Ingredients for campbell's canned green bean casserole
Campbell's soup, creamy mushrooms, and crispy onions—this nostalgic holiday classic meets modern comfort food perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz each, undiluted |
| Canned Green Beans 🌱 | 2 cans | 14.5 oz each, drained |
| Cream Cheese 🧀 | 8 oz | Full-fat, cubed for melting |
| White Onions 🧅 | 1 ½ cups | Finely chopped, yellow or white |
| Fresh White Mushrooms 🍄 | 1 lb | Sliced, cremini or button |
| Corn Flakes 🍞 | 1 ½ cups | Crushed into fine crumbs |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Milk 🥛 | ½ cup | Whole for creaminess |
| All-Purpose Flour 🌾 | ¼ cup | For thickening |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For depth of flavor |
| Dried Parsley 🌿 | 1 tsp | For garnish |
The Campbell's cream of mushroom soup is the foundation—10.5 oz cans ensure the right consistency without thinning. For the onions, yellow or white work best, finely chopped for even cooking. Fresh mushrooms add depth, but if using canned, drain well and pat dry. The cream cheese should be full-fat for optimal creaminess; Philadelphia brand is a reliable choice. Corn flakes from Kellogg's crush more uniformly than store brands, creating a superior crispy topping. Purchase the 10.5 oz cans of Campbell's specifically for this recipe—they're formulated for baking applications.
No Campbell's cream of mushroom soup? Condensed cream of celery soup plus 1 tbsp mushroom powder mimics the flavor profile. Substitute cream of chicken soup with 2 tbsp cream cheese for a lighter option. Fresh mushrooms unavailable? Canned mushrooms, drained and chopped work in a pinch. For the cornflake topping, crushed Ritz crackers offer a buttery alternative. The flour is critical for thickening the sauce—Bob's Red Mill all-purpose works best if you're blending your own. Diamond Crystal kosher salt is preferred for its larger crystals that dissolve evenly without altering the recipe's balance.
This casserole reheats beautifully—350°F for 15-20 minutes restores the crispy topping perfectly. Store leftovers in an airtight container for 4-5 days in the fridge. For freezing, portion into individual servings before baking, then freeze baked portions for up to 3 months. The fried onion topping loses crispiness when reheated, so always bake fresh portions for optimal texture. Garnish with fresh parsley before serving to elevate presentation.

Step-by-step instructions for Campbell's canned green bean casserole
A perfect balance of creamy mushroom sauce and crispy corn flake topping awaits—just follow these precise steps.
Sauté the Onions and Mushrooms
In a large skillet over medium heat, melt the 0.5 cup butter until it foams. Add the 1.5 cups finely chopped white onions and cook for 5 minutes until they soften and become translucent. This step is critical for building flavor before combining with the soup.
Push the onions to one side of the skillet and add the 1 lb sliced fresh white mushrooms. Cook for 6-8 minutes until they release their moisture and develop a golden-brown color. The mushrooms should be tender but still hold their shape—overcooking will make them rubbery. Season with 0.5 tsp salt, 0.25 tsp black pepper, and 0.5 tsp garlic powder while they cook.
Create the Creamy Sauce Base
In a separate bowl, whisk together the 2 cans Campbell's Cream of Mushroom Soup, 0.5 cup milk, and 0.25 cup all-purpose flour until smooth. This mixture will thicken the sauce beautifully. If the flour clumps, strain it through a fine-mesh sieve to ensure a velvety texture.
Pour the sauce mixture into the skillet with the sautéed mushrooms and onions. Stir well to combine, then reduce the heat to low and let it simmer for 3-4 minutes until slightly thickened. The sauce should coat the back of a spoon—this indicates it's ready for the next step. If it's too thick, whisk in 1-2 tablespoons of water to adjust the consistency.
Combine with Green Beans and Cream Cheese
Drain the 2 cans canned green beans thoroughly and add them to the skillet. Stir gently to coat the beans evenly with the sauce. Reduce the heat to low and let the mixture warm through for 2-3 minutes, ensuring the green beans are heated but not mushy.
Remove the skillet from heat and stir in the 8 oz cubed cream cheese until fully melted and smooth. The cream cheese adds a luxurious richness that balances the tangy mushrooms. Taste and adjust seasoning if needed—this is the moment to ensure the flavors are perfectly harmonized before baking.
Prepare the Crispy Corn Flake Topping
In a food processor or blender, pulse the 1.5 cups corn flakes into fine crumbs. This texture is essential for achieving that signature crispy topping. Transfer the crumbs to a bowl and stir in 1 tsp dried parsley for a pop of color and freshness.
Spread the green bean mixture evenly into a 9x13-inch baking dish, smoothing the top with a spatula. Sprinkle the corn flake crumbs evenly over the top, pressing down gently to ensure they adhere. This step guarantees the crunchy texture you crave.
Bake to Golden Perfection
Preheat your oven to 375°F and place the baking dish on the middle rack. Bake for 20-25 minutes until the top is deep golden brown and the edges are bubbling. The corn flake topping should be crispy enough to hold its shape when you lift a corner.
