Bake the fries according to package instructions.
16 ounces frozen shoestring fries
While the fries are baking, melt the butter and garlic in a medium saucepan set over low heat.
2 tablespoons unsalted butter, 1 clove garlic
Once the butter begins to gently simmer, cook the garlic until slightly toasted, about 90 seconds. Add in the garlic salt, pepper, cayenne, and 2 tablespoons of the Parmesan cheese. Heat just until the cheese is melted. Stir well to combine.
¼ teaspoon garlic salt, ⅛ teaspoon freshly ground black pepper, 1 pinch ground cayenne pepper, ¼ cup freshly grated Parmesan cheese
Once the fries are crispy, remove from the oven and pour the butter mixture over the fries, tossing well to coat.
Transfer the fries to a serving platter and sprinkle them with the remaining Parmesan cheese and parsley. Serve immediately.
2 tablespoons fresh minced parsley
