This Campbell's Green Bean Casserole Recipe is creamy, simple, and finished with crispy fried onions. It is the kind of classic side dish that belongs on a holiday table.
Why You'll Love My Campbell's Green Bean Casserole
- You only need a handful of simple ingredients.
- The creamy mushroom sauce coats every green bean perfectly.
- Crispy fried onions add a delicious, crunchy topping.
- It is an easy holiday side dish that can be prepared ahead of time.
I did not grow up with green bean casserole in Spain, so the first time I made it, I understood why it is such a favorite in American homes. It uses simple pantry ingredients, but the result feels comforting and generous. I like serving it with mains like Roast Duck, Baked Pork Loin Chops, or Cast Iron Chicken Breast when I want a full family-style dinner.
What I like most is the contrast. The green beans stay tender, the mushroom sauce makes everything creamy, and the crispy fried onions bring that golden crunch on top. It is easy enough for a family dinner but special enough for Thanksgiving or Christmas, especially with simple sides like Garlic Bread or a fresh Tomato Burrata Salad.
Key Ingredients in Campbell's Green Bean Casserole
You'll find the exact measurements in the recipe card, but here's a closer look at key ingredients and why I use them.
- Green Beans: I use fresh green beans because they stay tender but still keep a nice bite after baking.
- Campbell's Cream of Mushroom Soup & Milk: This combination is what I like for the creamy mushroom sauce because it coats the beans without needing extra steps.
- Salt, Black Pepper & Nutmeg: I keep the seasoning simple, but the small amount of nutmeg adds a warm note that works really well with the mushroom soup.
- French's Crispy Fried Onions: These are what I use for both flavor and texture. Some go into the casserole, and the rest go on top for that golden, crunchy finish.
How to Make Campbell's Green Bean Casserole
You can find the complete printable recipe with measurements below, but for now, here's a quick overview of how it goes:
1. Cook the Green Beans: Boil the green beans in salted water for 8-10 minutes, then drain well.
2. Prepare the Sauce: In a 6x8.5-inch (16x22 cm) baking dish, mix cream of mushroom soup, milk, salt, pepper, and nutmeg until smooth.
3. Combine the Ingredients: Add the beans and toss with ⅔ of the fried onions, coating everything evenly.
4. Bake and Finish: Bake at 350°F / 175°C (325°F convection / 160°C fan) for 20 minutes, top Campbell's Green Bean Casserole with remaining onions, and bake 5 minutes more until golden and crispy.
Tips for the Best Green Bean Casserole
Choose Fresh Green Beans: Fresh green beans give the casserole a better texture and prevent it from becoming too soft after baking.
Watch the Final Bake: The crispy onions can brown quickly, so I keep an eye on them during the last few minutes in the oven.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven until warmed through.
