Prep: Preheat your oven to 350°F (175°C).
The Mix: In a large mixing bowl, combine the ground chicken, shredded cheddar, ranch dressing, garlic powder, and onion powder. Mix gently until the ingredients are just incorporated—over-mixing can lead to a tougher patty.
Form Patties: Divide the mixture into 12 small patties, shaping them to fit the size of your slider buns.
Bake: Arrange the patties on a baking sheet. Bake for 20 minutes, or until the internal temperature reaches 165°F (74°C) and the cheese is visible and bubbly.
Toast (Optional): While the chicken is baking, slice your slider buns. You can lightly toast them in the oven during the last 3 minutes of baking for extra crunch.
Assemble: Place one hot chicken patty on each bun. Top with a generous sprinkle of fresh green onions.
Serve: Enjoy these warm, perhaps with a side of sweet potato fries or a crisp slaw.
