Ingredients

  • 1/2 cup butter, divided
  • 3 large sweet onions, halved and thinly sliced
  • 1-1/2 teaspoons salt, divided
  • 3/4 teaspoon pepper, divided
  • 3 teaspoons minced fresh thyme or 1 teaspoon dried thyme
  • 3-1/2 pounds medium red potatoes, halved
  • 1 cup 2% milk
  • 10 slices bacon strips, cooked and crumbled
  • 1 cup shredded Gruyere or white cheddar cheese
  • Chopped fresh parsley, optional

Method

  • In a large skillet, heat 1/4 cup butter over medium-high heat. Add onions, 1/4 teaspoon salt and 1/8 teaspoon pepper; cook and stir 8-10 minutes or until softened. Reduce heat to medium-low; cook 40-50 minutes or until deep golden brown, stirring occasionally and stirring in thyme during last 5 minutes.
  • Place potatoes in a 6-qt stockpot; add water to cover. Bring to a boil. Reduce heat; cook, uncovered, 20-25 minutes or until tender. Drain; return to pan. Add milk and remaining butter, salt and pepper. Coarsely mash potatoes with a masher, leaving small chunks. Stir in bacon and onions; sprinkle with cheese. Let stand, covered, until cheese melts. If desired, sprinkle with parsley.
