Ingredients

  • 1 pound yellow onions (about 3), sliced thin
  • 3 Tablespoons unsalted butter plus more for buttering the dish
  • 1 Tablespoon fresh thyme leaves coarsely chopped
  • 1 teaspoon kosher salt divided
  • 1/2 teaspoon black pepper divided
  • 1/8 teaspoon nutmeg
  • 4 large eggs
  • 1/4 cup whole milk
  • 3 Tablespoons heavy cream
  • 1 Tablespoon chives chopped

Instructions

  • Preheat oven to 425*
  • Butter the bottom and sides of a 10" baking dish.
  • Slice onions in half and then slice thinly.
  • In a large unheated skillet, combine the onions, butter, thyme, 3/4 teaspoon salt, 1/4 teaspoon pepper and a pinch of nutmeg. Cover pan and cook until the onions are soft, but not caramelized or brown, stirring occasionally, about 12 minutes.
  • Whisk the eggs in a medium-sized bowl with milk, cream, and remaining salt, pepper and nutmeg, until eggs are blended. Add chopped chives.
  • Spread the onions out in the buttered baking dish. Pour the egg mixture over the onions.
  • Bake until the top is deep golden brown and the custard is firm, about 30 minutes.
  • Let it sit for about 5 minutes to firm up. Serve warm.

Notes

  • For appetizer size portions, bake in an 8" by 8" square pan and cut into 16 portions.
