Preheat your oven to 425°F (220°C). Spread the frozen seasoned French fries evenly on a baking sheet and bake according to package instructions until golden and crispy, usually around 20-25 minutes.

While the fries are baking, combine the cooked shredded chicken with the BBQ sauce in a medium bowl. Stir until the chicken is well coated with the sauce. Season with garlic powder, salt, and pepper to taste.

Once the fries are done, remove them from the oven and carefully layer the BBQ chicken mixture over the fries.

Sprinkle the shredded cheddar and mozzarella cheeses evenly on top of the chicken.

Add the crumbled turkey bacon over the cheese, ensuring an even distribution for maximum flavor.

Return the loaded fries to the oven and bake for an additional 10-15 minutes, or until the cheese is fully melted and bubbly.

Remove from the oven and top with sliced green onions for a fresh finish. Allow it to cool for a few minutes before serving.
