In a mixing bowl, combine the ground chicken, shredded cheddar cheese, ranch seasoning, salt, and pepper. Use your hands to mix until just combined—be careful not to overmix as that can result in tough burgers.
Divide the mixture into four equal portions and shape them into round patties about ¾ inch thick. Use your thumb to make a small indent in the center of each patty. This prevents the burgers from puffing up while cooking.
Heat a grill or griddle over medium heat and lightly oil the surface to prevent sticking. Ensure it’s hot enough by sprinkling water on it; if it sizzles, it’s ready!
Add the patties to the grill and cook for about 5-7 minutes on each side or until the internal temperature reaches 165°F. If you’re adding cheese on top, place a slice on each patty during the last minute of cooking to melt.
Toast your burger buns on the grill if desired. Place a patty on each bun and add your choice of toppings like lettuce, tomatoes, or avocado.
Serve immediately with your favorite sides, such as sweet potato fries or a fresh salad.
