Prepare the chicken mixture by placing ground chicken in a large mixing bowl and letting it sit for 15–20 minutes.

Add the shredded cheddar cheese, ranch seasoning, breadcrumbs, and finely chopped green onions to the chicken mixture. Season with salt and pepper. Mix gently until just combined.

Form the mixture into four patties, about ½ to ¾ inch thick, making a thumb indentation in the center.

Wrap the patties in plastic wrap and chill them for at least 15 minutes.

Preheat the grill to medium-high heat (375°F to 400°F).

Cook the patties on the grill for 5–6 minutes per side until they reach an internal temperature of 165°F.

While cooking, toast the burger buns until golden brown.

Assemble each burger with a patty on a toasted bun and your choice of toppings.
