Ingredients List for the Best Green Bean Casserole
To make the perfect green bean casserole, you need a combination of fresh, savory, and creamy ingredients. Here's what you’ll need:
- 1 pound fresh green beans: Trimmed and cut into bite-sized pieces. You can use frozen or canned beans as a substitute.
- 1 can (10.5 oz) condensed cream of mushroom soup: This is the base for the creamy sauce. For a richer flavor, you can use homemade mushroom soup.
- ¾ cup milk: Helps thin out the soup to the perfect consistency.
- 1 cup shredded cheddar cheese (optional): For added richness and flavor.
- 1 teaspoon soy sauce: Adds a touch of umami flavor.
- ½ teaspoon black pepper: Freshly ground for the best flavor.
- 1 ½ cups crispy fried onions: These add the iconic crunchy topping.
- Salt to taste: Enhances all the flavors.
Substitutions and Variations
One of the best things about green bean casserole is how versatile it can be. Whether you're accommodating dietary restrictions or simply want to try a twist on the original recipe, here are a few substitutions and variations you can explore:
- Vegan option: Swap the cream of mushroom soup for a vegan cream soup (you can find several brands or make your own with non-dairy milk and flour). Replace the milk with almond or oat milk, and use a vegan cheese substitute if desired.
- Gluten-free version: Use gluten-free cream of mushroom soup and substitute the crispy onions with a gluten-free version. Many stores now offer gluten-free fried onions.
- Alternative toppings: If you’re not a fan of crispy onions, try topping your casserole with breadcrumbs or even crushed Ritz crackers for a buttery crunch.
- Cheesy green bean casserole: Add extra shredded cheese on top or mix it into the casserole for a gooey, cheesy texture.
- Bacon twist: For added flavor, toss in crumbled bacon or pancetta to give the casserole a smoky kick.
Step-by-Step Cooking Instructions

Here’s a simple, step-by-step guide to making your green bean casserole from scratch:
- Preheat your oven to 350°F (175°C). This ensures the casserole will bake evenly.
- Cook the green beans: If using fresh green beans, bring a large pot of water to a boil, add a pinch of salt, and blanch the beans for 5 minutes until bright green and slightly tender. Drain and rinse under cold water to stop the cooking process. If using frozen green beans, thaw them, and if you're using canned beans, simply drain them well.
- Mix the sauce: In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, black pepper, and half of the crispy fried onions. Stir until well combined.
- Combine the beans and sauce: Add the cooked (or drained) green beans to the bowl with the sauce and mix until the beans are fully coated.
- Prepare to bake: Transfer the green bean mixture to a 9x13-inch baking dish, spreading it out evenly.
- Add the topping: Sprinkle the remaining crispy fried onions on top. If you’re adding cheese, sprinkle that on top as well.
- Bake: Place the casserole in the oven and bake for 25-30 minutes or until the casserole is bubbling and the onions are golden and crispy.
- Cool and serve: Remove the casserole from the oven and let it cool for a few minutes before serving.
How to Cook Green Bean Casserole: A Step-by-Step Guide
To make sure your green bean casserole comes out perfect every time, follow this breakdown of the key steps:
- Prepare the Beans: Blanching the green beans is essential to retain their vibrant color and keep them slightly crisp. Overcooking the beans can make them mushy in the casserole.
- Make the Creamy Sauce: The cream of mushroom soup and milk combination is the foundation of the casserole’s creaminess. You can play with this by adding different seasonings, like garlic powder or paprika, for an extra flavor boost.
- Layering and Topping: Make sure to evenly distribute the crispy onions on top to ensure that each bite has a perfect crunch.
- Baking the Casserole: Keep an eye on the casserole during the last few minutes of baking to prevent the onions from burning. You want a golden brown top, not a blackened one!
Common Mistakes to Avoid
Even though green bean casserole is a fairly simple dish, there are some common mistakes to be aware of:
- Overcooking the green beans: If your beans are too soft before baking, they’ll end up mushy.
- Not seasoning enough: Don’t forget to season your casserole with salt and pepper! The creaminess of the dish needs some seasoning to balance it out.
- Burning the onions: If the crispy onions are browning too quickly, you can cover the casserole with foil during the last few minutes of baking to avoid burning.
- Using the wrong dish size: Make sure you use a large enough casserole dish to avoid overcrowding the ingredients. A 9x13-inch dish works best.
Serving and Presentation Tips
Green bean casserole is a simple dish, but that doesn't mean it can't look impressive on the table. Here are some serving tips to make your casserole shine:
- Garnish with Fresh Herbs: After baking, sprinkle freshly chopped parsley or thyme over the top for a pop of color and added flavor.
- Serve in a Beautiful Dish: If you're serving this at a holiday meal, consider baking the casserole in a decorative ceramic dish that complements your table setting.
- Make Mini Casseroles: For a fun twist, divide the mixture into individual ramekins for personal-sized servings. This can elevate the presentation for a dinner party.

Green Bean Casserole Recipe Tips
