Pat the chicken thighs dry thoroughly with paper towels to remove excess moisture, which helps the skin crisp up nicely. Season generously all over with salt and pepper.
Place a heavy-bottomed skillet on medium heat and add a tablespoon of olive oil or duck fat. Let the oil warm up gently—this prevents sticking and encourages even searing.
Lay the chicken thighs skin-side down into the cold skillet, pressing gently to ensure full contact with the pan. Cook for about 8-10 minutes, watching the skin turn a deep, golden, crackly hue as it crisps up.
Carefully flip the chicken thighs using tongs, then cook for another 8-10 minutes until the internal temperature reaches 74°C (165°F). The meat should be juicy and tender, with the skin remaining crispy.
During the last minute of cooking, add the smashed garlic cloves and herbs to the pan. Let their aroma fill the air as the garlic develops a fragrant, smoky scent.
Remove the chicken from the skillet and let it rest on a plate for about 5 minutes. Resting allows the juices to redistribute, keeping the meat moist and flavorful.
Squeeze fresh lemon juice or splash vinegar over the rested chicken to brighten the flavors and cut through the richness of the crispy skin and tender meat.
Serve the chicken thighs hot, with the crackly skin and tender meat on full display—perfect for a quick, satisfying dinner.
