In a large mixing bowl, combine the ground turkey, grated onion, minced garlic, beaten egg, breadcrumbs, Worcestershire sauce, smoked paprika, oregano, salt, and pepper. Mix gently with your hands until just combined – be careful not to overmix as this can make the burgers tough.

Divide the mixture into 4 equal portions. Gently shape each portion into a patty about ¾-inch thick. Use your thumb to make a slight indentation in the center of each patty – this helps them cook evenly and prevents them from puffing up.

Heat olive oil in a large skillet over medium heat. Cook the patties for 5-6 minutes per side, or until they reach an internal temperature of 165°F. For grilling, preheat grill to medium-high and cook for the same amount of time.

Transfer the cooked patties to a plate and let them rest for 3-4 minutes before serving. This allows the juices to redistribute throughout the meat, ensuring maximum flavor and tenderness.
