Pat the chicken breasts dry with paper towels to ensure a good sear, then season both sides generously with salt, pepper, and dried thyme.
Heat a heavy-bottomed skillet over medium-high heat, then add olive oil and let it shimmer, filling the kitchen with a fragrant aroma.
Place the chicken breasts in the hot skillet, laying them away from you to avoid splatters, and cook undisturbed for about 5-6 minutes until the edges turn golden and crispy.
Flip the chicken breasts using tongs and cook on the other side for another 5-6 minutes, until the meat is opaque and the internal temperature reaches 75°C (165°F).
Add minced garlic to the skillet and cook for about 30 seconds, until fragrant, taking care not to burn it.
Squeeze fresh lemon juice over the chicken and sprinkle lemon zest for a bright, tangy flavor, then cook for another minute to meld the flavors.
Remove the skillet from heat, let the chicken rest for 2-3 minutes to reabsorb juices, and then serve hot with your favorite sides.
