Healthy Green Bean Casserole


Traditional Green Bean Casserole just got a makeover! This Healthy Green Bean Casserole is vegan and gluten free and filled with nourishing ingredients.


Units Scale
  • 2 onions, sliced
  • 2 tablespoon avocado oil, divided (or oil of choice for high heat)
  • 1 pound green beans, trimmed and cut into pieces
  • 1 pound sliced white mushrooms
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper
  • 56 garlic cloves, chopped
  • 1 (15 ounce) can great northern beans, drained and rinsed
  • 1/2 cup vegetable broth
  • 1 tablespoon low-sodium tamari
  • 2 teaspoons miso (optional)
  • 1/2 cup almonds, chopped


  1. Preheat your oven to 425 degrees.
  2. Place your sliced onions on a parchment-paper lined baking sheet and sprinkle with 1 tablespoons avocado oil and salt and black pepper. Toss to coat.
  3. Roast the onions in the oven until they are browned and crisped to your liking, 25-35 minutes. Stir frequently during the cooking time.
  4. Meanwhile, boil a pot of water. Add your green beans to the pot and boil 5 minutes. Remove from water and set aside in a small bowl.
  5. Heat 1 tablespoon avocado over medium high heat. Add the mushrooms and cook until they are cooked down and the water is mostly evaporated, about 6-8 minutes.
  6. Add the garlic and cook another minute or two. Remove from heat.
  7. Transfer 1 1/2 cups of the mushroom mixture to a blender. Add the beans, vegetable broth, soy sauce, and miso. Blend until you have a smooth and creamy mixture.
  8. Add the remaining mushrooms to the mixture.
  9. Mix together the green beans and mushroom mixture and put it in a 1 1/2 quart baking dish. Top with the onions.
  10. *Each of the three components can be done ahead of time. Assemble just before baking.*
  11. Reduce the heat in the oven to 350 degrees. Bake the casserole for 20 minutes (longer if you have prepared ahead of time and the ingredients are cold). Add the chopped almonds and bake an additional 5 minutes. Enjoy!


Ingredient Note: If you don’t need this to be vegetarian, chicken broth will work also.
