Gather all your ingredients and tools—lean ground chicken, fresh spinach, sharp white cheddar, panko bread crumbs, an egg, garlic powder, salt, pepper, and olive oil.

In a large mixing bowl, combine the ground chicken, chopped fresh spinach, shredded white cheddar cheese, and garlic powder. Season with salt and pepper, then sprinkle in the panko bread crumbs. Crack the egg into the bowl to bind the mixture together.

Take a handful of the mixture and shape it into a patty about 1 inch thick.

Heat olive oil in a large skillet over medium heat until shimmering.

Add the shaped patties to the skillet and cook for 5-6 minutes on one side without moving them until golden brown.

Flip the patties and continue cooking for another 5-6 minutes until they reach an internal temperature of 165°F (75°C).

Remove the cooked burgers from the skillet and let them rest for a couple of minutes. Serve on toasted buns with your choice of toppings.
