Ingredients for campbell's canned green bean casserole
Pantry staples transform into nostalgic 1950s comfort with Campbell's iconic cream of mushroom soup as the base.
| Ingredient | Amount | Notes |

| Sharp Cheddar Cheese 🧀 | 1 cup | Shredded, 2-year aged |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |

The Campbell's cream of mushroom soup is the heart of this recipe—grab the condensed version for authentic texture. Walmart or Target always stock it, but if you're feeling nostalgic, check the vintage aisle at World Market for retro cans. The canned green beans should be cut, not whole—Green Giant or Del Monte are reliable brands. For that signature creamy texture, full-fat heavy cream and whole milk are non-negotiable; low-fat versions won't deliver the same velvety finish. The fried onions? Store-bought from the canned aisle saves time, but if you're ambitious, homemade fried onions (sautéed in butter until crispy) add a restaurant-quality touch.
No Campbell's soup? Substitute with 1.5 cups of homemade mushroom cream sauce—sauté mushrooms in butter, add cream and a splash of milk, then season with salt, pepper, and nutmeg. Swapping the cheddar? Gruyère or Monterey Jack work beautifully, but avoid pre-shredded—it gets gummy when baked. The flour is purely for thickening; if you're gluten-free, cornstarch at half the amount does the job. For extra depth, toast the garlic and onion powders in a dry pan for 30 seconds before adding—this brings out their aromatic oils. The nutmeg is subtle but essential; omit it only if you're avoiding dairy entirely.
This casserole reheats beautifully—cover with foil and bake at 350°F for 20 minutes to restore crispiness. Leftovers keep in the fridge for 4-5 days, though I rarely have any. For holiday gatherings, double the recipe and bake in a larger dish—it's always a crowd-pleaser. The fried onions lose crispness over time, so sprinkle fresh ones on top before serving if reheating. Freezes well for up to 3 months; thaw overnight in the fridge before reheating.

