Hasselback Potato Recipe on the Grill: Smoky Crisp Layers

Grilling transforms hasselback potatoes into something extraordinary with smoky depth and crisp edges. I first discovered this method at a local BBQ competition where the aroma of wood-fired potatoes drew a crowd.

The key is thin, even slices that fan open as they cook, allowing smoke and heat to penetrate every layer. A light brushing of oil and a sprinkle of salt before grilling ensures crispy edges while the inside stays tender.

What emerges from the grill is a potato with perfectly charred, smoky layers and a fluffy center. The presentation alone makes it a standout side dish for any cookout.

This technique works with any firm potato variety and pairs beautifully with grilled meats or as a vegetarian centerpiece.

Potato selection is critical. Yukon Golds offer the perfect balance of waxy texture and buttery flavor, while Russian Bananas hold their shape beautifully. Seek out organic options at Whole Foods or Trader Joe’s for superior quality. The wood chips should be natural, untreated—avoid anything with chemicals or additives. Fresh rosemary makes a noticeable difference, so grab a bunch from the produce section rather than dried.

No Yukon Golds? Red potatoes work well too, though they’re slightly waxier. Short on time? Skip the wood chips and use a smoker box or even a handful of chips wrapped in foil with holes poked in it. The butter can be replaced with olive oil for a dairy-free version. Dried rosemary at half the amount works in a pinch, but fresh is ideal for that vibrant, piney aroma.

Store potatoes in a cool, dark place for up to 2 weeks. Wood chips keep indefinitely in a sealed container. Leftovers reheat well—pop them back on the grill or in a 400°F oven for 10 minutes to revive the crispiness.

Step-by-Step Instructions for Hasselback Potatoes on the Grill

Master the technique for perfectly crisp, smoky layers every time with this method.

Step 1: Prepare the Grill and Wood Chips

Soak the 1 cup Wood Chips in water for 30 minutes to prevent them from burning too quickly. While they soak, clean your grill grates thoroughly and preheat the grill to medium-high heat (about 400°F). You want a consistent, even heat for proper cooking and smoke infusion.

Once the grill is hot, drain the wood chips and place them in a smoker box or wrap them in heavy-duty foil with holes poked in the top. Position this directly over the heat source. Close the lid and allow the wood chips to begin smoking—this will create the smoky depth these potatoes are known for.

Step 2: Prepare the Yukon Gold Potatoes

Wash and scrub the 2 lb Yukon Gold Potatoes thoroughly, leaving the skins on for texture and flavor. Place each potato on a cutting board and use a sharp knife to make thin, even slices along the top, stopping just before you cut through completely—this creates the signature hasselback accordion effect.

To prevent the knife from slicing all the way through, place chopsticks on either side of the potato as a guide. Brush the potatoes generously with 2 tbsp Extra-Virgin Olive Oil, ensuring the oil gets between each slice. Season evenly with 1.5 tsp Kosher Salt and 1 tsp Freshly Ground Black Pepper.

Step 3: Infuse the Oil and Grill the Potatoes

In a small bowl, combine the remaining 1 tbsp Extra-Virgin Olive Oil with the minced 4 cloves Garlic Cloves, chopped leaves from the 2 whole Fresh Rosemary Sprigs, and 0.5 tsp Smoked Paprika. This aromatic oil will add layers of flavor as the potatoes cook.

Place the potatoes directly on the grill grates, cut-side up. Grill for 20-25 minutes, basting occasionally with the garlic-rosemary oil. The edges of the slices should begin to crisp and turn golden brown. If the potatoes begin to char too quickly, move them to a cooler part of the grill.

Step 4: Finish with Butter and Parmesan

Once the potatoes are nearly tender (a knife should slide in with slight resistance), brush them with the melted 2 tbsp Unsalted Butter. This adds richness and helps achieve a deeper golden color. Continue grilling for another 5-10 minutes until the potatoes are fully tender and the edges are crisp.

Transfer the potatoes to a serving platter and, while still hot, sprinkle evenly with the 0.25 cup Grated Parmesan Cheese, if using. The residual heat will melt the cheese slightly, creating a delicious, savory finish. Let them rest for 5 minutes before serving to allow the flavors to meld.

Pro Cooking Tips for Perfect Results

Chopstick Trick

Place two chopsticks parallel to the potato on your cutting board as guides. This prevents the knife from cutting all the way through, creating perfect 1/8-inch slices that fan open beautifully on the grill. I learned this trick from a French chef—simple but game-changing. 💡

Heat Zoning

Set up your grill with direct heat on one side and indirect heat on the other. Start potatoes over direct heat to crisp the edges, then move to indirect heat to cook through without burning. A dual-zone grill setup gives you complete control.

Oil Application

Use a pastry brush to apply oil between each slice—this ensures every surface gets coated. I prefer extra-virgin olive oil for its high smoke point and flavor. Don’t skimp here; those crispy edges depend on thorough coverage.

Smoke Timing

Add wood chips only after the potatoes are on the grill. This prevents the smoke from dissipating before it can infuse the potatoes. Hickory chips give a robust flavor, while applewood offers a sweeter touch. Soak them for 30 minutes to extend smoke time.

Butter Baste

Melt the unsalted butter with a sprig of rosemary before basting. This infusion adds aromatic depth to the final layers. Baste during the last 10 minutes of cooking to prevent burning. 🌿

Resting Period

Let the potatoes rest for 5-10 minutes after grilling. This allows the starched center to set, making them easier to handle. The carryover heat also ensures the parmesan melts perfectly.
