What is Green Bean Casserole?
Green Bean Casserole is a creamy, savory dish made with cooked green beans, a mushroom-based sauce, and topped with crispy fried onions. This dish was created in the 1950s by Campbell's Soup and has since become a beloved side dish, especially during holiday meals. While many versions rely on canned soup and pre-cooked green beans, this recipe focuses on a homemade mushroom sauce for a fresher, richer flavor. It’s comforting, crunchy, and a perfect addition to any meal.
Ingredients List for Green Bean Casserole
Here’s what you’ll need to make this Green Bean Casserole from scratch:
- Fresh green beans (1 ½ lbs, trimmed and cut into 2-inch pieces): Fresh beans provide the best texture and flavor.
- Butter (2 tbsp): For sautéing and adding richness to the dish.
- Mushrooms (8 oz, sliced): Cremini or button mushrooms add an earthy flavor to the casserole.
- Garlic (2 cloves, minced): Adds extra flavor to the sauce.
- All-purpose flour (2 tbsp): Helps thicken the mushroom sauce.
- Chicken or vegetable broth (1 cup): Forms the base of the creamy sauce.
- Heavy cream (1 cup): Makes the sauce rich and creamy.

Substitutions and Variations
One of the best things about Green Bean Casserole is how easy it is to adapt based on your preferences. Here are some common substitutions and variations:
- Green Beans: You can substitute fresh green beans with frozen ones if you’re short on time. Just thaw them before adding to the recipe.
- Mushroom Soup: If you prefer the classic version with condensed mushroom soup, you can replace the homemade sauce with one can of cream of mushroom soup mixed with ½ cup of milk.
- Gluten-Free: Use gluten-free flour and gluten-free crispy onions for a gluten-free version.
- Cheesy Twist: Add shredded cheddar or Gruyère cheese to the sauce for a cheesy green bean casserole.
- Healthier Option: Use low-fat milk or Greek yogurt instead of heavy cream for a lighter version of the sauce.
Step-by-Step Cooking Instructions
Here’s how to make the perfect Green Bean Casserole from scratch:
Step 1: Preheat the Oven and Cook the Green Beans
Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for 4-5 minutes until tender-crisp. Drain the beans and immediately transfer them to a bowl of ice water to stop the cooking process. Drain again and set aside.
Step 2: Sauté the Mushrooms
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the sliced mushrooms and cook for about 5-7 minutes, stirring occasionally, until the mushrooms are browned and have released their moisture. Add the minced garlic and cook for another 30 seconds until fragrant.
Step 3: Make the Mushroom Sauce
Sprinkle the flour over the mushrooms and garlic, stirring constantly for 1-2 minutes to cook the flour. Slowly pour in the chicken or vegetable broth, whisking to combine. Let the sauce simmer for 3-4 minutes until it thickens. Stir in the heavy cream, soy sauce, salt, and pepper. Simmer for another 2-3 minutes until the sauce is creamy and smooth.
Step 4: Combine the Green Beans and Sauce
Add the blanched green beans to the skillet with the mushroom sauce, tossing to coat the beans evenly. Season with additional salt and pepper if needed.
Step 5: Transfer to a Baking Dish
Transfer the green bean mixture to a greased 9x13-inch baking dish. If you want a cheesy version, sprinkle grated parmesan or cheddar cheese on top of the green beans.
Step 6: Add Fried Onions and Bake
Sprinkle 1 cup of the crispy fried onions over the green beans. Place the casserole in the preheated oven and bake for 15-20 minutes, or until the sauce is bubbling and the onions are golden and crispy.
Step 7: Serve
Remove the casserole from the oven and sprinkle the remaining ½ cup of fried onions on top for extra crunch. Serve hot and enjoy!
How to Cook Green Bean Casserole: A Step-by-Step Guide
Cooking the perfect Green Bean Casserole is all about getting the balance between creamy, savory sauce and crispy, crunchy topping. Fresh green beans provide the best texture, but frozen beans work in a pinch. A homemade mushroom sauce elevates the dish by offering more depth and richness than the traditional canned soup version. Don’t skip blanching the beans, as it keeps them tender-crisp even after baking.
To ensure the onions stay crispy, bake the casserole uncovered and add half of the onions at the end for that perfect crunch in every bite.
Common Mistakes to Avoid
- Overcooking the Green Beans: Be careful not to overcook the green beans during the blanching process. You want them to be tender-crisp, as they’ll cook further in the oven.
- Watery Sauce: If your sauce is too thin, cook it a bit longer on the stovetop to allow it to thicken properly. You can also add a bit more flour if needed.
- Soggy Onions: To keep the fried onions crispy, only add half before baking and sprinkle the rest on top after the casserole is done baking.
