French fries and the grill are not something most people do. But with the right technique, this can be a standard with these easy to follow step by step photo instructions.

Introduction
There are only a few instructions out there, and they vary a lot. So I always like to experiment, and this is the 5th try in 2 weeks, and I now have it right.
They are not your basic fast food tasting fry. They are a cross between a fast-food fry and a hash brown. And a great reason to buy that 10 or 12-inch cast iron pan.
My Rating
This will continue to be a frequent side when not in diet mode.
♨️The Grill
The grill should be 450°-500° surface temperature. That is usually a bit above medium on most gas grills. It is also the grill temperature I usually recommend for most chicken and pork recipes.
If you have questions about grill set up, see A Beginners Guide to Grill Temperature on a Gas Grill.
Try to avoid any "hot spots" you have on your grill. A heavier pan like cast-iron will help even out any hot spots. The larger the pan, the better.
🥔Potatoes
Russet or Yukon Gold potatoes are a good choice here, but most potatoes should work. You can leave the skin, but I suggest peeling if using Russets. Other potatoes have thinner skin, and peeling is more a personal choice.
I suggest ¼ inch fries. The thicker the fries, the longer and harder the cooking. I use a mandolin, but please follow the safety recommendations of the manufacturer if you do. Otherwise, just a good knife will do.
The potatoes need to be soaked for 10-20 minutes in cold water and then dried well before proceeding. If you skip this still, you will have a mushy mess.
✔️Tips
- Try to avoid any hot spots on your grill.
- Do thin fries-They need to cook completely on the grill. Thicker than ⅜ inch will not do.
- They go on raw, not precooked. I tried to a varying amount of precooking, and they became too weak to work.
- Wash and soak them after cutting. The starch will stick them together. Then pat dry (important.)
- Rotate the pan every time you touch the fries. Hot spots will do you in.
- Keep your hands off a lot more than you want. You will just break them up.
- A well-seasoned cast-iron pan is almost a must.
It is another KISS recipe that is easily scalable to the size you need, but you will have a hard time doing a large batch. More than 2-3 pounds of potatoes should be a practical limit in a very large pan.

Cooking about 30-35 minutes total until well browned. Remove from grill. Place on a paper towel-lined bowl and sprinkle with coarse salt.

Leave the grill open or closed?
Dan Mikesell AKA DrDan
Closed. General rule. Under 1/2 inch thick can be open or closed. 1/2 to 1 inch preferred closed. Over 1 inch is always closed. When in doubt- closed.

Thanks! Easy and delicious.

How can you call this recipe grilled french fries if the potatoes never touch the grill?
Evan
Julian, Julian, Julian. What are you doing with your life, man? It’s just a recipe; you don’t have to criticize. If you don’t like then it just keep looking until you find the right one. It’s a big world out there.

Hi Evan,
Welcome to the blog and thanks for the defense.
I probably should have just deleted the comment but I had the image of him laying his fries across the grill grate and then trying to flip them. So I just let it pass. I find odd things funny.

I only have olive oil can I still make it work if I’m careful?
DrDan
I don't think it will work well. It needs to get very hot.
Bob Willoughby
What a great post. I just got a Camp Chef flat top griddle. This looks like a great way to do fries. Have you ever tried peanut oil? Do you know the temperature of the cast iron pan?
Thanks!
DrDan
Hi Bob,
Peanut oil, of course, would be fine. The grill surface temperature on that grill was probably about 450-500 degrees. The pan temp unknown. But darn hot at the end.

Thanks for offering the recipe again with some great pictures. I will candidly admit that a picture of the dish surely adds to my interest in making it. And this recipe definitely has a fresh and tempting flavor to it that I loved.

I just did this about a week ago and loved them. We did ours indirect at 425f (ish). A cast iron like yours would have been better, we used a 1/4 jelly roll pan.
