Cheesy Mashed Potato Casserole

To make cheesy mashed potato casserole, start by peeling and cutting 6 potatoes into chunks. Boil them in salted water until tender, about 15 minutes. Drain and return the potatoes to the pot, then mash them with 4 tablespoons of butter, 0.5 cup of milk, 1 teaspoon of salt, and 0.5 teaspoon of pepper until smooth. Stir in 1 cup of shredded cheddar cheese. Preheat your oven to 375°F (190°C), transfer the mixture to a baking dish, and top with the remaining cheddar and 1 cup of shredded mozzarella cheese. Bake for 20-25 minutes until golden and bubbly.
