Step-by-Step Cooking Instructions

Preparing the Mashed Potatoes:

- Add Cheese: Stir in 1 cup of shredded cheddar cheese until well combined.
Assembling the Casserole:
- Preheat Oven: Preheat your oven to 375°F (190°C).
- Transfer to Baking Dish: Spread the mashed potato mixture evenly in a greased 9x13-inch baking dish.
Preparing the Topping:
- Prepare Topping Mixture: In a small bowl, melt 1 tablespoon of butter. Mix in ¼ cup of panko breadcrumbs until well coated.
- Top the Casserole: Sprinkle the panko mixture evenly over the mashed potatoes. Add the ½ cup of shredded cheddar cheese, chopped chives, and crumbled bacon on top.
Baking the Casserole:
- Bake: Place the casserole in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and crispy.
- Serve: Remove from the oven and let it cool for a few minutes before serving.
