How to make vegan green bean casserole

First gather your ingredients.

Ingredients

For tastiest results, always use the best quality ingredients you have access to.

To make this vegan green bean casserole recipe, you will need the following ingredients:

• canned green beans
• avocado oil
• sliced fresh mushrooms
• vegan butter
• all purpose flour
• vegetable stock
• unsweet soy milk (I like Westsoy brand), or other unsweetened plant based milk
• garlic salt (you can sub half salt, half garlic powder)
• black pepper
• french-fried onions

I used regular green beans, but feel free to use French cut, if you prefer.

I recommend unsweetened soy milk for this recipe; however, if you need to sub, just be sure it is unsweetened and unflavored (no vanilla milk, lol).

If you are omnivore, you can opt to substitute milk, butter and stock/ broth of your choice.

Making vegan green bean casserole

The cooking process involves several steps. First, preheat the oven to 350 degrees F. Heat up a cast iron pan (or large saucepan) to medium heat. Add the oil. Once the oil is hot, add the mushrooms and toss and cook them until they get soft and golden brown, about 7 minutes.

Remove and set aside. Turn the heat down to medium-low heat, then add the butter to the pan. Once the butter has melted, whisk in the flour to make a roux.

Add the stock and milk and whisk over low heat for a minute or 2 to remove any lumps. Stir in the garlic salt and pepper.

Add the cooked mushrooms back to the creamy sauce in the pan along with the green beans and season everything with salt and pepper to taste.

If you are not using an oven-safe pan, you will need to transfer the green bean mixture into a baking dish. Otherwise, remove the pan from the heat and top it with the crispy onions in an even layer.

Bake in the center rack of the oven at 350 degrees until the onions are golden brown and the edges are bubbly, about 25 to 30 minutes.

Remove, let cool and serve warm. I hope y’all enjoy this homemade green bean casserole recipe! Be sure and let me know if you try it!
