Place your whole chicken breast-side down on a cutting board. Cut along one side of the backbone with kitchen shears, then remove it completely. Repeat on the other side.

Locate the breast bone and make a small cut on each side. Press down on the chicken's breast until you hear a crack, indicating it's flattened.

Preheat your oven to 400°F (200°C). In a bowl, combine olive oil, smoked paprika, garlic powder, kosher salt, and black pepper. Rub the mixture evenly over the chicken.

Transfer the seasoned chicken onto a rimmed baking sheet, skin-side up. Roast for about 1 hour or until the skin is golden and crispy, checking the internal temperature.

Remove the chicken from the oven and cover loosely with foil. Let it rest for 10-15 minutes to allow juices to redistribute.
