Vegan Green Bean Casserole

Preheat oven to 375°F. Heat oil in a large pot over medium-high heat. Add mushrooms and shallots. Cook, stirring frequently, until the mushrooms have released their liquid, 4 to 6 minutes.

Add green beans and broth and bring to a boil. Whisk 3/4 cup almond milk and flour together in a medium bowl. Add to the green bean mixture and cook, stirring, until bubbling and thickened, 2 to 3 minutes. If the sauce seems too thick, add an additional 1/4 cup almond milk. Stir in soy sauce, pepper and salt. Transfer the mixture to a 9-by-13-inch baking dish.

Sprinkle french-fried onions over the top of the casserole. Bake until bubbling and the onions are golden brown, 20 to 25 minutes.
