Ingredients You’ll Need
Ready to make the easiest Thanksgiving side dish? These pantry-friendly ingredients come together effortlessly.
Base ingredients:
- 2 cans (14.5 oz each) green beans, drained
- 1 can (10.5 oz) cream of mushroom soup
- ¾ cup whole milk
- ½ teaspoon soy sauce
- ¼ teaspoon black pepper
Topping:
- 1½ cups French’s crispy fried onions, divided
Canned green beans save time and work perfectly in this creamy casserole. French-cut or regular beans both taste great—choose whichever your family prefers. Fresh or frozen green beans work too if you cook them until tender first.
Campbell’s condensed cream of mushroom soup delivers the best flavor and consistency. Other brands tend to be thinner and don’t taste the same. Whole milk creates richness, but 2% milk works if that’s what you have.
Step-by-Step Instructions
1. Mix the creamy base by combining cream of mushroom soup with milk in a large mixing bowl. Whisk until completely smooth with no lumps remaining, then stir in soy sauce and black pepper.
2. Add the green beans to the mushroom mixture and stir until every bean gets coated with creamy sauce. Fold in ½ cup of French’s fried onions so they’re distributed throughout.
3. Transfer to baking dish by pouring the entire green bean mixture into a 2-quart casserole dish. Spread it evenly with a spatula so everything bakes uniformly.
4. Bake uncovered at 350°F for 30 minutes until the casserole is hot and bubbly around the edges. Remove from oven and give it a quick stir to redistribute the sauce.
5. Add the crispy topping by sprinkling remaining 1 cup of fried onions over the top. Return to oven for 5-10 minutes until onions turn golden brown and extra crispy.
Essential Equipment
2-Quart Casserole Dish
A ceramic or glass baking dish distributes heat evenly for perfectly cooked casserole. The 2-quart size fits the entire recipe without overflow or wasted space.
Large Mixing Bowl
Combining ingredients in a spacious bowl prevents spills and makes stirring easier. Glass or stainless steel options won’t retain odors from previous recipes.
Wire Whisk
Whisking soup and milk together eliminates lumps for silky-smooth sauce. The thin wires incorporate liquid faster than a spoon or spatula.
Silicone Spatula (PREMIUM)
Heat-resistant silicone won’t melt when scraping hot casserole dish edges. The flexible blade reaches every corner to get every last bit of creamy sauce.

Reheating Instructions
Thaw frozen casserole overnight in the refrigerator if you froze it ahead. Bake at 350°F for 30-35 minutes until heated through, then add crispy onions during the last 5 minutes.

Pro Tips and Tricks
Want your green bean casserole to turn out restaurant-quality every single time? Follow these expert secrets.
Don’t skip the soy sauce even though it seems like an odd addition to this recipe. That small amount adds incredible savory depth without making it taste Asian.
Use Campbell’s brand soup because other brands of cream of mushroom soup taste different and have thinner consistency. The color and flavor won’t match what you expect from classic green bean casserole.
Reserve some fried onions for the topping instead of mixing them all in at once. Those crispy golden onions on top are what people remember most about this dish.
Stir halfway through baking to redistribute the sauce and ensure even heating throughout. Some edges cook faster than the center without this quick stir.
Frequently Asked Questions
Can you make green bean casserole recipe ahead of time?
Yes, assemble it completely the day before without adding the final fried onion topping. Cover with plastic wrap and refrigerate overnight, then bake as directed the next day.
What kind of green beans work best?
Canned green beans are traditional and convenient, but you can use fresh or frozen. Cook fresh or frozen beans until tender before adding to the casserole.
Can you freeze green bean casserole?
Absolutely! Assemble without the final onion topping, wrap tightly with plastic and foil, then freeze up to 2 weeks. Thaw overnight in the fridge before baking.
Why does my casserole come out watery?
Make sure to drain canned green beans thoroughly before mixing them with the soup. Excess liquid from the beans dilutes the creamy sauce.
Can you substitute cream of mushroom soup?
Yes, make homemade by sautéing 12 ounces mushrooms in 3 tablespoons butter (halal-certified) until browned, then adding 1 cup milk and 4 ounces cream cheese. Best Marry Me Chicken Soup Recipe shows another way to create creamy soup-style sauces from scratch.
How do you keep fried onions crispy?
Add them during the last 5-10 minutes of baking rather than at the beginning. This prevents them from getting soggy before the casserole finishes cooking.
