What Are Grilled Sliced Potatoes?

Outside the United States, the practice of grilling sliced or flat-cut potatoes can be traced back to various European cuisines, particularly in Mediterranean countries like Italy and Greece, where simple vegetables were grilled with olive oil, herbs, and salt. In these cultures, grilling was not just a cooking method but a communal experience—bringing people together around fire pits or stone ovens. The dish often accompanied meats or was served as a rustic antipasto, showcasing regional olive oils and aromatic herbs like rosemary or thyme.

In the United States, grilled sliced potatoes evolved alongside the rise of backyard barbecuing in the mid-20th century. As American grilling culture boomed, especially in suburban settings, home cooks began experimenting with grilling not only meats but vegetables and starches like potatoes. Thinly sliced or halved potatoes brushed with butter, garlic, and spices became a staple side dish, embodying the American values of simplicity, versatility, and bold flavors. Today, they remain a crowd-pleaser at cookouts and family gatherings, celebrated for their crisp edges, soft centers, and ability to pair perfectly with grilled meats or stand on their own.

Pro Tips for The Best Grilled Sliced Potatoes

• Aim for slices about 4–5 mm thick to ensure even cooking and a perfect crisp-tender balance.
• A properly heated grill or grill pan ensures crisp edges and defined grill marks.
• Space the slices apart on the grill for consistent heat exposure and better texture.
• Sprinkle fresh rosemary or thyme after cooking to preserve their flavor and prevent burning.

How Long Do Sliced Potatoes Take on The Grill?

Sliced potatoes typically take about 10 to 15 minutes on the grill, depending on their thickness and the heat level. Flip them halfway through to ensure even browning and a crisp exterior.

What Are The Best Potatoes to Grill?

The secret to getting a good result is to cook the potatoes with the skin, which gives an additional crunchy note and makes them better resistant to high temperatures. So choose yellow-fleshed potatoes, fresh and with thin skin, preferring organic and untreated ones, and put them on the grill still wet with water, so that they become super fragrant.

Are You Supposed to Boil Potatoes Before Grilling?

The peculiarity of this preparation is that the potatoes are not boiled before cooking: just cut them into thin slices and leave them in water for half an hour to become crispy on the outside and soft on the inside.

Can I Cut Them In a Different Way?

Yes, you can cut the potatoes in different ways—such as wedges, rounds, or lengthwise planks—but keep in mind that thicker cuts will need longer cooking times and may benefit more from pre-boiling to ensure they cook through evenly on the grill.

What Else Can I Flavor Them With?

Try adding smoked paprika, garlic powder, chili flakes, lemon zest, or grated Parmesan cheese for extra depth. Marinades made with balsamic vinegar, mustard, or infused oils can also enhance their taste. Fresh herbs like parsley, chives, or dill added after grilling bring a bright, aromatic finish.

What Can I Serve Them With?

Serve them alongside grilled meats like steak, chicken, or sausages, or with fish for a lighter option. They also complement vegetarian mains such as grilled vegetables, halloumi, or a hearty salad. For a casual meal, they’re great with burgers or sandwiches, and can even be topped with sour cream or a yogurt dip for a tasty appetizer.

Can I Make Grilled Sliced Potatoes Ahead of Time?

Yes, you can make grilled sliced potatoes ahead of time. Slice them in advance, then store them in the fridge for up to a day. When you're ready to serve, simply brush with oil and reheat them on the grill or in a hot oven to restore their crispiness and flavor.

Do They Freeze Well?

Grilled sliced potatoes do not freeze very well, as freezing can alter their texture, making them mushy or grainy once thawed.

How to Store Any Leftovers

To store leftover grilled sliced potatoes, let them cool completely, then place them in an airtight container and refrigerate. They’ll stay fresh for up to 3 days. Reheat them in a skillet, oven, or air fryer to restore their crisp texture—avoid microwaving if you want to maintain the crispness.

How to Make Grilled Sliced Potatoes

First, wash the potatoes well under running water, then dry them and cut them into thin slices of about 1 centimeter, without removing the peel.

Place them in a large bowl filled with water and let them rest for at least half an hour, so that they lose the excess starch.

Now heat the grill or griddle and arrange the potatoes, without overlapping them; the ideal cooking temperature would be 320°F/160°C, but in general the grill must be hot and not boiling, to avoid burning them. Turn them every 5 minutes, so as to cook them evenly, and remove them from the heat when they are golden brown on both sides.

At this point, transfer them into a container or onto a serving dish and season them with extra virgin olive oil, salt, pepper and rosemary.

Enjoy them while they're piping hot!
