Season both sides of the chicken thighs with the seasoning blend, to taste.
Season both sides with a bit of sea salt and freshly cracked pepper, to taste. If time permits, season the chicken and place it on a plate in the refrigerator uncovered for 2-3 hours before cooking. Remove the chicken from the fridge 30 minutes before cooking.
Preheat the oven to 400 degrees.
Heat 1 tablespoon of olive oil (or butter) in a cast-iron skillet over medium-high heat. Place directly into the HOT skillet skin side down, and cook for 4 minutes, or until the skin is golden brown and flips easily.
Flip the chicken over and place it into the preheated oven. Roast in the oven for 20-25 minutes, or until the chicken is golden brown and cooked through.
Remove the skillet from the oven and use tongs to remove the chicken from the skillet to a serving plate.
Serve the chicken thighs with fresh lemon on the side. Serve immediately. Enjoy.
