Preheat the oven to 400 degrees. Coat a baking dish with olive oil cooking spray.
Place the potatoes into the baking dish and drizzle with olive oil then season with sea salt, freshly cracked pepper, and garlic powder, to taste then toss to coat evenly.
Place into the oven and roast for 20-25 minutes, or until fork-tender. Remove from the oven and let them cool for a few minutes.
Slit across the top then gently pinch each end of the potato towards the middle. Spoon a bit of sour cream on top followed by a sprinkling of chives. Serve immediately. Enjoy.
