Ingredients
  

  • 5 large Russet potatoes, baked and cooled
  • 1 cup sour cream
  • 1 cup whole milk
  • 1/2 cup unsalted butter, softened
  • 2 cups shredded cheddar cheese, divided
  • 8 slices cooked bacon, crumbled
  • 1/2 teaspoon garlic powder
  • Salt and black pepper, to taste
  • 1/4 cup chopped green onions (plus extra for topping)

Instructions
 

  • Prepare the Potatoes
    Preheat oven to 350°F (175°C). Peel and cube the baked potatoes into chunks.
  • Mix the Filling
    Place potatoes in a large bowl. Add sour cream, milk, butter, garlic powder, salt, and pepper. Mix gently until creamy but still slightly chunky.
  • Add Flavor
    Stir in 1½ cups cheddar cheese, bacon, and green onions. Mix lightly to blend evenly.
  • Bake the Casserole
    Spread the mixture into a greased baking dish. Sprinkle remaining cheese on top. Bake for 25–30 minutes until hot and bubbly.
  • Garnish and Serve
    Top with extra bacon and green onions before serving. Enjoy hot.

Notes

  • Russet potatoes create the fluffiest consistency.
  • Bake potatoes ahead to save time.
  • Add cream cheese for extra richness.
  • Use thick-cut bacon for best texture.
  • Serve immediately for perfect creaminess.
