Ingredients

  • 2 lbs. Yukon Gold Potatoes peeled and sliced thinly
  • 1 Tbsp. unsalted butter
  • 1 Tbsp. garlic freshly minced
  • cups heavy whipping cream
  • ½ lb. Gruyere cheese shredded (about 1½ cups)
  • 3 Tbsp. unsalted butter cut into little cubes
  • 2 tsp. fresh thyme leaves (optional)
  • 1 tsp. kosher salt
  • ½ tsp. freshly cracked black pepper

Instructions

  • Preheat your oven to 350°F.
  • Peel yukon gold potatoes. I find a Y-peeler works best. Carefully cut them into thin slices using a sharp knife and a clean cutting board. You may also use a food processor with a slicing attachment or a mandoline with a finger guard.
    2 lbs. Yukon Gold Potatoes
  • Place your potato slices in cold water for about 5 minutes. Give them a couple of tosses in the water, then drain the water. This will reduce excess starch in addition to cleaning up the potatoes.
  • Heat an oven-safe skillet on the stove and melt butter in it. A 10-inch skillet with 2-inch sides or similar works best.
    1 Tbsp. unsalted butter
  • Once the butter melts, remove the skillet from the heat and add minced garlic. Stir the garlic around to coat it with the butter.
    1 Tbsp. garlic
  • Spread half of the sliced potatoes in the bottom of the skillet. Top with heavy cream, Gruyere cheese, salt, pepper, half of your cubed butter, and thyme (if using).
    1½ cups heavy whipping cream, ½ lb. Gruyere cheese, 3 Tbsp. unsalted butter, 2 tsp. fresh thyme leaves
  • For the next layer, add the remaining potatoes, cream, salt, pepper, butter, and thyme. Finish with remaining cheese on top.
    1 tsp. kosher salt, ½ tsp. freshly cracked black pepper
  • Cover with aluminum foil or a pan lid. Bake for 1 hour.
  • Remove the foil and use a fork to check if the potatoes are tender. They are best when fork-tender but still with a little firmness to them. However, you can bake them a bit longer for softer potatoes, if you prefer them softer.
  • Once the potatoes are tender to your liking, remove the foil and continue to bake the gluten free au gratin potatoes for 15-20 minutes, or until the top develops a beautiful golden brown crust.
  • Allow the dish to rest for 10 minutes after removing from the oven. Serve, and enjoy!

Notes

  • Use Yukon Gold potatoes for best results. Russet potatoes work as a substitute.
  • You can use Swiss or Cheddar instead of Gruyere cheese if you prefer.
  • Use fresh garlic and thyme to get the most flavor out of this dish. If you’re sensitive to garlic, reduce to ½ tsp. or rub the garlic on the inside of the baking dish instead of cooking with it.
  • Use a large skillet so there's no chance the dish will overflow in your oven.
