In a good-sized bowl, combine the ground turkey with the spices. This includes garlic powder, black pepper, sea salt, Dijon mustard, onion powder, paprika, and Worcestershire sauce. Fold in the parsley as well. Use a fork or your hands to mix thoroughly. Don’t overdo it, though; a gentle hand will keep the turkey from becoming tough.

Divide the turkey mixture into four equal portions. Roll each portion into a ball, then flatten it gently to form a patty about an inch thick. Creating a small indentation in the center of each patty helps prevent them from puffing up during cooking.

Set your air fryer to 360°F (182°C) and preheat it for about 5 minutes. This step is crucial for achieving a beautifully crispy texture.

Arrange the turkey patties in the air fryer basket. Make sure they do not touch each other to allow even cooking. Cook for about 12 minutes, flipping halfway through. The internal temperature should reach 165°F (74°C) when done.

Once cooked, let the turkey burgers rest for a couple of minutes. They’ll hold their juices better this way. Serve them on whole-grain buns, or enjoy them without for a low-carb option. Load them up with your favorite toppings, and you've got a meal that's good to go!
