Ingredients

The following ingredients have 2 Servings
  • 2 tablespoons olive oil
  • 2 pounds red onions (thinly sliced)
  • 1/4 cup packed brown sugar
  • 1 teaspoon sea salt
  • 3/4 teaspoon red pepper flakes
  • 2 cups dry red wine

Instruction

  • In a large skillet over medium heat, warm the olive oil. Add the onions and cook, stirring occasionally, until softened, about 15 minutes.
  • Sprinkle the onions with the brown sugar, salt, and red pepper flakes, and stir. Add the red wine, bring to a boil, and then reduce the heat to maintain a steady simmer.
  • Continue cooking, stirring occasionally, until most of the liquid has evaporated and the onions are collapsed and caramelized, 40 to 60 minutes more. Taste and adjust the seasoning as needed.
  • Use immediately or cover and refrigerate for up to 10 days, or freezer for up to 2 months.
