Bake the Potatoes : Preheat your oven to 400°F (204°C). Scrub the potatoes and pierce each several times with a fork. Place them directly on the oven rack and bake for 50-60 minutes, or until tender when pierced with a knife.
Cook the Chicken : While the potatoes bake, season the chicken breasts with the ranch seasoning mix. In a skillet over medium heat, cook the chicken for 6-8 minutes per side, or until fully cooked. Remove from the skillet, shred with two forks, and set aside.
Make the Filling : In a large bowl, combine the shredded chicken, cream cheese, diced bacon, and grated cheddar cheese. Mix until well combined.
Assemble the Potatoes : Once the potatoes are baked, remove them from the oven and allow them to cool slightly. Slice each potato lengthwise and gently fluff the interior with a fork. Spoon the crack chicken mixture generously into each potato.
Bake Again : Place the stuffed potatoes on a baking sheet. Return them to the oven and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
Add Toppings and Serve : Top each stuffed potato with extra bacon, chopped chives, ranch dressing drizzle, or blue cheese crumbles, if desired. Serve warm and enjoy!
