Ingredients
  

  • Olive oil or nonstick cooking spray
  • 8 medium potatoes scrubbed and dried
  • 1/2 pound bacon
  • 1/2 cup butter at room temperature, cut into cubes
  • 1 cup sour cream at room temperature
  • 1 cup whole milk at room temperature
  • 1 1/2 cups cheddar cheese shredded and divided
  • 2 green onions sliced and divided
  • Salt and pepper to taste

Instructions
 

  • Preheat the oven to 400°F. Prepare a 9x13-inch baking dish with a coating of olive oil or nonstick cooking spray.
  • Poke the clean potatoes with a fork about 6-8 times each for even venting. Arrange them in a single layer on a baking tray with a little space between them. Bake for 45-60 minutes, until fork-tender with browned skins.

  • Fry the bacon in a nonstick skillet over medium heat until crispy, turning occasionally, about 10 minutes. Drain off excess fat, then set aside to cool. Chop roughly.

  • Remove the cooked potatoes from the oven and allow them to cool for 30-45 minutes. Once cool enough to handle, peel the skins (if desired) and cut into chunks.

  • In a large mixing bowl, add the potato chunks, half the chopped bacon, the butter, milk, sour cream, 1 cup of the cheddar cheese, the salt and pepper, and about 3/4 of the sliced green onion. Stir until just combined, lightly mashing the potatoes, but avoid overmixing, which can lead to a gummy texture.
