Ingredients You’ll Need
Gathering simple, pantry-friendly ingredients is part of the charm of this recipe. Each element plays an essential role, from the fresh green beans adding vibrant color and crunch, to the creamy soup that creates the luscious sauce, and the crispy onions delivering that irresistible finishing touch.
- Green beans (4 cups, fresh, frozen, or canned): The star vegetable that provides a fresh and slightly crisp bite.
- Condensed cream of mushroom soup (1 can, 10.5 oz): The creamy base that brings depth and a rich, savory flavor.
- Milk (½ cup): Smooths out the soup for a velvety texture throughout the casserole.
- Soy sauce (1 tsp): Adds a subtle umami boost that elevates the entire dish.
- Crispy French fried onions (1⅓ cups, divided): The all-important crunchy topping that contrasts beautifully with the creamy beans.
- Black pepper (¼ tsp, or to taste): A touch of spice to balance the flavors without overpowering.
How to Make Campbell’s Green Bean Casserole
Step 1: Prepare Your Green Beans
Start by washing, trimming, and cutting fresh green beans into bite-sized pieces. To ensure they’re perfectly tender but still crisp, blanch them in boiling water for 2 minutes and then drain. If you prefer canned green beans, just drain them well, or thaw frozen ones ahead of time for the best texture.
Step 2: Mix the Creamy Sauce
In a mixing bowl, whisk together the can of condensed cream of mushroom soup, milk, and soy sauce. This combination forms a deliciously smooth and savory sauce that binds the casserole together. Stir in half of the crispy fried onions and add black pepper to taste for a hint of subtle spice.
Step 3: Combine and Arrange
Fold the prepared green beans gently into the soup mixture, ensuring every piece is coated with that creamy goodness. Then, lightly grease a 9×9-inch baking dish with cooking spray and spread the green bean mixture evenly across the bottom.
Step 4: Bake to Perfection
For oven lovers, bake the casserole at 350°F for 25 minutes. After stirring midway, top with the remaining crispy fried onions and put it back in for an additional 5 minutes. If you prefer using an air fryer, bake at the same temperature for 10 minutes, stir, then add the onions and air fry for another 2 minutes until golden and crunchy. This step gives your Campbell’s Green Bean Casserole that signature crispy top that everyone adores.
How to Serve Campbell’s Green Bean Casserole

Garnishes
A sprinkle of fresh parsley or finely chopped chives adds a pop of color and a hint of freshness that pairs beautifully with the creamy casserole. You can also consider a light dusting of grated Parmesan cheese for an extra layer of savory goodness.
Side Dishes
Campbell’s Green Bean Casserole’s creamy and crispy textures complement a variety of dishes wonderfully. It pairs perfectly with roasted turkey, baked ham, or simply a hearty meatloaf. For a vegetarian meal, serve alongside quinoa or rice pilaf for a wholesome and comforting spread.
Creative Ways to Present
Want to dress up this classic? Serve the casserole in individual ramekins for an elegant touch or layer it in clear glass dishes so the yellows, greens, and crispy onions create an enticing visual appeal. Alternatively, try swapping out the traditional onions for spiced pepitas or toasted breadcrumbs to give it a unique twist.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftover Campbell’s Green Bean Casserole to an airtight container and store it in the refrigerator. It will keep well for up to 3 days, making it easy to enjoy those comforting flavors again without any fuss.
Freezing
This casserole freezes beautifully! Portion it out into freezer-safe dishes before baking or freeze the baked casserole after it cools. Either way, wrap tightly and freeze for up to 2 months. Just remember that the crispy onions are best added fresh after reheating to maintain their crunch.
Reheating
Reheat leftovers gently in the oven at 325°F until warmed through, about 15-20 minutes. If reheating from frozen, thaw overnight in the fridge first. Add a few fresh crispy fried onions on top before serving to recapture that delightful bite.
FAQs
Can I use fresh green beans instead of canned or frozen?
Absolutely! Fresh green beans bring a wonderful texture and flavor. Just blanch them briefly before mixing to keep them tender-crisp and vibrant in color.
Is there a way to make this casserole gluten-free?
Yes, you can swap the crispy French fried onions for a gluten-free alternative or use toasted gluten-free breadcrumbs to keep the delicious crunch without the gluten.
Can I make Campbell’s Green Bean Casserole vegan?
To veganize this dish, substitute the cream of mushroom soup with a dairy-free version and choose vegan crispy onions or homemade fried shallots. Use plant-based milk to keep that creamy texture intact.
What’s the best way to prevent the casserole from becoming soggy?
Drain your green beans thoroughly and bake the casserole just until bubbly and the topping is golden. Adding the crispy onions toward the end of baking helps maintain their crunchiness rather than letting them get soggy.
Can I double the recipe for a larger crowd?
Definitely! Just double the ingredients and use a larger baking dish. Increase the baking time slightly and keep an eye on the topping to make sure it crisps up nicely without burning.
Final Thoughts
Campbell’s Green Bean Casserole is one of those true classics that never goes out of style, delivering comfort and joy with every bite. Its creamy sauce, fresh green beans, and crunchy topping come together to create a dish that’s both nostalgic and incredibly easy to make.
