Gather all ingredients including ground chicken, fresh spinach, sharp white cheddar cheese, garlic powder, panko bread crumbs, egg, salt, pepper, and olive oil.

In a large bowl, combine ground chicken, chopped spinach, grated white cheddar, garlic powder, salt, pepper, panko, and egg. Mix gently until just combined.

Shape the mixture into patties approximately 1 inch thick and set them aside on a plate.

Heat olive oil in a skillet over medium heat. Cook patties for 5-6 minutes on one side until golden brown, then flip and cook on the other side for another 5-6 minutes.

Transfer the cooked patties to toasted buns and serve with your favorite toppings.
