First, gather all your ingredients for the chicken patties. In a large mixing bowl, add the ground chicken, eggs, breadcrumbs, minced garlic, minced onion, Dijon mustard, mayonnaise, fresh parsley, salt, and pepper. Use your hands or a spoon to gently mix everything together until just combined. Be careful not to overmix, as this can make the patties tough.
Next, line a baking sheet with parchment paper. Lightly grease your hands with a bit of oil to prevent the mixture from sticking. Scoop out even portions of the chicken mixture—about 4 ounces each—and gently shape them into patties that are about an inch thick. Place the formed patties on the prepared baking sheet.
Preheat a large skillet over medium heat and add a tablespoon of cooking oil. Once the oil is shimmering, carefully place the chicken patties in the pan, leaving some space between them. Cook for 6-8 minutes on each side, until they are golden brown and cooked through. The internal temperature should reach 165°F when checked with a meat thermometer.
While the burgers are cooking, prepare the sauce. In a small bowl, whisk together the mayonnaise, Dijon mustard, honey, and fresh lemon juice. Season with a pinch of salt and pepper to your liking. Once the patties are cooked, you can assemble your burgers with your favorite buns, a generous spread of the creamy sauce, and your chosen toppings.
