These roasted grilled potatoes rival any crisp, tender, golden brown roasted potatoes in the oven. Even better, you can rely on this technique when it’s sweltering outside and you crave roasted potatoes but want a respite from turning on the oven—and, by extension, heating up the entire kitchen.
It also means no running back and forth between stove and grill for the side dish next time you’re grilling. And it’s done without foil, which means no waste. (We thought you’d like all that.)

Notes on Ingredients
- Garlic–To crush garlic cloves, press on them with the flat side of a knife until they break. Don’t use minced garlic here as it will burn.
- Waxy potatoes–Choose red or yellow waxy potatoes, or use a mixture. Don’t use russet potatoes, as they don’t hold up as well as waxy potatoes.
How to Make This Recipe
- Preheat the grill to 500°F. Combine the oil and garlic in a flameproof roasting pan or large skillet.
- Heat the roasting pan or skillet on the grill until the oil begins to shimmer. Carefully add the potatoes and stir to coat the potatoes with oil.
- Cook the potatoes, stirring occasionally, until golden brown and tender. Season with salt, pepper, and rosemary, if desired.
- Transfer the grilled potatoes to a serving bowl or platter and serve hot.
Waxy potatoes are generally the first choice for potato dishes where you want your spuds to keep their shape—roasted, grilled, potato salads, or gratins. This category includes fingerlings, new potatoes, and red-skinned potatoes. But if you’re at the grocery store and you can’t remember a specific name, here’s a little trick—a waxy potato has a thinner skin that can be easily pierced or scratched with your fingernail.
To get crispy potatoes on the grill, make sure your oil is hot before adding the potatoes to it, and stir to coat them well. Also, don’t crowd the potatoes in your pan or skillet. If you have more potatoes than will fit in a single layer without being crowded, use a second pan or prepare them in batches.
- Be very careful when adding the potatoes to the hot oil, as it can splatter.
- Stir the potatoes regularly to help them crisp evenly.
- This recipe is suitable for gluten-free, dairy-free, and vegan diets.

Recipe Testers’ Reviews
Why have I not made roasted potatoes on the grill before? Wow, wow, wow! The very best roasted potatoes I’ve ever had. Seriously, these were amazing—nice and crisp with an amazing garlic and herb flavor. It all just worked amazingly well.
We served them with grilled red snapper and they were simply perfect. Oddly enough, there were some leftovers and we had them the next day, both cold and warmed up in the microwave, and though not as crisp as the day before, they still tasted just as good.
Oh my. These grill-roasted potatoes are delicious and an easy way to cook potatoes.
While the potatoes were roasting, I snipped some rosemary and added it to the pan, which I shook every now and then to sauté the potatoes, and voilà! I had roasted potatoes, easy peasy.
I grilled fish alongside them during the last few minutes and made a salad and everything was ready for alfresco dining. This will become a favorite. The only note of caution is to stir the pan or shake it to make sure the garlic doesn’t burn.
What a great recipe for roast potatoes on a grill. Easy, minimal ingredients, and super taste and texture.
I let my potatoes grill a few minutes longer to get a bit crisper. I used a combination of Yukon golds and red potatoes—I liked the red potatoes better. Be careful when adding the potatoes to the oil and do layer on the rosemary sprigs.
Use the leftover oil from these roasted potatoes on the grill to fry up any remaining potatoes for breakfast.
This recipe for roasted grilled potatoes is fabulous. If you’ve ever made roasted potatoes in the oven, you’ll really like this method. I followed the recipe exactly, and the potatoes turned out to be the most beautiful brown color. I wanted to eat them all myself!
My only caution is to watch the garlic and oil at the very beginning, as the garlic can turn black right before your eyes if you’re not careful. The only thing I’d change next time is to season the potatoes with salt, pepper, and rosemary at the beginning rather than the end. Other than that, this recipe is great! We’ll be making it, again and again, this summer.
A perfect addition to any summer meal that keeps the mess and heat out of the kitchen. My son did the grilling and the potatoes came out perfect—soft in the middle and crisp on the outside.
I put the potatoes in one of those large grill pans that has all the holes and hoped this would still work well. The only problem we had was with the oil causing the grill to flame up a bit, but that was fine.
I wondered if the garlic would be too much—3 cloves for 6 potatoes seemed like a lot—but it was very good. Next time, I may cut back a bit just for personal preference.
This technique for BBQ potatoes was a nice way to have crisp roasted potatoes in the summer without the heat of the oven.
I’d definitely play around with the seasonings and herbs, though I did enjoy the crisp bits of garlic. I didn’t have a flameproof roasting pan, so I used a wide stainless steel sauté pan instead and was able to fit all of the potatoes snugly in there.
