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

Scale

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.
