In a medium bowl, add ground chicken, breadcrumbs, mayonnaise, onions, parsley, garlic, paprika, salt and pepper. Use your hands to combine all the ingredients together until blended, but don’t over mix.
Preheat grill to medium-high heat and oil the grates.
Form the mixture into 4-6 equal patties. Press down in the middle of each patty with your thumb to ensure even cooking of the chicken burgers.
Cook the chicken burgers on the preheated grill until the internal temperature is 165F, about 10 minutes total, flipping halfway through.
Assemble the chicken burgers with hamburger buns and toppings of choice.