Step-by-step instructions for Campbell's canned green bean casserole
Here's how to recreate that nostalgic, creamy texture with modern techniques and precise measurements.
Prepare the Creamy Base
In a medium saucepan, melt the 0.5 cup butter over medium heat. Once fully melted, whisk in the 2 tbsp all-purpose flour and cook for 1-2 minutes until the mixture turns a light golden color. This creates a roux that will thicken our sauce beautifully.
Gradually whisk in the 2 cans Campbell's Cream of Mushroom Soup, stirring constantly to prevent lumps. Add the 0.5 cup heavy cream, 0.5 cup milk, 1 tsp garlic powder, 1 tsp onion powder, 0.5 tsp salt, 0.25 tsp black pepper, and 0.25 tsp ground nutmeg. Bring the mixture to a gentle simmer and cook for 5-7 minutes, stirring occasionally, until it thickens to a creamy consistency that coats the back of a spoon.
Incorporate the Green Beans
Drain the 2 cans canned green beans thoroughly, reserving ½ cup of the liquid in case you need to thin the sauce later. Add the green beans to the saucepan and stir gently to coat them evenly in the creamy mixture. Let the entire casserole sit at room temperature for 5 minutes to allow the flavors to meld together.
Here's where the magic happens: the green beans will absorb some of the sauce, creating that perfect balance of creamy and slightly textured bite. If the mixture appears too thick, add 1-2 tablespoons of the reserved green bean liquid to reach your desired consistency. The sauce should be thick enough to coat the back of a spoon but still flow smoothly.
Assemble and Bake
Preheat your oven to 350°F. In a 9x13-inch baking dish, spread the green bean mixture evenly, creating a smooth surface. Sprinkle the 1 cup sharp cheddar cheese evenly over the top, pressing down gently to help it melt into the casserole. This step ensures every bite has that rich, cheesy flavor we all love.
Next, scatter the 1 cup fried onions evenly over the cheese layer. The onions will provide that satisfying crunch that makes this casserole so beloved. Transfer the baking dish to the preheated oven and bake for 25-30 minutes, until the top is golden brown and bubbly, and the edges are slightly crispy.
Rest and Serve
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice and serve. The creamy sauce will have thickened further, creating that perfect 1950s-style texture we're after.
Serve warm, straight from the baking dish. The combination of creamy sauce, tender green beans, crispy fried onions, and melted cheese creates a harmonious balance of textures and flavors. For best results, serve immediately while the top is still slightly crispy and the cheese is melted throughout.
Pro Tips For Making Campbell'S Canned Green Bean Casserole
- Drain and Rinse Beans: The canned green beans come packed in saltwater—skip the rinse and you’ll end up with a watery, diluted sauce. Drain them well, then give them a quick cold-water rinse to cut excess salt, especially if you’re using low-sodium soup. This keeps the creaminess sharp and the texture just right.
- Simmer the Soup First: Mixing the cold soup directly with the cream and milk often leads to a grainy, lumpy mess. Heat the soup alone for 2–3 minutes until it’s steaming, then stir in the cream and milk off the heat. This guarantees a smooth sauce every time—no clumping, no stress.
- Toast the Onions: Those fried onions? They’re the star, so don’t just dump them on top like an afterthought. Toss them in a dry skillet for 30 seconds until they’re golden and slightly crisp—this adds a nutty depth that turns a basic topping into a flavor bomb. (Yes, even if you’re in a hurry.)
- Skip the Overmixing: Once you fold in the beans, stir just enough to coat them—overmixing turns the casserole into a mushy, soupy disappointment. A few gentle folds are all it takes. If it looks uneven, that’s fine; the oven will even it out. Less stirring = better texture.
Storing and reheating your campbell's canned green bean casserole
Refrigerator Storage
After baking, let your casserole cool for 30 minutes before transferring to an airtight container—I use glass Pyrex with a tight-fitting lid to maintain freshness. Store in the fridge at 40°F or below for up to 4-5 days.
The flavors actually deepen over time, making it perfect for meal prep. Just remember to sprinkle fresh fried onions on top before reheating to restore that crispy crunch. 🧅
Freezer Prep Tips
For long-term storage, freeze individual portions in quart-sized freezer bags or glass containers with 1-inch headspace to prevent expansion cracks. Label with the date—this casserole stays delicious for up to 3 months.
I recommend freezing before adding the fried onions, then topping with fresh ones after reheating for maximum crispness. 💫
Oven Reheating Method
For the best texture, cover the casserole with aluminum foil and bake at 350°F for 20-25 minutes. Remove the foil for the last 5 minutes to restore that golden-brown top.
This method prevents drying out while reactivating the crispy onion layer. Stir gently before serving to redistribute any settled sauce. 🔥
Microwave Revival
For quick reheating, transfer a portion to a microwave-safe dish and cover with a damp paper towel. Heat on 50% power for 2-3 minutes, stir, then continue in 30-second intervals until reaching 165°F.
Add 1-2 tablespoons of milk or water if the casserole looks dry. The onions will lose some crispness, so consider adding fresh ones on top after reheating. ⚡
Make-Ahead Holiday Hack
Double the recipe and assemble it in a 9x13-inch baking dish, then refrigerate overnight before baking. This lets the flavors meld perfectly for holiday gatherings. For serving, bake as directed, then cover with foil and keep warm in a 200°F oven until ready to serve.
This ensures a crowd-pleasing centerpiece that stays hot and creamy. 💡
Crispy Top Rescue
If your reheated casserole loses its crispy top, broil for 1-2 minutes on high with a sprinkle of extra cheese. For extra crunch, top with homemade fried onions** (sauté onion slices in butter until golden) right before serving. This simple trick transforms reheated leftovers into something restaurant-worthy. 🌟
Nutrition facts
Frequently asked questions about green bean casserole
Can I make this casserole without canned green beans?
Fresh green beans work beautifully—just trim the ends and blanch them for 3-4 minutes until tender-crisp. Drain well and use 3 cups total (about 1.5 pounds fresh beans). For extra richness, add ½ cup sautéed mushrooms to the sauce base to compensate for the reduced canned bean liquid.
What's the secret to perfectly crispy fried onions?
Use store-bought fried onions from the canned aisle (like French's) for convenience—they're pre-cooked to crispness. For homemade, thinly slice onions and fry in ¼ cup butter over medium-high heat for 8-10 minutes until golden. Spread them on parchment paper to cool—they crisp up as they cool!
Can I make this dish dairy-free?
Yes! Replace the cheese with ½ cup nutritional yeast for a cheesy flavor, and use coconut milk instead of dairy milk. For the creamy base, blend ½ cup cashews with ½ cup water until smooth, then stir into the soup mixture. The texture will be lighter but still satisfying.
Why did my casserole turn out watery?
Watery results usually happen when the sauce isn't thickened enough before baking. Always cook the roux (butter + flour) until golden, and simmer the sauce for the full 5-7 minutes. If using fresh green beans, drain them thoroughly and reserve only 1-2 tbsp of liquid—too much liquid dilutes the sauce.
Can I bake this in a smaller dish?
Yes, but adjust the baking time. For a 8x8-inch dish, bake for 20-25 minutes (cover with foil if browning too fast). For a 9x9-inch dish, use 25-30 minutes. The key is to ensure the center reaches 165°F. Smaller dishes may need 5-10 extra minutes to fully heat through.
