Preheat oven to 400°F. Wash, scrub, and dry potatoes.
Piece with a fork 5 or 6 times. Rub with olive oil, and sprinkle with salt and pepper.
Place the potatoes directly on the oven rack or a baking tray. Bake for about 50-60 minutes until they’re tender when poked with a fork.
Once out of the oven, let the potatoes cool slightly. Cut them lengthwise and scoop out most of the flesh, leaving about ¼ inch behind.
Melt bacon grease or use olive oil to brush both sides of the potato shells. This layer not only adds flavor but ensures they crisp up in the oven.
Place the shells cut-side down on a baking sheet lined with parchment paper or foil. Bake at 425°F (220°C) for 8-10 minutes, then flip them over and bake for another 5-7 minutes.
Remove from oven and sprinkle with grated cheese and bacon pieces. Return to oven for 5-7 minutes, or until the cheese is melted and bubbling. Keep an eye on them at this stage so they don’t overcook.
Sprinkle with green onions and serve with ranch dressing, chipotle sour cream/Greek yogurt, or your favorite dipping sauce.
Notes
During scooping, avoid digging too deep into the potato. Leaving a thin layer of the potato flesh (about ¼ inch) gives the skin structure while still crisping beautifully in the oven. If you scoop out too much, just fill it back in. They will be covered with cheese, no one will notice!
Double-bake method: After scooping and adding oil or butter, bake the skins cut-side down first to crisp the outer layer. Then flip them up (skin-side down) to finish and caramelize the inside edges.
Leftovers: Store cooled potato skins in an airtight container for up to 3 days. Reheat in oven or air fryer for best results.
