Ingredients
Gather these simple ingredients for your perfect Classic Green Bean Casserole:
- 4 cups frozen cut green beans (see notes for canned or fresh beans)
- 1 (10.5 ounce) can condensed cream of mushroom soup
- ½ cup milk
- 1 teaspoon soy sauce
- ½ teaspoon black pepper
- ¼ teaspoon seasoned salt (more to taste)
- 1½ cups crispy fried onions (divided)
Notes & Substitutions
- Green Beans: Frozen cut green beans work wonderfully. For fresh, trim and blanch 1 pound until tender-crisp. If using canned, drain three 14.5-ounce cans thoroughly before mixing.
- Soup: Cream of chicken or celery soup make great alternatives if you don’t prefer mushroom. Opt for a low-sodium version if you are mindful of salt intake.
- Crispy Fried Onions: French’s brand is classic for a reason; its distinctive crunch is essential. Don’t skimp on these for the best texture.
- Cheese: A ½ cup of shredded cheddar or Gruyere cheese adds a delightful richness. Stir it in with the green beans for extra flavor.
- Garlic: Add ½ teaspoon of garlic powder or one minced fresh garlic clove for an aromatic boost.
- Topping Variation: For an extra crispy topping, combine ½ cup panko breadcrumbs with 2 tablespoons melted butter. Sprinkle this over the casserole before adding the final layer of fried onions.
Equipment
You won’t need much to prepare this delightful green bean casserole. Gather a medium pot for blanching beans and a large mixing bowl. You will also need a 2-quart baking dish. This ensures proper cooking and presentation.
Instructions
Prepare your delightful Classic Green Bean Casserole with these simple, step-by-step directions.
- Preheat Oven: First, preheat your oven to 350°F (175°C). This ensures the oven is ready when your casserole is assembled.
- Cook Green Beans: Bring a medium pot of salted water to a boil. Add the frozen green beans and boil them until they are tender-crisp, about 2 to 3 minutes. Drain the green beans well.
- Combine Ingredients: In a large bowl, combine the drained green beans with the condensed cream of mushroom soup, milk, soy sauce, black pepper, and seasoned salt. Stir everything together until it is well combined. If you are using cheese, stir it in now. Add 1 cup of crispy fried onions to the mixture and stir gently.
- Transfer to Dish: Transfer the entire mixture to a 2-quart baking dish. Spread it evenly across the bottom of the dish.
- Initial Bake: Bake the casserole uncovered for 30 to 35 minutes, or until the mixture is bubbly around the edges. This allows the flavors to meld and the casserole to heat through.
- Add Final Topping: Remove the casserole from the oven. Gently stir the mixture to redistribute the flavors. Top evenly with the remaining ½ cup of crispy fried onions.
- Final Bake: Return the casserole to the oven for an additional 10 minutes, or until the onions are golden brown and crisp. This final step gives your green bean casserole that signature crunchy topping. Serve immediately and enjoy!

Pro Tips & Troubleshooting
Prep-Ahead Perfection
Make-ahead Green Bean Casserole is a game changer for busy schedules. Prepare your casserole up to 48 hours in advance, following all steps except adding the final crispy onions. Cover the dish tightly and refrigerate. Store the crispy onions separately at room temperature. Bring the chilled casserole to room temperature for about 30 minutes before baking. Adjust the baking time by adding an extra 10-15 minutes if baking from cold.
Doubling the Recipe
To serve a larger crowd, easily double this Classic Green Bean Casserole recipe. Use a larger 9×13 inch baking dish for the increased volume. You will need to increase the baking time by approximately 10-15 minutes during the initial bake. Always ensure the center is bubbly hot and cooked through before adding the final onion topping.
Travel & Transport
Bake your casserole partially before traveling to your event. Cover it tightly with foil to keep it warm during transport. Finish baking at your destination until the onions are golden and the casserole is bubbly. This ensures a fresh, hot dish upon arrival.
Serving, Storage, and Variations
Serving Suggestions
Serve this comforting Classic Green Bean Casserole alongside your favorite holiday roast, like turkey or ham. It pairs wonderfully with classic meatloaf or roasted chicken for a weeknight dinner. For the best flavor and texture, serve it warm straight from the oven.
Storage & Reheating
Cool any leftover green bean casserole completely before storing. Transfer it to an airtight container and keep it in the refrigerator for up to 3-4 days. To reheat, gently warm portions in the microwave or place the entire dish in a 300°F (150°C) oven until heated through.
Freezing Instructions
You can freeze unbaked green bean casserole for future enjoyment. Assemble the casserole in a freezer-safe dish, omitting the crispy onions. Cover it tightly with plastic wrap and then foil.
