  • Slow Cooker or Crock Pot



  • In a large pot, heat the olive oil until shimmering on medium heat.  Add the onion, garlic, and mushrooms, and saute on low for 8 minutes.  Transfer to a slow cooker.
  • To the same pot, fill with 4 cups water and bring to a boil.  Add the fresh green beans and cook for 5 minutes.  Beans should be a bright green color and slightly al dente.  Drain, and add beans to the slow cooker.
  • Add the rest of the ingredients to the slow cooker: coconut milk, almond milk, Worcestershire sauce, onion powder, GF breadcrumbs,  and 1 cup of the fried onions (reserve a half cup of the green beans for top of casserole later).
  • Mix and cook on high for 3-4 hours, until bubbling. Once finished, top with remaining fried onions and enjoy!
  • Optional Step - Grease a 13 x 9 casserole dish and transfer green bean mixture into dish.  Top with remaining fried onions, and broil for 5 minutes until the top begins to crisp.
