Ingredients for campbell's canned green bean casserole
Just six pantry staples transform into nostalgic 1950s comfort. Creamy, cheesy, and crunchy—this casserole is pure warmth in a dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Green Beans 🍃 | 2 cans | Drained, not rinsed |
| Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz each, Campbell's preferred |
| Whole Milk 🥛 | ½ cup | Full-fat for creaminess |
| Shredded Cheddar Cheese 🧀 | 2 cups | Medium or sharp, freshly shredded |
| French Fried Onions 🧅 | 1 cup | 1.5 oz package, classic brand |
| All-Purpose Flour 🌾 | ¼ cup | For crispy topping |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for topping |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For extra depth |
| Ground Nutmeg 🌿 | ¼ tsp | Optional, for warmth |
The Campbell's cream of mushroom soup is the heart of this dish—grab the classic red can from any grocery store aisle. The green beans? Libby's or Del Monte work perfectly, but any canned green beans will do. For the fried onions, French's Classic is iconic, but any brand with that signature crunch will work. The cheddar matters here—medium or sharp gives the best flavor, and freshly shredded melts smoother than pre-shredded. Pro tip: if you can't find whole milk, 2% works in a pinch, but full-fat gives that authentic 50s richness.
No Campbell's soup? Homemade mushroom sauce with cream and a splash of milk gets you close. Pre-shredded cheese? Grate your own—it melts way better. Out of French fried onions? Crushed potato chips or panko add crunch, though nothing beats the original. The nutmeg is totally optional, but if you've got it, a pinch adds that vintage touch. For a lighter version, swap half the milk for chicken broth—still creamy, just a little less rich. And if you're gluten-sensitive, use gluten-free flour for the topping.
This casserole reheats beautifully—cover with foil and bake at 350°F for 20 minutes. Leftovers keep for 3-4 days in the fridge, but honestly, it's best fresh out of the oven. Freezes for up to 3 months—just thaw overnight in the fridge before reheating. I always make a double batch because it disappears fast. The best part? It's a crowd-pleaser that tastes like home cooking, even if you're just feeding yourself.

Step-by-step instructions for Campbell's canned green bean casserole recipe
This nostalgic classic comes together faster than you'd expect—creamy, cheesy, and topped with that iconic crunch.
Mix the Creamy Green Bean Base
In a large mixing bowl, open both cans of cream of mushroom soup and stir them together until smooth. Add the 0.5 cup whole milk, the 0.5 teaspoon salt, 0.25 teaspoon black pepper, 0.5 teaspoon garlic powder, and 0.25 teaspoon ground nutmeg. Mix until fully combined—this is where all the cozy flavors start melding together.
Next, drain the 2 cans canned green beans (don't rinse them—we want that starchy goodness to help thicken the sauce) and add them to the soup mixture. Gently stir until the beans are evenly coated. The mixture should be thick but still pourable—this is your base, and it's the heart of that comforting texture we all love.
Assemble the Casserole Dish
Preheat your oven to 350°F while you work. Grease a 9x13-inch baking dish lightly with butter or nonstick spray—this ensures the casserole slides out easily when it's time to serve. Pour the green bean mixture into the prepared dish and spread it out evenly with a spatula.
Sprinkle 2 cups shredded cheddar cheese evenly over the top. Press it down gently with the back of a spoon so it melts into the mixture rather than just sitting on top. This step is key—it guarantees that rich, melty cheddiness throughout every bite.
Prepare the Crispy Topping
In a separate bowl, combine 0.25 cup all-purpose flour, 1 cup French fried onions, and the 0.25 cup unsalted butter (cut into small cubes). Use your fingers to work the butter into the flour until it resembles coarse crumbs. The mixture should look like wet sand—this is what creates that perfect crispy topping we all crave.
Sprinkle this topping evenly over the cheese layer in the baking dish. Press down lightly again so it sticks and doesn't shift while baking. The topping should cover the entire surface—this is where the magic happens, giving you that satisfying crunch with every bite.
Bake to Golden Perfection
Place the casserole in the preheated 350°F oven and bake for 35-40 minutes. You'll know it's ready when the top is deep golden brown and bubbly, with the cheese melted completely into the green bean mixture. The French fried onions should be crispy and slightly toasted.
For the best results, let the casserole rest for 10 minutes after baking. This allows the cheese to set slightly and makes it easier to serve without a runny mess. The aroma alone will have everyone gathering around the table—this is pure comfort food at its finest.
Pro Tips For Making Campbell'S Canned Green Bean Casserole
- DRAIN BEANS COLD: The canned green beans come packed with liquid that’ll water down your sauce if you don’t handle it right. Dump them into a colander and run cold water over them for 30 seconds—this stops the cooking process and keeps the texture crisp. I learned this the hard way when my first batch turned into a mushy soup.
