| Ingredient | Amount | Notes |
|---|---|---|
| Canned Green Beans 🌱 | 2 cups | Drained, not pre-cooked |
| Campbell's Cream of Mushroom Soup 🍄 | 2 cups | Condensed, not ready-to-serve |
| All-Purpose Flour 🌾 | ½ cup | For crispy topping |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for topping |
| French Fried Onions 🧅 | ½ cup | Seasoned, for crunch |
| Milk 🥛 | ¼ cup | Whole milk for creaminess |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |

The Campbell's cream of mushroom soup is non-negotiable here—it's the heart of that nostalgic flavor. Grab the condensed version (not ready-to-serve) from any grocery store aisle, but check the expiration date. Old cans lose their richness, so if you've had it sitting for months, swap for a fresh one. For the green beans, canned works perfectly—just drain and rinse to remove excess sodium. If you prefer fresh, blanch them for 2 minutes first. The French fried onions should be the seasoned kind from the canning aisle—Trader Joe's and Walmart both carry excellent options. These add that signature crunch that makes this dish special.
No Campbell's cream of mushroom? Cream of celery soup thinned with milk works in a pinch, though the flavor won't be identical. Short on French fried onions? Crushed potato chips (like Ruffles) give a similar texture—just season them with salt and pepper. The butter topping is where the magic happens—use full-fat, cold butter for maximum crispiness. If you're watching fat, you can substitute half butter, half olive oil, but the texture won't be as crisp. For the milk, whole milk gives the creamiest result, but 2% works fine if that's what you have. The garlic and onion powders are just for depth—skip them if you're in a rush, but they elevate the flavor significantly.
This casserole reheats beautifully—cover with foil and bake at 350°F for 15-20 minutes until warmed through. Leftovers keep for 4-5 days in the fridge, but the topping loses crispiness after day 2. For best results, make it a day ahead—flavors meld overnight, and the topping stays perfectly crunchy. Portion into individual dishes before baking if you're serving a crowd—this keeps everything neat and prevents soggy tops. If you're freezing, assemble and bake first**, then freeze the whole casserole. It reheats just like fresh from the oven.

Step-by-step instructions for Campbell's green bean casserole
Here's the method for achieving that perfect balance of crispy golden topping and creamy mushroom sauce.
Prepare the Green Bean Base
Drain the 2 cups of canned green beans thoroughly using a colander, shaking gently to remove excess liquid. I like to spread them on a paper towel-lined plate to ensure they're completely dry—this prevents a watery casserole. In a large mixing bowl, combine the drained green beans with the 2 cups of Campbell's Cream of Mushroom Soup. Stir gently to coat the beans evenly with the sauce, making sure each bean gets a good covering. Set this mixture aside while you prepare the topping.
This step ensures your green beans absorb the rich mushroom flavor throughout. If you notice any large stems or tough ends, trim them off now for a more pleasant texture. The beans should be evenly coated but not mushy—this is your foundation for the creamy magic to come.
Create the Crispy Topping Mixture
In a medium bowl, whisk together the 0.5 cup of all-purpose flour, 0.25 tsp of Diamond Crystal baking powder, 0.5 tsp of salt, 0.5 tsp of garlic powder, 0.5 tsp of onion powder, and 0.25 tsp of ground black pepper. This dry mixture forms the backbone of your crispy topping. Cut the 0.5 cup of unsalted butter into small cubes and add them to the dry ingredients. Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
Add the 0.5 cup of French fried onions and the 0.25 cup of milk to the bowl. Mix gently with a fork or rubber spatula until just combined—overmixing develops gluten and makes the topping tough instead of crispy. The mixture should hold together when pressed but still look slightly crumbly. This texture is crucial for that perfect golden crust.
Assemble and Bake for Crispy Perfection
Preheat your oven to 350°F. Grease a 9x13-inch baking dish with butter or nonstick spray—this prevents sticking and makes cleanup easier. Spread the green bean and mushroom soup mixture evenly in the prepared baking dish, pressing down gently to create an even layer. This ensures even cooking and prevents a thick center that might stay undercooked.
Spoon the topping mixture over the green beans, spreading it evenly across the surface. Use the back of a spoon to create small peaks and valleys in the topping—this helps it crisp up more thoroughly during baking. Bake for 30 minutes until the edges of the topping are golden brown and the center is bubbling. The casserole should smell rich and savory, with a slightly nutty aroma from the crisping topping.
Achieve the Perfect Texture
Remove the casserole from the oven and let it rest for 5 minutes. This resting period allows the topping to set slightly and the flavors to meld together. You'll notice the topping will continue to crisp up as it cools—this is normal and actually enhances the texture. Use a kitchen towel to carefully wipe away any excess moisture from the edges of the baking dish, which can prevent the topping from getting as crispy.
Cut into 6 equal portions and serve immediately. Each bite should deliver that perfect combination of creamy mushroom sauce with crispy, golden-brown topping. If you prefer an extra crispy edge, broil for 1-2 minutes at the end of baking—just watch closely to prevent burning. The contrast between the creamy filling and crispy topping is what makes this classic casserole so irresistible.
Pro Tips For Making Campbell'S Green Bean Casserole Recipe With Cream Of
- Drain Beans Thoroughly: I learned this the hard way—skipping this step turns your casserole into a watery mess. Dump those beans into a colander, give them a good shake, and let them drain for a full minute. The extra moisture in the beans makes the soup mixture thin out faster than you’d expect, and you’ll end up with a sad, soupy side instead of the creamy texture you want.
- Toast the Flour First: Sounds weird, but it works: dry-toast your 2 tablespoons of flour in the butter for 30 seconds before adding liquid. This removes the raw flour taste and gives the topping a slightly nutty depth—like a subtle upgrade to the classic crumbly texture. Just don’t walk away; it burns faster than you think.
- Layer the Onions Last: Sprinkle those French fried onions right before baking, not while mixing. They’ll stay crispy instead of soggy, and you’ll avoid the greasy mess that happens when they sit in the soup mixture too long. If you’re impatient like me, at least add them in the final 10 minutes of baking so they don’t turn into mush.
- Bake Until Bubbly: Don’t peek! The casserole needs 20-25 minutes at 350°F until the edges are golden and the center is just starting to bubble. Pulling it too early means a gummy topping, and no one wants that. If it’s not bubbling, give it 5 more minutes—your future self will thank you.
Perfect pairings for this recipe

