In a large mixing bowl, combine ground chicken, chopped spinach, shredded cheddar cheese, breadcrumbs, minced garlic, onion powder, salt, and black pepper. Mix until fully blended.

Divide the mixture into four portions, shaping each into a patty about ½ inch thick.

Heat olive oil in a skillet over medium heat until shimmering, then add the patties.

Cook patties for about 5–7 minutes on each side until golden brown, ensuring internal temperature reaches 165°F (74°C).

Toast burger buns in the oven or on a griddle until warm and slightly golden.

Place each patty on a toasted bun and top with preferred toppings.

Serve immediately with favorite condiments and enjoy with family or friends!
