  • sea salt to taste
  • 1 tsp. baking soda
  • 6 slices no sugar added uncured bacon
  • 1/2  finely chopped sweet onion

  • 1/4 cup heavy cream
  • 1 &1/2 C 6 oz. shredded Gruyère cheese
  • tsp.  fresh thyme leaves -or- 1 tsp. dried
  • 1 tsp. freshly ground black pepper

for the keto breadcrumb topping:

    Mix together:

    • 1/4 C pork rind breadcrumbs process plain pork rinds in the food processor until they resemble fine breadcrumbs 
    • 1/4 C grated parmesan cheese 


    • Preheat oven to 350º F. Grease a 9" square gratin dish with butter. 
    • Bring a large pot of water to a boil, salt with 2 tsp. sea salt and baking soda (will keep the beans bright green) add haricot vert. Boil for 3 minutes. Meanwhile, prepare an ice bath in a large bowl. After beans have boiled for 3 minutes, transfer to the ice bath to stop the cooking. Drain on a kitchen towel. and set aside. 
    • Heat a large 12" heavy skillet (I use cast iron) over medium heat and add bacon. Cook until crisp, about 10 to 12 minutes. Remove. Crumble when cooled. 
    • Add onions to hot pan & cook in the bacon drippings stirring occasionally until they begin to soften 2 to 3 minutes. Add mushrooms & 1/2 tsp sea salt and cook, stirring, until the mushrooms begin to release their juice and they are tender about 8 minutes. 
    • Add crème fraîche, cream, & Gruyère, thyme, & black pepper. Stir until combined and melted. Add green beans, and bacon. Mix with a big spoon until everything is mixed together. Taste for seasonings and adjust to your preference. Transfer green bean mixture to the baking dish.
    • Sprinkle keto breadcrumbs evenly over the top of casserole.
    • Bake casserole uncovered for 20 minutes, or until the keto breadcrumbs are golden brown and the tips of the beans are just starting to brown and it is warmed through. 
    • Serve immediately.
