Why You’ll Love This Recipe

I love this recipe because it’s fuss-free, flavorful, and a guaranteed crowd-pleaser. It comes together with pantry staples, and I don’t need to be a professional cook to pull it off. The creamy texture pairs so well with the crispy topping, and I like how it adds a warm, nostalgic touch to my table—especially during Thanksgiving or Sunday dinners. Plus, it’s just as good the next day, if not better.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Canned green beans (cut or French-style, drained)
Condensed cream of mushroom soup
Milk
Black pepper
French fried onions

Directions

I preheat the oven to 350°F (175°C).
In a mixing bowl, I stir together the cream of mushroom soup, milk, and black pepper until smooth.
I add the green beans and about two-thirds of the fried onions, then mix everything until evenly coated.
I pour the mixture into a 9×9-inch baking dish and smooth the top.
I bake the casserole for 25 minutes, then take it out and sprinkle the remaining fried onions on top.
I return it to the oven for another 5 minutes, just until the onions are golden and crispy.
I let it sit for a couple of minutes before serving so the sauce thickens slightly.

Servings and Timing

This classic green bean casserole serves about 6 people. It takes roughly 10 minutes to prepare and 30 minutes to bake, making it an easy side dish I can whip up even on busy days.

Variations

When I want to change things up, I sometimes use fresh or frozen green beans instead of canned. Blanching them first keeps them tender-crisp. For added flavor, I mix in sautéed mushrooms, garlic, or shredded cheddar cheese. I’ve even topped it with crushed Ritz crackers for a twist. If I’m cooking for a bigger crowd, I just double the recipe and use a 9×13-inch pan.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. When reheating, I cover it with foil and warm it in the oven at 350°F until heated through—usually 15–20 minutes. If I’m in a rush, the microwave works fine too. I add a few fresh fried onions on top if I have extra, just to bring back that crisp texture.

FAQs

Can I make this casserole ahead of time?

Yes, I often prepare the casserole up to the baking stage and store it covered in the fridge. When I’m ready to bake, I add the topping and cook it as directed.

Can I use fresh green beans instead of canned?

Absolutely. I trim and blanch fresh green beans until just tender, then follow the recipe as usual. They add a nice texture and bright flavor.

Is there a dairy-free version of this recipe?

Yes, I use a dairy-free cream of mushroom soup and substitute the milk with a plant-based alternative. It still turns out creamy and delicious.

Can I freeze green bean casserole?

I usually don’t, since the texture can change after thawing. But if I do freeze it, I make sure it’s tightly wrapped and freeze it before baking, then bake straight from frozen with extra time.

What can I use instead of fried onions?

If I’m out of fried onions, I’ve used crushed crackers, seasoned breadcrumbs, or even homemade sautéed onions for a different twist.

Conclusion

Campbell’s Green Bean Casserole is one of those dishes I never get tired of making. It’s quick, comforting, and full of familiar flavors that bring people together. Whether it’s part of a big holiday spread or just a cozy side for dinner, this classic recipe delivers every time. I always keep the ingredients on hand because I know I’ll be making it again soon.
