Carefully butterfly each chicken breast, creating two thin cutlets from each breast. If you purchased cutlets, skip this step.
2 boneless, skinless chicken breasts
In a small bowl, mix together smoked paprika, garlic powder, salt, onion powder, dried thyme, cayenne pepper, black pepper, and dried oregano to create the blackening spice mix.
2 teaspoons smoked paprika, 1 teaspoon garlic powder, ¾ teaspoon kosher salt, ½ teaspoon onion powder, ½ teaspoon dried thyme, ½ teaspoon cayenne pepper, or to taste, ½ teaspoon coarse ground black pepper, ¼ teaspoon dried oregano
Heat a heavy skillet or cast-iron pan over medium-high heat until it's very hot.
Pat the chicken breasts dry with paper towels. Rub each chicken breast with the spice mix, until it’s well coated on both sides.
Add oil to the hot pan. Carefully place the seasoned chicken breasts in the pan. Cook for about 5 minutes per side or until the internal temperature reaches 165°F (74°C) and the exterior is blackened and crusty.
2 tablespoons olive oil
Remove the chicken from the pan, place on a plate, and let it rest for 3 to 5 minutes.
Slice the blackened chicken or serve the cutlets whole. Squeeze fresh lemon juice over the top if desired.
Fresh lemon wedges for serving
Notes
If you’d rather not cut the chicken yourself, you could buy thin cutlets instead of whole breasts.
Adjust the level of cayenne pepper according to your spice preference. If you like it spicier, feel free to add more.
