Preheat and prep the potatoes. Heat your oven to 400°F (200°C).
Pierce each sweet potato a few times with a fork. Rub lightly with olive oil and sprinkle with a little salt.
Bake until tender. Place potatoes on a baking sheet and bake for 45–60 minutes, depending on size, until a knife slides in easily. If you’re short on time, microwave the potatoes first for 6–8 minutes, then finish in the oven for 20–25 minutes for better texture.
Mix the buffalo chicken. In a bowl, combine shredded chicken, buffalo sauce, melted butter, garlic powder, and onion powder.
Taste and season with salt and pepper. Add more buffalo sauce if you like it spicier.
Split and fluff. When the potatoes are done, let them cool slightly. Slice each lengthwise, then gently push the ends toward the center to open.
Fluff the flesh with a fork to make room for the filling.
Stuff generously. Spoon the buffalo chicken into each potato. Scatter chopped celery over the top if using.
Add cheese and melt. Top with shredded cheese (or blue cheese crumbles). Return to the oven for 5–8 minutes, or switch to broil for 2–3 minutes, until the cheese is melted and bubbly.
Keep an eye on it.
Finish with cool toppings. Drizzle with ranch or blue cheese dressing. Sprinkle with green onions and herbs. Add extra buffalo sauce if you want more heat.
Serve hot. Plate with a crisp side salad or extra celery sticks for crunch.
