Preheat the oven to 400°F (204°C) and position a rack in the middle.
Remove the neck and giblets from the chicken cavity, then season the inside generously with sea salt and black pepper.
Truss the chicken with kitchen twine to keep the legs and wings tucked and place it breast-side up in a 10" frying pan, cast-iron skillet, or on a parchment-lined baking sheet.
Season the outside of the chicken generously on all sides with sea salt and black pepper.
Roast on the middle rack at 400°F for about 60 minutes, or until the thigh reaches an internal temperature of 162°F (it will rise to 165°F with carry-over cooking).
Remove the chicken from the oven and transfer it to a plate or cutting board; let rest for 5 to 10 minutes before carving and serving.
