A delicious dish made of thinly sliced potatoes that soak up an amazingly rich creamy dairy-free sauce seasoned with garlic, shallots, thyme, and nutmeg.


  • 3.25- 3.5 pounds yellow potatoes, ( sliced thin, 1/8 in. thick)
  • 1 Tbs minced garlic, ( this was 4 cloves for me)
  • ¾ cup diced shallots, ( this was 2 larger shallots for me)
  • 2 tsp olive oil
  • 1 14 ounce can of coconut cream, (without preservatives in it, like Savoy)
  • 1 cup almond milk
  • 1/2 tsp salt
  • 1/4 tsp ground black pepper
  • 1/4 tsp ground nutmeg
  • ½ tsp fresh thyme, (and more to put on top)
  • 1/2 cup organic chicken bone broth
  • 2 Tbs tapioca flour


  • Grease a large baking dish. Preheat oven to 350 degrees Fahrenheit.
  • Put 2 tsp of olive oil into a sauce pan and heat over medium heat. Put the diced shallots and minced garlic into the pan, mix into the olive oil with a spatula, and cook for 3-4 minutes.
  • Add the almond milk, coconut cream, salt, pepper, ground nutmeg, and fresh thyme to the pan. Mix, and let the mixture boil for 10 minutes.
  • Add the organic chicken bone broth and the tapioca flour to the pan and whisk ( make sure the tapioca flour chunks dissolve).
  • Let the mixture boil for 5 minutes, while whisking every so often. Remove from heat, whisk, and set the pan aside.
  • Put 1/3 of the sliced potatoes into the pan, slightly overlapping each other. Top with 1/3 the sauce, and evenly spread it out using a spatula. Repeat this step two more times. Top with a few branches of fresh thyme. 
  • Cover the pan with aluminum foil and bake for 75 minutes. ( Note: check to see if the potatoes are ready around the 60 minutes mark. Make sure a knife can easily slide through all the layers of potatoes and hit the bottom. If not, cook for longer. Mine took 75 minutes)
  • Remove the aluminum foil, and the thyme branches. Broil for 5 minutes, until golden brown.
  • Sprinkle with sea salt and pepper, serve.
