Preheat your oven to 425°F.

Place the chicken breast-side down on a cutting board. Using kitchen shears, cut along both sides of the backbone to remove it. Flip the chicken over and press down firmly on the breastbone to flatten the chicken.

Pat the chicken dry with paper towels. Rub the entire chicken with olive oil.

In a small bowl, mix together the salt, pepper, garlic powder, smoked paprika, and dried thyme. Sprinkle the seasoning mix evenly over both sides of the chicken.

Place the chicken breast-side up on a roasting pan or a baking sheet lined with foil.

Roast in the preheated oven for about 45 minutes, or until the internal temperature of the thickest part of the thigh reaches 165°F.

Remove the chicken from the oven and let it rest for 10 minutes before carving and serving.
