Ingredients

  • 16 oz frozen green beans
  • ¾ cup sliced mushrooms
  • 4 tablespoon vegetable stock
  • 2 tablespoon gluten-free flour
  • 1 ½ cups unsweetened soy milk
  • 1 tablespoon dijon mustard
  • ½ tsp salt
  • ¼ teaspoon sage
  • ¼ teaspoon oregano
  • ¼ teaspoon black pepper
  • 1 small white onion finely sliced
  • ¼ cup gluten free Panko breadcrumbs

Instructions

  • Preheat oven to 375 F. Add green beans, then mushrooms to casserole dish. Set aside.
  • In a saucepan on low heat, add 2 tbsps of vegetable stock. Stir in the gluten-free flour until a paste is formed. Add soy milk, dijon mustard, salt, pepper, sage, and oregano. Whisk together. Continue to whisk until sauce begins to thicken. Remove from heat, and set aside.

  • Bake for 35 minutes. Remove and allow to cool for 10 minutes before serving.

Notes

Tips for Making Vegan Green Bean Casserole
  • Nutrition facts are estimated.
  • Store it in an airtight container in the refrigerator for 3-4 days.
  • Reheat in the oven or microwave.
  • It will freeze for 2-3 months.
  • There is no need to defrost the green beans before cooking.
  • Buy pre-sliced mushrooms to save yourself a step.
  • Be sure to use unsweetened plain soy milk, with no vanilla or sugar added. If you can't find unsweetened soy milk, use unsweetened coconut or cashew milk.
  • Since this recipe doesn't use butter to create a roux, it's important to whisk continuously so that the flour incorporates with the milk.
