Description

Tender chunks of baked potato, salty bacon, cheddar cheese in a rich sour cream sauce baked hot and bubbly. Twice Baked Potato Casserole is your favorite potatoes made easy!


Ingredients

  • 6 large Yukon gold potatoes
  • 1 tablespoon olive oil
  • Kosher salt
  • Ground black pepper
  • 6 slices thick bacon, cooked, crumbled and divided (about 3/4 cup)
  • 1 and 1/2 cups sour cream
  • 1/4 cup unsalted butter, melted and slightly cooled
  • 1 teaspoon garlic salt
  • 2 cups shredded sharp cheddar cheese, divided
  • Minced chives, for garnishing


Instructions

  1. Preheat oven to 400°F. Line a rimmed sheet pan with foil and spray with nonstick cooking spray.
  2. Wash and then cut the potatoes into bite-sized pieces. Pat the potato chunks dry.
  3. Place the potato chunks on the prepared sheet pan and toss with 1 tablespoon olive oil. Spread into an even layer and sprinkle generously with salt and pepper.
  4. Bake for 40-45 minutes or until golden brown and starting to crisp all over, stirring occasionally.
  5. Meanwhile, cook bacon until crispy. Let cool and then crumble into bits. Reserve 2 tablespoons of the crumbled bacon to garnish the casserole with after it bakes.
  6. Remove the potatoes from the oven and reduce the oven temperature to 350°F. Spray an 8 or 9-inch square baking dish with nonstick cooking spray.
  7. Add the sour cream, melted butter and garlic salt to a large mixing bowl and whisk to combine well.
  8. Transfer the baked potato chunks to the mixing bowl and stir to coat the potatoes well in the sour cream mixture.
  9. Fold in 1 and 1/2 cups of the shredded cheddar cheese and the crumbled bacon until well distributed.
  10. Transfer the potato mixture to the prepared baking dish.
  11. Sprinkle the remaining 1/2 cup shredded cheese over the potatoes in the baking dish.
  12. Bake for 20-25 minutes or until cheese is bubbling and start to brown in spots on top.
  13. Serve garnished with reserved bacon bits and minced chives.
