Ingredient Talk

I’ve tested thicker fries, and they just don’t crisp up the same—medium to thin frozen fries (like shoestring or regular cut) work best on the griddle.

Avocado oil is my go-to for getting that golden crunch, but canola, olive, or vegetable oil all work fine too.

Tips and Tricks

Don't Skip Thawing: Dumping a frozen hunk of French fries on your grill top can actually damage it. Make sure you take your fries out of the freezer and let them thaw for a few minutes.
Post-Cooking Crispiness: To keep fries crispy after cooking, consider placing them on a cooling rack with a tray underneath. This prevents steaming, keeping your fries crispier for longer.
Reheating: If you have leftovers, reheat them on the griddle over medium-high heat instead of the microwave. An air fryer is also a good alternative.
Cooking Times Vary: Depending on the fries you are cooking, you may need to adjust the cooking time. Thicker fries will take longer to cook than shoestring fries.

Step by Step

For the full recipe with measurements, see the recipe card at the bottom of the post.

Frozen fries that have been added to oil on a Blackstone griddle. — Remove your fries from the freezer and place them into a bowl while you preheat your griddle to medium-low heat. If your griddle comes with a cover, keep it closed during preheating. Evenly spread the oil over the section of the griddle where you will cook the fries. Place the slightly thawed fries in a single layer on the griddle, making sure to break apart any large clumps beforehand.

French fries on a paper towel lined baking sheet. — Remove from the griddle, and place on a baking sheet lined with paper towels. Season with salt (and pepper if you like) and serve while warm.
