Ingredients
  

  • 1 tbsp olive oil
  • 3 tbsp butter, divided
  • 2 large onions, sliced
  • Splash water or broth, if needed for the onions
  • 2 tbsp chopped parsley, plus more for garnish
  • 1 tbsp thyme leaves
  • 1 tsp grated garlic
  • Fine salt and freshly ground black pepper, to taste
  • 1 tbsp Kosher salt for the potato cooking water
  • 2 pounds potatoes, Yukon Gold, cut into 1/4-inch slices
  • Butter or cooking oil spray for the baking dish

Instructions

  • In a large skillet, heat the olive oil and 2 tablespoons of butter over medium-low heat. Add the onions and cook slowly—about 20 to 30 minutes—until they’re soft and light golden but not too dark. Stir occasionally so they don’t stick or burn. If necessary, add a splash of water or broth.

  • Meanwhile, bring a pot of water and 1 tablespoon of kosher salt to a boil. Add the potato slices and cook for 3 minutes once the water returns to a boil. Drain and let them cool slightly, then add them to the onion mixture and toss gently to mix.

Lightly butter a 3-quart baking dish (9-by-13-inch) or spray it with cooking oil spray. Transfer the potato and onion mixture to the baking dish, gently pressing it down slightly to flatten. Cut the remaining 1 tablespoon of butter into small pieces and scatter it over the potatoes.
