Preheat your oven to 400°F (200°C).
- Wash and scrub the russet potatoes thoroughly. Pat them dry with a towel.
- Using a fork, poke a few holes in each potato to allow steam to escape during baking.
- Rub the potatoes with olive oil, then sprinkle with salt and pepper.
- Place the potatoes directly on the oven rack or on a baking sheet lined with parchment paper.
- Roast the potatoes for 45-60 minutes, or until the skin is crispy and the inside is soft when pierced with a fork.
- Once the potatoes are done, remove them from the oven and let them cool for a few minutes.
- Slice the potatoes open lengthwise and fluff the insides with a fork.
- Top each potato with a dollop of sour cream and a generous sprinkle of fresh chives.
- Optionally, add a pat of butter on top for extra richness.
