To make BA’s Ultimate Green Bean Casserole, you will need the following ingredients:

Fresh Green Beans

Start with fresh green beans for the best flavor and texture. Avoid using canned green beans, as they tend to be overly soft and lack the crispness that adds a delightful crunch to the casserole.


Choose your favorite variety of mushrooms for this recipe. Cremini or white button mushrooms work well and provide a savory depth of flavor.


A finely chopped onion adds aromatic sweetness to the casserole. Feel free to use either yellow or white onion, depending on your preference.


Garlic is a key ingredient that enhances the overall flavor profile of the casserole. Mince a clove or two for a subtle garlic kick.


Butter is the secret to making the casserole rich and indulgent. It adds a velvety smoothness to the dish and complements the other flavors perfectly.


A small amount of flour is used to create a roux, which helps thicken the creamy sauce in the casserole. Make sure to use all-purpose flour for this step.


For a luscious creamy sauce, use whole milk. It provides a creamy base that binds all the ingredients together.

Chicken Broth

Chicken broth adds depth and richness to the casserole. If you prefer a vegetarian version, you can substitute vegetable broth instead.

Soy Sauce

A dash of soy sauce adds a savory umami flavor to the casserole. It complements the mushrooms and enhances the overall taste of the dish.

Worcestershire Sauce

Worcestershire sauce adds a tangy and slightly sweet flavor to the casserole. It enhances the depth of the sauce and balances the richness of the other ingredients.

Salt and Pepper

Season the casserole to taste with salt and pepper. Remember to taste as you go and adjust the seasoning accordingly.

French Fried Onions

Sprinkle a generous amount of French fried onions on top of the casserole before baking. They add a delightful crunch and a burst of flavor to each bite.


Now that we have all the ingredients, let’s dive into the preparation process. This casserole is made in several steps to ensure each component is perfectly cooked and the flavors are balanced.

Blanching the Green Beans

Blanching the green beans ensures they are tender yet still crisp. Start by bringing a large pot of salted water to a boil. Add the green beans and cook for 2-3 minutes until they turn bright green. Immediately transfer them to a bowl of ice water to stop the cooking process. Once cooled, drain the green beans and set them aside.

Sauteing the Mushrooms

In a large skillet, melt butter over medium-high heat. Add the mushrooms, onion, and garlic, and sauté until the mushrooms are golden brown and the onion is translucent. This step adds depth and umami to the casserole.

Making the Cream Sauce

To make the creamy sauce, melt butter in a saucepan and whisk in the flour until a smooth paste forms. Gradually pour in the milk and chicken broth, whisking constantly to prevent any lumps. Bring the mixture to a simmer and cook until thickened. Stir in the soy sauce, Worcestershire sauce, salt, and pepper for added flavor.

Assembling the Casserole

In a large mixing bowl, combine the blanched green beans, sautéed mushrooms, and the creamy sauce. Gently fold together until all the ingredients are fully coated. Transfer the mixture to a greased baking dish and spread it evenly.

Baking the Casserole

Preheat the oven to 350°F (175°C). Place the green bean casserole in the oven and bake for 25-30 minutes, or until the top is golden brown and bubbling. During the last 5 minutes of baking, sprinkle the French fried onions over the casserole and return it to the oven until they are crisp and golden.

Cooking Tips

Now that you know the basic steps to make BA’s Ultimate Green Bean Casserole, let’s delve into some helpful cooking tips to ensure your dish turns out perfectly.

Fresh vs. Canned Green Beans

Using fresh green beans will give your casserole a vibrant color, crisp texture, and fresh taste. Canned green beans, on the other hand, tend to be softer and have a less vibrant appearance. Fresh is definitely the way to go for the ultimate green bean casserole experience.

Choosing the Right Mushrooms

While white button and cremini mushrooms are popular choices for this casserole, you can experiment with other varieties as well. Shiitake mushrooms add a more intense flavor, while portobello mushrooms provide a meaty texture. Feel free to mix and match for a unique twist on the classic recipe.

Cream Sauce Consistency

When making the cream sauce, aim for a thick and velvety consistency. If the sauce appears too thin, continue to simmer it until it reaches the desired thickness. On the other hand, if the sauce becomes too thick, you can add a splash of milk or broth to achieve the right consistency.

Seasoning the Dish

Remember to taste the casserole as you go and adjust the seasoning to your preference. Add more salt, pepper, or sauces if needed. This way, you can ensure the flavors are perfectly balanced and tailored to your liking.

Crispiness of French Fried Onions

To ensure the French fried onions stay crispy and golden, add them to the casserole during the last few minutes of baking. This will prevent them from becoming overly browned or soggy. The crispy onions add a delightful texture contrast to the creamy casserole.

BA’s Ultimate Green Bean Casserole is already a delicious dish on its own, but if you’re feeling adventurous, here are some variations to consider:

Adding Bacon

For a savory twist, add cooked and crumbled bacon to the casserole. The smoky flavor of the bacon pairs beautifully with the creamy green bean mixture.

Using Different Cheeses

While the classic recipe doesn’t call for cheese, you can incorporate your favorite cheese for an extra layer of decadence. Cheddar, Swiss, or Gruyere are excellent choices that melt beautifully and add a rich, cheesy flavor to the casserole.

Incorporating Other Vegetables

Though green beans are the star of this casserole, don’t be afraid to add other vegetables to the mix. Chopped bell peppers, carrots, or even peas can add vibrant colors and additional nutrients to the dish.

Making it Vegan

To make a vegan version of BA’s Ultimate Green Bean Casserole, it’s easy to make a few substitutions. Replace butter with a plant-based margarine, milk with a non-dairy milk like almond or oat milk, and chicken broth with vegetable broth. Ensure the French fried onions are also vegan-friendly or make your own using a vegan recipe.
