In a large mixing bowl, combine the ground chicken, crushed Oreo cookies, shredded cheddar cheese, ranch dressing, panko breadcrumbs, chopped green onions, garlic powder, onion powder, salt, and pepper. Mix gently for about 2-3 minutes until just combined.

Divide the mixture into four equal portions and shape each into a 1-inch thick patty, ensuring uniform sizing.

Heat a grill or skillet over medium heat to about 350°F (175°C). Cook patties for 5-6 minutes per side until golden brown and cooked through.

Lightly toast the hamburger buns on the grill or in a skillet over low heat for about 1-2 minutes until golden.

Assemble the sliders by placing each patty on the bottom half of a bun, adding your favorite toppings.

Serve immediately while warm, paired with fries or salad for a complete meal.
