Servings: 8
Ingredients
For the Casserole
- 1.5 lbs. fresh green beans
- 1 tablespoon olive oil
- 8 oz. bella mushrooms chopped
- 1/8 teaspoon salt
- 1/2 medium white onion minced
- 1 tablespoon minced garlic
- 1.5 cups fried onions store-bought (like French's) or homemade, divided
For the Roux
- 1/4 cup olive oil
- 1/2 cup white whole wheat flour
- 2 cups unsweetened almond milk
- 1/2 tablespoon Worcestershire sauce
- 1/2 teaspoon salt
- 1/4 teaspoon ground pepper
- 1 teaspoon garlic powder
- 1 tablespoon minced fresh thyme
- 3/4 cup vegetable broth
Instructions
- Preheat the oven to 375ºF. Generously spray a 9x13-inch casserole dish with nonstick cooking. Set aside while you prepare the green beans.
- Wash the green beans and pat them dry. Use a kitchen scissors (or sharp knife) to snip the ends off. Place the trimmed green beans into the prepared casserole dish. Set aside.
- Heat the olive oil in a large frying pan over medium/high heat. Add the mushrooms and salt and sauté for 3-5 minutes. Add the onion and garlic and continue to sauté for another 3 minutes. Remove the pan from the heat and set aside.
- Make the roux. Heating the olive oil in a medium saucepan over medium/high heat. When the oil is fragrant, add the flour and whisk until a crumble or paste forms. While continuing to whisk, slowly pour in the almond milk. Whisk over medium heat until the mixture begins to thicken, about 3-5 minutes.
- When thick, remove the saucepan from heat and whisk in the Worcestershire sauce, salt, pepper, garlic powder, fresh thyme, and vegetable broth.
- Add the mushroom mixture into the roux and mix to combine to create a sauce.
- Pour the sauce on top of the green bean in the casserole dish and mix to combine.
- Cover the casserole dish with foil and bake for 40-45 minutes, stirring the beans every 15 minutes. Bake until the green beans are cooked.
- Once the green beans are fully cooked, mix in 1/2 cup of fried onions. Then, top the casserole with the remaining 1 cup of fried onions and serve.
