Serves: 8 people

Ingredients You’ll Need
For the Casserole
- 2 cans (14.5 ounces each) cut green beans, drained
- 1 can (10.5 ounces) Campbell’s Condensed Cream of Mushroom Soup
- 3/4 cup whole milk
- 1 teaspoon soy sauce
- 1/4 teaspoon black pepper
For the Topping
- 1 1/3 cups crispy fried onions, divided
Optional Add-Ins
- 1/2 cup shredded cheddar cheese
- 4 slices cooked bacon, crumbled
- 1/2 cup sautéed mushrooms
- 1/4 teaspoon garlic powder
- 1 tablespoon grated Parmesan cheese
Pro Tips
- Drain the green beans well before mixing. Extra liquid can thin the sauce and make the casserole watery.
- Stir the soup mixture until completely smooth before adding the beans. This helps create an even creamy texture throughout the dish.
- Reserve part of the crispy onions for the final bake. This keeps the topping crunchy and fresh.
- Use a shallow baking dish when possible. More surface area means more golden topping in every serving.
- If making ahead, wait to add the onions until baking time. This prevents them from softening too early.
- Taste the filling before baking if adding extras like cheese or bacon. Some additions may change the seasoning balance.
Tools You’ll Need
- Large mixing bowl
- Spoon or spatula
- Measuring cup
- Measuring spoons
- Can opener
- 1 1/2-quart casserole dish or 9×9-inch baking dish

Substitutions and Variations
Cut green beans are the traditional choice, but French-style green beans also work well for a softer texture. Whole green beans can be used if you prefer a heartier bite.
Frozen green beans are another great option when you want a fresher texture. Thaw and drain them well before mixing into the casserole.
Cream of mushroom soup is the classic base, but cream of chicken or cream of celery soup can be substituted for a different flavor. Each version keeps the casserole creamy and comforting.
Whole milk gives a rich texture, though 2% milk or half-and-half can also be used. If using half-and-half, the casserole may be even creamier.
Soy sauce adds savory depth, but Worcestershire sauce can be used instead. A small amount goes a long way in boosting flavor.
For a cheesier version, stir shredded cheddar into the casserole before baking. It melts into the sauce and creates a richer result.
Cooked crumbled bacon is a favorite addition for many families. It adds smoky flavor that pairs beautifully with the crispy onions.
If you enjoy mushrooms, sauté fresh sliced mushrooms and stir them into the filling. This gives a more homemade mushroom flavor.
For extra crunch, combine crispy onions with buttered breadcrumbs. This creates a thicker golden topping that many guests enjoy.
Garlic powder or onion powder can be added for extra savory flavor. Just a small amount can make the casserole taste more robust.
To make it vegetarian-friendly, simply ensure your soup and toppings fit your dietary needs. Many versions already work well for meatless meals.
For gluten-free needs, use a gluten-free condensed soup and certified gluten-free crispy onions if available. Always check labels carefully.
A pinch of smoked paprika can add warmth and subtle depth. It also pairs nicely with any bacon additions.
If you like a creamier casserole, add a spoonful of sour cream or cream cheese to the filling. It blends in smoothly and creates a richer texture.
Mini baking dishes are a fun option for smaller gatherings. They also make portioning easier and can be useful for gifting.
No matter how you customize it, keeping that crisp onion topping is what makes this classic casserole instantly recognizable and comforting.
Make Ahead Tips
Campbell’s Green Bean Casserole is one of the easiest holiday sides to prepare ahead. You can mix the green beans, soup, milk, soy sauce, and pepper up to one day in advance. Transfer the mixture to the baking dish, cover tightly, and refrigerate until ready to bake.
For the best topping texture, keep the crispy fried onions separate until baking time. Adding them too early can cause them to soften before the casserole goes into the oven.
If the casserole has been chilled overnight, let it sit at room temperature for about 15 to 20 minutes before baking. This helps it heat more evenly.
You can also fully bake the casserole earlier in the day and reheat before serving. Add fresh onions during reheating to restore that classic crunch.
Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F. Lightly grease a 1 1/2-quart casserole dish or 9×9-inch baking dish.
Step 2: Mix the Sauce Base
In a large mixing bowl, combine the Campbell’s Condensed Cream of Mushroom Soup, milk, soy sauce, and black pepper. Stir until smooth and creamy.
Step 3: Add the Green Beans
Fold the drained green beans into the soup mixture. Stir gently until all the beans are evenly coated.
Step 4: Add Some Onions
Stir in about 2/3 cup of the crispy fried onions. Mixing some onions into the filling adds flavor throughout the casserole.
Step 5: Fill the Baking Dish
Transfer the mixture to the prepared baking dish. Spread it into an even layer with a spoon or spatula.
Step 6: First Bake
Bake uncovered for 25 minutes until the casserole is hot and bubbling around the edges.
Step 7: Add Final Topping
Carefully remove the dish from the oven. Sprinkle the remaining crispy fried onions evenly over the top.
Step 8: Finish Baking
Return the casserole to the oven and bake for 5 more minutes, or until the onions are golden and crisp.
Step 9: Rest Before Serving
Let the casserole rest for 5 minutes after baking. This helps the filling settle and makes serving easier.
Step 10: Serve Warm
Spoon onto plates while warm and enjoy as a classic side dish.
