Preheat your oven to 350°F (175°C).

Boil the potatoes with skins on until tender.

Allow them to cool slightly, then peel and shred them into a large bowl.

Add the sour cream, diced green onions, grated sharp cheddar cheese, salt, and pepper to the bowl with the shredded potatoes.

Mix gently to combine.

Transfer the mixture to a greased 13x9x2-inch casserole dish.

Bake in the preheated oven for 40 minutes or until the top is golden and bubbly.

Serve hot as a delightful side dish alongside your favorite main course.

Enjoy the creamy, cheesy goodness of this potato bake!
