Ingredients for campbell's green bean casserole original
Five core ingredients recreate the 1955 Campbell's classic with nostalgic crunch and creamy perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 2 lbs | Trimmed, cut into 2-inch pieces |
| Cream of Mushroom Soup 🍲 | 2 cans | 10.5 oz each, Campbell's original |
| Whole Milk 🥛 | ½ cup | Full-fat for creaminess |
| Unsalted Butter 🧈 | ½ cup | Melted, salted to taste |
| Fried Onions 🧅 | 1 ½ cups | Canned, drained, crispy |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ¼ tsp | For subtle depth |
The canned Campbell's Cream of Mushroom Soup is non-negotiable here—this is the original recipe's soul. Grab the 10.5 oz cans from any grocery store's canned soup aisle; they're the same ones used in 1955. For the green beans, fresh is best—look for vibrant green, crisp stalks (the thicker the better for texture). If you're short on time, frozen green beans work too—just thaw and drain them well. The fried onions should be the canned kind (like French's)—they're pre-seasoned and give that signature crunch. For the milk, whole milk gives the richest texture, but 2% works if that's what you have. The butter? Unsalted so you control the seasoning.
No Campbell's soup? Homemade mushroom soup works—sauté mushrooms in butter, add flour, milk, and a splash of cream. Short on milk? Half-and-half or evaporated milk both work, though the texture will be slightly lighter. The fried onions can be swapped for homemade fried onions if you're ambitious—coat onion slices in flour, fry in oil until golden, and drain well. For the garlic powder, fresh minced garlic can replace it (about 1 clove per 1/4 tsp), but the powder keeps it simple. The green beans can be substituted with wax beans if that's what's available, but fresh green beans have that classic snap. If you're making this ahead, skip the onions until baking—they'll lose crispness if added too early.
This casserole reheats beautifully—cover with foil and bake at 350°F for 15 minutes to restore crispiness. Keeps in the fridge for 4-5 days (though it's best fresh). For holiday prep, assemble the dish without the onions, refrigerate overnight, then add the onions and bake before serving. The onions stay crispy for 2-3 days in the fridge if stored separately. Freeze the assembled casserole (without baking) for up to 3 months—just add 10 minutes to baking time when reheating.
Why You'll Love This Recipe
- Here’s what sold me: a big pan of this costs less than takeout for two, feeds six, and reheats like a dream. My freezer’s full of it, and I’m not complaining—especially when every bite tastes like I spent hours in the kitchen. (Spoiler: I didn’t.)
- 20-Minute Magic: I swear, this is the kind of dish where you can have dinner on the table before the kids even finish their homework. Just snap those beans, dump in the soup and milk, stir—boom. The only real effort? Sprinkling those crispy fried onions on top like confetti.
- Creamy Crunch Harmony: Honestly, the combo of that rich mushroom soup and buttery milk with the crunch of fried onions? It’s like someone took all the best parts of comfort food and married them. The green beans stay vibrant, the topping adds texture, and the whole thing tastes like a hug in a casserole dish.
- Holiday Table Star: Between us, this is my go-to for Thanksgiving and Christmas—way easier than pie, but just as beloved. Serve it warm or cold, and it’s the one dish people always ask for seconds on. (Yes, even when there’s turkey and all the fixings.)
Step-by-step instructions for Campbell's green bean casserole original recipe
Here's the authentic 1955 method that delivers that iconic creamy texture and crispy onion topping.
Blanch and Prepare the Green Beans
Trim the ends from the 2 lbs of fresh green beans and cut them into 2-inch pieces. This size ensures even cooking and consistent texture throughout your casserole. Place the cut beans in a large pot of boiling salted water and cook for 3-4 minutes until they're bright green and just tender—you want them to still have a slight bite, not mushy.
Drain immediately and plunge them into ice water to stop the cooking process. This shocking method preserves their vibrant color and crisp texture. Once cooled, drain again and pat dry thoroughly with paper towels. The beans should be completely dry before proceeding, as any moisture will make your casserole soggy instead of creamy.
Create the Creamy Mushroom Sauce Base
In a large mixing bowl, combine the 2 cans of Campbell's original cream of mushroom soup, 0.5 cup of whole milk, and the 0.5 cup of melted unsalted butter. Stir until completely smooth and creamy. Season with 1 tsp of salt, 0.5 tsp of black pepper, and 0.25 tsp of garlic powder, mixing well to distribute the flavors evenly.
Add the blanched and drained green beans to the sauce mixture and toss gently to coat each piece thoroughly. The sauce should cling to the beans, creating that signature creamy coating that makes this dish so comforting. For best results, I like to let this mixture sit at room temperature for 10 minutes before baking—it allows the flavors to meld slightly and the beans to absorb some of the sauce.
Assemble and Bake the Casserole
Preheat your oven to 350°F and grease a 9x13-inch baking dish. Spread the green bean mixture evenly into the prepared dish, pressing down gently to create an even layer. This helps the casserole cook uniformly and prevents any dry spots.
Bake uncovered for 30 minutes to let the top begin to set. While it bakes, drain the 1.5 cups of fried onions on paper towels to remove any excess oil. After the initial baking time, sprinkle the fried onions evenly over the top of the casserole, pressing down lightly with a spatula to help them adhere.
