Instructions

  1. 1

    Peel the onions, cut them in half from root to tip, and slice them thinly into half-moons.

  2. 2

    Melt the butter with the olive oil in a large heavy pot over medium heat. Add the sliced onions, salt, and sugar, and stir to coat.

  3. 3

    Cook the onions, stirring occasionally, for 45 minutes until they are deep golden brown and caramelized. Reduce the heat if they begin to scorch.
