Grill-baked potatoes develop smoky skins when wrapped in foil and placed near indirect heat. If you have been wondering how to cook baked potatoes on a grill, the process is simpler than you think. You get a crispy outside and a fluffy inside without turning on your oven. This method works great for summer cookouts or any night you want to avoid heating up the kitchen.
You do not need fancy equipment. Just potatoes, foil, oil, salt, and a grill. The key is controlling the heat and wrapping the potatoes correctly. Let me walk you through every step so you can serve perfect grilled baked potatoes every time.
Why Grill Baked Potatoes Instead Of Using The Oven
Grilling adds a subtle smokey flavor that an oven cannot replicate. The direct flame chars the skin slightly, giving it a rustic texture. Plus, you free up oven space for other dishes. It is also faster in many cases because the grill gets hotter than most home ovens.
Another advantage is cleanup. Foil packets mean no baking sheet to scrub. You can even cook the potatoes alongside your main protein, like steak or chicken, for a complete meal. This makes it a practical choice for busy weeknights or backyard parties.
Choosing The Right Potatoes For Grilling
Not all potatoes work equally well for this method. Russet potatoes are the best choice because they have thick skins that hold up to heat and starchy interiors that become fluffy. Yukon Gold potatoes also work, but they are denser and less fluffy.
Avoid waxy potatoes like red or new potatoes. They do not break down the same way and can turn gummy. Look for potatoes that are similar in size so they cook evenly. Medium-sized russets, about 8 to 10 ounces each, are ideal.
How To Prepare Potatoes Before Grilling
Start by scrubbing the potatoes under cold water to remove dirt. Pat them dry with a clean towel. Prick each potato several times with a fork. This allows steam to escape and prevents them from bursting on the grill.
Rub the skins lightly with olive oil or vegetable oil. This helps the salt stick and promotes a crispy skin. Season generously with coarse salt. You can also add black pepper, garlic powder, or dried herbs at this stage.
Wrapping Potatoes In Foil The Right Way
Use heavy-duty aluminum foil for best results. Tear off a piece large enough to wrap each potato completely. Place the potato in the center of the foil. Bring the two long sides together and fold them over several times to create a tight seal. Then fold the ends inward.
Do not wrap too tightly. Leave a small air pocket around the potato. This allows heat to circulate and cook the potato evenly. If you wrap too tight, the potato may steam instead of bake, resulting in a soggy skin.
How To Cook Baked Potatoes On A Grill
Now we get to the main event. Set up your grill for indirect heat. For a gas grill, turn on one side to medium-high and leave the other side off. For a charcoal grill, bank the coals to one side. You want the temperature inside the grill to be around 400°F to 425°F.
Place the foil-wrapped potatoes on the cooler side of the grill, away from the direct flame. Close the lid. Let them cook for 45 to 60 minutes, depending on size. Flip the potatoes halfway through using tongs to ensure even cooking.
Check for doneness by inserting a skewer or knife into the thickest part. It should slide in easily with no resistance. If it does not, continue cooking for another 10 minutes and check again. Do not rush this step.
How To Get Crispy Skins On Grilled Potatoes
If you prefer extra crispy skins, unwrap the potatoes during the last 10 minutes of cooking. Place them directly on the grill grates over indirect heat. This allows the foil to come off and the skin to dry out and crisp up.
You can also brush the unwrapped potatoes with a little more oil and sprinkle with salt before the final crisping. Watch them closely to avoid burning. The skins should turn golden brown and slightly blistered.
Serving Suggestions For Grilled Baked Potatoes
Once the potatoes are done, let them rest for 5 minutes. This allows the steam to settle and makes them easier to handle. Cut a slit down the center and squeeze the ends to open them up. Add butter, sour cream, cheese, chives, or bacon bits.
You can also serve them as a side dish with grilled meats, fish, or vegetables. For a main course, load them with chili, pulled pork, or shredded chicken. The possibilities are endless.
