Preheat the oven to 450°F (232°C). Line a baking sheet with foil and place a wire rack on the sheet; spray the rack lightly with nonstick spray.
Trim the chicken and cut it into fry-sized strips, then set aside.
Place the potato chips in a blender or food processor and pulse until they are fine crumbs.
Transfer the crushed chips to a large shallow bowl and stir in the panko breadcrumbs until evenly combined.
In a medium saucepan over medium heat, melt the butter and stir in the onion salt, garlic salt, and kosher salt until combined.
Dip each chicken strip into the melted butter to coat, then dredge in the chip-and-panko mixture, pressing gently so the coating adheres.
Place the coated chicken fries on the prepared wire rack spaced evenly, season with additional salt and pepper to taste if desired.
Bake in the preheated oven for 18–20 minutes, until the chicken is cooked through and the coating is golden and crisp.
Remove from the oven and let the chicken fries rest on the rack for a few minutes before serving with your preferred dipping sauce.
