In a chilled mixing bowl, combine kosher salt, cracked black pepper, garlic powder, onion powder, and Worcestershire sauce with ground turkey. Mix gently until just combined.

Divide the mixture into four equal portions, about 6 ounces each, and shape them into 1-inch thick patties. Create a small dimple in the center of each patty.

Preheat your grill to medium-high heat, around 375°F to 450°F, and lightly oil the grates with a paper towel dipped in olive oil.

Place the patties on the grill at a 45-degree angle and sear for 4 to 5 minutes.

Flip the patties and cook for an additional 4 to 5 minutes, checking the internal temperature to reach 160°F (71°C).

Remove the burgers from the grill and let them rest for 5 minutes. Garnish with fresh parsley before serving.
