Irresistible Campbell’s Green Bean Casserole Recipe
Introduction
This Irresistible Campbell’s Green Bean Casserole is a classic comfort dish that’s creamy, flavorful, and topped with crispy fried onions. Perfect for holidays or weeknight dinners, it combines tender green beans with a savory mushroom sauce for an easy crowd-pleaser.

Ingredients
- 1 can condensed cream of mushroom soup (10.5 oz)
- 1/2 cup milk
- 1 tsp soy sauce
- 4 cups cut green beans (from 2 cans, 1 lb fresh, or one 16 oz frozen package)
- 1/4 tsp ground black pepper
- 1 1/3 cups crispy french fried onions, divided
Instructions
- Step 1: If using frozen green beans, thaw completely and drain excess liquid; if using fresh, trim and cut into 2-inch pieces, then blanch briefly in salted boiling water and drain; canned beans should be drained well. Preheat oven to 350°F (or prepare air fryer to the same temperature). Divide fried onions into about 2/3 cup for mixing and 1/3 cup for topping, keeping the topping portion in a small bowl to stay crisp.
- Step 2: In a large bowl, whisk together cream of mushroom soup, milk, and soy sauce until smooth. The soy sauce adds umami without extra saltiness; mix well for even flavor.
- Step 3: Add the prepared green beans, 2/3 cup fried onions, and black pepper to the soup mixture. Gently fold until the green beans are coated and onions are distributed, taking care not to overmix and crush the onions.
- Step 4: Pour the mixture into a 9×9-inch baking dish and spread evenly. Bake for 25 minutes in the oven (or 10 minutes in the air fryer) until bubbly and heated through.
- Step 5: Remove from heat, gently stir to redistribute sauce, then top with the reserved 1/3 cup fried onions. Return to oven and bake 5 more minutes (2 minutes in air fryer) until onions are golden and crispy.
Tips & Variations
- For extra flavor, sauté fresh mushrooms and mix them in before baking.
- Use fresh green beans blanched just until tender-crisp for best texture.
- Swap soy sauce for tamari or coconut aminos for a gluten-free option.
- Try adding a pinch of garlic powder or smoked paprika for a subtle twist.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat covered in the oven at 350°F until warmed through, about 15-20 minutes. Adding fresh fried onions on top before reheating helps retain that crispy texture.

FAQs
Can I use fresh green beans instead of canned or frozen?
Yes, fresh green beans work wonderfully if you blanch them briefly to soften before mixing into the casserole. This helps them cook through evenly during baking.
Can I make this casserole ahead of time?
Absolutely! Prepare the casserole through Step 4, then refrigerate it unbaked. When ready to serve, add the topping onions and bake as directed, adding a few extra minutes if baking from cold.

Ingredients
Green Bean Casserole Ingredients
- 1 can condensed cream of mushroom soup (10.5 oz)
- 1/2 cup milk
- 1 tsp soy sauce
- 4 cups cut green beans (from 2 cans, 1 lb fresh, or one 16 oz frozen package)
- 1/4 tsp ground black pepper
- 1 1/3 cups crispy French fried onions, divided
Instructions
- Prepare Green Beans: If using frozen green beans, thaw completely and drain excess liquid. For fresh beans, trim and cut into 2-inch pieces, then blanch briefly in salted boiling water and drain. If canned, drain well. Preheat oven to 350°F or prepare air fryer to the same temperature. Divide fried onions into two portions: 2/3 cup for mixing into the casserole and 1/3 cup for topping, keeping the topping onions fresh and dry.
- Make Cream Sauce: In a large bowl, whisk together the condensed cream of mushroom soup, milk, and soy sauce until smooth and fully combined. The soy sauce adds depth without excess saltiness, so ensure it is well incorporated.
- Mix Casserole: Add drained green beans, 2/3 cup fried onions, and ground black pepper to the cream sauce. Gently fold to coat green beans evenly without breaking up the fried onions to maintain their texture.
- Bake Initial Layer: Transfer mixture to a 9×9-inch baking dish and spread evenly. Bake in the preheated oven for 25 minutes (or 10 minutes in an air fryer) until bubbling around the edges and heated through.
- Add Topping and Final Bake: Remove casserole and gently stir to redistribute sauce. Evenly sprinkle reserved 1/3 cup fried onions over the top. Return to oven and bake an additional 5 minutes (or 2 minutes in air fryer) until onions are golden brown and casserole is bubbling, creating a creamy interior with a crispy topping.
Notes
- You can use fresh, frozen, or canned green beans depending on availability and preference.
- Blanching fresh green beans helps retain their bright color and texture in the casserole.
- Dividing the fried onions is key for a crispy topping while maintaining crunch within the casserole.
- Soy sauce enhances umami flavor without increasing saltiness significantly.
- The baking time varies if using an air fryer; adjust accordingly for best results.
