This version of Hasselback potatoes has been my go-to way to dress up humble spuds whenever I want something that looks fancy but takes almost no extra effort. I first made these on a chilly autumn evening when friends were coming over for dinner and I wanted a side that could be prepared ahead and finished in the oven while the main course rested. The thin fan-like slices let the butter and seasoning seep in while creating more surface area for crisping, giving each bite a contrast of golden, crunchy edges and soft, fluffy interior.

I remember the first time I served them: my neighbor’s eyes lit up at the presentation, and even the kids reached for seconds despite having been politely full. The texture is the real star — imagine a small potato accordion where every fold is a little crunch, and the inside is pillowy and smooth. Using simple pantry ingredients like unsalted butter, kosher salt, and fresh-cracked pepper keeps the flavor pure and lets the potato take center stage. These are perfect for holiday spreads, weeknight dinners, or as a make-ahead component that reheats beautifully.

Ingredients

• Russet potatoes (4 large): Choose even-sized, firm potatoes with dry skin for uniform cooking. I prefer russets for their high starch content — they crisp nicely on the outside while staying fluffy inside. Avoid green or soft spots; if available, pick baking-grade russets from your grocery's produce section.
• Unsalted butter (4 tablespoons), melted: Melted butter is brushed into the slices and over the surface to encourage browning and flavor. Using unsalted gives you precise control over seasoning; if you only have salted butter, reduce added salt accordingly.
• Kosher salt (1 teaspoon) + extra to taste: Kosher salt provides clean seasoning that distributes evenly. I use Diamond Crystal for lighter hand, but table kosher brands work fine — taste as you go.
• Black pepper (1/2 teaspoon), freshly cracked: Freshly cracked black pepper adds bright, peppery heat. Grind just before use for best aroma.
• Salt and pepper, to taste: Final seasoning after baking lets you adjust to individual preference; flaky finishing salt is a lovely option for texture and pop.

Instructions

Prepare and preheat: Arrange the oven rack to the middle position and preheat the oven to 425°F. Line a baking sheet with a thin layer of oil or use the sheet unlined for maximum crisp — unlined creates better conduction but requires care when removing. Set out a basting brush and a sharp chef’s knife. Pat the potatoes dry so the butter adheres and the skins crisp. Score the potatoes: Place one potato between two chopsticks or wooden skewers to act as guides. With a sharp knife make vertical cuts about 1/8 inch apart, slicing straight down until the knife meets the chopstick to avoid cutting through the base. This creates the signature accordion effect while keeping the potato intact. Repeat with all potatoes, keeping slices even for uniform cooking. Butter and season: Place the potatoes on the unlined baking sheet and use a basting brush to coat with about half of the melted butter, ensuring some butter reaches between the slits. Sprinkle evenly with 1 teaspoon kosher salt and 1/2 teaspoon freshly cracked black pepper. The initial butter locks in moisture and promotes browning during the first stage of baking. First bake: Bake the potatoes at 425°F for 30 minutes. The goal in this stage is to begin cooking through and set the shapes so the edges lift slightly. You should see the outer edges start to brown and the potato interiors begin to soften; a skewer should meet little resistance at this point. Separate slices and baste: After 30 minutes, carefully use a knife or two forks to gently pry the slices open; this increases airflow and creates more surface area to crisp. Brush on the remaining melted butter, making sure it soaks down between the slits as much as possible without collapsing the potato. Final bake to crisp: Return the sheet to the oven and bake another 30–35 minutes, or until the exterior is deeply golden and crisp while the inside is tender when pierced with a knife. Cooking time will vary with potato size; larger potatoes may need an extra 5–10 minutes. Remove from oven and season with additional salt and pepper to taste before serving.

Storage Tips

Cool any leftovers to room temperature but no longer than two hours, then store in an airtight container in the refrigerator for up to 3 days. For best texture, reheat on a baking sheet in a preheated 375°F oven for 8–12 minutes until the edges regain crispness. For longer storage, fully bake the potatoes, cool completely, wrap individually in foil, and freeze for up to 3 months. Thaw overnight in the refrigerator and re-crisp in the oven before serving. Avoid storing while still steaming; excess moisture will soften the slices.

Ingredient Substitutions

If you need to swap ingredients, use Yukon Gold potatoes for a creamier interior — they will hold their shape slightly better but produce less crispness than russets. For a dairy-free option, substitute melted vegan butter or neutral oil like avocado oil; allow a little more oil between the slices to mimic butter’s browning. If you like herbs, add 1 teaspoon dried rosemary or 1 tablespoon fresh chopped rosemary mixed into the melted butter. For a lower-sodium version, reduce added salt and finish with a small pinch of flaky sea salt on those who want it.

Serving Suggestions

Serve warm as a side to roasted chicken, pan-seared steak, or a holiday turkey. Garnish with chopped fresh chives, parsley, or a sprinkle of grated Parmesan for a salty finish. For a decadent twist, after the final bake tuck a thin slice of garlic butter between a couple of the slits or sprinkle shredded Gruyère during the last 5 minutes so it melts without burning. These also pair beautifully with a crisp green salad and a bright vinaigrette to balance the richness.

Cultural Background

The Hasselback method originated in Sweden in the mid-20th century and is named after the Hasselbacken restaurant in Stockholm where the technique was popularized. The concept — slicing thinly to increase surface area — reflects Scandinavian sensibilities of taking simple ingredients and elevating them through technique. Over time the approach spread internationally because it visually impresses while remaining approachable for home cooks, fitting both Nordic tradition and modern comfort-food tables.

Seasonal Adaptations

In winter, add 1 teaspoon of smoked paprika to the butter for warmth and earthiness. In spring or summer, top with fresh lemon zest and chopped herbs like tarragon and parsley to brighten the dish. For holiday feasts, tuck slices of cranberry-chile chutney on the side or drizzle a rosemary-infused brown butter over the finished potatoes. These small switches allow the same base technique to feel at home during any season.

Meal Prep Tips

For make-ahead convenience, score and par-bake the potatoes for the initial 30 minutes, cool, and refrigerate in an airtight container for up to 24 hours. When ready to serve, separate the slices, baste with the remaining butter, and finish in a hot oven for 30–35 minutes to restore and amplify crispness. Use rimmed baking sheets and allow space between potatoes so hot air can circulate for even browning.

These Hasselback potatoes are a humble technique that creates a memorable side — elegant enough for guests, simple enough for weeknights. Try them next time you roast a main course and watch how a tiny change in slicing transforms dinner into something special.