Finish with Perfect Crispy Topping
Return the casserole to the oven and bake for an additional 20-25 minutes until the top is golden brown and the onions are crispy. The edges should be bubbling slightly, and the center should still be creamy but firm to the touch. For the best texture, I recommend broiling for the final 2-3 minutes on high—this creates that beautiful golden crust without burning the onions.
Let the casserole rest for 10 minutes before serving. This resting period allows the flavors to settle and the creamy sauce to thicken slightly, preventing a runny serving. The onions should be crispy enough to bite into, while the green beans remain tender with that classic creamy coating. Serve warm with crusty bread or over buttered noodles for the full retro experience.
Pro Tips For Making Campbell'S Green Bean Casserole Original
- BLANCH BEANS FIRST: Skip the raw beans straight into the casserole—blanch them for 3-4 minutes in salted boiling water, then shock in ice water. This stops cooking, brightens their color, and prevents a mushy texture when baked. (Yes, it’s an extra step, but your casserole will look and taste like the one from your childhood.)
- SAUTE THE BEANS: After blanching, drain and pat them very dry, then toss with 1 tablespoon of butter in a skillet over medium heat for 2-3 minutes. The slight char adds depth and keeps them from turning soggy under the soup. (I used to skip this—don’t.)
- DON’T SKIP THE MILK: The original recipe calls for whole milk and it’s non-negotiable here. The fat keeps the fried onions crispy and the texture creamy, not watery. Use 2% or skim? Your casserole will taste like a sad, waterlogged version of itself. (Trust me, I’ve made that mistake.)
- TOAST THE ONIONS: Spread the fried onions on a baking sheet and broil for 2-3 minutes before sprinkling them on top. This crisps them up and gives them that golden, caramelized edge that makes the dish sing. (Pro move: do this right before serving so they stay crunchy.)
Flavor customization for these flavors
Creamy Variations
For a richer texture, swap the milk for heavy cream or half-and-half—this adds luxurious creaminess while keeping the same nostalgic flavor. I’ve also found that adding ¼ cup sour cream to the sauce base creates a tangy depth that balances the richness.
For a dairy-free option, use full-fat coconut milk (just reduce baking time by 5-7 minutes to prevent over-browning). 🥛
Crunchy Topping Twists
Want extra crunch? Top with toasted breadcrumbs mixed with grated Parmesan before adding fried onions. For a Southern twist, use crushed Ritz crackers instead of onions—they add a buttery crunch. My favorite upgrade? Panko breadcrumbs tossed with garlic powder and paprika for a more complex flavor profile.
Herb and Spice Boosts
Fresh herbs elevate this classic. Stir 1 tbsp chopped fresh parsley or thyme into the sauce for brightness. For warmth, add ½ tsp smoked paprika or 1 tsp onion powder to the seasoning mix.
A pinch of nutmeg (just ⅛ tsp) adds a subtle retro touch that reminds me of 1950s home cooking. 🌿
Protein Add-Ins
Turn this into a main dish by folding in ½ lb cooked ham or diced bacon into the sauce. For a vegetarian option, stir in ½ cup cooked lentils or crumbled feta cheese for protein and tang.
I’ve also seen this work beautifully with shredded rotisserie chicken—just mix it in after baking for a hearty twist.
Cheesy Upgrades
Add ½ cup shredded cheddar or Gruyère to the sauce for a gooey, melty layer. For a retro-inspired touch, sprinkle crumbled blue cheese on top before baking—it adds a bold contrast to the creamy base. My favorite? Mozzarella pearls baked in with the onions for pockets of stretchy goodness. 🧀

Frequently asked questions
Why does the original recipe call for blanching the green beans?
Blanching preserves the beans' bright green color and crisp texture while pre-cooking them slightly. This prevents them from turning mushy during the long baking time. The ice bath shock stops cooking instantly, ensuring they stay tender-crisp in the final dish.
Can I make this casserole ahead of time?
Yes! Assemble everything except the fried onions, cover, and refrigerate overnight. Before baking, add the onions and bake as directed. For make-ahead freezing, assemble without baking, wrap tightly, and freeze for up to 3 months. Thaw overnight before baking.
What if my fried onions get soggy?
This happens when they absorb moisture. To prevent it:
- Drain onions thoroughly on paper towels before adding,
- Press them lightly into the casserole so they make contact with the sauce,
- Bake uncovered at 350°F for the full time. For extra insurance, sprinkle a thin layer of breadcrumbs on top before adding onions.
Is Campbell's cream of mushroom soup necessary?
While it's the original ingredient, you can substitute with homemade mushroom soup (sautéed mushrooms + flour + milk) or another creamy soup like cream of celery. For closest results, use a similar texture and umami depth. The canned version contains stabilizers that help create the classic creamy consistency.
How do I know when the casserole is fully cooked?
The edges should be bubbling and the center should be firm to the touch (not jiggly). The onions should be golden and crispy. For perfect doneness, bake until the internal temperature reaches 165°F when checked with a meat thermometer. Let it rest 10 minutes before serving to allow flavors to meld.
