Step-by-Step Instructions
Making Campbell’s Green Bean Casserole is as simple as combining a few ingredients and baking. Here’s how to make it:
- Prepare the Beans:
If using fresh green beans, wash, trim, and blanch them in boiling water for about 2 minutes. Drain and set aside. If you’re using canned green beans, just drain them. Frozen beans don’t need to be thawed. - Make the Sauce:
In a bowl, combine the cream of mushroom soup and milk. Stir until smooth, making sure to remove any lumps. Then, add the soy sauce and stir to combine. - Combine Ingredients:
Add the green beans and half of the French fried onions to the soup mixture. Season with black pepper to taste and stir everything together until well coated. - Bake in the Oven:
Preheat your oven to 350°F (175°C). Spray a 9×9-inch casserole dish with non-stick cooking spray. Pour the green bean mixture into the dish and spread it out evenly. Bake for 25 minutes. - Add the Topping:
After 25 minutes, stir the casserole and sprinkle the remaining French fried onions on top. Return it to the oven and bake for an additional 5 minutes, until the onions are golden brown and crispy. - Air Fryer Option:
For a quicker option, preheat your air fryer to 350°F (175°C). Place the casserole dish into the air fryer and bake for 10 minutes. Stir the casserole, then sprinkle the remaining onions on top and air fry for an additional 2-3 minutes until the onions are crispy and golden.

Tips & Tricks
To ensure your Campbells Green Bean Casserole turns out perfectly every time, keep these tips in mind:
- Check for Doneness: If you’re baking multiple dishes at once, check the casserole’s center for heat. It may need extra time depending on your oven.
- Make Ahead: You can prepare the casserole in advance and store it in the fridge. When you’re ready to bake, allow for a few extra minutes of cooking time if it’s cold from the refrigerator.
- Storage: Leftover casserole can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven or air fryer for best results.
Pairing Ideas and Variations
Campbell’s Green Bean Casserole pairs wonderfully with a variety of Thanksgiving dishes, such as turkey, mashed potatoes, or cornbread stuffing. Here are a few ideas to mix things up:
- Add Bacon: Crumble some cooked bacon and sprinkle it over the top of the casserole before baking for a smoky flavor.
- Cheese Lovers: Mix in shredded cheddar cheese with the green beans for a cheesy twist.
- Nutty Topping: For a different texture, swap the French fried onions for slivered almonds or crushed pecans.
