This recipe for Hasselback potatoes has been my go to for family dinners and casual dinner parties for years. I first learned the technique while helping a friend prepare a holiday meal, and the thin fan like slices that crisp at the edges while staying pillowy in the center instantly felt like magic. Since then these potatoes have been served for birthdays, cozy Sunday suppers, and impromptu gatherings because they are both striking on the plate and forgiving at the oven.

What makes this version special is the balance between technique and ease. The cuts are precise enough to allow the butter to reach into the crevices, creating layers of flavor and texture, yet simple enough that you do not need special tools. The result is a potato that offers a crisp outer shell with soft, steaming interiors and a buttery aroma that makes every forkful feel indulgent. I remember one winter evening when a picky teenager who normally avoids roasted vegetables declared these the best potatoes ever and asked for one every time we make them.

Ingredients

• Russet potatoes, 4 large: Choose firm potatoes with dry skins and minimal bruising, about 10 to 12 ounces each. Russets crisp beautifully in the oven and become silky inside. Look for uniform size for even cooking.
• Unsalted butter, 4 tablespoons melted, divided: Use good quality butter for flavor, such as Plugra or Kerrygold. Melting helps the butter sink into the slices, and dividing it allows a first coat to begin browning, with a second coat for extra crisping.
• Kosher salt, 1 teaspoon: Kosher salt has larger grains which are easier to distribute evenly. If using table salt, reduce the amount by about half to avoid oversalting.
• Black pepper, 1/2 teaspoon plus more to taste: Freshly ground black pepper brings a bright counterpoint to the butter and potato starch.
• Additional salt and pepper, to taste: Finish at the table if desired so each person can season to preference.

Instructions

Prepare the oven and sheet:Arrange a rack in the middle position and preheat the oven to 425 degrees Fahrenheit. Use an unlined baking sheet so the underside of the potatoes gets direct heat for crisping, and place it on the rack before you begin cutting to allow it to warm slightly.Make the protective guide:Place one potato between two chopsticks or wooden skewers. The chopsticks act as a depth guide and prevent you from cutting all the way through, keeping the base intact. This ensures the potato fans without falling apart while baking.Cut the potatoes:Using a sharp chef knife, make vertical slices about one eighth of an inch apart along the potato, cutting straight down until your knife touches the chopstick. Keep the slices even to help the potato cook uniformly. Repeat for all potatoes, taking care to keep fingers clear and to steady the potato on the board.Butter and season:Place the potatoes on the unlined baking sheet and brush about half of the melted butter over the outside and into the slits. This step oils the edges so they crisp and allows flavor penetration into the flesh. Sprinkle with kosher salt and half a teaspoon of black pepper.Bake the first stretch:Bake for thirty minutes. This initial time softens the interior and begins the browning process. After thirty minutes, the tops should show gentle color and the edges of a few slits will begin to firm. This is the moment to separate the layers gently to allow further butter penetration.Separate and finish:Use a small knife or a spatula tip to gently nudge the slices apart to make room for more melted butter. Brush on the remaining melted butter, making sure it runs into the crevices, then return the sheet to the oven.Final bake:Bake an additional thirty to thirty five minutes, until the potatoes are deeply golden at the edges and tender when pierced with a fork. Oven times vary with potato size, so test one near the end of cooking. Remove and season to taste before serving.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to four days. To reheat and restore crisp edges, place on a baking sheet in a 400 degrees Fahrenheit oven for about ten to fifteen minutes, or until heated through and edges are crisp. Avoid reheating in the microwave for long periods, as that will make the texture soggy. If you parbake and freeze for later, cool completely, wrap each potato individually in plastic wrap, and place into a freezer safe container. To finish from frozen, bake at 425 degrees Fahrenheit for about thirty to forty minutes until hot and crisp.

Ingredient Substitutions

If you prefer olive oil over butter for a dairy free version, brush the slices with two to three tablespoons of extra virgin olive oil before baking, and finish with additional oil if needed. For a richer finish, grate one quarter to one half cup of Parmesan or aged cheddar over the potatoes during the final ten minutes of baking. If you use smaller potatoes, reduce bake times by five to ten minutes, and for very large potatoes increase the second bake by ten to fifteen minutes. Use sea salt in place of kosher salt but adjust the quantity to taste.

Serving Suggestions

Serve these potatoes alongside roast chicken, pan seared fish, or a hearty vegetarian stew. Garnish with chopped fresh parsley, chives, or a light drizzle of garlic oil for a flavor lift. For a festive plate, top with a dollop of sour cream and a scattering of crisp bacon and scallions. They also pair well with a simple green salad dressed with lemon and olive oil to cut the richness.

Cultural Background

Hasselback style originated in Sweden, named after a Stockholm restaurant where the technique gained popularity. The method transformed ordinary roasted potatoes into an elegant form, and it has been adopted around the world with many local twists. In Sweden the potatoes were often served with butter and breadcrumbs, while other cultures add cheeses or herb mixtures. The approach celebrates texture and presentation, making a humble tuber into a centerpiece.

Seasonal Adaptations

In spring and summer, top the finished potatoes with fresh herbs and a squeeze of lemon for brightness. In fall and winter, try brown butter and sage or a sprinkle of smoked paprika for warmth. Holiday variations with roasted garlic and grated nutmeg can complement richer mains, while a bright herb gremolata adds freshness for warmer months.

Meal Prep Tips

For efficient meal prep, slice and parbake the potatoes until just tender, then cool and refrigerate up to two days. When ready to serve, brush with the reserved butter or oil and finish baking to achieve crisp edges. Use shallow metal pans for the best heat conduction. Label your containers with the date and reheating instructions so you can quickly pull a special side from the fridge or freezer on busy nights.

These potatoes are a joy to make and share. The technique is simple, yet the result feels celebratory. Try them this week and make small changes to match your mood and menu. I hope they become a staple in your home as they are in mine.