Common Mistakes When Grilling Baked Potatoes
Many people make the same errors. One is wrapping the potatoes too tightly, which causes steaming. Another is placing them over direct heat, which burns the outside before the inside cooks. Always use indirect heat.
Skipping the fork pricks is also a problem. Without vent holes, pressure builds up and the potato can explode. Also, do not use thin foil. It tears easily and lets steam escape, drying out the potato.
How To Fix Undercooked Potatoes
If you cut into a potato and find it hard in the center, do not panic. Simply rewrap it in foil and return it to the grill for another 15 to 20 minutes. You can also microwave it for 2 to 3 minutes to finish cooking, but this sacrifices the crispy skin.
To avoid this issue in the future, choose potatoes of similar size and check them with a thermometer. The internal temperature should reach 205°F to 210°F for a fully cooked, fluffy texture.
Variations On Grilled Baked Potatoes
You can customize this basic method in many ways. Try adding garlic butter, rosemary, or Parmesan cheese before wrapping. Some people like to slice the potato partially and insert cheese or bacon inside before grilling.
For a faster version, cut the potatoes into wedges or slices before wrapping. This reduces cooking time to about 20 to 30 minutes. Just be careful not to overfill the foil packets. You want even cooking.
Using A Grill Basket Or Cast Iron Skillet
If you do not have foil, you can use a grill basket or a cast iron skillet. Place the seasoned potatoes directly in the basket or skillet and cook over indirect heat. Turn them occasionally for even browning. This method gives you a crustier skin.
Cast iron retains heat well and can go from grill to table. Just be sure to oil the skillet to prevent sticking. This works best for smaller potatoes or potato halves.
How To Store And Reheat Leftover Grilled Potatoes
Leftover grilled baked potatoes keep well in the refrigerator for up to 4 days. Store them in an airtight container or wrap them in foil. To reheat, place them back on the grill for 10 to 15 minutes, or use an oven at 350°F.
You can also reheat them in the microwave, but the skin will become soft. For best results, slice the potato and pan-fry it in a little oil until crispy. This works great for breakfast hash.
Can You Freeze Grilled Baked Potatoes
Yes, you can freeze them. Let the potatoes cool completely, then wrap each one tightly in plastic wrap and foil. Place them in a freezer bag. They will keep for up to 3 months. Thaw in the refrigerator overnight before reheating.
Freezing works best if you plan to use them in soups or casseroles. The texture changes slightly after freezing, so they may not be as fluffy for direct eating.

Do You Have To Wrap Potatoes In Foil For Grilling
No, you can grill potatoes without foil, but they will cook faster and have a drier skin. Foil helps them steam and become fluffy inside. For crispy skin, unwrap them at the end.
Can You Grill Baked Potatoes On A Gas Grill
Yes, gas grills work perfectly. Just set one burner to medium-high and leave the other off. Place the potatoes on the unlit side and close the lid.
What Temperature Should Grilled Baked Potatoes Reach
The internal temperature should be 205°F to 210°F. Use an instant-read thermometer to check. This ensures the starch is fully cooked and the texture is fluffy.
How Do You Keep Grilled Potatoes From Burning
Use indirect heat and flip them halfway through. If the grill runs hot, reduce the temperature to 375°F. Also, avoid placing them too close to the flame.
Final Tips For Perfect Grilled Baked Potatoes
Always preheat your grill for at least 10 minutes before adding the potatoes. This stabilizes the temperature. Do not overcrowd the grill; leave space for heat to circulate.
Experiment with different seasonings. Smoked paprika, cumin, or chili powder add depth. You can also brush the potatoes with melted butter before serving for extra richness.
Remember that grill temperatures vary. Get to know your grill and adjust cooking times accordingly. A grill thermometer helps you maintain consistent heat.
With practice, you will master how to cook baked potatoes on a grill. The smoky flavor and crispy skin make it worth the effort. Enjoy your perfectly grilled potatoes with your favorite toppings.
