Ingredients You’ll Need
-
4 cups cooked or canned green beans, drained
-
1 can (10.5 oz) condensed cream of mushroom soup
-
1/2 cup milk
-
1 teaspoon soy sauce
-
1/4 teaspoon black pepper

1 1/3 cups French fried onions, divided

Step-by-Step Instructions
1. Preheat the Oven
Set your oven to 350°F (175°C). Preheating ensures even cooking and gives your casserole that golden, bubbly finish.
2. Mix the Ingredients
In a large mixing bowl, combine:
-
Cream of mushroom soup
-
Milk
-
Soy sauce
-
Black pepper
Stir until smooth. Add the green beans and 2/3 cup of the fried onions. Mix until the beans are well coated.
3. Bake
Transfer the mixture into a lightly greased baking dish. Bake uncovered for 25 minutes. This step helps the casserole set and the flavors to meld beautifully.
4. Add the Crunch
Remove from the oven, stir gently, then sprinkle the remaining 2/3 cup of fried onions over the top. Bake an additional 5–10 minutes, or until the top is golden and crispy.
5. Serve
Let it rest for a few minutes, then serve warm. The creamy base paired with the crunchy topping is absolute comfort food heaven.

Tips for Success
-
Use fresh green beans for a more vibrant color and texture. Simply blanch them for 3–4 minutes in boiling water and shock them in ice water before using.
-
Low-sodium alternatives: Use low-sodium mushroom soup or low-sodium soy sauce if you’re watching salt intake.
-
For extra flavor, add a pinch of garlic powder, a splash of Worcestershire sauce, or a few dashes of hot sauce to the soup mixture.
-
Customize the crunch: Swap French fried onions for crushed Ritz crackers, breadcrumbs, or even crispy bacon for a twist.
-
Make it cheesy: Add 1/2 cup shredded cheddar or Parmesan to the mix for a cheesy upgrade.

Frequently Asked Questions
Can I make this ahead of time?
Absolutely. Prepare the casserole up to the point of baking and refrigerate it, covered, for up to 24 hours. Add the fried onions just before baking for the best texture.
Can I double the recipe?
Yes! This recipe doubles easily. Use a 9×13-inch dish and increase the initial bake time to 30–35 minutes before adding the topping.
Can I use frozen green beans?
Yes, just make sure they’re thawed and drained well to prevent excess moisture in the casserole.
Why is my casserole runny?
This can happen if your green beans weren’t well-drained. Be sure to fully drain canned or cooked beans and avoid adding extra liquid.
Is this casserole healthy?
It’s a comfort food classic, so it leans indulgent. However, using low-fat soup and milk, and cutting back on the fried onions can lighten it up.
