Ingredients for original campbell soup green bean casserole
Classic comfort in one skillet—just 11 ingredients for that nostalgic creamy crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 1 ½ lb | Trimmed, cut into 2-inch pieces |
| Yellow Onions 🧅 | 1 whole | Thinly sliced for frying |
| Mushroom Soup 🍄 | 2 cans | 10.5 oz each, condensed style |
| Heavy Cream 🥛 | ½ cup | Full-fat for creamy texture |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For added depth of flavor |
| Butter 🧈 | 2 tbsp | Unsalted, for frying onions |
| French Fried Onions 🧅 | 1 cup | For extra crunch (optional) |
| Milk 🥛 | ¼ cup | For adjusting sauce consistency |
The yellow onions are key for that signature crunch. Sweet Vidalia onions work best, but any yellow variety will do. For the mushroom soup, Campbell's Condensed Cream of Mushroom is the original choice—it's pre-seasoned perfectly. The green beans should be fresh but not overly crisp; slightly tender beans hold up better in baking. If using frozen, thaw and drain completely before cooking. Costco or Trader Joe's often carry pre-trimmed green beans, saving you prep time.
No heavy cream? Half-and-half or whole milk works in a pinch, though the sauce won't be quite as rich. The French fried onions are optional but worth it—they add that extra crunch. Gluten-free onion rings (like those from Trader Joe's) make this gluten-free friendly. For a lighter version, swap the heavy cream for evaporated skim milk. The garlic powder can be replaced with 1/4 tsp fresh minced garlic if you prefer. Just remember, the original recipe relies on that creamy, velvety texture, so don't skip the full-fat dairy.
This casserole reheats beautifully—just cover with foil and bake at 350°F for 15 minutes. It keeps well in the fridge for 4-5 days, though the topping may soften slightly. For extra crispiness, broil for 2 minutes before serving. Portion into individual ramekins ahead of time for easy reheating. The onions stay crispest when added right before baking, so plan accordingly if prepping ahead. Freezes for 3 months if stored in an airtight container.
Why You'll Love This Recipe
- Let’s be real: green beans and onions are cheap, and a can of soup stretches this into plenty of servings. The leftovers reheat like a dream—just add a splash of milk to the creamy topping, and it’s just as good the second day. I’ll take a reliable, wallet-friendly meal any day over takeout.
- One-Pot Magic: I swear by this recipe because it’s literally one pan—no fussing with multiple dishes. Toss the green beans, onions, and soup in one baking dish, top with the creamy mushroom mixture, and boom. Done. My counters stay clean, and honestly? That’s half the battle on a weeknight.
- Creamy Crunch Harmony: Between us, the texture is chef’s kiss—crispy fried onions on top, silky mushroom cream underneath, and those bright green beans cutting through it all. The Campbell’s soup brings that savory depth, while the heavy cream and flour roux make it rich without tasting heavy. It’s the kind of dish where every bite feels balanced.
- Game for Any Gathering: This isn’t just a holiday side—it’s my go-to for potlucks, tailgates, or even a lazy Sunday supper. Double the recipe, and it feeds a crowd without needing a second guess. (Yes, even on a Tuesday night.) My college-aged son still asks for it when he comes home, and that’s saying something.
Step-by-step instructions for original Campbell soup green bean casserole recipe
This classic recipe delivers the perfect balance of creamy mushroom sauce and crispy fried onions in one skillet.
Prep and Parboil the Green Beans
Trim the ends from the 1.5 lb fresh green beans and cut them into 2-inch pieces. Bring a large pot of salted water to a boil and cook the green beans for 3-4 minutes until they're bright green and slightly tender but still crisp. Drain immediately and set aside.
Don't overcook the beans—they'll finish cooking in the oven. You want them to hold their shape but soften enough to absorb the creamy sauce. If you're short on time, you can skip this step and add the raw beans directly to the skillet, but they'll take longer to cook through.
Sauté the Onions and Make the Sauce Base
In the same skillet you'll use for baking, melt the 2 tbsp butter over medium heat. Add the thinly sliced 1 whole yellow onion and cook for 5-6 minutes until softened and golden brown. This step builds flavor that will carry through the entire dish.
Sprinkle the 2 tbsp all-purpose flour over the onions and stir for 1-2 minutes until the mixture turns a light golden color. Slowly pour in the 2 cans mushroom soup and the 0.5 cup heavy cream, stirring constantly to create a smooth sauce. Season with the 1 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder.
Combine and Bake the Casserole
Return the drained green beans to the skillet and stir gently to coat them evenly with the sauce. Transfer the entire mixture to a preheated 350°F oven and bake uncovered for 25-30 minutes until the sauce thickens and the beans are tender.
Here's the secret to creamy perfection: if the sauce looks too thick before baking, stir in the 0.25 cup milk to reach your desired consistency. You want a sauce that coats the beans but isn't watery. The casserole is done when the edges are bubbly and the beans are fork-tender.
