Prepare the Burger Mixture: In a large bowl, combine the ground chicken, panko breadcrumbs, parsley, Worcestershire sauce, Dijon mustard, garlic powder, onion powder, salt, and pepper. Crack the egg into the bowl and scramble it with a fork to break up the yolk. Then, gently combine all the ingredients with the fork or your hands. Be careful not to overwork the mixture to keep the burgers tender.

Shape the Patties: Shape the chicken mixture into 4 patties, each about 1/2-inch thick and 4½ inches across. The mixture will be soft and wet, so work gently. If you find it easier, return the patties to the bowl before gently lifting them with your hands and transferring them directly into the hot skillet.

Cook the Burgers: Heat the oil in a large cast-iron skillet, nonstick skillet, or grill pan over medium-high heat. Let it heat for a few minutes until it’s shimmering and ready. Add the patties to the skillet and cook for about 4 minutes on the first side, or until golden brown. Flip the burgers and cook for another 4 minutes, or until the internal temperature reaches 165°F (74°C). If adding cheese, place it on top of the patties right after flipping and cook until melted.

Toast the Buns (Optional): While the burgers are cooking, if you’d like to toast the buns, preheat the oven to 400°F. Place the buns cut-side up on a baking sheet and toast for about 5 minutes, or until lightly browned.

Assemble the Burgers: Place each cooked chicken patty on the bottom half of a toasted bun. Add your desired toppings (lettuce, tomato, onion, pickles, cheese, and condiments). Top with the other half of the bun. Serve immediately and enjoy!

These juicy chicken burgers are flavorful and simple to prepare, with a great texture thanks to the panko breadcrumbs. Perfect for a delicious homemade burger!
