Prep the potatoes:

  • While peeling and thinly slicing potatoes, place slices in a bowl of cool water. This will keep the potatoes from browning. Drain very well and blot the potato slices before layering.

Making the sauce:

  • In a large saucepan, malt the margarine or coconut oil over medium heat. Add cornstarch to oil and whisk constantly until bubbly and well blended.

  • Layer potatoes in baking dish, overlapping potatoes and layers. Pour sauce over the potatoes. Dust lightly with paprika. Cover with foil. 
  • Bake at 350F for 30 minutes. Uncover and bake for another 60 minutes until potatoes are tender, sauce is bubbling and the edges are golden. Remove from oven and sprinkle with extra thyme. Let potatoes sit for 10 minutes, then serve. 

To freeze:

  • I freeze this in two 8”x8” pans. Affter assembeling, partially bake for the first 40 minutes, then allow to cool. Sprinkle on remaining thyme for garnish. Double wrap with heavy foil, lable and freeze.
