Ingredients

For the caramelized onions:

  • 1 Tablespoon olive oil
  • 1 medium sweet onion Vidalia, Maui, etc., chopped (about 1 1/2 cups)
  • 1 Tablespoon balsamic vinegar
  • 1 Tablespoon water

For the potatoes:

  • 2 pounds white potatoes peeled and cut into about 1 inch chunks
  • 1 cup buttermilk or 1/2 cup plain Greek yogurt and 1/2 cup milk, plus additional if needed
  • 1/2 cup grated parmesan cheese
  • 1/2 teaspoon salt or to taste
  • 1/8 teaspoon black pepper or to taste

Instructions

For the caramelized onions (can be made ahead, and kept in the fridge):

  • Heat olive oil in a pan over medium heat, and add onions.
  • Cook, stirring occasionally, until golden brown, about 15-20 minutes. You may have to lower the heat a little as they start to brown.
  • Add balsamic vinegar and water, cover and lower heat. Cook until soft and sticky. Set aside until potatoes are ready.

For the potatoes:

  • Cover potatoes in a pot with water, and bring to a boil.
  • Cook for about 15 minutes, or until potatoes are fork tender. Drain.
  • Add the buttermilk (or yogurt and milk) and mash with a hand potato masher. I like to leave it a little chunky. Add additional milk if needed to achieve desired texture.
  • Stir in the reserved caramelized onions, parmesan, salt, and pepper.
