Ingredients
  

  • 6 lbs Russet Potatoes about 6 large, washed and dried
  • 2 tablespoon Vegetable Oil for brushing potatoes
  • ½ lb Bacon divided, cooked and crumbled
  • 1 stick Butter softened, ½ cup
  • 1 cup Sour Cream 8 oz, full-fat or light
  • 1 cup Milk 8 oz, any kind
  • 8 oz Cream Cheese softened
  • 2 cups Cheddar Cheese shredded, divided
  • 1 teaspoon Garlic Powder or to taste
  • 1 tablespoon Salt adjust to taste
  • 1 teaspoon Black Pepper freshly ground
  • Nonstick Cooking Spray for greasing casserole
  • 2 Green Onions thinly sliced for garnish

Method
 

  1. Preheat the oven to 400°F (200°C) and line two baking trays with parchment paper.
  2. Pierce each potato several times with a fork, brush with vegetable oil, and place on one tray. Bake until fork-tender, about 1 hour.
  3. Place bacon on the second tray and bake for 15–20 minutes until crisp. Remove and crumble once cooled.
  4. When potatoes are done, reduce oven temperature to 375°F (190°C). Allow potatoes to cool slightly.
  5. Scoop the insides of all potatoes into a large mixing bowl, leaving skins aside.
  6. Add half of the crumbled bacon, butter, sour cream, milk, cream cheese, 1 cup of cheddar cheese, garlic powder, salt, and black pepper. Mash and fold together until smooth and creamy.
  7. Grease a 9x13-inch baking dish and transfer the mashed potato mixture into it, spreading evenly.
  8. Top with remaining cheddar cheese and crumbled bacon.
  9. Bake uncovered for 25 minutes until cheese is melted and bubbly. Remove from oven and garnish with sliced green onions.