- SAUTE THE ONIONS FIRST: Skip the canned onions and toast ¼ cup of finely chopped yellow onion in butter for 3 minutes before mixing everything. The caramelized flavor cuts through the creaminess of the soup and adds depth. It’s an extra 3 minutes of work, but it makes a real difference—especially if you’re serving this to people who’ve had the plain canned version.
- LOW AND SLOW: This isn’t a 350°F casserole. Bake it at 325°F for 20-25 minutes, uncovered, so the top browns without burning. I used to blast it at 375°F and ended up with a sad, uneven crust. The lower temp lets the cheese melt smoothly while keeping the beans tender.
- SALT THE MILK: The cream of mushroom soup is already salty, and whole milk tastes bland on its own. Mix in ¼ teaspoon of salt with the milk before stirring it into the soup—it balances the flavors better than adding it later. Trust me, your taste buds will notice the difference.
Wine and beer pairings for this dish
Creamy White Wine
The rich, cheesy nature of this casserole pairs beautifully with a crisp, dry white wine like Chardonnay or Sauvignon Blanc. A California Chardonnay with its buttery notes complements the creamy mushroom sauce, while a New Zealand Sauvignon Blanc adds a bright citrus contrast that cuts through the richness.
I reach for Kim Crawford Sauvignon Blanc—its zesty lime and grapefruit flavors refresh your palate after each bite. 🍷
Light-Bodied Red
If you prefer red wine, a Pinot Noir from Oregon or Burgundy is ideal. The delicate berry and earthy notes won't overpower the dish but instead enhance the cheesy, savory flavors.
Look for a Willamette Valley Pinot Noir—its silky texture and subtle spice make it a perfect match for the nutmeg and garlic in the casserole. Avoid heavy reds like Cabernet Sauvignon, which would clash with the creamy texture.
Malty Amber Ale
For beer lovers, a German Amber Ale like Weihenstephaner Hefeweissbock or Ayinger Celebrator balances the dish's richness with its malty sweetness. The caramel and toasted notes in the beer mirror the golden-brown topping, while the effervescence cleanses your palate.
If you prefer something lighter, a Belgian Witbier with its coriander and citrus notes adds a refreshing twist. 🍺
Creamy Stout
A dark stout like Guinness or Samuel Smith's Oatmeal Stout might seem unexpected, but the roasted malt flavors actually complement the creamy mushroom sauce. The smooth, slightly sweet profile pairs surprisingly well with the cheesy, crispy layers.
For a modern twist, try a smoked porter—the smoky notes enhance the nutmeg and garlic in the casserole.
Non-Alcoholic Options
Skip the alcohol? No problem. A sparkling apple cider like Martinelli's adds a crisp, fruity contrast to the creamy dish. For something more savory, a ginger beer like Feather's with its spicy kick cuts through the richness.
Even a cucumber-mint infused water with a splash of lime keeps things refreshing while letting the casserole shine. 💧
Serving Temperature
Serve your wine or beer slightly chilled—about 45-50°F for whites, 55-60°F for reds, and 40-45°F for beers. The cooler temperature enhances the flavors without overwhelming the warm, comforting notes of the casserole. I always let my wine breathe for 10-15 minutes before pouring to bring out its best qualities. 🌡️

Frequently asked questions
Can I make this casserole without cream of mushroom soup?
For a homemade version, blend 1 cup sautéed mushrooms, 1 cup milk, 2 tablespoons flour, and 1 tablespoon butter until smooth. Add 1 teaspoon garlic powder and ½ teaspoon onion powder for depth. The texture will be slightly thicker but still creamy and delicious.
Why does my casserole turn out watery?
Watery casseroles usually happen when the beans are rinsed (removing starch) or too much liquid is added. Always drain your green beans but don't rinse them—the starch helps thicken the sauce. Also, check your soup measurements: 2 cans soup + ½ cup milk is perfect. If it's still too thin, bake uncovered for 5-10 extra minutes to evaporate excess moisture.
How can I make this gluten-free?
Swap the all-purpose flour topping for ½ cup gluten-free flour blend or ½ cup crushed gluten-free crackers. Use ½ cup gluten-free breadcrumbs mixed with ¼ cup melted butter instead of French fried onions. The texture will still be crispy, just without the wheat. Always check labels—some gluten-free flours need extra moisture.
Can I prepare this ahead of time?
Yes! Assemble the casserole (up to the topping) and refrigerate for up to 24 hours before baking. Add the topping just before baking to keep it crispy. For make-ahead meals, bake it 30 minutes, cool completely, then refrigerate. Reheat covered with foil at 350°F for 20-25 minutes until bubbly. The flavors actually improve overnight!
What's the secret to extra crispy fried onion topping?
Toast your French fried onions in a dry skillet over medium heat for 2-3 minutes before adding them to the casserole. This enhances their flavor and crunch. For even more crispiness, sprinkle the topping with 1 tablespoon melted butter right before baking. Press it down firmly so it doesn't shift during baking. The result? A golden, shatteringly crisp layer that's worth the extra effort!
