Step-by-Step Cooking Instructions

Preparing the Mashed Potatoes:

1. Boil the Potatoes: Place the chopped potatoes in a large pot and cover with cold water. Add a pinch of salt and bring to a boil. Cook until the potatoes are tender, about 15-20 minutes.

Assembling the Casserole:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Layer the Casserole: Spread the mashed potato mixture evenly in a greased baking dish. Sprinkle the remaining 1 cup of shredded cheddar cheese over the top.

Baking the Casserole:
