Season both sides of the chicken thighs with fresh thyme leaves, sea salt, and freshly cracked pepper to taste.
Heat the oil in an OVENSAFE large skillet over high heat.
Once the oil is shimmering, add the seasoned chicken thighs skin-side down. Cover with a splatter screen, and sear the skin for 8-10 minutes. Be patient. Don’t try flipping early. It’ll release easily from the pan once it’s ready to flip, but you want to make sure the skin is rendered, crispy, and beautifully golden brown.
Flip the chicken over and add a few sprigs of thyme to the skillet.
Place it in the preheated oven and cook for 20-25 minutes, or until the chicken is cooked through, according to a meat thermometer.
