Trim any excess fat from the chicken and cut it into small pieces about 1/3" thick. Place the chicken pieces in a large mixing bowl.
Add 1 cup plain breadcrumbs, 1/2 cup Ranch dressing, 2 eggs, 2 tbsp chopped dill, 1/2 tsp salt, and 1/4 tsp pepper to the bowl. Mix until the ingredients are evenly combined.
Use a 1/3-cup measure to portion the mixture and press each portion into a compact patty. Place formed patties on a plate or tray.
Heat a large non-stick skillet over medium heat and add 2 tbsp oil, tilting the pan to coat the surface; heat until the oil is shimmering.
Fry the patties in a single layer (do not overcrowd the pan), uncovered, about 3–4 minutes per side, flipping once, until each side is golden brown and the patties are cooked through.
Confirm doneness by internal temperature (165°F) or by cutting one open to ensure there is no pink in the center and juices run clear.
Transfer cooked fritters to a paper-towel-lined plate to drain briefly before serving.
