Start by preheating your Blackstone griddle to medium heat. You want the surface hot enough to crisp the fries without burning them too quickly.

Add a small amount of oil to the griddle and spread it around evenly using a spatula.

Pour the frozen fries directly onto the hot Blackstone in a single layer. Avoid overcrowding the fries because this can cause steaming instead of crisping.

Cook the fries for about 12 to 18 minutes depending on the thickness of the fries. Thin fries will cook faster while steak fries or waffle fries may need extra time.

Use a spatula to flip and move the fries every few minutes so they cook evenly on all sides. As the fries cook, they will become golden brown and crispy.

Once the fries are fully cooked, sprinkle with salt and your favorite seasonings while still hot.

Serve immediately for the best texture and flavor.
