Ingredients Notes For Twice Baked Potato Casserole:

  • Potatoes: Russet potatoes are ideal for their fluffy texture when baked.
  • Sour Cream and Butter: For creaminess and richness in the potato mixture.
  • Cheese: Sharp cheddar cheese adds depth of flavor; you can mix in other varieties like Gouda or Monterey Jack for more complexity.
  • Bacon: Cooked and crumbled bacon provides a smoky, savory element.
  • Green Onions: For a pop of color and freshness.
  • Seasonings: Salt, pepper, and garlic powder enhance the overall taste.
  • Potato Chips: Choose your favorite brand and flavor of potato chips for the crust, adding an extra layer of crunch and flavor.

Recipe Steps:

  1. Prep the Potatoes: Bake the potatoes until tender, then scoop out the flesh and mash with sour cream, butter, salt, pepper, and garlic powder.
  2. Mix in the Goodies: Stir in most of the shredded cheese, bacon (reserve some for topping), and chopped green onions into the mashed potato mixture.
  3. Assemble the Casserole: Transfer the potato mixture to a greased baking dish. Smooth the top with a spatula.
  4. Add the Potato Chip Crust: Crush the potato chips lightly (not too fine) and mix with the remaining cheese. Sprinkle this mixture over the top of the potato mixture.
  5. Bake: Bake in a preheated oven at 350°F (175°C) until the casserole is heated through and the potato chip crust is golden and crispy, about 15-20 minutes.
  6. Serve: Garnish with additional green onions and crumbled bacon before serving.

Storage Options:

  • Refrigerate: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven to maintain the crust’s crispiness.
  • Freeze: It’s best enjoyed fresh, as the potato chip crust may not retain its texture upon freezing and reheating.