Top with Crunchy Fried Onions and Bake Again
Remove the casserole from the oven and sprinkle the 1 cup French fried onions evenly over the top. Return to the oven for 3-5 minutes just to heat through the topping and get it crispy again.
This second baking ensures the fried onions stay crunchy rather than soggy. Serve immediately while the onions are still crisp and the sauce is hot. The contrast between the creamy sauce and crispy topping is what makes this classic casserole so satisfying.
Pro Tips For Making Original Campbell Soup Green Bean Casserole
- Trim and Blanch Beans: Cut the ends off your green beans—yes, even the thick ones—then blanch them for 3 minutes in boiling water. This keeps them crisp-tender instead of turning mushy when baked later. I used to skip this and ended up with sad, soggy beans every time.
- Sauté Onions Until Sweet: Cook those yellow onions in butter until they’re golden and caramelized, not just soft. The deeper flavor carries through the whole dish, and it balances the creaminess of the soup. I learned this the hard way by rushing and getting a bland base.
- Whisk Cream Cold: Chill your heavy cream before mixing it into the mushroom soup—it prevents the roux from breaking and turning grainy. I once used warm cream and spent 10 minutes fixing a lumpy mess. Cold cream = smooth sauce every time.
- Bake Until Top Bubbles: Don’t pull the casserole out when it looks "done"—wait until the top is bubbling and the edges are golden. The last 5 minutes of baking make the difference between a good dish and a great one. (Yes, even if you’re impatient like me.)
Serving suggestions for original campbell soup green bean casserole
Classic Holiday Pairings
This casserole is the ultimate side dish for Thanksgiving and Christmas dinners. Its creamy texture and nostalgic flavor pair perfectly with roasted turkey or ham. I like to serve it alongside garlic mashed potatoes and cornbread for a Southern-style feast.
The rich mushroom sauce balances the savory meats beautifully, while the crispy onions add a delightful crunch. 🍽️
Protein Pairings
Turn this dish into a main course by serving it with grilled or roasted chicken breast or steak. The creamy beans complement the protein wonderfully. For a vegetarian option, pair it with garlic roasted Brussels sprouts or a spinach salad with balsamic dressing.
The contrast of textures and flavors makes every bite satisfying.
Bread and Crusts
Warm, crusty bread is essential for soaking up all that creamy sauce. I recommend serving with sourdough or Italian bread. For extra indulgence, add a side of buttery dinner rolls or cornbread muffins.
The bread helps balance the richness of the casserole and makes it feel like a true comfort meal.
Cheese and Garnishes
Add a final touch with shredded sharp cheddar cheese or Parmesan right before serving. The cheese melts slightly and adds a savory depth. Fresh parsley or chives sprinkled on top provide a bright, fresh contrast to the creamy sauce.
For extra flair, drizzle with a little hot honey for a sweet-spicy finish. 🌟
Leftovers Reinvented
Transform leftovers into a delicious green bean casserole grilled cheese. Use slices of sourdough or white bread with a layer of the casserole in between. Grill until golden and crispy for a fun twist.
You can also turn it into a creamy green bean soup by adding broth and simmering until smooth. These reinventions keep the dish exciting even after the holiday meal.
Seasonal Twists
For spring or summer gatherings, add fresh dill or basil to the sauce for a brighter flavor. In fall, swap the French fried onions for crispy bacon bits or toasted pecans for a festive touch.
These seasonal variations keep the classic dish feeling fresh and modern while staying true to its comforting roots. 🍂

Frequently asked questions
Why does my green bean casserole sauce get watery after baking?
The sauce may thin out if the green beans release too much moisture during baking. To fix this, parboil the beans for just 3-4 minutes (not longer) and drain them well before mixing with the sauce. If the sauce still seems thin, stir in an extra 1 tbsp flour or 1 tbsp cornstarch mixed with 1 tbsp cold water before baking.
Can I make this casserole ahead of time?
Yes! Assemble the casserole (without the fried onion topping) up to 24 hours ahead and refrigerate. When ready to bake, add the onions and bake as directed. For extra crispiness, broil for 2 minutes before serving. The onions should always go on fresh to stay crunchy.
What’s the best way to make the fried onion topping crispy?
Fry the onions in batches over medium heat until golden brown (about 3-4 minutes per batch). Let them cool completely before sprinkling on the casserole. For maximum crunch, add the onions right before the final 3-5 minutes of baking. Avoid using damp onions—they’ll steam instead of crisp.
Can I substitute cream of mushroom soup for another type?
While Campbell’s Condensed Cream of Mushroom is the original, you can swap it for cream of celery soup or homemade mushroom sauce (sautéed mushrooms + broth + cream). For a lighter version, use low-fat cream cheese** blended with milk. Just note the flavor will differ slightly.
How do I reheat leftovers without losing the crunch?
Reheat covered with foil at 350°F for 15 minutes, then uncover and broil for 1-2 minutes to restore crispiness. For microwave reheating, cover with a damp paper towel and heat in 30-second bursts, stirring between each. Add fresh fried onions on top right before serving.
