There’s nothing quite like the flavor of potatoes cooked over open flame. This method transforms simple ingredients into something extraordinary with smoky depth and crisp texture.
I developed this technique after years of experimenting with heat zones and timing. The result is golden centers with edges that shatter at the slightest touch.

The potatoes must be Russet—their high starch content yields that coveted crisp exterior and fluffy interior. Whole Foods or Trader Joe’s often stock organic options with ideal dryness for roasting. Select potatoes that feel firm with no green spots, and avoid pre-cut versions (they oxidize too quickly). For best results, cut them uniformly to ensure even cooking over the grill’s variable heat zones.
No smoked paprika? Regular paprika plus a pinch of liquid smoke (just 1/8 tsp) works in a pinch. Fresh rosemary or thyme can replace dried at triple the amount, but dried is more reliable for consistent flavor. Vegetable oil can sub for olive oil if that’s what you’ve got, though you’ll lose some depth. The cayenne is purely optional—omit it for a milder dish.
Pre-cut potatoes can sit in cold water up to 2 hours before grilling to prevent browning. Leftover roasted potatoes keep 4-5 days in the fridge—reheat on a skillet to revive crispness. This dish doesn’t freeze well, as the texture softens upon thawing.

Step-by-Step Instructions for Grill Roasted Potatoes
Master the technique for perfectly charred, aromatic potatoes with this reliable method.
Step 1: Prepare and Season the Potatoes
Begin by scrubbing the 2 lb Russet Potatoes thoroughly under cool water to remove any dirt. Cut them into uniform 1-inch chunks—this ensures even cooking and consistent texture throughout. Larger pieces won’t cook through properly, while smaller ones may burn before becoming tender.
In a large bowl, combine the potatoes with 2 tbsp Extra-Virgin Olive Oil, 1.5 tsp Kosher Salt, 1 tsp Freshly Ground Black Pepper, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Smoked Paprika, 1 tsp Dried Rosemary (crushed between your fingers), 0.5 tsp Dried Thyme, and 0.25 tsp Cayenne Pepper. Toss until every piece is evenly coated with the seasoning blend.
Step 2: Preheat and Prepare the Grill
Set up your grill for indirect heat by banking the coals to one side or turning off one set of burners on a gas grill. Preheat to medium-high heat (about 400°F). This two-zone setup allows you to sear the potatoes directly over the heat before moving them to finish cooking indirectly.
Clean the grates thoroughly with a grill brush to prevent sticking. Lightly oil the grates by folding a paper towel into a small square, dipping it in the remaining 1 tbsp Extra-Virgin Olive Oil, and using tongs to rub it over the hot grates. This creates a non-stick surface for the potatoes.
Step 3: Grill the Potatoes to Perfection
Arrange the seasoned potatoes in a single layer directly over the heat. Close the lid and cook for 10-12 minutes, turning occasionally, until they develop deep char marks and the edges begin to crisp. Watch for pieces that might be cooking faster and move them to the cooler side of the grill if needed.
Once charred, move all the potatoes to the indirect heat side of the grill. Close the lid and continue cooking for 15-20 minutes, turning every 5 minutes, until they’re golden brown throughout and a knife slides in easily. The potatoes are done when they’re crispy on the outside and tender, fluffy inside.
Step 4: Finish and Serve
Transfer the potatoes to a serving platter. If you prefer extra crispiness, you can return them to direct heat for 1-2 minutes per side. Be vigilant during this final crisping step—potatoes can go from perfectly charred to burnt quickly at this stage.
Let them rest for 5 minutes before serving to allow the starched centers to set slightly. This brief rest ensures the seasoning adheres better to each piece. Serve immediately while hot and crispy for the best texture and flavor.
Pro Tips For Making Grill Roasted Potatoes
- Parboil First: Toss the russets in boiling water for 8-10 minutes before grilling—this softens the centers so they cook through without burning on the outside.
- Cut Evenly: Slice the potatoes into 1-inch chunks, no smaller, or the edges will char before the insides get tender.
- Skip the Overcrowding: Spread the potatoes in a single layer on the grill; piling them up makes them steam instead of crisp.
- Double the Oil: Use 3 tablespoons of olive oil—enough to fully coat the potatoes so the salt and garlic powder actually stick.
Dietary Considerations for These Flavors
Naturally Vegan
This dish is inherently vegan—no animal products used at all. The Russet Potatoes and Extra-Virgin Olive Oil provide all the richness needed, while our spice blend delivers bold flavor without dairy or meat. Perfect for plant-based diets. 🌱
Gluten-Free Friendly
All ingredients are naturally gluten-free, so this works beautifully for anyone avoiding wheat. Just double-check your spice labels—some brands add anti-caking agents that contain gluten. I always use Penzeys for their pure spices.
Allergen Notes
The only potential allergen here is olive oil for those with tree nut allergies. If needed, substitute avocado oil or vegetable oil without affecting flavor. This keeps the dish safe for most dietary restrictions.
Low-Carb Adaptation
To reduce carbs, swap Russet Potatoes for 1.5 lb cauliflower florets cut into 1-inch pieces. Use the same seasoning and grilling method—they’ll char beautifully with a slightly different texture. 💡
Oil-Free Option
For oil-free cooking, replace Extra-Virgin Olive Oil with vegetable broth. Toss the potatoes in ¼ cup broth before seasoning. They won’t crisp as much but will still absorb smoky flavor from the grill.
Sodium Control
To reduce sodium, cut the Kosher Salt by half and boost flavor with 1 tbsp nutritional yeast or 1 tsp lemon zest. The smoked paprika and herbs provide plenty of taste without excess salt.

Frequently Asked Questions
Can I use other potato varieties?
Russets work best for crisp edges, but Yukon Golds are a good alternative. They’ll be creamier with slightly less crunch. Avoid waxy potatoes like red or new potatoes—they don’t crisp well.
Why use two-zone grilling?
Two-zone cooking lets you sear over direct heat first, then finish gently. This prevents burning while ensuring the centers cook through completely. It’s the secret to perfect crispy outside, fluffy inside results.
How do I prevent sticking?
Clean and oil the grates thoroughly before cooking. Use medium-high heat (400°F) and avoid moving the potatoes too soon. Let them develop a crust before turning.
Can I make these ahead?
Par-cook the potatoes for 8 minutes in the microwave, then cool and refrigerate. Finish on the grill when ready to serve. They’ll still get smoky flavor but cut grilling time in half.
