In a medium bowl, mix the tzatziki sauce ingredients. Cover and refrigerate for an hour to let the flavors blend.

For the burger patties, combine ground turkey, Italian seasoning, garlic, onion, parsley, smoked paprika, pepper, and salt in a large bowl bowl. Use your hands to thoroughly blend. Shape the mixture into 6 burger patties, slightly larger than the hamburger buns.

Place the patties in the air fryer basket, spray with cooking oil spray, and cook at 360 degrees for 7 minutes. Flip the patties and cook for an additional 5 minutes or until they are fully cooked.

To assemble the burgers, start with a layer of tzatziki sauce, followed by the patty, tomato, lettuce, more tzatziki sauce, and crumbled feta. Enjoy! These turkey burgers can be cooked on the stovetop in a cast iron skillet or grilled on a barbecue, or even using a George Foreman grill . You can also bake them in the oven by placing them on a rimmed baking sheet at 425°F for 15 minutes. Regardless of your cooking method – gas, campfire coals, oven, or stovetop – ensure that the turkey burgers reach an internal temperature of 165°F for safe consumption. The easiest way to check doneness is to use a cooking or meat thermometer, inserting it into the thickest part of the patty, and only remove the turkey burgers from heat when they reach that internal temperature of 165°F.
