Green Bean Casserole


  • 2 lbs. Green Beans, steamed
  • 1 Tbsp. Butter
  • 1 Tbsp. Olive Oil
  • 1 cup chopped Sweet Onion
  • 4 cloves Garlic, grated
  • 8 oz. Cremini Mushrooms, half chopped and half sliced
  • ¾ cup Mushroom or Vegetable Broth
  • 1 cup Cashew Milk
  • ¼ cup Full Fat Coconut Milk
  • 2 Tbsp. Tahini
  • ½ tsp. Mustard Powder
  • 1 Tbsp. Coconut Aminos (or Wheat-Free Tamari)
  • ¼-½ tsp. Salt (will depend on the type of broth you use)
  • ½ tsp. Black Pepper
  • 1 tsp. Tapioca Starch
  • 1 large Yellow onion, thinly sliced
  • 1/2 cup Almond Flour
  • 2 Tbsp. Tapioca Starch
  • 1/2 tsp. Garlic Powder
  • ¼-1/2 tsp. Salt
  • Pinch of Black Pepper


  • Step 1

    Preheat your oven to 400 degrees Fahrenheit.

  • Step 2

    Thinly slice the onion and place them in a bowl. Pour the coconut milk and lemon juice in the bowl and mix. Let the onions soak for about 30 minutes.

  • Step 3

    Combine the almond flour, tapioca starch, garlic powder, salt and pepper in a dish. In batches, dip the soaked onions into the almond flour mixture to coat them, then carefully place them onto a parchment-covered sheet pan. Bake for 10-15 minutes on both sides, or until the onions and browned and crispy.

  • Step 4

    While the onions are baking, steam the green beans until they are just tender, but still a little crisp and set aside. Heat the butter and olive oil in a large pan over medium Heat. Once hot, add the onion and brown for 3-5 minutes.

  • Step 5

    Add in the garlic and mushrooms and saute for 1-2 minutes. Add the broth and allow the mixture to come to a simmer. In a bowl, whisk together the cashew milk, coconut milk, tahini, mustard powder and coconut aminos. Pour the mixture into the pan and whisk together until the mixture begins to bubble. Ladle ¼ cup of the liquid into a bowl and whisk in the tapioca starch to form a slurry.

  • Step 6

    Pour the steamed green beans into the pan with a pinch of salt and pepper and cook for 1-2 minutes, stirring occasionally. Pour the slurry into the pan and saute with a wooden spoon until the sauce begins to thicken. Once the mixture begins to thicken, remove the pan from the heat. Mix in half of the crispy bean beans.

  • Step 7

    Lower the oven to 375 degrees. Lightly grease a baking dish and pour the green bean mixture into it. Top the casserole with the remaining crispy onions. Bake the green bean casserole for 15-20 minutes, or until it is browned and bubbling.
