Ingredients

  • 1-2 yellow onions, peeled and thinly sliced (see notes)
  • 2 cloves garlic, minced
  • 2 tablespoons fresh thyme, leaves picked
  • 2 tablespoons salted butter
  • 1 kg (2 lb) potatoes, peeled and thinly sliced (see notes)
  • 425 ml (1½ cups) hot stock made with a stock cube, see notes

Instructions

  • Preheat the Oven: Preheat the oven to 180ºC (160ºC fan).
  • Prepare the Onions and Garlic: Peel and thinly slice the onions and mince the garlic.
  • Sauté Onions and Garlic: Melt the butter in a skillet over medium heat. Sauté the onions, garlic, and thyme until soft and translucent, about 10 minutes.
  • Prepare the Potatoes: While the onions are sautéing, peel and thinly slice the potatoes.
  • Layer the Ingredients: Grease a casserole dish (30cm x 20cm) or a 30cm skillet. Place the softened onions and potatoes in alternating layers in the dish.
  • Add the Stock: Pour the hot stock evenly over the potatoes.
  • Bake: Cover the dish with foil and bake in the preheated oven for 45 minutes.
  • Finish Baking: Remove the foil and brush the top layer of potatoes with some melted butter. Bake uncovered for an additional 15 minutes, or until the potatoes are golden on top.

Notes

  • Onion Quantity: The number of onions needed will depend on their size and the desired amount of sautéed onion between the potato layers. Typically, 2 medium onions are sufficient.
  • Stock: Ensure the stock is hot when pouring over the potatoes to promote even cooking.
