Mix the dry spice rub in a small mixing bowl. Divide the rub into two equal portions.
1 ½ teaspoon Granulated garlic, 1 ½ teaspoon Granulated onion, 1 ½ teaspoon Smoked paprika, 1 ½ teaspoon Dried thyme, 1 ½ teaspoon Brown sugar, 1 teaspoon Cayenne pepper, 1 teaspoon Kosher salt
Add the dried chicken thighs, Worcestershire sauce, and lemon juice to a medium bowl. Toss the chicken thighs so they are completely coated. Sprinkle in half of the dry rub, and toss again so that all the chicken thighs have a coating of blackening seasoning.
2 lbs Chicken thighs, 2 tablespoon Worcestershire sauce, 1 Lemon
In another small bowl, add the softened butter and remaining spice rub. Mix until the butter and spices are completely mixed together. Set aside at room temperature until you are ready to use.
½ cup Salted butter
Heat a large cast iron skillet over medium-high heat, with a thin layer of high smoke-point oil. Once the oil has started to shimmer, place the chicken thighs in the skillet with the skin side down. Turn the heat down to medium.
Let the skin sear in the skillet until it naturally lifts off from the skillet, and has become brown and crispy. This should take 5-7 minutes. Flip the chicken to finish cooking on the other side. The chicken should read 165°F on an instant-read thermometer.
Serve the chicken with a small spoon of the creole butter over top.
