Ingredients

  • 5 pounds red and white table potatoes, cut into 1-inch pieces
  • 3 tablespoons olive oil
  • 2 teaspoons minced garlic
  • 1 1/2 teaspoons salt, divided
  • 3/4 teaspoon ground black pepper, divided
  • 1/4 cup butter
  • 1 large onion, chopped
  • 1 tablespoon balsamic vinegar
  • Blue Cheese Dressing:
  • 3/4 cup mayonnaise
  • 1 (5-ounce) container crumbled blue cheese
  • 2 tablespoons sour cream
  • 1 1/2 teaspoons prepared horseradish
  • 1/2 teaspoon ground black pepper
  • In a small bowl, combine the mayonnaise, blue cheese, sour cream, horseradish, and pepper. Cover, and refrigerate until ready to use.
  • Yield: about 1 cup

Method

  • Preheat the oven to 450 degrees F. Line a large shallow roasting pan with nonstick aluminum foil.
  • In a large bowl, combine the potatoes, olive oil, garlic, 1 teaspoon salt, and 1/2 teaspoon pepper, tossing gently to coat. Arrange the potatoes, in a single layer, on the prepared pan. Bake until potatoes are tender and lightly browned, stirring occasionally, for 35 minutes. Remove from the oven and cool.
  • In a large skillet, melt the butter over medium-low heat. Add the onions; cover and cook for 30 minutes, stirring occasionally. Uncover and add the vinegar. Stir until the vinegar evaporates, about 1 to 2 minutes.
  • In a large serving bowl, combine the potatoes, onions, remaining salt and pepper and Blue Cheese Dressing. Serve immediately, or cover and refrigerate. Bring to room temperature before serving.
