This vegan green bean casserole is so classic and delicious that you can serve it to everyone! Suitable for anyone who avoids dairy.
Heat up a cast iron pan to medium heat. Add the oil. Once the oil is hot, add the mushrooms and toss and cook them until they get soft and 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.
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 and the edges are bubbly, about 25 to 30 minutes.
