Preheat your oven to 400°F (200°C). Scrub the potatoes clean, then prick them several times with a fork to allow steam to escape. Place the potatoes directly on the oven rack and bake for 45-60 minutes, or until tender when pierced with a fork.
If you haven’t already, prepare your buffalo chicken in a crock pot or simply mix shredded chicken with your favorite buffalo sauce in a bowl. Make sure it's well-coated and heated through.
In a mixing bowl, combine the buffalo chicken with butter and half of the shredded cheddar cheese. Stir until everything is well mixed.
Once the potatoes are done baking, carefully remove them from the oven. Let them cool for a few minutes, then slice each potato down the center and gently scoop out some of the flesh, leaving enough to maintain the potato's structure.
Spoon the buffalo chicken mixture back into each potato, packing it in generously. Top with the remaining cheddar cheese.
Return the stuffed potatoes to the oven and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
Once baked, remove the potatoes from the oven. Drizzle with ranch or blue cheese dressing, sprinkle with crumbled blue cheese, and garnish with chopped green onions.
