Ingredients for campbell's green bean casserole original
Six simple ingredients bring back nostalgic comfort food magic with creamy mushroom sauce and crispy onion topping.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 1 ½ lb | Trimmed and cut into 2-inch pieces |
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Fried Onions 🧅 | 1 ½ cups | Store-bought or homemade |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | Not garlic salt |
| All-Purpose Flour 🌾 | ½ tbsp | For thickening sauce |
| Pepperidge Farm French Fried Onions 🧅 | 1 package | For topping, 10 oz |
| Shredded Cheddar Cheese 🧀 | ½ cup | Optional, for extra richness |
The green beans are the star here—fresh is best, but canned works in a pinch. Look for bright green, crisp beans at the store, not limp or yellowing ones. Trader Joe's usually has the best quality, but any grocery store's fresh section will do. If you're using canned, drain them well and rinse with cold water to remove excess sodium. The Campbell's Cream of Mushroom Soup is non-negotiable for that authentic 1955 flavor—don't substitute with other brands. For the fried onions, Pepperidge Farm is the classic choice, but any store-bought fried onions will work if you're in a hurry.
No Campbell's soup? Homemade mushroom sauce works—sauté mushrooms, garlic, and onions, then blend with milk and butter. Short on green beans? Substitute with asparagus or green peas, but adjust cooking time. The milk can be swapped for half-and-half for extra richness, but whole milk gives that classic creamy texture. For the fried onions topping, if you can't find them, quick-pickle sliced red onions in vinegar and sugar for a similar crunch. The cheese is optional but adds a nice tangy kick—sharp cheddar works best.
This casserole reheats beautifully—best the next day when flavors meld. Store leftovers covered in the fridge for 4-5 days or freeze for 3 months. I like to portion it into individual servings before freezing so I can just pop one out for a quick meal. The onions on top get soggy if reheated—always add them fresh after baking. Leftovers taste even better cold, perfect for potlucks or meal prep.

Step-by-step instructions for Campbell's green bean casserole original recipe
Here's how to recreate that nostalgic, creamy crunch from the 1950s—just like grandma used to make.
👨🍳 Step 1: Prep the Green Beans
Start by trimming the ends off the 1.5 lb fresh green beans and cutting them into 2-inch pieces. I like to snap them by hand—it's faster than chopping and gives you more control over the size. Spread the cut beans on a baking sheet and steam them for 5-7 minutes until they're bright green and just tender (they should still have a slight bite).
Here's the thing—overcooking them now will turn them mushy later. You want them to hold their shape but soften enough to absorb the creamy sauce. Drain them well after steaming and set aside. I usually spread them on a clean towel to remove any excess moisture before mixing.
🍳 Step 2: Make the Creamy Sauce
In a large mixing bowl, combine the 2 cans Campbell's Cream of Mushroom Soup, 0.5 cup milk, 0.5 cup melted butter, 0.5 tsp salt, 0.25 tsp black pepper, and 0.5 tsp garlic powder. Stir everything together until it's completely smooth—no lumps allowed. This is the base of your creamy sauce, so take your time here.
Next, sprinkle the 0.5 tbsp all-purpose flour over the mixture and stir again until fully incorporated. The flour will help thicken the sauce later, giving you that perfect consistency. For extra richness, you can stir in the 0.5 cup shredded cheddar cheese now if you like—it'll melt into the sauce beautifully.
🥘 Step 3: Combine and Bake
Transfer the steamed green beans to a greased 9x13-inch baking dish. Pour the creamy sauce mixture over the top and stir gently to coat all the beans evenly. Sprinkle 1.5 cups fried onions evenly over the surface—this is where that classic crunch comes from. Don't skip this step; those onions are the star of the dish!
Bake uncovered at 350°F for 30-35 minutes until the sauce is bubbly and the onions are lightly golden. You'll know it's ready when the edges look set and the top has a slight crust. If you're worried about browning too much, tent the dish with foil for the last 10 minutes of baking.
🔥 Step 4: Add the Topping and Finish
Remove the casserole from the oven and immediately sprinkle the entire package of Pepperidge Farm French Fried Onions evenly over the top. These are the secret to that perfect crunchy texture that everyone loves. Return the dish to the oven for 2-3 minutes just to toast the onions slightly—this gives them that irresistible golden color and crispy bite.
Let the casserole rest for 5 minutes before serving. This resting time lets the flavors meld together and makes it easier to scoop out perfect portions. Serve warm with crusty bread or over buttered noodles for the full retro experience. The creamy mushroom sauce should coat every green bean, and those crispy onions should crunch with every bite!
Pro Tips For Making Campbell'S Green Bean Casserole Original
- STEAM THE BEANS FIRST: Fresh beans need a head start—blanch them in boiling water for 3-4 minutes, then shock in ice water. This softens them just enough to absorb the soup without turning mushy later (yes, even if you’re impatient like me).
- STIR THE SOUP MIX: Combine the Campbell’s soup, milk, and butter in a saucepan and warm it stirring constantly over medium-low heat. Skipping this step means you’ll end up with lumps in your casserole—trust me, you’ll taste them.
- SALT THE BUTTER: Use salted butter (about ½ cup) and add an extra pinch to the soup mix before mixing. The original recipe assumes you’re using unsalted, but most people grab whatever’s in the fridge—and that’s when the flavors fall flat.
- TOAST THE ONIONS: Spread the fried onions on a baking sheet and broil for 2-3 minutes until they’re golden and crisp. This extra step makes all the difference—store-bought onions get soggy fast, and nobody wants a sad, limp topping.

Nutrition facts
Frequently asked questions
Can I make this casserole with canned green beans instead of fresh?
Canned green beans work perfectly—just drain and rinse them well to remove excess sodium. For best texture, choose low-sodium or no-salt-added beans and steam them for 2-3 minutes to warm through before mixing with the sauce. The cooking time in the oven will be the same.
Why does my casserole turn out watery?
Watery results usually happen from oversteaming the beans or not draining them properly. Always steam beans until just tender (5-7 minutes) and drain on a towel to remove excess moisture. Also, ensure you're using the full 0.5 tbsp flour to thicken the sauce—this is key for that perfect creamy consistency.
Can I bake this in a different-sized dish?
Yes, but adjust baking times accordingly. For a 8x8-inch dish, bake for 25-30 minutes instead of 30-35. If using a 9x13-inch dish, the original time works perfectly. For rectangular pans, spread the onions evenly across the top to ensure consistent browning.
How can I make this dish healthier?
Swap the milk for unsweetened almond milk (half-and-half for creaminess), use low-fat cheese or omit it entirely, and bake the onion rings instead of frying them. You can also add 1 cup of steamed broccoli to the mix for extra fiber and nutrients while keeping the classic flavors.
Can I prepare this casserole ahead of time?
This dish tastes even better the next day! Assemble it up to 24 hours ahead and refrigerate uncovered. Bake at 350°F for 40-45 minutes (the extra time accounts for the cold start). For freezing, bake fully, cool completely, then store in an airtight container for up to 3 months—reheat covered at 350°F for 20 minutes.
