Description
This Vegan Green Bean Casserole makes the perfect side dish to any meal but of course is a go-to recipe for Thanksgiving! This gluten-free casserole is simple to make, with a homemade, dairy-free creamy mushroom roux (no canned cream of mushroom soup!) You have the option to make your own crispy fried onions, or you can use gluten-free store-bought crispy fried onions.
Ingredients
- 24 oz cut green beans, steam in bag frozen
- salt & pepper to taste
- Crispy French Fried Onions (I used Kroger Simple Truth brand)
Mushroom Roux
- 3 tablespoons plant butter or olive oil
- 1 tablespoon minced garlic
- 3 tablespoons tapioca flour/starch
- 2 cups plant milk (I use soy, oat, or coconut milk)
- 1 Not-Chick’n Bouillon Cube (from Edward & Sons- linked below)
- 1 teaspoon gluten-free soy sauce
- 1 (4 ounce) can mushrooms, chopped
Crispy Baked Onions (optional if not using store bought)
- 2 large sweet onions, sliced
- 2 tablespoons olive oil
- 1/4 cup gluten-free quick oats
- 1/4 cup almond flour
- 1 teaspoon salt
Instructions
Preheat the oven to 450 degrees F. If making your own crispy baked onions, do that first. Slice your onion into strips and then place them in a large bowl. Add the olive oil, oats, almond flour, and salt to the bowl and toss to coat the onions. Place the onions on a parchment-lined baking sheet and bake in the oven for 25 minutes, tossing halfway through.
Reduce the oven temperature to 350 degrees F. To make the creamy mushroom roux, add 3 tablespoons of plant butter or alternatively olive oil in a large skillet over medium heat. Whisk in the minced garlic and saute until it starts to turn golden, then whisk in the bouillon cube and tapioca flour to create a “paste”. Whisk in the plant milk and soy sauce. Add the mushrooms. After a few minutes reduce the heat to low and let it simmer until it thickens. Your “cream of mushroom soup” is done!
Steam the green beans in the bag for 3-4 minutes each bag, then place them in a large bowl. If you prefer to blanch your green beans, that's a simple added step here.
Pour the mushroom roux over top of the mushrooms and stir to coat all the mushrooms with the roux. Spoon the coated mushrooms in a lightly oiled casserole dish and bake for 20 minutes. Add the crispy fried onions and bake an additional 10 minutes. Let the green beans set up about 10 minutes before serving.
