Remove chicken breasts from refrigerator 20-30 minutes before cooking to reach room temperature (approximately 65°F/18°C).
Pat chicken thoroughly dry with paper towels, applying firm pressure to extract maximum surface moisture.
Season both sides with salt, pepper, garlic powder, and paprika (if using). Allow seasoning to adhere for 5 minutes.
Heat a heavy-bottomed skillet over medium heat for 3-5 minutes until thoroughly heated.
Add oil and heat until it shimmers but doesn't smoke (approximately 350°F/175°C).
Place chicken breasts presentation-side down in the pan away from you. Immediately cover with splatter screen.
Cook undisturbed for 5-7 minutes until golden-brown crust develops and chicken releases easily from pan.
Flip using tongs, re-cover with splatter screen, and continue cooking for 5-6 minutes.
If using butter and aromatics, add them during the final 2-3 minutes of cooking. Tilt pan and baste chicken with the infused butter.
Verify internal temperature has reached 165°F (74°C) at the thickest part.
Transfer to a wire rack and rest uncovered for 5 minutes before serving.
