Preheat the oven to 425°F and line a baking sheet with parchment paper.
Cook the fries according to package directions until crisp, then remove from the oven.
Reduce oven temperature to 400°F.
In a large bowl, beat together the softened cream cheese and sour cream until smooth.
Add 1 cup cheddar cheese, chopped jalapeños, ranch seasoning, and bacon. Mix until combined and set aside.
In a small pan, melt the butter over medium heat. Add the panko and cook for about 5 minutes, stirring often, until golden and toasted.
Spread the cream cheese mixture over the cooked fries in an even layer. Sprinkle with the remaining cheddar.
Top with toasted panko, plus extra bacon and jalapeño slices.
Bake for 10–12 minutes, or until the cheese is melted and everything is heated through.
Drizzle with ranch and garnish with sliced green onion before serving.
