You've got the burgers handled, but there's one side dish that often trips up even pros: knowing how long to grill potatoes. When the flames are hot and the guests are hungry, guesswork can mean a hard center or a burned outside. The short answer? It depends on the cut, but a few simple techniques guarantee tender, smoky spuds every time.
Grill Times at a Glance
Before you fire up the coals, decide which route you’re taking. Timing varies between thin slices, hearty wedges, and whole baby potatoes. Use this cheat sheet as your starting point:
| Cut | Best Prep | Total Grill Time |
|---|---|---|
| Thin slices (1/4-inch) | Tossed in oil and seasoned | 8–12 minutes |
| Wedges (1-inch) | Parboiled for 8–10 minutes | 15–20 minutes |
| Baby potatoes | In a foil packet with oil or butter | 25–30 minutes |
The Foolproof Method: Parboiled Wedges
For the most consistent results, professionals recommend parboiling your potatoes before grilling. It sounds fancy, but it simply means boiling them briefly until they just start to soften. This ensures the center cooks all the way through without scorching the outside.
- Scrub and cut russet or Yukon Gold potatoes into evenly sized wedges, about 1-inch thick.
- Bring a large pot of heavily salted water to a boil. Add the wedges and cook for 8 to 10 minutes. You want a knife to meet just a little resistance.
- Drain them thoroughly in a colander. Let them sit for a couple of minutes so excess moisture evaporates.
- Toss the warm potatoes with 2 tablespoons of olive oil, a teaspoon of garlic powder, and a sprinkle of smoked paprika.
- Place them on a clean grill grate over direct medium heat, around 375°F to 400°F.
- Grill for 7 to 10 minutes per side, flipping once, until they are deeply golden and have developed those beautiful char marks.
If you're slicing them thin for quick street-cart-style potatoes, you can skip the boiling step. Just coat 1/4-inch rounds with oil and lay them directly over medium-high heat for 4 to 5 minutes per side.
How to Know They’re Done
The timer is your guide, but the fork is the judge. Slide a sharp paring knife into the thickest piece. The potato should yield like soft butter with zero resistance. If there is a hard core in the center, move it to a cooler part of the grill, cover, and give it a few extra minutes to steam through.
🔥 Note: Keep one side of your grill free or turn one burner to low. If flare-ups occur or the potato edges are browning too quickly, moving the pieces to this cooler zone lets the insides finish cooking without any burnt flavors.
With these time checks and the fork test in your back pocket, you can grill potatoes without a second thought. Serve them hot, with a sprinkle of flaky salt, and watch them disappear.
