Vegan Green Bean Casserole:  Ingredients

Green beans

Green beans are the star of this vegan casserole recipe. They provide a crisp and fresh element to the dish. When choosing green beans, make sure they are fresh and free from any blemishes or signs of wilting.


Onions add a wonderful depth of flavor to the casserole. They can be diced or sliced, depending on your preference. Sauteed onions bring a sweet and caramelized taste to the dish.


Mushrooms add a savory and meaty texture to the casserole. They can be sliced or chopped, depending on your desired consistency. You can use any type of mushrooms, such as cremini, button, or shiitake, to add depth to the dish.


Garlic is a culinary staple that adds a rich and aromatic flavor to the casserole. Make sure to finely chop or mince the garlic for even distribution of flavor throughout the dish.


Flour serves as a thickening agent in the mushroom sauce. You can use all-purpose flour or a gluten-free alternative if preferred.

Vegetable broth

Vegetable broth is the base of the mushroom sauce and adds a savory flavor to the casserole. Opt for low-sodium vegetable broth to control the saltiness of the dish.

Non-dairy milk

Non-dairy milk adds creaminess to the mushroom sauce. You can choose from a variety of options like almond milk, soy milk, or oat milk. Make sure to use an unsweetened and unflavored variety to maintain the savory taste of the casserole.

Nutritional yeast

Nutritional yeast is a popular vegan ingredient that adds a cheesy and nutty flavor to the casserole. It can be found in health food stores or the bulk section of grocery stores.


Breadcrumbs serve as a crispy and crunchy topping for the casserole. You can use store-bought breadcrumbs or make your own by toasting and processing bread slices.

Salt and pepper

Salt and pepper are essential for seasoning the dish to taste. Adjust the amount according to your preference, keeping in mind the saltiness of the vegetable broth and nutritional yeast.

Vegan Green Bean Casserole:  Preparation

Cleaning and trimming the green beans

Start by cleaning the green beans under cold water to remove any dirt or debris. Trim off the ends of the beans, if necessary. Some green beans may have a stringy seam, which can be removed by gently pulling it from the tip to the stem end.

Blanching the green beans

Blanching the green beans helps to lock in their vibrant green color and ensures a tender-crisp texture. To blanch the green beans, bring a large pot of salted water to a boil. Drop the green beans into the boiling water and cook for about 2-3 minutes, until they become bright green and slightly tender. Then, drain the beans and transfer them to an ice bath to stop the cooking process. Once cooled, drain and set aside.

Making the mushroom sauce

In a large skillet, sauté the onions and garlic until translucent and fragrant. Add the mushrooms and cook until they release their moisture and become golden brown. Sprinkle the flour over the mushroom mixture and stir well to coat. Gradually pour in the vegetable broth and non-dairy milk, stirring constantly to combine. Bring the mixture to a simmer and cook until the sauce thickens. Add the nutritional yeast, salt, and pepper to taste. Set the mushroom sauce aside.

Preparing the onion topping

To make the crispy onion topping, thinly slice the onions into rings. In a separate skillet, heat oil over medium heat and add the sliced onions. Cook until they become golden brown and crispy, stirring occasionally. Transfer the crispy onions to a plate lined with paper towels to remove excess oil.

Assembling the casserole

Preheat the oven to 350°F (175°C). In a large baking dish, combine the blanched green beans with the mushroom sauce, stirring gently to coat the beans evenly. Sprinkle the breadcrumbs over the top of the casserole, followed by the crispy onion topping.

Baking the casserole

Place the assembled casserole in the preheated oven and bake for about 25-30 minutes, or until the breadcrumbs are golden brown and the casserole is bubbling. Remove from the oven and let it cool slightly before serving.

Vegan Green Bean Casserole:  Tips and Variations

Adding crispy tofu crumbles

For an extra protein boost, you can add crispy tofu crumbles to the casserole. Simply press tofu to remove excess moisture, crumble it into small pieces, and pan-fry or bake until crispy. Sprinkle the tofu crumbles over the casserole before baking.

Using different mushrooms

Experiment with different types of mushrooms to vary the flavors and textures in the casserole. For example, using a combination of cremini, shiitake, and oyster mushrooms can add depth and complexity to the dish.

Adding vegan cheese

If you want to make your casserole even more indulgent, sprinkle some vegan cheese on top before baking. Choose a melty variety like vegan cheddar or mozzarella and sprinkle it over the casserole along with the breadcrumbs.

Adding herbs and spices

To enhance the flavor profile of the casserole, consider adding herbs and spices. Fresh herbs like thyme or rosemary can add a fragrant note, while spices like paprika or cayenne pepper can add some heat and smokiness.

Making it gluten-free

To make the casserole gluten-free, substitute the all-purpose flour with a gluten-free flour blend. Additionally, ensure that the breadcrumbs used for the topping are also gluten-free, or you can use crushed gluten-free crackers as an alternative.