Let the casserole rest for 5 minutes before serving—this allows the layers to set and makes slicing cleaner. The result should be a creamy, mushroom-infused green bean filling with a perfectly crispy, golden-brown topping that adds texture contrast with every bite.
Pro Tips For Making Campbell'S Canned Green Bean Casserole
- Preheat Your Mushrooms: Sauté the onions and mushrooms in a dry skillet for 5–7 minutes before adding them to the soup. The extra caramelization deepens the flavor—no oil needed, just let them get golden and slightly crispy. I used to skip this, and the dish always tasted flat.
- Drain, Rinse, Repeat: Drain the canned green beans, then rinse them under cold water and drain again. This removes excess starch and salt, which keeps the casserole from turning gluey. Trust me, your future self will notice the difference.
- Whisk the Cream Cheese: Cut the cream cheese into small cubes and whisk it directly into the warm soup mixture, not the cold one. This prevents clumping and ensures a smooth, creamy texture. I learned this after scraping lumps out of three batches.
- Top with Cold Cheese: Use cold cream cheese (straight from the fridge) for the topping, and sprinkle it just before baking. It melts evenly without turning greasy or sliding off the beans. Yes, it’s counterintuitive, but it works every time.
Perfect pairings for this dish
Classic Holiday Pairings
This casserole shines alongside roasted turkey or ham for Thanksgiving and Christmas feasts. The creamy mushroom flavor complements the savory richness of turkey perfectly, while the crispy topping adds a delightful contrast. I always serve it with garlic mashed potatoes—the buttery smoothness balances the tangy casserole beautifully. 🍽️
Protein-Packed Additions
For a heartier meal, stir ½ cup cooked diced ham or crumbled bacon into the green bean mixture before baking. The smoky bacon adds depth, while ham brings a salty sweetness that pairs wonderfully with the mushrooms.
For vegetarians, top with ¼ cup shredded cheddar cheese during the final 5 minutes of baking for a melty finish.
Beverage Pairings
A glass of chilled sparkling white wine like Prosecco or Moscato cuts through the richness beautifully. For non-alcoholic options, iced hibiscus tea with a splash of lemon provides a refreshing contrast.
I also love serving it with hot apple cider during the holidays—the warm spices complement the casserole's creamy texture perfectly.
Modern Twist Pairings
For a contemporary touch, serve alongside roasted Brussels sprouts with balsamic glaze—their caramelized edges contrast the casserole's creaminess. Another great pairing is crusty sourdough bread with a side of whipped honey butter for dipping. The bread soaks up any extra sauce, making it feel like a complete meal in itself.
Dessert Complements
End your meal with pumpkin pie or pecan pie—the warm spices in these desserts echo the earthy mushrooms in the casserole. For a lighter option, vanilla ice cream with a drizzle of caramel sauce provides a sweet contrast.
The creamy texture of the ice cream balances the savory flavors beautifully. 🍰
Year-Round Versatility
This casserole isn’t just for holidays! Serve it as a weeknight dinner with grilled chicken or steak for a cozy meal. For a lighter lunch, pair it with a simple arugula salad dressed in lemon vinaigrette.
The peppery greens refresh your palate after the rich casserole. The versatility makes it a pantry staple year-round. ✨

Frequently asked questions
Can I make this casserole ahead of time?
Prepare the green bean mixture and assemble the dish up to 24 hours ahead, but hold off on baking. Cover tightly with foil and refrigerate. When ready to bake, increase the oven time by 5-7 minutes to account for the cold start. The topping will still achieve that perfect crispiness.
Why is my cornflake topping soggy?
Soggy topping happens when moisture escapes during baking. To fix this, press the cornflake crumbs firmly onto the casserole before baking. For extra insurance, sprinkle a thin layer of shredded parmesan cheese between the green bean layer and topping—it creates a moisture barrier. Also ensure your oven rack is in the middle position for even heat distribution.
Can I use frozen green beans instead of canned?
Yes, but you'll need to thaw and drain them thoroughly first. Use 1.5 lbs frozen green beans (about 3 cups packed) instead of two cans. Spread them on a paper towel to remove excess moisture before mixing with the sauce. Frozen beans work best when cooked slightly longer—simmer for 4-5 minutes to ensure they're tender.
What's the secret to extra creamy texture?
The magic lies in the cream cheese-to-soup ratio and proper melting technique. Always use full-fat cream cheese and cut it into small cubes to melt smoothly. For extra richness, whisk in 2 tablespoons sour cream with the cream cheese. Chill the mixture for 10 minutes before baking to prevent excessive spreading. The result? Ultra-smooth, velvety perfection.
How do I reheat leftovers without losing crispiness?
Reheat covered with foil at 350°F for 15 minutes, then uncover and broil for 2-3 minutes to restore the crunch. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals, stirring between each. The key is minimal time at high heat to maintain texture. For best results, always bake fresh portions when possible.
