Hasselback. Because who doesn’t like crispy-edged potatoes?

Cathy Barrow

THE WASHINGTON POST – Hasselback potatoes are frequent offerings on Midwestern tables and have enjoyed spikes in popularity through the years.

Said to have originated at the Hasselbacken inn in Sweden, these buttery treats show up now across the country and, if the Internet is any indication, all around the world.

They are potato perfection, with crispy edges, creamy centres and toasty bottoms. Hasselbacking requires a sharp knife, patience and ingenuity, all of which I’m willing to devote to a very special side for Thanksgiving dinner. When I’m not in charge of all the dishes, but instead have been asked to bring just one, I want it to be glorious.

The key to a Hasselbacked potato is making extremely slim slices through most, but not all, of the potato. When done properly, they are so thin the potato will look like a Slinky. While cooking, the slices fan open, allowing the flavoured butter to permeate the centre of the potato. As the butter melts, it pools on the bottom of the pan, roasting the potato from the bottom up. It’s more than just a delicious recipe – it’s a beautiful presentation.

The thinner the potato is sliced, the snappier the crispy edges. To slice only part of the way through the potato is challenging but not impossible.


I employ the Two-Chopstick-Method: Rest the potato lengthwise between two chopsticks and slice downward. The chopsticks will keep the knife from slicing all the way through, so that the potato remains intact.

Two identical wooden spoons will also work, with the potato resting on the parallel handles.

And I’ve recently learnt there is a Hasselback tool (more than 12 versions available online!) – a wooden block with a scooped out centre into which the potato nestles. Some versions of the tool have a wire topper that fits over the potato and guides the knife.

A friend told me that her new mother-in-law gave her a Hasselback tool when she married. “My son likes Hasselback potatoes” was her only comment. Message received!

Once sliced, the Hasselback technique calls for butter to be pushed between the slices. This is a marvelous idea but nearly impossible to achieve.

Instead, coat the top of the potato thickly with the herbed butter, pushing it between the slices to the best of your ability. It will get there in the oven, so don’t worry. Be very generous with the finely chopped herbs that flavour the butter. It should smell spectacular while cooking. For extra crispy bits, I mixed panko crumbs into the butter. When the butter melts, those crumbs attach to the edges of the potato slices, and the crunch factor is amplified.

To effectively serve many people, rather than using full-size potatoes, this recipe can be made with small fingerling-shaped spuds. I combined sweet potatoes and the whole rainbow of potato hues – purple, red and gold – often packaged together in the produce department at many grocery stores. These smaller potatoes take up less room on the plate, which is an important consideration at big events when so many side dishes are competing for our attention.

I packed my largest cast-iron pan with these small potatoes, all Hasselbacked. After time in the oven, they were deliciously crispy on the top. The heat from the pan bronzed the bottom of the potatoes and kept the dish hot for a long time after removing it from the oven. The smaller potatoes took about an hour, while full-size potatoes baked for 90 minutes or more. Time is less predictable with varying sizes, so use a fork to poke the centre of the largest potato, looking for a soft and yielding texture as an indication of doneness.

I’ve been playing with root vegetables and the Hasselback technique. Try it with small white turnips, parsnips and carrots.

It’s amenable to celeriac and rutabaga, too.

But when it’s time for the big feast, Hasselback potatoes are a winning showstopper you’ll be delighted to carry to your feast.


12 servings

Leftover hasselback potatoes are a superb start to any hash and a nice breakfast, served with a fried egg.

MAKE AHEAD: The seasoned butter and panko may be made three months ahead and frozen. The dish may be made one day ahead; it does not freeze well. Reheat at 400 degrees for 15 to 20 minutes.


4 pounds russet potatoes or sweet potatoes

4 ounces (8 tablespoons) unsalted butter, softened

2 tablespoons minced fresh chives

2 tablespoons minced fresh flat-leaf parsley

1 tablespoon minced fresh thyme leaves

1 tablespoon minced fresh sage leaves

1 garlic clove, finely grated

1 teaspoon kosher or sea salt

1/2 teaspoon freshly ground black pepper

1/2 cup panko


Scrub the potatoes and peel, if desired. To “hasselback,” place a potato on a cutting board. Snugly arrange two chopsticks or two identical round handles of wooden spoons at either side of the potato. (If needed, slice a slim piece from the bottom of the potato so that it will sit squarely.)

Using a sharp knife, make 1/8-inch slices along the length of the potato, using the chopsticks as a brake, so that while slicing, the blade stops before cutting all the way through the potato.

Be aware of the ends of the potatoes, taking care not to slice all the way through. When finished, the top of the potato will fan out slightly. Place the potatoes in a bowl of ice water to keep them from browning while cutting the others.

In a medium bowl, stir together the softened butter, chives, parsley, thyme, sage, garlic, salt and pepper until well blended. Fold in the panko. (At this point, the butter may be shaped into a roll or stick and refrigerated for up to one week or frozen for up to three months.)

Preheat the oven to 400 degrees with the rack in the middle.

Thoroughly dry the potatoes. Using your fingertips, slather the potatoes with about half of the buttery crumbs, taking time to press the mixture between the slices. This will be challenging as the potato will be stiff and uncooperative. Once buttered, place the potatoes in a baking pan, casserole dish or cast-iron skillet, fitting them snugly in one layer. Place a piece of parchment over the potatoes and cover the dish with foil, sealing it well.

Bake for 30 minutes, remove the foil and parchment and plunge a fork into the centre of the largest potato. It should yield and be soft but not collapse.

If it is still hard, replace the parchment and foil and bake for an additional 15 minutes. If softened, draw the tines of the fork along the top of each potato to fan the slices. Plop nuggets of the remaining butter-crumb mixtures over the top of each potato.

Bake, uncovered, an additional 15 to 20 minutes, until the potatoes are soft and yielding and slightly crisped on the surface. Spoon the herbed butter over the top of the potatoes and serve.
