In a small bowl, combine paprika, garlic powder, onion powder, thyme, salt, black pepper, and cayenne pepper to create the blackening spice mix.

Pat the chicken breasts dry with paper towels to ensure the spices stick well.

Rub each chicken breast evenly with the spice mixture, pressing the spices into the meat to coat thoroughly.

Heat olive oil in a large skillet over medium-high heat until hot but not smoking.

Place the chicken breasts in the skillet and cook for about 6-7 minutes on each side, or until the outside is charred and the inside is cooked through, reaching an internal temperature of 165°F.

Remove the chicken from the skillet and let it rest for a few minutes before slicing. This helps retain the juices and flavors.
