Tender Grilled Hasselback Potatoes

Something about the way butter sizzles between those thin potato slices on a hot grill makes everyone gather around like it is a performance. My neighbor Dave once leaned over the fence just to ask what smelled so good, and I ended up tossing an extra potato on for him without hesitation. These Hasselback potatoes turned a regular Tuesday cookout into the kind of evening where nobody wanted to go inside.

I burned my first batch badly because I cranked the grill to high and walked away to mix a drink. The second attempt, with the heat dialed back and foil doing its job, came out golden and crisp with edges that snapped like a potato chip. My sister in law now requests them every single time we host, and I have stopped arguing about it.

Ingredients

• 4 medium russet or Yukon gold potatoes: Russets give you that fluffy center while Yukon golds stay creamier throughout.
• 4 tbsp unsalted butter, melted: Unsalted lets you control the seasoning, and it browns beautifully on the grill.
• 2 cloves garlic, finely minced: Fresh garlic matters here since it toasts slightly in the butter between the slices.
• 1 tbsp fresh parsley, chopped: Adds a bright color and mild freshness that balances the richness.
• 1 tsp fresh thyme leaves: Thyme holds up to heat better than most herbs and brings a subtle earthiness.
• 1/2 tsp kosher salt: Coarse salt gets into the cuts and seasons from the inside out.
• 1/4 tsp freshly ground black pepper: A little goes a long way but skip it and you will notice something missing.
• 2 tbsp grated Parmesan cheese (optional): Melts into the crevices and forms tiny crispy pockets of salty goodness.
• 1 tbsp chopped chives (optional): A mild onion finish sprinkled on at the very end.

Instructions

Get the grill going:

Preheat your grill to medium high, around 400 degrees Fahrenheit, and give the grates a good brush while they heat up so nothing sticks later.

Prep the potatoes:

Wash and scrub each potato thoroughly, then place it between two wooden spoons or chopsticks so your knife stops before cutting all the way through. Slice crosswise at eighth inch intervals and try to keep the cuts even so they cook uniformly.

Mix the garlic herb butter:

Stir together the melted butter, minced garlic, parsley, thyme, salt, and pepper in a small bowl until it smells like a garden in July.

Baste generously:

Brush the butter mixture all over each potato, using your fingers or the brush tip to gently work it down between the slices where the real magic happens.

Wrap in foil:

Wrap each potato loosely in a double layer of foil, leaving the top slightly open so steam escapes and some crisping can begin.

Grill low and slow:

Place the potatoes directly on the grill, close the lid, and let them cook for 35 to 40 minutes, brushing with extra butter every ten minutes or so. Unwrap the foil for the last five to ten minutes to let those edges turn golden and crisp.

Serve with flair:

Transfer to a warm platter, shower with Parmesan and chives if using, and get them to the table fast because they disappear quickly.

Pin it

One Fourth of July I made a double batch and set them on a tray beside the burgers, and they vanished before the meat did. People kept picking them up with their fingers, burning their tips, and going back for another anyway.

Getting That Perfect Fan Shape

The visual payoff of Hasselback potatoes is the fanned out look, and achieving it is easier than people think. The key is using potatoes of a similar size so they all finish at the same time and the slices spread evenly during cooking.

Smoky Variations Worth Trying

A pinch of smoked paprika in the butter mixture adds a deep campfire flavor that works beautifully alongside grilled chicken or ribs. I have also swapped the thyme for rosemary on a whim and been completely won over by the piney aroma.

Serving and Pairing Thoughts

These potatoes stand on their own but truly shine next to something with a little char or a bright acidic salad. A cold glass of Sauvignon Blanc cuts through the butter perfectly, and even sparkling water with lemon does the job nicely.

• Let them rest for two minutes after coming off the grill so the butter settles into the layers.
• A dollop of sour cream on the side is never a bad idea.
• Leftovers reheat surprisingly well in a hot oven for about ten minutes.

Some recipes are just food, but these potatoes have a way of pulling people together around the grill and keeping them there. Make them once and they will follow you to every cookout for years.

Recipe FAQs

→ What are Hasselback potatoes?

Hasselback potatoes are potatoes that have been sliced crosswise in thin, even intervals without cutting all the way through, creating an accordion-like shape. This technique allows butter and seasonings to seep between the slices while cooking, resulting in a crispy exterior and soft, tender interior.

→ What type of potatoes work best for grilling Hasselback style?

Medium russet or Yukon gold potatoes are ideal for this preparation. Russets offer a fluffier interior with crispier edges, while Yukon golds provide a creamier, buttery texture throughout. Choose firm, evenly shaped potatoes for uniform slicing and cooking.

→ How do I prevent cutting all the way through the potato?

Place each potato between two wooden spoons or chopsticks on your cutting board. The handles act as a guard, stopping your knife before it reaches the bottom. Slice at roughly 1/8-inch intervals for the best fan-like effect and even crisping.

→ Can I make these dairy-free?

Yes, simply substitute the unsalted butter with a good-quality vegan butter or olive oil. The garlic and herb flavors carry through beautifully either way. If using olive oil, consider adding a small pinch of smoked paprika for extra depth on the grill.

→ What temperature should the grill be for cooking Hasselback potatoes?

Preheat your grill to medium-high heat, approximately 400°F (200°C). This temperature allows the potatoes to cook through evenly in the foil while developing a nice crisp exterior when you remove the foil for the final 5–10 minutes of grilling.

→ What main dishes pair well with grilled Hasselback potatoes?

These potatoes complement grilled steaks, chicken, ribs, or fish beautifully. They also work as a hearty side for vegetarian mains like grilled portobello mushrooms. A crisp Sauvignon Blanc or a light lager makes an excellent beverage pairing.
