  • 4 potatoes, scrubbed and sliced thin. I use this mandoline 
  • 3 cups cream or whole milk
  • 2 garlic cloves – chopped fine
  • 3 tablespoons butter
  • 810 sprigs of fresh thyme – tied with string in a bundle
  • 1/2 tablespoon nutmeg
  • salt and pepper to taste
  • 2 cups Gruyere cheese – shredded
  • 1 large sweet onion – thinly sliced
  • Olive oil and 1 tablespoon butter – for sauteeing 
  • balsamic vinegar 


  1. Pre-heat oven to 350F
  2. In a large deep pot add the milk, garlic, thyme bundle, nutmeg, salt, and pepper, bring to a low simmer then add the potato slices. Season with more salt and pepper, stir gently trying to get the potatoes into the milk. Simmer about 10 minutes, the cream should thicken slightly. Note – taste the cream and potatoes, you may need to add more salt. Potatoes typically need plenty of salt to really bring out their flavor.
  3. While the potatoes are cooking sautee the onions. In a deep skillet heat a drizzle of olive oil and the butter, once hot add in the sliced onions and cook over low heat, stirring occasionally until onions are very soft and translucent. Remove from heat and stir in a drizzle of balsamic vinegar.
  4. If using mini serving dishes layer in the potato slices so they are layered leaning against each other, spoon some of the thickened cream over the potato slices. Then top with onions and shredded cheese. Bake at 350F (uncovered) for about 30 minutes or until the potatoes are cooked through.
  5. If using a 9×9 baking dish, spray with non-stick spray and place in the potatoes (I don’t try to layer them neatly b/c after you add the toppings you won’t see it) and spoon over some of the thickened cream (about halfway up the baking dish). Layer on the onions and cheese, bake for about 30 minutes or until the potatoes are cooked through.
  6. Turn on the broiler for a few minutes to brown the cheese.
