Begin by seasoning the chicken pieces evenly with kosher salt and freshly cracked black pepper, ensuring each piece is well-coated.
In a large skillet, heat olive oil over medium-high heat until it begins to shimmer. Add the chicken in batches, ensuring each piece has enough space to brown properly. Cook for 3-4 minutes on each side until the chicken is lightly browned and fully cooked through.
Lower the heat to a gentle simmer. Add the salted butter, buffalo sauce, garlic powder, and onion powder to the pan. Stir until each chicken piece is thoroughly coated with the rich, flavorful buffalo sauce.
Serve immediately with celery sticks for crunch and blue cheese dressing on the side for dipping.
