserole bubbles gently, creating a perfect creamy and crunchy contrast.
Notes
- Use whole milk for best creaminess, though other milk types can be substituted.
- Fresh green beans can be blanched prior to baking for best texture; frozen should be fully thawed and drained.
- Soy sauce adds umami without overpowering; adjust to taste if preferred less salty.
- French’s crispy fried onions are traditional, but any crispy fried onion brand can be used.
- For quicker cooking, use an air fryer at 350°F, adjusting bake times as noted.
- Reserve some onions before mixing so topping stays crispy and fresh.
