Let's be honest: in the great theater of backyard barbecue, potatoes are usually the forgotten understudy. They get wrapped in a foil straitjacket and banished to the edge of the grates until they turn into sad, starchy mush. No more. To grill potatoes perfectly on a flat top, parboil them until fork-tender, slice or smash them, and sear them on an oiled 400°F griddle for 10 to 15 minutes until a golden, crispy crust forms. Cooking them directly on a flat steel surface gives you maximum contact area, transforming a boring spud into a savory, crispy masterpiece that will have your guests fighting over the last bite. Let's get that fire going and give the humble potato the respect it deserves.
The Quick Take
To achieve a perfectly crispy exterior and a fluffy interior, parboil your potatoes in salted water for 8 to 10 minutes first. Once drained and slightly cooled, slice them half an inch thick or smash them flat. Sear them on a well-oiled flat top cooktop between 375°F and 400°F for 5 to 7 minutes per side. Press them down lightly to ensure maximum surface contact, and do not flip them until a deep golden-brown crust releases naturally from the steel.

Setting Up for Success
Grilling vegetables over an open flame usually involves a delicate balancing act to keep your food from falling through the grates as a sacrifice to the fire gods. That is exactly why cooking on a flat top is an absolute game-changer for potatoes. The solid steel surface catches every drop of oil, every grain of seasoning, and creates an uninterrupted canvas for building a serious crust.On an Arteflame grill, the flat solid-steel cooktop surrounds an open center fire, naturally creating distinct heat zones. The steel is over 400°F near the blazing center and gradually cools toward the outer edge. This means you don't have to fiddle with dials to manage your temperatures. You can aggressively sear your potatoes near the middle, then simply slide them out to the cooler perimeter to keep them warm while you finish grilling your steaks on the center grate.
Step-by-Step Instructions
-
Prep the grill: If you are using an Arteflame, pour a little vegetable oil on three paper napkins, place them in the center of the grill, stack your firewood over the napkins, and light the paper. You will be ready to cook in about 20 minutes.
-
Parboil the potatoes: Boil whole baby potatoes or potato chunks in heavily salted water for 8 to 10 minutes until just fork-tender. Drain them and let them steam dry for 5 minutes. Moisture is the enemy of a crispy crust.
-
Smash or slice: For baby potatoes, place them on a cutting board and press down gently with the bottom of a heavy glass to smash them to a 1/2-inch thickness. For larger potatoes, slice them into 1/2-inch thick rounds.
-
Oil the flat top: Lay down a generous squeeze of high-smoke-point oil (like avocado or canola) on the hot steel cooktop. Spread it evenly.
-
Sear and crisp: Place the potatoes onto the oiled surface. Let them sizzle undisturbed for 5 to 7 minutes. When the edges turn golden brown and they release easily from the steel, flip them and cook the other side for another 5 minutes.
-
Season and serve: Move the potatoes to a cooler zone. Toss them with a small pad of butter, salt, pepper, and fresh herbs right on the steel, then remove and serve.
Pro Tip: For a steakhouse-quality flavor upgrade, swap out your standard cooking oil for beef tallow or duck fat when searing the potatoes. The animal fats handle the high heat beautifully and deliver an incredibly rich crust.
Common Mistakes to Avoid
-
Skipping the parboil: Trying to cook raw potatoes entirely on the flat top results in a burnt exterior and a raw, crunchy center. Always boil them first.
-
Flipping too early: If you try to flip the potato and it sticks, it isn't ready. A proper crust will naturally release from the steel. Use a sturdy OXO griddle spatula with a beveled edge to get cleanly under the crust.
-
Fear of oil: Potatoes act like little sponges. If your flat top is dry, the potatoes will burn instead of frying. Keep a thin, visible layer of oil under them at all times.
-
Using the wrong salt too early: Table salt can taste harsh. Finish your potatoes right at the end of the cook with a generous pinch of Diamond Crystal Kosher Salt for the perfect clean, salty crunch.
Make It Your Own
-
Loaded Smashed Potatoes: In the last two minutes of cooking, top each smashed potato with shredded cheddar and bacon bits. Let the cheese melt directly on the warm edge of the cooktop.
-
Spicy Cajun Hash: Dice your parboiled potatoes instead of slicing them. Toss them on the flat top with diced onions, bell peppers, and a heavy dusting of Cajun seasoning.
-
Garlic Parmesan Finish: Right before pulling the potatoes off the heat, toss them with minced garlic, fresh parsley, and freshly grated parmesan cheese.
-
Breakfast Potatoes: Cook them in the residual bacon grease left on your flat top from the morning's breakfast run.
Frequently Asked Questions
Do I really have to parboil potatoes before grilling?
Yes, parboiling is essential for the best texture. Boiling the potatoes first ensures the inside is fluffy and fully cooked, allowing you to use the high heat of the flat top purely to build a crispy, golden crust without burning the outside.
What are the best potatoes for a flat top?
Yukon Gold and red baby potatoes are the best choices for flat top grilling. Their waxy texture holds together perfectly when smashed or sliced, whereas russet potatoes can sometimes crumble and fall apart during the flipping process.
Should I peel the potatoes first?
Leave the skin on! The potato skin crisps up beautifully on the hot steel and adds fantastic rustic flavor and texture to the final dish. Just be sure to scrub them clean before parboiling.
Keep the Fire Going
You now have the power to make a potato side dish so good, it might just upstage the main course. The beauty of cooking on a flat steel cooktop is that cleanup is just as easy as the cook—simply scrape the leftover oil and crispy bits right into the center fire, wipe the steel with a lightly oiled cloth, and you are ready to convert your Arteflame into a backyard fire pit for the rest of the evening. Just be prepared to swat away your friends when they try to steal these crispy potatoes straight off the grill. Ready for more?
