How to Make Dairy Free Green Bean Casserole
Preheat your oven to 400 °F. Fill a large pot with water and bring it to a rolling boil. Once boiling, add the whole or halved green beans and simmer for about 5 minutes until slightly tender. Quickly transfer them to an ice bath to stop the cooking process. Drain and set aside.
Saut the mushrooms in a large skillet over medium heat. Add the vegan butter (or neutral oil), seasoning them lightly with salt and pepper. Cook for about 5 minutes until they re tender, then stir in the minced garlic and cook for an additional minute until fragrant.
Create the creamy sauce by stirring in the flour, making sure to coat the mushrooms well. Gradually stream in the vegetable broth while stirring continuously, bringing the mixture to a gentle simmer until it thickens.
Reduce the heat to low and stir in the dairy-free milk. Let it cook for approximately 5 minutes or until you reach your desired consistency. Taste your sauce and adjust the seasoning by adding more salt or pepper as needed.
Combine the cooked green beans with the creamy mushroom sauce, ensuring that they are evenly coated and all flavors are melded together.
Assemble your casserole by transferring the mixture to a greased 9 13 baking dish. Top generously with crispy fried onions, then bake for about 15 minutes, or until the top is golden and bubbling. Serve warm and enjoy!
Optional: Garnish with fresh herbs for a pop of color and flavor.
