Preheat your oven to 400°F (200°C).

Wash and scrub the potatoes thoroughly. Dry them, then poke holes with a fork.

Wrap each potato in aluminum foil.

Place the wrapped potatoes on a baking sheet and bake for about 1 hour.

Carefully unwrap the potatoes and let them cool slightly. Cut each potato in half lengthwise and scoop out the insides.

In a mixing bowl, combine the scooped potato, sour cream, cheddar cheese, green onions, and butter. Season with salt and pepper.

Carefully spoon the filling back into the potato skins.

Place the filled potatoes back on the baking sheet and bake for an additional 15-20 minutes at 375°F (190°C).
