Fire up your Blackstone griddle to medium-low heat (around 350°F) and let it warm up completely.
02 -
Pour the vegetable oil onto the hot griddle and use your spatula to spread it evenly across the surface.
03 -
Carefully arrange the frozen sweet potato fries in a single layer. Add them gradually to prevent temperature shock that could damage your griddle.
04 -
Let the fries cook undisturbed for 2-3 minutes until they develop a golden-brown crust on the bottom. If you have a lid, you can close it to help them cook more evenly.
05 -
Flip the fries with your spatula and cook for another 2-3 minutes until they're crispy and golden all around.
06 -
Sprinkle the hot fries with salt and pepper while they're still on the griddle, then transfer to a serving plate and enjoy immediately!