The French fried onions in the casserole add a satisfying crunch that contrasts perfectly with tender meats.
Beverage Pairings
A crisp Chardonnay with buttery notes enhances the creamy mushroom flavor without overpowering it. For beer lovers, a honey lager like Leinenkugel's Honey Weisse complements the sweetness of the onions and balances the savory depth.
I also enjoy sparkling apple cider during the holidays—its acidity refreshes the palate between bites of rich casserole. 🍷
Make-Ahead Serving
Assemble the casserole a day ahead and refrigerate uncovered to let the topping crisp up naturally. Reheat covered with foil at 350°F for 15 minutes before serving. For potlucks, transfer to an insulated serving tray—the crispy topping stays intact even when carried.
I always bring this dish to gatherings because it reheats beautifully and tastes even better the next day.
Dessert Complements
Finish the meal with pumpkin pie or pecan pie—the warm spices in the dessert contrast beautifully with the casserole's savory notes. For a lighter option, serve with vanilla ice cream and a drizzle of caramel sauce to balance the richness.
I love setting out miniature casserole cups as a dessert appetizer—just add a dollop of whipped cream for a sweet twist. 🍰
Seasonal Variations
In summer, swap French fried onions for crushed potato chips and add fresh green beans sautéed with garlic. For winter, boost the topping with crumbled bacon and sharp cheddar cheese for extra richness.
I also love adding crushed Ritz crackers to the topping for a buttery crunch that works year-round. The key is keeping that perfect creamy-crispy balance. 🌶️

Frequently asked questions
Why does my topping get soggy instead of crispy?
Soggy topping usually happens when the green bean mixture isn't fully drained or the oven temperature isn't hot enough. Always pat the green beans completely dry and press them gently into the baking dish to remove excess moisture. For extra crispiness, bake at 375°F instead of 350°F and consider broiling for 1-2 minutes at the end. The topping needs time to set after baking too—let it rest for 5-10 minutes before serving.
Can I make this casserole ahead of time?
Assemble the dish completely (including the topping) and refrigerate uncovered for up to 24 hours before baking. The topping will crisp up beautifully overnight. For leftovers, reheat covered with foil at 350°F for 15 minutes—the topping may soften slightly but still taste delicious. This makes it perfect for holiday prep!
What's the best way to substitute French fried onions?
If you can't find French fried onions, crushed potato chips (like Ruffles) work perfectly—they add a similar crunch. For a more traditional approach, try finely chopped toasted breadcrumbs mixed with a little butter and seasoning. The key is maintaining that crispy texture, so avoid using soft ingredients like regular breadcrumbs.
Is this casserole vegetarian-friendly?
Yes, this classic recipe is naturally vegetarian! The main ingredients are plant-based, and you can easily make it vegan by using plant-based butter and milk. For extra flavor, consider adding vegetarian bacon bits or nutritional yeast to the topping. It pairs beautifully with vegetarian mains like stuffing or roasted vegetables.
How do I scale this recipe for a crowd?
Double the ingredients and use a 9x13-inch baking dish for 12 servings, or a 13x9x3-inch dish for 16 servings. For large gatherings, consider making two smaller casseroles instead of one giant one—this ensures even cooking and crispy toppings. Bake times remain the same, but check for doneness at 25 minutes to account for larger volumes.
