Preheat your oven to 200°C (390°F) and have your skillet ready on the stove.
Pat the chicken breasts dry with paper towels; this helps them crisp up nicely.
Season the chicken generously with salt, pepper, smoked paprika, and garlic powder, ensuring all sides are coated evenly.
Heat the skillet over medium-high heat until it’s hot and starts to shimmer, about 2 minutes.
Add a splash of olive oil to the skillet, then carefully place the chicken breasts in the pan, skin-side down if skin-on, or just side down if skinless.
Sear the chicken for 2-3 minutes on each side, until the edges are golden brown and fragrant, with a slight sizzle in the pan.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the internal temperature reaches 75°C (165°F).
Once cooked, remove the skillet from the oven and let the chicken rest for 5 minutes, loosely covered with foil to retain juices.
Squeeze fresh lemon over the chicken to brighten the flavors, then slice and serve.
