Here is what I love most about this dish
- It uses pantry staples that you probably already own.
- It is idiot proof. Seriously, even I have not messed it up.
- It reheats like a dream so you get leftovers that are almost better than day one.
Ingredients You’ll Need
- 1 can (10.75 oz) Campbell’s condensed cream of mushroom soup
- 1/2 cup milk
- 1/4 teaspoon ground black pepper
- 1 teaspoon soy sauce
- 4 cups green beans fresh frozen thawed or canned drained
- 1 1/3 cups crispy fried onions divided
Pro tip Use good drained green beans and do not skip the soy sauce. It adds a salty umami boost that makes everything taste more composed.
Step-by-Step Instructions
Preheat Oven
Preheat your oven to 350ยฐF (175ยฐC). This crucial first step ensures even cooking from the moment your dish enters. Heat makes everything behave better during baking.Prepare Baking Dish
Select a 1.5 quart or 2 quart baking dish. A 9×13 inch dish also works beautifully for a slightly thinner casserole. Lightly grease the bottom and sides with cooking spray or a thin layer of butter.Drain Green Beans
If using canned green beans drain them exceptionally well. If using frozen thaw and drain them thoroughly. For an even drier result pat them dry with a towel.Combine Soup Milk and Seasonings
Empty the can of Campbell’s condensed cream of mushroom soup into a large bowl. Add the half cup of milk 1/4 teaspoon black pepper and 1 teaspoon soy sauce. Whisk until smooth and lump free.Fold in Green Beans and Onions
Add the drained green beans to the bowl. Measure out about two thirds of the crispy fried onions roughly 7/8 cup. Gently fold beans and onions into the sauce so every bean gets coated without getting mashed.Pour into Baking Dish
Spoon the green bean mixture into your prepared dish. Use a spatula to spread it evenly. A flat surface helps with even baking and a prettier final crust.Initial Bake
Place the dish in your preheated oven. Bake uncovered for 25 to 30 minutes. The sauce should heat through and start to bubble around the edges.Add Remaining Onions
Carefully remove the hot casserole from the oven after 25 to 30 minutes. Sprinkle the remaining crispy fried onions about 1/2 cup over the surface. Cover any bare spots so every bite gets crunch.Final Bake
Return the casserole to the oven. Bake an additional 5 to 10 minutes until the top onions are golden brown and crispy. Watch closely because they can shift from perfect to too dark fast.Rest Before Serving
Let the casserole rest for 5 to 10 minutes before serving. This helps the sauce set so you can serve tidy portions and avoids molten face burns.

Common Mistakes to Avoid
- Not draining the green beans well enough. Extra liquid makes the casserole runny and sad.
- Skipping the soy sauce. That little splash amps up flavor in a way plain salt cannot.
- Adding all the onions at the start. They will lose their crunch and become soggy. Save some for the last five minutes.
- Ignoring oven temperature. Too hot and the top burns while the middle lags. Preheat and trust the time.
- Not letting it rest. Serve too soon and you get a sloppy scoop. Patience wins.
Alternatives & Substitutions
- Use fresh green beans for a snap that screams freshness. Blanch them first for a couple of minutes then shock them in ice water. IMO blanched fresh beans make the casserole feel less canned and more like you actually tried.
- Swap milk for half and half if you want a richer sauce. This makes it silkier but also heavier. Balance accordingly.
- Want bacon Go ahead and crisp up 4 strips and crumble them into the mix. That smoky saltiness is a game changer.
- Vegetarian option Already vegetarian if you use the standard soup but double check any added ingredients for hidden animal products.
- Cheese fan Add 1/2 cup shredded cheddar on top with the final onions for a cheesy crust. Not traditional but very good.
FAQ

Q Can I use margarine instead of butter
Well technically yes but why hurt your soul like that Use butter or a neutral oil for greasing the dish.
Q Can I use fresh mushrooms instead of condensed soup
You could but then it stops being a quick weeknight hack and becomes a different recipe. If you want to go that route sautรฉ mushrooms with cream and a bit of flour until thickened.
Q How long can I keep leftovers
Store in an airtight container in the fridge for 3 to 4 days. Reheat covered in a 350ยฐF oven until warm or microwave in portions.
Q Can I assemble ahead of time
Yes assemble up to the point of adding the final onions and refrigerate. Add the onions then bake when you are ready. This saves time on serving day.
Q Do I have to use Campbell’s soup
No but Campbell’s gives that classic taste. If you use another brand you may notice a flavor difference. If you want to experiment go for it.
Q Can I freeze this casserole
You can freeze the assembled casserole before baking for up to 2 months. Thaw overnight in the fridge then bake as instructed. Avoid adding crunchy onions before freezing.
Q Any tips for making it crunchier
Add half the onions before and half at the end and briefly broil if you like things super crisp. Watch carefully when broiling.
