Preheat oven to 450 degrees Fahrenheit.
In a large mixing bowl, mix together the Sriracha sauce, olive oil, salt, and pepper.
Add the potato strings or wedges to the bowl and stir to thoroughly coat them.
On a foil-lined baking tray, evenly spread the coated fries.
Bake the fries for 25 to 30 minutes, or until golden brown, flipping the fries once during the process.
Remove from oven, and serve while hot.
