Start by preheating your oven to 400°F. Scrub the potatoes clean, dry them well, and rub them lightly with olive oil. Sprinkle with salt and pepper, then bake directly on a lined baking sheet for about 50–60 minutes until tender inside.
While the potatoes bake, add softened cream cheese to a bowl. Mix in the ranch seasoning until smooth and creamy. Fold in the shredded chicken, bacon, green onions, and most of the shredded cheese, reserving some for topping.
Once baked, let the potatoes cool slightly so they’re easy to handle. Slice them lengthwise and gently scoop out most of the fluffy interior, leaving a sturdy shell. Add the potato flesh to the chicken mixture and stir until combined.
Spoon the crack chicken mixture back into the potato skins, mounding it slightly. Sprinkle the tops with the remaining shredded cheese. This extra layer melts beautifully and adds a golden finish.
Return the stuffed potatoes to the oven and bake for another 10–15 minutes. Once the cheese is melted and bubbly, remove them and let them rest briefly before serving.
