Preheat the broiler. Adjust the oven rack to the middle of the oven so that the chicken will be 4-5 inches from the heating element. Line a 9-inch x 13-inch broiling pan with foil and set aside. You can also use a cast iron skillet. Make sure that whichever pan you use is rated for use with the broiler.
Melt butter with the garlic in the microwave, then mix in Worcestershire sauce and black pepper.
Pat chicken dry. Remove the skins if desired, or leave on for a crispy exterior. Arrange in the broiling pan, skin side up. Brush with the butter mixture, reserving some for basting. *Note - wash your brush inbetween basting to avoid contamination.
Broil for about 20 minutes in the preheated oven, until juices run clear, turning occasionally and basting with remaining butter mixture (use a clean brush each time to avoid contamination). Finish with skins up so they can get crispy. Internal temperature should be 165-170 F.
Let chicken rest for 5-10 minutes, tented loosely with foil, then garnish with fresh minced parsley and serve.
Notes
Broiled chicken thighs make excellent leftovers. Remove chicken from the bone and use in soups, salads or sandwiches, or for your weekly lunch prep. Store leftovers in an airtight container in the fridge for up to 4-5 days or freeze in a plastic freezer bag for up to 3 months. Thaw before reheating.
